Nitecore NB10000 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

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.

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!!

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.

Ordered the item less than than four months ago. Kept in original packaging in air conditioned living space. When I opened the item last night, the rechargeable battery pack was completely swollen and unsafe. The covers on both sides had partially popped off. I will need to dispose of it as hazardous waste, without ever getting to use it.

This thing feels really solid and does exactly what it says it will. Weight feels good and provided cables work great. Capacity seems good, I can get a few phone charges off of one charge up. Excited to take it camping

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!

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

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?
