Hi, Thank you stopping by and for your comment! The DLYFull A4 only has a Test(and discharge and refresh)-function on slot 4. However, in Test mode, you still seem to be able to choose the charge current at least. Hope this provides you some answers. Thank you and have a nice day! /DrMBalmer

Hi there, Thank your for watching the video and for your comment! I have two of these devices installed - in in my own and one in my father's car (installed within a month's time from eachother). They both still work well. The major questionmark is the "SoH - State of Health" value. My father's battery was only a few months old when the device was installed, and the SoH value started at 95% or so, but within a week or two it was down to 80%, and then quickly down to 75%, then 70%. Now it is showing 68%, with the battery being maybe 6 months old. Seems pretty aggressive of a decline on the SoH maybe. But it seems that it falls off quickly form high values and then stabilizes for ever longer periods of time one it gets down to 75% and below. The battery in my car was in a pretty bad shape when installed the BM200 Pro, and it has been showing SoH in the 60-68% range. Now acouple of weeks ago it fell down to 58%. The battery still starts the car, but the cranking voltage goes below 10V when tha car has been in the garage for a few days, and I believe that some battery cell is damaged since the voltage stabilizes at 12.3V within a day after a full charge using a battery charger. My conclusions so far is that the SoH is not so accurate at the higher levels and seems to fall off quickly anyway. Then, once is reaches down to at least 75 % it slows down and becomes more "accurate". Sometimes (rarely, but it happens maybe once a month), it beeps with a "Charging" warning, complaining about the charging system/alternator. It seems to happen when the battery in the vehicle gets 100% charged and the charge voltage seems to drop off from 14+ Volts to 13+ volts. Not a huge deal, but still something that may happen from time to time. The display unit itself I haven't had a need to charge yet even once. The solar cell and internal battery seem to do their job well so far. I am very pleased overall with the devices. Nice to see the actual voltages (which seem accurate enough), and when to charge your vechicle battery manually before it dips too low. The unit generally sits pretty solidly on the dashboard, but if you drive too fast through a corner, it might slide a bit (does not happen in general though) :) Have a nice day! /DrMBalmer

@@TrươngThịHoàngBình-h6t Hi there, Thank you so much or watching the review and for your kind comment; I am happy to hear that the unit has been able to revive batteries! Have a nice day! 😃 /DrMBalmer

Hi, I believe that your observations are correct. having used the keyboard for a while now, I also noticed that the backlight really drains the battery. With full backlight intensity i would say it lasts a week or so (depending on use of course). So, I have made it a custom to turn the backlight off when it is bright in the room. I wish there would be a lux sensor in the keyboard, so that it would only turn on the backlight (and adjust intensity) based on the surrounding light conditions, and keeping the backlight off during the day. When keeping the backlight off, the kayboard does not need to be recharged for one to a couple of months (depending on use). Thank you for your comment and quesion, I hope my answer helps out. Oh, the Logitech MX keys also gets drained quickly with backlight, but maybe it seems to last a few days longer I'd say (but I haven't measured it in any meaningful way though). Have a nice day! /DrMBalmer

@@DrMBalmer In the HP Accessory Center you can enable the lux sensor so that it will adjust the light intensity based on the surrounding conditions, but it will not keep the backlight off during daylight. 😐

You are correct! 🙂Seems like it could be fixed in software/firmware in a future update perhaps. But at the current moment one has to turn off the backlight manually.

@@robertkorth605 Hello there, Thank you for watching the video and for your question! The keys have are very slightly concave (that is, not completely flat and not convex). Compared to the Logitech MX Keys, that one has really large hollows, while the HP one seems almost flat when they are side by side. Hope that helps! /DrMBalmer

Hi again, I uploaded a few photos in a community post, where I have close-ups of the keys, and also a comparison to the Logitech MX Keys. Please check the Community tab on my channel and see the photos. Thank you! /DrMBalmer

@@roxorbeton Hi, Thank you for watching my video and for the tip about the Solar Crook lantern! I looked it up and it seems to be a very nice lantern indeed!

Thank you for your kind and uplifting comment! Yes, the device needs some time to adjust the algorithm it seems, to slowly find a more precise overall State of Health value. My car battery which is not in a very good state (I need to replace before winter for sure) is showing 60% SoH now and only two progress var blocks. The car still starts but the idle voltage always drops to 12.4V and below pretty soon after charging the battery. I haven't had any issue with lost Rf signal even on hot days so far, but I can imagine the cell inside maybe does not like to be in the sun in a parked car for too long with no airflow. Time will tell 🙂 Thank you and have a nice day!

Hello, I am happy you found my 1 hour video and left a comment! :) Don't miss Part 2, also almost 1 hour :D ruclips.net/video/jm2usfuMsXo/видео.html Have a nice day! /DrMBalmer

Hi there! Thank you for watching my videos, your kind comment and for becoming a subscriber! More videos are incoming, so stay tuned :)

I am happy you liked it, thank you for your uplifting comment!

You're Welcome, thank you for watching the review!

Hi there! Thank you for watching the video and your nice comment! I have been using the Nitcore UMS4 and DLYFULL A4 a lot lately, and they work great (most of the time). There are reviews of some chargers on my channel as well DLYFULL A4: ruclips.net/video/HcqUjFKKqZo/видео.html XTAR VC4: ruclips.net/video/aY4pYl9AmZc/видео.html Nitecore UMS4: ruclips.net/video/HrN62GAsq7M/видео.html The Nitecore D4 I have as well, but no video of it yet. It is similar to the UMS4 charger, but I noticed I got some issues trying to chage 16340 cells (Nitecore cells) that aged 5 years or so. They would constantly stop and start charging. If I charge the cells in any of the other chargers mentioned above, it works fine. Apart from that the D4 is a really nice charger. But do have a look at the videos above - I hope those videos will help you out a bit on some of the options at least. The other chargers you mention I haven't had a chance yet to try out, but the xtar dragon vp4 plus I have wanted to buy and have a look at as well - it seems to be an upgrade to the vc4. Thank you and have a nice day!

@@DrMBalmer Thanks very much for your answer, i will watch the video reviews you mentioned now.

Hi, Thank you for watching the video and leaving a nice comment! Be sure to also watch part 2 of the video, available on my channel as well :) Thanks and have a nice day! /DrMBalmer

Hi there, thcnk you for watching the video and leaving a comment! It was quite a while back when I made the video and unfortunately I didn't make any measurements as to the time it stays on and so forth, but I had mine in a closet, which I didn't open too often and I only recharged it once or twice, before the lithium cell inside swelled up - in both of my units. I have planned for a folllow-up video on that and where I'll try to replace the cell inside etc, but that video isn't yet finished unfortunately. I'll let you know when it is though :) Sorry I didn't have a better answer. I would test the lights now for you if I could, but since the battery cells in both my units had to be discarded I do not have the original cells and therefore charge capacity and times at hand to test. So maybe there is a quality issue with these, why they are so cheap (maybe they put b-grade cells inside to get rid of them while still being able to sell a product). I don't know, but at least I have a follow-up video in my plans. Have a nice day! /DrMBalmer

Very often

it will work for few months then the light won't turn of by him self

Hi there, Thank you for watching the video and for your comment! The timer does indeed have a silent alarm feature. Simply set it into "mute mode" by pressing the volume button on the back until the volume is off (indicated by a muthed loudspeaker symbol on the display), and set the alarm countdown. When the alarm goes off, there will be no sound, but the figures on the display will be flashing to indicate time is up. Hope this helps, have a nice day! Kind regards, /DrMBalmer

Hi there, Thanks for watching the video and leaving a comment! Indeed I did publish a couple of updates on this flashligt, including disassembly and battery charging. You can search for "COB" on my channel and you will find the viseos,none of which is the following: ruclips.net/video/ZCNi6jl7GNQ/видео.html Thank you and have a nice day!

Hi, Thank you for stopping by and leaving a comment! It says on the box and in the Quick Start Guide that it should work well also with mobile devices such as mobile phones, although it is best suited to be paired with a PC. But I kind of felt that they could have released an app for smartphones as well if all the EQ and other settings are simply post-processed in software and not in hardware. Thanks for the info on the Sidetone. I must have misinterpreted the meaning of that.

Hi there, Thank you for you kind comment and for stopping by for a watch of my review! I am very happy to hear it could help you in you decision for buying a timer 🙂👍

Hi there, Thank you for stopping by and I'm happy my video could be of help! Spring type timers in all their glory, but they are not very accurate at all times 😊 I've had this timer right about a year now, and the display still looks good with the included batteries, so it should take a year at least or maybe even two between battery changes. However, that probably depends a lot on how much the backlight is used. The chemistry of the included cells had them at over 1.6v when new, and that really is good for increasing the contrast and clarity of the display, so getting batteries of the same type once a year or two should give the best experience I think.

It's all ok brother. It worked out just fine. Great video. I think my videos are getting worse...Lol.

Thanks mate! :) At least I managed to brute-force the 21700 cell into the base, although it required some expensive equipment to do it, lol...switching over to bread and water diet for a while might be necessary maybe But hopefully I will get a lot of good use from it. So far after the full charge, the lamp itself has been running 5-6 hours I think of everyday use and so far still going strong. Don't be too hard on yourself, you just moved. You have to get settled in properly first. :)

HI! Oh dear, yeah, a bit of video editing software gave me a hard time so I had to re-export the video, and it seems it ripped some audio from the beginning it seems. Good that you catched id, I will try to get it fixed somwhow. Will have to try to do a re-export and re-upload maybe. Thanks for the fast info! I did pui a 21700 in there, did I not? :) Glad you liked the music! Test the voltage of which cell? I believe I did test the voltage of bothe the original cell and the 21700, or maybe Microsofts Clipchamp video export failed with even more parts of the output? I must have a closer look what has happened...

Thanks. Your edits we're very clean and well setup. Excellent job.@@DrMBalmer

Thank you, yeah I have been waitig for some parts to arrive for the crazy cordless lamp, and when I was chosen by ReviewClub to test the Bosch mixer I had to take that on first. But rest assured, the lamp teardown and DIY improvement is planned :) Oh, people think Canada is a tropical resort, huh? Here in Sweden it can also get quite cold at times, so I would also very much enjoy such a video about heated gloves and vest. I have a father who's lost some weight and is now often freezing in the winter, and I have a seed of thought in my mind to get him some heated gloves or vest or insoles. Hard to know which would be the most effective. Gloves are maybe the easiest to handle? I see now that you have a winter gear e-bike video uploaded...why did I not get a notification about it...hmmm. I shall watch it soon for sure! Thanks for the compliment on my videos, I am very happy to hear it! 👍I agree, reviews should be focused on practical use, DIY-ability, numbers, results and the process and videos should not be rushed. Of course I am far from scientifically correct most of the time, but hopefully the videos will show enough aspects of the products for everyone to be able to draw their own conclusions as well. That's why I also relly like your videos and style as well - we are indeed on the same track! Lol, yeah, it's always a surprise when having a look at Chinese products from well known budget.friendly sites :) The dramatic musicreally does convey something, both when trying to untie a cable strap and when dealing with interesting Chinese products 😀 Yeah, 41 subscribers on the channel - I am very surprised we are so many, very grateful! Wishing a merry Christmas!🎄

Well a very Merry Christmas to you and your family. I may have a video that may help out your dad. I recently had a fellow e-biker in the UK ask me about winter gear as I ride all year round and have an outside job. -20 to +30 degrees, whatever. So I pumped out a really crappy video in a hurry as the poor guy was dying of the cold with the wind chill on his bike. I made just a quickie with the vest and heated gloves I'm using. I put links in the description but obviously whatever is appropriate to Sweden would make sense. I work outside all day and especially the vest has been a game changer. Hopefully it helps you out. I'm sure your Dad would appreciate it.@@DrMBalmer

Thank you very much! Oh, sounds nice, will have a look as soon as I get a chance. Not every video has to be long or extremely detailed or whatever of course. Quick and dirty does the job in many occasions. What I meant in my previous reply was just that on this video platform it is almost as if people cannot keep their concentration or interest for more than 1-3 minutes. There are RUclips Shorts, but not RUclips Longs, if you know what I mean :) Many channels are for that reason just trying to cram in an entire review or whatever into those 1-3 minutes, and personally I just get stressed and feel like "whoa, slow down and breathe a little" :/ E-biking all year round in Canada, that sounds risky? Here in Sweden as well I see people using bikes in the winter and considering how many of the bicycle roads are not always kept free from snow, it looks very risky. A heated vest, yeah, in such conditions that is maybe the way to go. I shall have a look into that for my father.

Thank you for your kind words. Yes biking is a little risky in the winter but I've been riding motorcycles for 40 years so I know what to look for. It's not the cold, it's the "black ice" you have to worry about. It where there was some water on the road and it flash froze and now it looks like a black spot on the road. You'll go down for sure. As far as your Dad is concerned the good thing about a heated vest is it will keep his core body temperature higher. That's the key. With the vest I purchased it also has heating elements in the neck which sits on the jugular veins in your neck so it's heating your blood as well to increase overall body temperature. If you can't get the specific vest I have I'm sure something suitable that is able to be acquired in Sweden would be sufficient. Usually with these Chinese companies they may change the name but the product stays the same. Same shit, different pile 🙂 @@DrMBalmer

Thanks for the info! You know your stuff if you've been riding motorcycles for 40 years :) Yeah, a vest is probably the way to go. And as you say, many "brands" are just re-branded Chinese ones.

Hi, Thank you for your comment, I am sorry to see you leave, although I can understand why. I will have to look into alternative platforms later on maybe. In the meantime, you're welcome back any time!

Hi, Yeah, I had to check, and to my great surprise it turns out its neither made in Germany nor China. It is made in Slovenia 🙂

@@DrMBalmer 👍

Thank you! Oooh, that does indeed sound like an interesting device - would love to see you showing it in a video! "[...]that is named after a mythical tribe of women warriors", I like your style! :D If the cells are in parallel, is there charge balancing circuitry or does it just treat both cells as it was only one cell? Maybe it is not so crucial in a 2P pack though if the cells drift a percentage point or so. Thanks, yeah I am planning too see if I can improve the battery capacity in that lamp. Next part video should contain a bit more DIY :) Yeah, if you also get one of these, then we would indeed have a sample size of 2 - interesting to see how much the included battery cell capacity will differ.

Hi, Oh, it's that bad...yeah, hopefully the Right to Repair will become even more a thing of the future so that there will be spares for "all" products at least within a reasonable amount of time. I suppose if one can find a broken MX keys somewhere online for dirt cheap and use it for spare parts, that could be a solution to get hold of keys that hopefully look better. The 5 key that stick, maybe it just needs a cleaning with electronics cleaner and/or some oil in the mechanical parts. I had an Asus ROG keyboard a while back which would type several instances of the same letter for "R" I believe. After a clean it worked fine again. Thank you for stopping by, watching the video and for your comment!

Thank you for yourn informative comment! Yes you are right, and i realized a bit later that the difference between the cell voltages were so small that the only real conclusion would be that all chargers did end the charge at a reasonable voltage level at around 4.2V. No charger overchargrd or undercharged the cells, which is good. But as you say, to get the accuracy needed, it would require some more measurements and also test all cells after the same amount of time after the charger days full, since i believe the cell voltage drops a bit after charge cutoff. Thanks for stopping by, watching the video and applying your great comment!

Hi there! I must admit that it sounds a bit spooky - I just uploaded the video a few hours ago! I hope you found the video useful and thanks for stopping by :)

Hi, Thank you very much, very nice to hear from you and your support of my attempts on RUclips! :) That's quite the story with the computer on the wall, haha, and a very interesting and effective level of security with the shorting of the pins I must say! Yes, most systems do get cooled the best in open-air, but there are some cases that which may improve cooling, if air gets directed right into the CPU or GPU cooler fans with some pressure via chassis fans. That's why leaving a solid side panel on a case might give better thermals than running in a case without the side-panel, since the pressure drops without it. Thank you for the kind offer to help out on software and hardware side of things, that is much appreciated! Currently I have what I need to move forward at this pace, but I'll remember your offer! The PSU is an Fractal Design Tesla 800W, but it is 80+Gold rated at least. With the GTX 950 and 960 I believe it should be okay, even with an OC'd system and GPU. I shall have a look at the power draw maybe...but if I manage to get hold of a dual 8-pin GPU in the 1080Ti or Titan class card as we move forward, then maybe I need to up the PSU power a bit. Your words are very encouraging, thank you! I lost my mother recently (just over four months ago and we were very very close), so I have found that working with RUclips channel is having a therpeutic effect, and my mother was happy about me starting a channel so I also feel that I cherish her memory as well by trying my best to continue in the way that I can. Look forward to Part 2 of both the GTX 960 OC and the Green Fan Project video! ;) I have some ideas for projects and I like the Overclocking (yeah, BIOS is the way to go!) so I will do what I can to keep making the videos, and it makes me plenty happy to know that they are seen and appreciated as well =) You have nice videos as well that I really enjoy watching, so once you've settled in after the move, I hope you have some nice ideas as well for new vids on your channel!

Hi, Thank you for stopping by and watching the video! The external microphone I used is a BOYA BY-M3 that I got for my birthday. At one point in the video I switched back to the built-in mic of the recording phone (Huawei P20 Pro), so the difference can be heard.

@@DrMBalmer its good actually + nice content <3

Thank you for the uplifting comment, and I am happy to hear that you like the content! 👍🏻🙂

Hi, Thank you for your nice comment - I am very happy to hear that you liked both the review and the charger! 😊 I have also found that out of the chargers I have, I use the UMS4 the most. It is, despite some flaws, a very nice device.

@@DrMBalmer I am using as I type this. I have a lot of custom flashlights so I go through a lot of batteries. Thanks for the vid again

Thank you! Oh, yes I also had an old IBM clicky keyboard a while back, it worked perfectly and I sold it when I needed the money. Never har a Commodore, but my first PC was an IBM 486 33MHz, also with the nice IBM keyboard. I also feel old at times...

Sorry Dr Balmer I look like a drunker version of Kenny Rogers and twice as old. Lol.@@DrMBalmer

Hi, thank you for your comment! I have changed the subtitle setting for the video so now you should be able to at least activate automatically traslated subtitles in the settings for the video. Please try that and have a look if it seems to work well enough.

Hi there, Thank you stopping by and for the kind comment! I haven't found a way to make the backlight stay on, but I suspect that the battery time would be very short if the light was to be left on. With fresh batteries, the display is still fairly visible if there is some sort of ambient light in the room (such as in the bathroom but leaving the door open to an area which has daylight). But in a completely dark room (such as a bathroom with the door closed), the display is not readable without turning the backlight on.

Thank you for your kind comment, and great to hear that you are pleased with the charger!

Sorry for the late reply, but your comment arrived just after I tragically lost my mother. Also, I am sorry that my voice is not perceived as calming or normal, but rather uninspiring instead (I know that this is not LTT channel). However, I hope that despite my voice, the content overall was ok.

Hi there! Thank you very much for the nice comment, and I am very happy to hear that you enjoyed the video and were able to make a purchase decision! 😀 I hope you shall like the timer as well!

Hi, Thank you for watching the video (and hope you found part 2 update on my channel as well) and for your comment! Yes, I noticed that there are several models/versions of these lights and will have a look at some more of them in the near future. In the meantime, I know @chrissinclair8705 has made a recent video on one such version like you mention. Very handy lights - not perfect perhaps, but fun :) Thanks and have a nice day!

Hi, Thank you for watching the video and for your comment! Unfortunately, I do not have any experience with Dyson. I have been using the Samsung Jet 75 about a year now and it is a good vacuum cleaner, with the pros and cons that I mention in all my videos on the Jet75. Project Farm channel has a nice comparison of many vacuum cleaners, including Samsung Jet and a Dyson model. You can check it out here: ruclips.net/video/RTkUNwBo9Ao/видео.html Have a nice day!

@@DrMBalmer Thanks for response to my comment. I am planing to buy the Samsung Jet 75, i saw alot of bad reviews on Dyson vacuum, i dont want to waste a money for that skräp dammsugare.

Hi, Sure, no problem, I am happy if I could be of help! The Jet75 is a good cordless vacuum, it is not perfect, is not cheap and all that, but all-considered... It has been pretty handy to have around. The Cleaning Station is a nice-to-have thing, not necessary perhaps, but psychologically it has made me want to vacuum more often - it is fun to use and see how the dust is cleared out of the container... :) I hope you'll enjoy the Jet 75 as well!

@@DrMBalmer i just ordered the Jet 75 complete and i saved 3000kr. 😊

@@msbloom6371 Congratulations to your purchase and savings, let's hope you'll like it! :)

Yes, for my test-bench, which is drawing about 135-150W or so being overclocked and under load. It certainly has enough battery power to keep it running for a few minutes until power is restored. I agree, running an office PC and monitor should give you enough time to save your work at least and do a clean shutdown (since the Windows 3.11 software is a bit...well...outdated and perhaps buggy :) ). 25 years computer tech, then I can imagine you have seen quite a few computer errors! Definitely, a small cheap unit like this is probably better than no power backup at all. Yeah, thanks, that's a good idea for a video! And thanks for watching this one! ;)

Yeah, probably not for bitcoin miners :) But connecting a laptop with a bad battery, or network peripherals works great. Right no I have it conencted to the test-bench system, with the monitor and netowrk switch. That system is heavily overclocked as you have seen, but the load level on the unit is pending between 2-3 out of 4 bars. Most UPSes use Lead-Acid batteries as far as I have seen. Power stations using LiFePO4 could be an option, but they can't be set into UPS mode? That is, being line-interactive, or switching to battery power in time when a blackout occurs, so they are more for on-demand power. I might be wrong, but maybe it might be because Lead batteries are happy being helt att almost fully charged levels, while Lithium cells in general are not?

@@DrMBalmer Well in theory I don't think it matters what the power source is if the switching relay is fast enough. All desktop power supplies have capacitors which should give them at least half a second of power before discharging completely. Even a laptop buck convertor should have at least a half second in there before total discharge. As long as the relay can switch within 200 milliseconds or so it should be ok in theory. I guess one way to test it is have a variably timed relay switch with say 0-1000 milliseconds and see what the cutoff is before a laptop or computer is non-functionable.

Hi there, how nice to see you! :)

Thanks! I see, yes there is a lot of testing that can be done as there are a lot of variables: like you mention, the time after fully charged to when you take the cells out of the charger for instance. usually, unless one is constantly monitoring a charge, I suspect the cells can stay in the charger for a while until removed. But yeah, considering the results I got, I too believe all chargers are good and within spec. They are only off with a very slight voltage drop from each other, and were probably even closer together the seconds after a full charge. Oh, yes, those Soshine LiFePo4 batteries that came with dummy cells, I have to look for those :)

@@DrMBalmer I made a short video on USB-C ebike charging I'll post the link to the Soshine AAA battery kit I bought. I believe it was pretty reasonable. You get 4 AAA batteries and 2 Dummies. I paid $19 for it on Amazon so it's wasn't too crazy. It would be interesting to see that Nitecore in action charging it. Do you have a AAA flashlight or does the nitecore have a discharge function to test? Terminal discharge voltage should be around 2.4v. These Soshine ones say that 2.0 is the full discharge voltage cutoff which I believe is a little low and they market them as "recommended for T.V. Remotes" I'm assuming because with a slight overvoltage they will throw the signal farther? It doesn't matter really what you put them in. I used them to boost an EDC01 AAA flashlight to like triple the brightness while staying within the voltage rating of the LED. However a AAA 10440 works with it as well but it gets super hot fast.

​@@chrissinclair8705Oh great, I will have a look during the weekend! Yes, I am pretty keen on those LiFePO4 cells. If you have a link, that would be great. I must have some three cell AAA flashlight... yeah, at least an IKEA one and probably more. I know that I do have a charger with discharge functionality - will have to check if it is the Nitecore or not though. Overvolting flashlights is nice - would love to try it on old incandescent flashlights too, singe then there is only a simple resistive load, and see how it affects the brightness (and build longevity :)) I've found however that you can get dummy AA and AAA cells by searching for "battery AA replacement adapter" for instance. Then you get a power adapter that puts out 4.5V, connected to a dummy AA or AAA cell. You also get two dummy cells for devices that take three, and one special with a resistor inside I guess, for when using with devices using two cells and 3V. That's pretty handy and also you can take the dummy cells for use with LiFePO4 :)

Xtar (and now Vapcell with the S4 Plus V3 and only the V3) have storage modes. It’ll charge or discharge a cell to 3.65’ish kinda depending on whether it’s going up or down. I think it does try to compensate by allowing a charging cell to go up to 3.7X and a discharging cell to go to 3.6X so when the current is removed (for discharge I know it’s a measly 300mA) the cells will all be roughly in the upper 3.6X range. So you can kinda use the Xtar for LFP but be careful. If you have it plugged into a USB adapter that renegotiates it’s going to cause the charger to restart into its normal 4.20V charging mode. Not dangerous though since LFP can technically safely charge that high but you’re just beating the hell out of the cell. Nothing to gain past 3.55 or 3.60 really. That’s why A123 despite being 3.3V nominal instead of the normal 3.2V states max charge voltage of 3.60V. They got it right. Not sure how the Vapcell functions but it’s a beast of a charger just by specs

Hi there, thank you for your comment! I did take a look at that, and made a quick calculation with different battery types. You can watch from 28:53. The time before you want to install new batteries will also depend on when you think the display goes too dim. You're welcome, have a nice day!

Thank you! Yeah, that's great, I also really like overclocking, and it is fun with a test-bench and some older parts that one can play around with! I will have an upcoming cooler swap and see if that helps to get above 5900 points in Firestrike ;) Oh, nice, I will definitely have a look at your video after work :) I have also just received the W5130 light. Haven't had a chance to try it out properly yet, but it does seem a lot brigher for sure. Also got some other variants of light in the same order, so that will be interesting to look at as well. Yes, I would love to see some W5130 "overclocking"!
