NitecoreNB10000 GEN 2 Power Bank, Black

Why did you choose this product over others?:Size and weight. It's a huge factor when considering travelling and reducing weight and size. Its slim, compact design just works. Jon Gadget on YouTube brought me to this charger, and his review also met my needs. A really good price for what you get with superb build quality, functionality, and design.Definitely recommended for travelling and having the option to charge whilst out and about.

Very lightweight of course, only charges my phone once. Recommend.

Small, slim, lightweight. Holds enough juice for a few full charges, and holds its own charge well. Decent charging speeds too

Unparalleled energy:weight ratio makes it perfect for UL hiking. Excellent range of input and output power options allowing for quick top-up during town stops. Both USB-A and USB-C outputs makes it flexible. And the real-world tested efficiency is much better than almost any other power bank. The main flaw is that the remaining power display is imprecise and hard to see.However an even bigger flaw is that it stopped working completely three weeks into a month-long trip.

I'm happy with this. Doing some hiking. Plugged it in for under 30 mins, and got one bar 25% charge, , it's half the size of other battery pack I have. And probably lighter. I'm not 100% sure how fast it takes to fully charge. But with plug I think it will be under 2 hour mark. It's definetly fast than normal one.

Have two of these now.Excellent quality, have been using one or the other every day for over a year now.No issued to report.

This is a very expensive battery. It is light and does work well as a battery, I also like the way you can press button and the charger will stay on to charge devices that draw very low current, eg self stick, razors,, apple watch. Left working normal the battery turns it self off if there is not enough draw on current. You do get through charging, eg plug battery in and phone on output, this will shut off at about 80 percent of phone charge, this all about drawing current so disconnect from mains and fully charge phone.Works ok with solar charger 10w racsack type

Took only 30 mins to charge my Garmin 820 from 60% to 100%. Compact and lightweight(smaller than an iPhone 12 mini and of about equal weight).Using it for backpacking and bike packing
