2 years later phones have a 7000mAh battery and 125w chargers.
It's been 3 years 🙂
and it happened 😂@@guidezz758

Thought you would put a fast charge circuit IC into the powerbank to charge it with fast charge usb chargers
Me either:)
NE555 clickbait of coz
Clickbait, besides only Qualcomm knows how their circuit works. No one should be messing with Quick charge 3.0, otherwise it would be easy to fry your cell phone.
Nathan Ramanathan not really...
Nathan Ramanathan I know that the USB consortium has their own official fast charge standard unlike Qualcomm's proprietary one. So, he could've just used that standard.
I recently replaced the cells in my power drill battery. Man I love tinkering with electronics :D
If you have a hobby charger, this can also be accomplished by leaving everything attached and adding a JST-XH 3 pin port and XT60 connector. I trust my iCharger 1010b+ over almost any protection board sold so that is unnecessary for my setup.
It would also have been awesome to use a fast charge spoof plug and a buck converter with cc/cv and a balancing BMS to fast charge it via USB.
I hate when manufacturers list false capacities by adding up the capacity of all batteries. 72.36 watt hours, each cell is rated at a nominal voltage of 3.7 and the pack is in a 2s3p config. that means that 72.36/ 7.2 volts (voltage of the pack) equals 10.05 Amps or 10,050 mAh @ 7.2 volts instead of listing it as 20,100 @ 3.7 to make the capacity appear larger for those who don't know. 10,050 / 3 means that each cell has a capacity of 3,350 @ 3.7 volts. Those are usually rated at 3,400 though so I wonder what's going on. Watt hours is it only way to calculate the honest amount of energy in the battery pack.
But what if the icharger protection fails then what will you do
well if youre that unlucky, just say fuck it and move on@@ThatVoxelBlock
LMFAO "since nobody got time for that" 1:20
Necromeming. Reviving a dead meme
Well who the heck want to wait 9 hours?!
Bob dabiuld It's an older meme sir.....but it checks out.
guh huh! he did a thing and i know the thing so i gotta say i knew the thing so everyone that knows the thing can all know the thing together!
Reminds me of those seagulls in finding nemo. MEME meME MeME MEME Meme MEME.
You could just use an XT30 and JST-XH balance connectors and connect those in parallel with the battery pack and use a hobby charger with balance function and forget all of those complicated wiring and switch and BMS and at the end, it'll be simpler and cheaper and easier.
Labs somebody suggest using an xt60 but I was thinking xt30 + balance charging was the better option due to its size and simpler.
The high capacity 18650's usually don't like going over about 3A. So use almost any convenient connector. I'd avoid XT60 on things that can't push more than a few Amps because it's just asking for someone to borrow it to test a quadcopter or similar... and it'll end in tears.
But would the charger not destroy the curcuit without a switch?
Can we use a screw terminal instead
Great video. I own that same Anker Powerbank and charge times are really frustrating.
One possible improvement - Redesign the enclosure with counter-sunk screw holes, or use cap-head screws.
Love the “inappropriate li-ion charger” at 6:24 😅
yeah, can you go see a doctor please
After hacking Li+ battery packs before I appreciate having commercially made safety features! This is a fix to the biggest problem with large older powerbanks. I'm glad most new ones come with power delivery to charge in more reasonable time.
Everyone has a art to do something new, but not everyone has art to explain it to this clear level❤🙂, keep it up🔥👍
Love all of your videos, they're so clearly spoken and interesting to watch :)
noticed him breathing ............ Now I can't get it out of my mind
LMFAO why did you mention it ffs
@@cimkep8250 🤣🤣🤣🤣
Oh God why did you mention it !
I currently use 6x18650 power bank with removable cells. If I need a fast charge, I can replace the cells with charged ones, or clip leads to the battery terminals and use iMax B6 to charge the cells in parallel.
Awsome dear scott!
azeem bhai ap yaha
Mr Engineer are u indian
Acha to ap Ideas yahan sy churaty hain....... :P Hehehehe
Mr Engineer u
I always find it very interesting see different people do electronic hacks. Wish I could do but don't have the expertise or the equipment so I'm forced to go buy a new battery Bank. Enjoy watching the video and see how things are put together even if I don't fully understand.
Or buy 4 x 5000mAh banks so you can charge “in parallel” 😂
My expectation: Wow, now I can use USB Quick Charge adapter with a power bank too!
The reality: Just add XT60 and some protection into the module. And use the proprietary charger to make a "Fast Charge"...
WTFFFFFFFFF!!!!
Technically it works tho 😂😂😂
- Yeah, I agree that it "technically" work.
- Nah, I don't think the old enclosure can take it apart easily w/o destructive process. And, if it somehow can, how you put the wire (must not too small gauge due to current needed.) and the circuit into the enclosure which very crams by the existing circuit(s)?
I like how +GreatScott! make a new one. Just disappointing how he did with the electronic part.
I think this way is better. Instead of some weird proprietary standard, it uses a common method of quickly charging.
Yeah, if you already have a Li-ion charger.
But, TBH, it's less convenient to use than QC charger. :(
Alternatively, just get on Digikey and look for a good integrated charge controller w/ lithium battery protection. I know there is an ultra simple version used on the DD06CVSA modules on AliEx, but the IC is unmarked. I'm tempted to try an acid bath decap to look for a part number on the silicone die but I'm not that motivated yet.
I know some of the newer PIC microcontrollers have integrated switching converters. That's probably an option. Just make your own PCB with a board house like JLC or etch it yourself. ...or do what most everyone does and buy some outdated junk designed module to paste something together.
Would have thought you put in an actual Qualcomm Quick Charge circuit. Anyone here had luck with DIY QuickCharge Solutions?
You can buy USB Pd boards on AliExpress which do basically the same thing.
Nice! I would simply add a balance connector to use with a lipo/lion charger
MrSmoothvideos , I think so . If he break the case to re-solder battery pack. Why he don’t add balance wire instead of waste battery capacity.
Scott. Great video. I had an idea for a video. How about giving life to old power tools by replacing tired Ni-Cd batteries with 18650 lithium cells? How to work out replacement, how to protect them in use and when charging and how to charge them.
You put a lot more effort in writing a 1 than anyone I've ever met.
I had an EXCELLENT power bank that used batteries connected at 12V which then were stepped down to 5V. It allowed charging the bank at ~12V 1A while charging multiple devices and still fast enough to charge the pack. Pretty neat in my opinion! I wonder why most packs input charge at only 5V 😧
Instead of that switch why don't you use a mosfet and attiny85 to toggle between two modes.as you are a genius in programming.😀i would like to see one like that.
Waiting for 9 hours. Talk about dedication.
Great idea that sparked my own powerbank which can output 400W constant and surge up to 1200W, Even running a spot welder from it!! I charge it at a regular 100W @16.8V and max of 300W @16.8V. using 8x 18650-3000mah Howell battery cells. You could potentially build a small circuit with fitting mosfet array and Mcu to manage it by itself. Great job!!
There are few Boards available on AliExpress that let's you charge your power bank through micro USB using Qualcoms Fast charge technology. Those boards also have a fast charge output. Great video as always :D
About 20 minutes before you released this video I searched exactly this feature! :D
I did one up similar to this a couple years ago. I took a typical 4x 18650 cell holder, connected them all in parallel, attached on the USB power PCB I ripped from another bank, then on the opposing end I put one of those XT60 connectors. It's hot all the time, but same principals, it can charge from my lab bench, or I can use another 4x 18650 cell holder, also connected in parallel, to plug into that XT60 to increase the capacity of the bank.
She's not pretty, but she works real well :)
Why not add a balance port? You could handle all the job with the balance charger.
My thought too. Only one charger needed, and faster charging until the end. No switch required.
Probably _"because I'm such a genius!"_
Labs
More likely lowering to the common viewer. If you already own a multi-cell LiPo charger, you probably already know how you can wire up the pack to use it.
Yeah right, because everyone own a lab bench power supply...
Selam bro, qc3.0 desteği ekleyecek sanıp gelmiştim videoya, ilk defa Türke rastladım greatscott kanalında.
is he speaking english?
Are you speaking Spanish?
Yes, are you drunk?
No.!!! Its German i think😅
I love the Sweet Brown reference "Ain't nobody got time for that"
Great video Gerry! Thanks for your time my man
I have an idea for the next project: a high-density rechargeable 9v battery. Something that could power a portable audio amplifier or radio for a few hours, but with the same size as a standard 9v battery, with short circuit protection, and could be charged by either the pins on the battery or a micro USB connector.
I play guitar, and I own a couple of mini amps that use those batteries, but having to buy alkalines gets expensive very fast, and the common rechargeables out there don't last as long as a decent alkaline.
I'd love to see your approach for a solution to this.
You can use a common powerbank and a step up voltage converter circuit (around 3$). Just use the trimmer until you meter 9v in the output and you are done
Hobbyking stocks a 9v rechargeable Lithium Ion battery with micro USB charge input. No idea what the capacity is though.... I suspect less than a standard alkaline 9v, but you could get 2 and charge one while using the other.
You can use a normal power bank and a one of these 5v to 9v boost cables - www.ebay.com.au/itm/USB-DC-5V-To-DC-9V-Step-Up-Module-Converter-Cable-2-1x5-5mm-Male-Connector-GT/152988892078?hash=item239ed93bae:g:kFoAAOSwp0ZazYJ4
Just use an external 9V Power-Supply. The tip with the PowerBank is great too
ZElTGElST what I'm proposing is a solution in the same form factor of a traditional 9v battery, to serve as a drop-in replacement. That's the whole point of the challenge of such an endeavor!
A power bank would make sense as much as using a "wall wart" power supply, and while it's one solution, I'd like to not have anything dangling from the device being powered...
I was thinking about making a new power bank . NOW I get a new idea from this video now i am make a power bank by this idea . Tnx for uploading this video
Using the hobby charger you could add a JST-XH connector and skip the two-stage charging process by having the hobby charger do the balancing all the way to full.
Very cool! I was looking at doing the very same thing recently with my anker charger. Mine is about the same size. You’ve given me enough help to try myself now :)
Glad you liked it. Just be careful with the disassembly of the old enclosure. That can be a bit tricky.
You can simply replace the power bank circuit board to a quick charging suported circuit board that can be brought in couple of buck. That way you can charge you power bank faster aslo you can quick charge your smart phone. But its a nice video . Good work
Good luck finding one. Will you poste a link to one that supports fast charging and is set up for 2S?
www.amazon.in/Charger-Circuit-Dual-usb-Accessories/dp/B075ZCFT6M
I don’t know if you notice but lithium battery’s expand after time so you might want to make the enclosure abit bigger
Dude can you be voice to an assistant im making one love your voice
Bro Anker makes quality stuff man.. My cables have outlasted every other charging cable ive ever owned.
"AINT NOBODY GOT TIME FOR THAT!"
RobTapps88 👍🏻 DITTOS... (its a Rush thing lol)
Seriously, they make truly excellent products. Everything from Power Gear to Flashlights,
Yup... Anker even makes EXCELLENT LED Flashlights!
Made from billet aluminum with precision tooling, their $20-$30 buck flashlights come with a good quality 18650 rechargeable Lihium ion cell and BUILT-IN CHARGER (micro-usb female power input under the removable in the “end cap” / a bi-color LED displays charge status - easy to access but requires the user to carry a micro-usb cable to allow field charging)
The device generates 3 levels of pure white (6500 deg. K) Illumination reaching a decent 1000 lumens in the “high” output selection.
Runs up to 24-hours at “low” (100 lumens) and as low as 2 hours in the “turbo-high” mode and a sad recharge time of approximately 8 hours for a full charge. (with 5vdc /2.5a AC charger USB Charger with the cool ultra-short “flat” cable provided with each light)
The last thing I wanted to include - though each light comes with a usb cable and nice, yet simple lanyard, as well as lithium rechargeable battery...
AND... IF YOUR BATTERY GOES DEAD -> NO PROB!
Simply carry a spare or multiple spare batteries. Charge either inside the flashlight or use standalone charger.
AND... Run out of charted rechargeable lithium batteries? Simply purchase some “Standard NON-Rechargeable CR-123 disposable cells. (10-yr dhtlf life .. approx $1-3 usd@ )
THE LIGHT RUNS PERFECTLY ON 2 CR-123’s for up to 2 hours of perfect light on “high”.
Remember - at around $25 bucks or so.. GREAT STOCKING STUFFERS!
Sorry for the “advertisement”...
LOL
I am a huge Fan-Boy of anything that provides great hardware for a great price.
your "i will see you next time" sounds like how Matt from Demolition Ranch does it at the end
Great Scott stay creative I'll see you next time
Very handy video, I am currently building a couple of power banks as well as two variable bench power supplies, I am building in CC & CV into both but I have one of those battery charging stations that you showed on order, just waiting for delivery.
I am actually a great fan of you. Your videos are just awesome. I enjoy your videos like music 😍.
Make a really small high power speaker! E.g buy the smallest high power subwoofer you can buy, smallest midrange, smallest tweeter (which are already really small) and show us how to make a pocket boom box. Or maybe a backpack boom box. And show us how to take in an aux input and spit it three way (into each speaker)! I hope u consider my idea. Many thanks
for the record anker has a version of this pack with dual micro usb inputs for twice the charging rate. I have one and it works very well.
Cool hack. Makes me glad I bought one with quickcharge built in.
If I need to charge my phone quickly, I normally go to a power bank to grab the power, and then let the power bank fill back up more slowly, rather than charging my phone directly via wall charger. I don't know if that would be the case for most people, but it is in mine with my phone and the best wall charger I could find. I think it may be the fact that it's direct DC-to-DC transfer rather than AC to DC.
It would be better to make a new power bank from raw 18650 cells
And that 2s board and powerbank module would be bought separately
And that housing would be the same
And you would also had your 50$ anker power bank safe
The only guy brave enough to use lions property
nice, you could also use a balance lead so it can be charged with the lipo chager!
You could have put in arduino which checks how charged it is and when it hit certain value, it could switch polarities on relay. Common pin of relay can be put on batteries side. Other two contacts should be connected: 1 to fast charger, and 2 to standard charger
This is cool and all but imho if you want to do fast charge right, you stick a balance port next to the XT60 and use a hobby charger, say a SkyRC iMAX B6 or Turnigy AccuCell to charge it.
At my opinion, adding a simple 3 pin JTS and made a custom charge cable must be better because with it you can use you're normal charger and charge it wihout any problem at 1C or maybe 2C if you want to be really fast.
I love your autro. "Stay Creative, and i will see you next time!" magestic. FYI, could I do the same with some old PC batteries?
Well done. I know this because it made me feel like a complete moron.
I love when you say "I simply...."
You sir, you are on another level. I just wanted to maximize my Blackweb charger.. I got a lesson in "I don't know sh!t."
If you'd like to modify mine, let me know. 😂
if you use a rc style lithium charger you could always add a balance port to the battery pack and use the charger's balance function.
I would really like to see a diy on high powered brushed motor drivers using n channel mosfet and mosfet drivers using Arduino
1:16
Obviously.
It's an adaptive fast charge, it works only if it detects a compatible device, and if it's compatible, it sends 9v rather than 5v, so here it's working at the slow speed.
I love the way you say hot glue.
I like you, especially while you explain principle and theory of working
lovely videos with verry minimalist add and without click baits and shiet ! congrats scott :)
I WILL HAVE THAT IN MY MIND , THX FOR ADVICE... be carefull tho !! MOST OF THEM HAVE SAND INSIDE !!!!!! better check for that too
@ 01:20 "Nobody got time for that" lol
Got recommended this video on the same day i received that power bank as a gift lol
This video gave me the idea to use a "hobby" 4s pack and just wire an xt60
connector to an automotive cigarette plug, then I just plug in a car charger that uses 12-24 volts 😁
Nice! I did the same with a powerbank circuit made for 1S batteries, and put cheap 4x 5Ah 1S LiPos in parallel as batteries instead of the 5x 18650 slots of original case and charge them directly with 10Amps from my 90W LiPo charger. With 1x 2A output and 1x1A output this powerbank can feed much phones. In a wooden case, it also looks awesome with a external display for voltage in series with a button to check it with a press.
I would be interested in using a 4S pack , capable as USB powerbank and as jump starter for my car including also a buck/boost converter to have a simple mobile DC power supply. I really like this chinese for example 200W buck/boost converters with a variable resistor to set max voltage and current. They are running all my Cree CXB and CXA Leds i used in my "projects" as a cheaper LED-"driver", sadly at 100-150W load they need already active cooling, at least i dont like hot heatspreaders.
What about the Idea to make a proper 14-22V pack with at least 30Ah/4-6S, including a 230V or 110V (sinus) AC converter? like a "mobile" 230 or 110V AC "Powerbank"?
Very neat, I’ve acquired quite a few power banks like that one. Great video.
Good video. I have a short list if things that would be cool and useful to see if you could make them please.
How to turn a PC power supply into a useful battery charger. How to upgrade cordless tool battery packs to newer cells and how to charge them inexpensively.
Peshewa diy He does have a video showing how to turn a PC psu into a variable bench psu
A PC power supply can't do constant current without extensive modification, but if you need to charge, lets say 12v car batteries, you can easily modify them to put out some other voltage (Most goes up to about 20-25, but you need to change out the capacitors if you go over 15v usually). I modified an old 400 watt one to charge PB-batteries and it worked like a charm, but by modifying it i removed the over-current protection and burned out the MOSFETs, but it could put out almost 30 Amps, which was great for giving a car a quick boost if the battery was low, and it probably gave a lot more when starting, which in the end burned out the MOSFETs. Saved me tons of times last winter when my car-battery was going dead but i didn't have funds to buy a new one.
This voids warranty if you didn't knew it earlier...🤣😂🤣🤣
Nooo hot glue. The diference B-tween a tinkerer and a designer ;) cool hack though. You are one of my favorite YT-ers. Cheers
Only thing I would have done differently would be to add a balance lead so if I was using a hobbyists lipo charger with balancing capabilities. I could still fast charge while balancing without having to stop just below full and allow the built-in BMS finish the job.
Your throat suddenly got itchy because of your expertise.
I would like to charge that powerbank directly to the powergrid and see what happens.
Nice presentation!
please make automatic captions available. Sometimes I can't understand the way you talk. But I enjoy hearing your voice!
Anker did add a QC option to later models but used different cells in the pack. While the power might be in the safe region it will affect cell life ; not only by the amperage but also the heat. Because the standard rate of charge is so slow there is less heat and with less amps the cells will last a LOT longer... These sanyo/panasonic cells can last you a REALLY long time.. sure ; the charge speeds kind of suck but the fact that you can keep using the powerbank for much longer is kind of worth it imho..
nice video, but why haven't you used a 2S BMS circuit board instead of the protection board?
Shouldn‘t the Wh be equal? When the Voltage gets higher, the Amperage gets lower, so the Wh stays the same. It would be interesting to see a video about powerbanks and their real capacity from you.
Ain't nobody got time for that! Lol.
Nice video!
I like your projects with 18650 Li-ion cells
I realised that on the housing you used a Pozdriv (PZ) bit on Phillips (PH) screws which I did not expect from you :D
That Anker power bank already supports fast charging on the input, you just have to use an appropriate fast charging adapter.
I thought the BMS circuits just drained the parallel pack with the highest voltage until the 2 packs were the same voltage. Charging them independently would require galvanically separated charging modules, otherwise you’d short them when applying to the 2 packs. I wonder if you could use your double-throw switch and separate the series connection, and attach them so that you could switch the packs between 2 series connected packs and one big parallel-connected pack
Hola, anda al vertedero saca de ahí tus proyectos y convierte tu casa a energía renovable. Exelente vídeo y calidad.
This is awesome Scott. Thank you.
You should build a synthesizer of some type. Maybe one off the MFOS website or a kit
The noise toaster is a cool one you could do
Yeah, Im thinking of this since a lot of time. Even I have suggested it in some ocassions. Would be super cool to do his own designs, tho
Stabbed the cells getting the case open!
Nice video!
Seems a shame to break open a perfectly good power bank just to save a few hours charging time. But still cool to see inside one.
Normally you shouldn't need to switch the voltage as normal charger for mobiles like the one you showed in the video with 5v/9v feature is able to switch the voltage automatically according to your recharging device need. If you test it with your usb tester you will see that it works at 5v when the screen is switched on and it turns automatically at 9v whenever the screen or the device is switched off.. I also tried to connect a 9v battery for a try but the result was a yellow triangle on the screen with an esclamative point saying wrong current voltage. So I definately think that the device you need to recharge has to get the voltage it requires during the singular stages of the charging process. Since I found out that there are car adapter chargers with the same feature, I was thinking to build one power bank with a 12v lithium battery pack simulating the normal car power supply and then use it with 12v battery charger.. But I would need a display showing the battery charge level on the screen to better be aware of the right moment to put it in charge.. Thanks in advance if you help me with your knowledge.. It is always good to exchange information each other in order to always getting better. CONGRATULATIONS FOR THE PROJECT.. Very nice anyway.. Do not Think about the other comments, the most of them are Made by idiots who will never be able to use their brains aiming to build something useful which serves a purpose.
that is a lot going on in there these modifications are difficult for me, wish I was electronic engineer rather than software engineer!
Practice makes a man perfect
thats a anker power back,,, they are very good. you have models with up to 9-12 up to 24v output plus usb fast charge. i use them for charge my laptop
It would be awesome if you used your X-Carve CNC to make the case out of metal instead of plastic. Still, pretty useful vid. You basically end up with a battery that doubles as a power bank.
I would, however, add a balance connector. That way I can use a lipo charger and charge the battery properly in a reasonable time, rather than needing a bench power supply or to manually interrupt the charging process.
the cells it contains are very high quality, but i would have made a 3S or even 4S pack with a special charger. Actually i did!
i have to say that talking about charging speed, Powerbank is not equal to Non Powerbank, so P is not equal to NP...
I have a rav 22000mAh power bank. I was going to buy the anker but the Rav offers 5v 6a output over 3 ports. Also it charges in around 6 hours. It has a max input of 5v 2.4a
1) Use sheet metal screws to attach plastic parts. 2) Use Pozidriv bit set for Pozidriv screws.
I think it’d be really interesting to see how well the power banks built in charging circuit handles a large imbalance between the cells. Does it balance by discharging the higher set of cells or does it just discontinue charging the higher set of cells?
It's a good and simple hack but their are also special power-supplies that can use quickcharge from Qualcomm or usb pd 3.0.
It's probably to hard to implement one of these two but maybe for a feature project?
In your DIY powerbank case: No countersunk screw holes? Also, you stripped those screws.
Could you show how to cut down the charging time from being hours to minutes when it comes to recharging huge battery packs that you assembled on your own and the different approaches of one?
" so since nobody got time for that " lmao, youre hilarious.
I just made a 8 battery power bank with 40T's (21700s) about a month ago, really wish I would have thought of this before I put it together.
