Nitecore NB Air 5000mAh Ultra Lightweight and Slim Power Bank, USB-C Port for Phones, Smart Watches, Earbuds, Flashlights, and Headlamps

Great small and light powerbank. So far no issues with it, and no durability issues. I keep it in a waterproof bag in my running vest to charge my phone or headlamp in emergencies or on long ultras.

These are perfect for our backpacking trips. Very lightweight and plenty of power. Charges well with my small solar panel

Super lightweight charging block for gram weenies. That is, lightweight backpacking. Good output, super fast charging and is seriously light.

As a backpacker I was hoping this would solve weight issues but sadly it doesn’t do a good enough job. (1) only one port. (2) it barely charges an iPhone to a full charge. That one charge drains the bank. Realistically, it’s only good for an overnight and that’s if you have nothing else to be charged.

Currently experiencing issues with this power bank while charging iphone 15 plus. Charging stops and restarts repeatedly (shown via battery life indicator flashing on phone) after transferring around roughly 20%-25% of charge. In process of testing different cables to narrow down the problem. I use this same cable with a anker power bank on power delivery with no issues though. Will update once I narrow what's going on.Update: pulled out the original iphone cable, still happened. Also tested an Anker cable, same problem. Ran a test, was at 7% on phone, battery bank fully charged. Problem started at 25% on phone. Unplugged for 5 mins. Plugged back in, seems fine but then problem happened again at 40% charge on phone. Did the same thing, happened again at 51%. Not reliable for my needs, can't be sitting there baby sitting it. Back it goes unfortunately.Updated: Did a warranty exchange and replacement seems to be working just fine now.

Absolutely love this super thin 5000mAh power bank. Photos and videos don't do it justice just how thin and compact it is. Construction quality is top notch. Full fast charging speeds tested with my iPad. Love it for hiking without feeling the extra weight. Will be getting another one to use for my Fiio BTR17 portable dac amp. Well done, Nitecore.

Relatively light, compact, effective. Great for use while traveling. Looks and feels premium.

Perfect for EDC kits. This is about the thinnest and lightest USB-C power bank.
