Very thin and light battery pack, excellent for travel. It charges fast, and holds enough battery to charge multiple phones. Just what I needed

If you want a great 20W battery, this is the one to beat, its super light and works great. No issues with it, its smaller and lighter then my other 10k batteries and works great. If you want high wattage look elsewhere but this one is fantastic for lightweight and pretty quick charging. I've used it with my steamdeck, phone, computer and others, although its small/slow for my high draw devices such as the steamdeck and laptop, but it gives you a little boost if you need it.

I bought this unit to use as a semi-permanent power bank for USB powered piece of musical gear. When I connected a USB cable to the NITECORE, the indicator lights lit up. I thought that was odd - because I didn't hit (what appears to be) the power button.Turns out the button isn't for power - it's for 'Slow Charging Mode'. Inserting a USB-A cable turns on the NITECORE power bank. I decided to leave the piece of equipment turned off but plugged in via a USB-A cable to the NOTECORE and see what would happen.Overnight I see the indicator lights have dropped from 3 to 2. I expect that the NITECORE would be drained before today is over. That's with the connected device turned off.To use the physical insertion of a cable into the NITECORE as the means to power on the battery pack is... certainly a design choice. A questionable one, I'd say. This is made more confusing by the button featuring the common icon for 'power' really being what they call a 'mode' switch.As of this writing I am not sure if I'll keep the unit. Unfortunately I threw out the packing material, figuring it would work as expected.

i love everything carbon fiber. This charger works and looks great. Weird issue where sometimes it stops charging but doesn’t bother me much because you just hit the button and its back on. I added a MagSafe ring to hold it on my phone.

Very compact and thin; great in a pinch for power backup. Easily drops into a pocket or small pouch; about the size of a smartphone; multiport options are great: USB A, USB C. Lots of power in a small package. Perfect for a long day out and about, etc. Charges almost any kind of small device. Not sure about longevity, but so far it is good. Added grip tape (Amazon GT-5000, $9) for nonslip and grip; now it's perfect.

I bought the black one a few months ago and it is the perfect unit to carry while traveling. It's thin, making it compact, and very light.It's good for two people for day trips.We decided to go to Europe this year so we bought the NB2000 (20,000 mah version) and upon receiving, its noticeably heavier. We we tested it during a short weekend getaway, we noticed that it had intermittent charging. It would stop after about 30 minutes.We returned it and decided to buy another NB10000, but this time in silver carbon. It helps differentiate the two that we now have. The two of them combined is still a tad lighter than one NB20000.
