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.

I took this power bank to Europe with me for two weeks. I charged it every night and it worked perfectly! It was the first time I purchased a power bank for our cell phones. It is slim and easily fit inside my small travel purse alongside my cellphone. I was able to charge my phone while touring or when we stopped for a meal. It was powerful and fully charged my phone quickly. I plan to use it at home when I am away from the house for the day too! It is a good quality item that is well worth the money!!

When my 10 year old 10k mah Anker gave up the ghost, charging my iPhone only once, before needing a recharge, I found the Nitecore via The NY Times Wirecutter. I like the very thin form factor and opted for the v3 with two USBC ports. Will test it out this summer since my phone loses charge rapidly throughout the day..The CF finish is cool looking also

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.

Very nice battery pack, my one complaint is that it's supposed to have an automatic low-power mode where it can trickle charge things but it doesn't seem to work with the devices I have; for instance, a NiMH AA charger that takes a long time to sense the batteries.

Why did you pick this product vs others?:This power bank is small, but mighty! I used to recharge my Apple Watch and iPhone 16 Pro for a week. I was careful to unplug them once they were fully charged, instead of leaving them charging overnight.

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?

This is a great battery bank. It is light weight and very thin. My wife and I use it on daily basis and can easily charge two iPhones and still have enough power to recharge other devices. I recommend it for people who travel because it’s so thin and small that can fit anywhere.
