I would love for Nitecore to make an ultimate charger. An expensive premium unit with premium materials. One that can charge all battery types and sizes. One with the best programming and highest end OLED display. One that runs on 120V or cigarette lighter power. Also fully UL and other agency approved status. I don’t care if it is $200 I just want the best. Nobody makes anything at this level
I would love to see nitecore do a Bike light comparison between the BR35, BR25, and the most popular Bike lights out there for Commuting or road riding.
This man might be the best brand representative that I’ve ever seen. So informative! I don’t even need a tactical flashlight but now I feel like I want one.
Although there are many LED flashlights on the market, I prefer to use a company that is solidly in the business of LED flashlights. Nitecore is IMHO one of the top manufacturers in the business. The research and testing that they do is impressive and makes it easy for me to decide which light and accessories to purchase when the time comes to do so. Informative video. Keep up he great work!
I'd like to see a camping trip video, lol. That'd be amazing. Showcasing all sorts of Nitecore gear; lights, lanterns, power banks, power stations, etc.. All the goodies!
Nitecore batteries are long lasting efficient workhorses! I have one of their 18650s and ive been using it for 5 years now! Still going strong! Worth every penny. 👍🏽🌟🌟🌟🌟🌟
Nitecore fan here. I have several of the latest Nitecore lights and the earlier charge kit. This one looks good, but a bit too expensive. I'd love to win one. Another great review video!
I really loved this design. But why it has been discontinued ? Is it because of out of stock ? or any issue with the product ? If anyone know any link that still sells. Please share
I would like to see stress tests on the i series FLs. Not just to see the breaking point, also to see how hot they can get and if the batteries get damage. Or another idea is diy mods recommended by nitecore for their gear.
I just bought one today and day 1 it works, however: 1) occasionally the battery contacts move slightly even with the strap (twisting motion), so it might get disconnected. Sometimes it starts charging again by itself, sometimes a gentle readjustment js necessary. 2) it get's hot, really hot. Will have to see how it holds up but right now, all I need is a flashlight (either p10i or p10ix, i have both) and f21i charger, cable and spare battery and I have a lightweight setup, easy to replace battery if I need more light or if I don't need it, but need to charge a phone or other device, I am set with minimal bulkiness in my pockets with 10000mAh capacity with 18W quick charge capability. So far I love it, will give it a few practical field tests too before I feel confident in recommending it.
Good portable, fast charging charger that not only charges smartphones but also to compatible flashlights as well! Personally i owned a P20iUV and this combo with the extra battery will definitely help my smartphone and flashlight to last longer on outdoor activities!
I’d love to see a video highlighting lights for every day people. The no thought light people can keep in their junk drawer or glove box and it works when they need it.
I posted this to the nitecore store channel video for F21i too, but wanted to post it here also because I’de love for this idea to gain momentum, and this fantastic tech to expand. -- You guys should add some threading around the edge of the parameter on the top, and then you could have a whole line of compatible attachments that could screw on. For example; you could sell adapters for each of the usb types, that user could snap onto the end of their cord, along with the matching part that screws onto top of battery bank and a it would make it a combination between a magnetic charging cable (that doesn’t suck) and an aviator style connector ☺️ That’s just one idea, but I can think of dozens of other things too. The threading would securely hold things in place (biggest issue I’ve had), and would allow this awesome product line to continue to grow.
Another idea; battery pack slides into/screws in to attachment that gives battery pack a slight flange at the top and bottom of the battery. Then a cord can be plugged in under the top flange pointed down along battery (rather than sticking straight up), and cord could be wound up around the body of the battery. It would turn it into a mini cord reel, with the battery being the center pin of the reel
Love the new fast charge 21700 facility. Have been making a lot of use of Nitecore products over the years for lightweight backpacking. Would like to see a video focusing on the products most suited to that activity
@@NitecoreSG I think you have covered urban pretty well previously. Would really appreciate a bringing together of your products suited for lightweight backpacking over many days/weeks outdoors where weight and size matter. Bringing together charging options (i series 21700 batteries or NB10000) with headlamps (NU25 etc) and small handholds, even mention that tiny knife you do (NTK05). Plus what I don't know about or had considered
I really enjoy Nitecore's approach to showing the world their product offerings. While other's will rely on "social media influencers" that show the different "cool features", Nitecore actually educates and informs their audience. I love learning about why Nitecore designs their lights the awy they do. After binge watching a lot of their videos, one thing always stands out: Nitecore engineers with a purpose, rather than just following "what's cool and trending" in the industry. Their products are very well thought out and built with intent. For me, I'd like to see more of their weapon lights and learn why they were designed the way they were. As for future products, I'd love to see more pistol light offerings in addition to the NPL20. It'd be nice to have some of the features that the TK4, TINI 2, and TUP's possess on a pistol light. To be more specific: one button turbo, OLED displays, and various levels of lighting. Great vid as always MJ. Keep it up brother!
I would like to see more of what kind of Nitcore touchlights that can be used on the 5000mAh battery. Own a Nitcore touchlight and very happy with the product.
I’d like to see discussion of future lights Nitecore is currently working on. I’d love to know what you guys are planning to do with the next P12 iteration and the TM series. My first step into the flashlight world was the Nitecore P12GT, and ever since that day I became addicted. I haven’t found another flashlight as versatile and perfect as the P12GT, including all its newer variants. The combo of throw, spill, power, compactness and just pure design and aesthetics truly make it a masterpiece. My other favorite Nitecore light is the TM26GT. Just an insane amount of power in such a compact and beautiful package. The new TM39 looks interesting, and I might just buy it as my first truly BIG flashlight, since my largest in the collection (although not in length) is the TM26GT. Edit: was correcting a typo, had put 28 instead of 26 which is the correct model number for my light :)
I hope to see the light beam of any tactical long throw light ..(such as P20i) and its flood beam when connected with your recommended filter..so that its flood light cover in small closed area.
I'm looking for a good hands free light that's easy to clip on and off the bill of a hat and at the same time give good brightness and great visibility.
Very impressive product. Would it be possible to move the usb c and indicator leds to the side of the charger allowing the surface to be directly attached to your lantern cap without removing the battery from the harness? That would be incredible.
Been itching to get a new edc light. Would be amazing to see what you (and the normal run of the mill Singaporean) carry and how you use it daily. Would be nice to see how the lights help non tactical people too.
I'd like to see the different run time for normal 1800 lm or 1200 lm flashlight when utilize the normal 5000 mAH batt (i.e NL2150) VS high performance 5000 mAH batt (i.e. NL2150HPi). Especially, at top bright or turbo level. Thanks.
Hi, I am noticing that this F21i was removed from production recently. Why is that? I had to compromise and buy 3 MBP21s for my kit instead. They are a nuisance due to slow charge speed, a less intuitive battery level indicator and only Micro USB compattible.. yet Nitecore store in the USA discontinued it, though it's the more portable and superior charger???
I have F21i and it's interesting solution, but could you make a compact charger for standard 21700 with type-c and quick charger as powerbank. Unfortunately UI1 doesn't have QC and type-c.
Suppose I had 2 of these, 1 at 80% and 1 at 30% and wanted to charge the first one to be full capacity (100%). What would happen if I plugged them in to each other? How would they know the flow of charge expected? I don't understand how the F21i knows when to be charged and when to charge something else. If anyone can clear this up that would be great.
You are so informative and I really like the examples you use. I may see one of these charges in my near future I am really thinking about purchasing the new P20iX. Thanks
Would be cool to see 2 of these chargers (one with a full battery and one with a flat battery) charging each other back and forth. How much charge gets lost in the process each time? Kinda pointless, but would be very interesting.
Of course I want to see more videos like this one. Your very knowledgeable and your way of explaining things are very good. I am having an issue with the money to purchase the light + plus a charger and another battery and charger. I really want to purchase the P20iX but by the time I add everything up it’s $200 or more dollars and I still need to update my other 2 lights pretty soon. I thought that I had seen on Amazon the new battery for about $28.00 but if. Heard you correctly you stated the charger and battery at $79.00. So it would be very easy - not easy like in no sweat - for me to spend 500 - $600 on my 3 lights plus batteries plus chargers to go with them. I have to really think on this but the way things are now my 3 lights use the same 18650 batteries of which I have a dozen or more. But I do want to switch over to the new P series lights but just not sure when I can. I guess jus start replacing one at a time and see how things go. Thanks
When it comes to calamities the Flashlights that use AAA & AA batteries are still the best to have. Nowadays flashlights are capable of using Li-ion battery as well as NiMh st the same time & even Alkaline too. Those flashlights using uncommon batteries will suffer in case of a calamity that will result to blackouts for a month or more.
I just received my order today a mh12s and test it. It's pretty nice but while testing I observed that the head/LED housing got hotter.... I want to know why?..and is it fine to continue to used it even the head/LED housing got hotter?...pls I need an answer
Question, if the i series battery combined w i series light is more efficient, how come the p10i on low at 35 lumens last 38 hrs but mh12s on low at 50 lumens last 45 hrs?

Any chance of a JUST C.O.B. light with 18650-21700 or 25650? Kind of a 180 DEG lantern?
I am impressed ! I think this will help my light when I went night hike or even as an emergency

That’s quite a good idea 👍
Very cool! Almost perfect! Need to add low power charging mode so it can safely charge airpods & other small, sensitive batteries.
I recently bought a Nitecore bike light and got hooked on Nitecore products especially the torch lights, and now this! F21i charger!
I would love to see a Nitecore pistol light. Rechargeable CR123 Batteries.
I already purchase P20i and F21i im very happy, satisfied. 🇵🇭💪
Nitecore batteries are long lasting efficient workhorses! I have one of their 18650s and ive been using it for 5 years now! Still going strong!
Worth every penny. 👍🏽🌟🌟🌟🌟🌟
I used this during the last series of blackouts and it performed as expected! Very versatile design.
Nitecore fan here. I have several of the latest Nitecore lights and the earlier charge kit. This one looks good, but a bit too expensive. I'd love to win one. Another great review video!
I would like to see what gear you carry on yourself, your car, backpack, etc. Would be cool to see an edc video and your personal preference!
I want you to feature some water proofing test or submersion test of nitecore flashlights, also further explain what is ip rating numbers thanks :)
Thats a good one, will cover that in a new video soon!
I really loved this design. But why it has been discontinued ? Is it because of out of stock ? or any issue with the product ? If anyone know any link that still sells. Please share
Not enough sales so they discontinued it
Actually quite keen to see what Nitecore has in store for their new Solar Panels and power stations!
Coming soon! Once we have those on hand will do a review on the whole setup
I would like to see stress tests on the i series FLs. Not just to see the breaking point, also to see how hot they can get and if the batteries get damage. Or another idea is diy mods recommended by nitecore for their gear.
I really need to start getting into nitecore looks like I'm missing out. More smaller edc friendly lights
I just found out about this charger, and now I see that it's already been discontinued. What's the reason for this? It seemed like a great option.
I just bought one today and day 1 it works, however:
1) occasionally the battery contacts move slightly even with the strap (twisting motion), so it might get disconnected. Sometimes it starts charging again by itself, sometimes a gentle readjustment js necessary.

So far I love it, will give it a few practical field tests too before I feel confident in recommending it.
A special about RED light - advantages, different brightness levels, possibilities with nitecore. All the best from Germany!
Keychain Light / EDC Light shootout!

Thanks again MJ! I'm gonna need this cuz I have a P20i, i4000R and three NL2150HPi battery kits. This will make things easier in the field for sure

Would enjoy bicycle lighting discussions

Another excellent review. Thank you! What is coming from Nitecore!!
I would like to see more lights that can be used in biking.
I would like to see more on IP68 rated torches.
Very cool. I can’t seem to find it in the US yet.
I hope to see the different and the likelihood of nitecore P20ix and i4000r.
I would like to see a review of the current IPX8 Nitecore Flashlights available. Thanks! Hope to ser this on the next video 😊
I would like to see a review on the NU25 and how it fits in the range of headlights offered by Nitecore.
Would like to see you pack a full 30L Bag
Maybe when the next BP18 comes out, will do a video on that. The MP30 is phasing out
I would like to see more add ons for this battery system
Would love to see what is the best Keychain size flash light for edc vs full size edc
Informative line of vids. Didn’t even know about the 21700 HPi batteries!
I would like to see a video on highest IP rating torches.
I'd like to see tiniest lights, like the Tube.
I would like to see a video on the best edc flood and spot light combo.
I would like to see more bike light
Been itching to get a new edc light. Would be amazing to see what you (and the normal run of the mill Singaporean) carry and how you use it daily. Would be nice to see how the lights help non tactical people too.
Will do!
I would like to see more i series lineup in the future, look interesting
Would like to see lasers and 21700 powered RGB lights.
I'd like to see the different run time for normal 1800 lm or 1200 lm flashlight when utilize the normal 5000 mAH batt (i.e NL2150) VS high performance 5000 mAH batt (i.e. NL2150HPi). Especially, at top bright or turbo level. Thanks.
The i series flashlights should also work as an powerbank. To charge devices when not in use.
That would be useful, but not the right use for a light designed specially for lighting purpose.
I would love a nitcore pistol light. Capable of attaching to the rail of my glock19
Awesome new charger! Looking forward to next video.
Nitecore lights are awesome
Hi. How long and how many times will this take to charge a fully discharged iPhone that has a battery of approximately 3172 mAh?
Hi, I am noticing that this F21i was removed from production recently. Why is that? I had to compromise and buy 3 MBP21s for my kit instead. They are a nuisance due to slow charge speed, a less intuitive battery level indicator and only Micro USB compattible.. yet Nitecore store in the USA discontinued it, though it's the more portable and superior charger???
Very informative video… you did a great job explaining everything…. You sold me on buying that battery charger… Thank you…
i want to see nitecore flashlight on high lumen mode and long battery life
I have F21i and it's interesting solution, but could you make a compact charger for standard 21700 with type-c and quick charger as powerbank. Unfortunately UI1 doesn't have QC and type-c.
Looking forward for dedicated video on Nitecore keychain flashlights
i would love to see a new version of the EC 20 like EC 20 s or something like this.
great review as usual. good to see usb-c used on this one . now, can you also include ML21 in this kit please please? i'd like to see that :)
I would like to see more lights that can be used in hiking
i would like to see more about mtb or bycicle lights and have more option, i am happy with nitecore br 35 but more options would be awesome
This blew my mind a bit.
I would like to see more battery tests
What kind specifically, any objective?
Suppose I had 2 of these, 1 at 80% and 1 at 30% and wanted to charge the first one to be full capacity (100%). What would happen if I plugged them in to each other? How would they know the flow of charge expected?
I don't understand how the F21i knows when to be charged and when to charge something else.
If anyone can clear this up that would be great.
You are so informative and I really like the examples you use. I may see one of these charges in my near future I am really thinking about purchasing the new P20iX. Thanks
Wait my office bag got some paper clip inside. If thown inside! Will it Explode if paper clip touch + & - charge together? 😲😲 omg!
Now put that 18w 90 min charging into a light.

Note the prices I mentioned are in SGD, not usd so it does sound expensive but actually not
Superb, well explained.
Great video. Great innovative. product. I would like to see more of that power and you used in this video to charge the F21i.
Love your videos
Looks great and a different way on charging.
Great Review from SOUTH CAROLINA USA more chargers I looked at 21700 HPi Lantern and now F21i Charger can they support pass thru charging .

Any chance to get this F21i? I have a battery at home and it’s difficult to charge devices without this elastic band
I want to see TIKI UV video as soon it comes out. Please....
Yes that’s on the list
I have a p30i and p400r 👍👍👍
How to change the Power Delivery between the two F21i and other device (phone) or other power bank, please?
I just got the p20ix 🔥🔥
Its everywhere sold out en telling out of production is there something new instead of this ?
Any plans to update this?
I like to see lights for hobby!
Any specific hobby in mind?

Brilliant piece of kit and a great review. Thx man 👊🏻🙂 I’d like to see more about a camping gear carry.
I’d like to see a Nitecore light with 2000+ meters of throw
Do these giveaways apply to people in america too?
I would like to see a new headlamp :D
Is it possible to use this battery in non Nitecore lights?
wow, I like this, do you ship to Malaysia?
Is there a similar portable charger/powerbank u cld recommend that work with standard 18650s like the Samsung 30q, lg hg2 or the sony vtc5a???
Will this battery make the BR25 light last longer? compeared to the NL2150HPR

I want to know why?..and is it fine to continue to used it even the head/LED housing got hotter?...pls I need an answer
