NitecoreNB10000 GEN 2 Power Bank, Black

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.

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

I own 2 of these with another on the way. I have so far used them on the Southern Upland Way which is a 220 mile route accoss the hills coast to coast in Scotland. These items have worked without problems and as advertised in 15 days of walking and wild camping. I charged them with a wall socket and with an Anker solar panel throughout the backpack and they did not let me down. I do agree with the comments about the status lights though - room for improvement there.Bottom line: The best and lightest power bank you can buy for long distance backpacking full stop.Pro Tip: When you buy any power bank make sure to charge and discharge the item 5 or 6 times before setting off on a trip. An electronic item will almost always fail at the start or end of its life cycle.

This stuff works only for short time! Aftermarket service only answers calls and tells that someone will call and never called back!

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.

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.

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.

Excellent device, small and light.
