NitecoreNB10000 Gen III (Gen 3) Ultra-Slim Power Bank, 10000mAh QC Quick-Charge Dual USB-C Ports for Phones Flashlights and Headlamps, with USB-A Adapter and USB-C Cable, Including NitecoreS Sticker

I’ve been using this for the last several months. It’s slim, charges quickly, and has peaked my interest about the other models they have available. After purchasing, I realized they sell a small flat charging cable, which I still need to get. I’ve been using a different brand of cable. In weather from about 20° to 70°, it charges quickly and efficiently. Above that, it will get worm too hot and slow slows down charging your phone due to heat. That is a positive as it’s showing thermal management is working properly. Just make sure you keep it out of direct sunlight.I try not letting my phone go much further below 20%. On average, I charge my phone from around 25% to 80 to 90% and get about 2 1/2 charges out of this battery. A recharge the battery at home and a quick wall charger, and it usually takes roughly about an hour.Out of all my battery banks, this has become my favorite for every day use.

Edit: it's kind of a fine tuned item.... I just powered up a Pixel 9 from 15% to 35 % in 5 minutes, while running YouTube. Tiny bit of heat, but the best quick charge up ever if you're in a rush. Don't leave it unattended though.Original: The size is great, the charging speed is unbelievable..... my only problem with it is that it gives off a ton of heat when in use and I worry that it can be a potential for a fire hazard. Is that supposed to happen?

I frickin' LOVE this thing. I travel a lot and a friend who travels even more than I do recommended it to me. It is half the size of my old Anker charger but holds more power. It charged my Galaxy phone to 85% twice and still had a bit left over. It stays cool even during pass-through charging. It's awesome.

I got one when they first came out and was pretty excited, had seen every backpack channel and YouTuber raving about the gen2 and hyped about the gen3. So I finally decided to step out of the $20 battery banks and snag one. Extremely disappointed though. I MAY get 2 full charges on my iPhone 16pro max from 20%-full. Tried a few just tests from multiple devices and overall I thought I honestly got a bad one because of how bad it was. So I ended up swapping it for a new one through Amazon and got the same results. For reference I have 2 Anker 10,000mah banks and get almost 4 full charges from 20%. I’m not an electrical engineer so I’m not sure if the Anker are higher mah than stated or the nitecore lower mah than stated. A friend recently got the gen3 20,000mah and get about 2.2 charges on that one with the same make and model phone. I ended up being able to keep the first battery and it got so warm at one point the carbon piece popped off on one side. Just very disappointed after all the good things I had seen and finally pulling the trigger on the new one. I have a 10,000mah “VEEKtomx” I paid under $20 for that works way better also and it’s just an old school usb- usb-c cord I use. Is the weight good, I guess. But overall for the price there’s no way I’d ever suggest this or buy another bank from nitecore unless something improves or changes. I guess there’s a chance we got 3 batteries that were faulty but I see that unlikely. Love their UL headlamps though, but as far as battery banks go I’ll stick to Anker for now until something changes. And maybe it’s also my own fault for just going off of seeing others use them so much and not doing a little more research first. Looking at multiple reviews and comments on YouTube now that they’ve had the gen3 out for a bit now, it seems I’m far from the only one that has that opinion. Again just my personal experiences and opinions here I’m not affiliated with any of the companies I stated but when it comes to cost and usability I can’t see suggesting it. It’s good for an overnight trip if you only need to charge a phone once and your headlamp, but is it worth $60-$75 when you can get a better one for under $30 that performs better at a few grams heavier?? You be the judge and I guess that it depends on if you’re counting grams backpacking.

I bought this charger for use while back packing, to keep electronics easy to go. It is a bit expensive, and the warnings about breaking it if dropped make me nervous given how I use it, but so far it is working well. I have charged an older iPhone and an InReach from it with no trouble, or an iPhone twice, so it is meeting my needs. I do wrap it in some socks inside my backpack to protect it.

Have used this on a rough 6 day backpacking trip and it held up incredibly well. Best bang for the buck battery pack out there.

By far, the best power bank I’ve ever purchased!!! Small and lightweight, with incredibly fast charging! It takes my iPhone from 9% to 100% in less than 20 minutes…it’s insanely speedy and stays charged for hours. Perfect for travel or anytime you’re on the go! I HIGHLY recommend this charger!

I love this lightweight power bank for backpacking! I have taken it out multiple times and it performs flawlessly. When it goes out I would but another.
