NitecoreNB20000 Gen 3 Power Bank, 20000mAh Fast Charging QC PD Compatible with iPhone, Samsung Galaxy and Tablets with Lumentac USB Charging Cable (Dual USB-C)

This compact power bank with two USB-C ports serves as both input and output, eliminating the need for a separate charging port. It packs impressive power capacity in a small, dense package, feeling heavier than expected, which I appreciate for its substantial energy storage. in a small size This brand consistently delivers reliable performance.

I’ve used the same one for nearly two years now, as I bought it in Dec 2022, it’s gone many miles, charged many things, and hasn’t seemed to have lost any operating capacity! Highly recommend!

I took this battery with me to hike a few weeks on the Pinhoti trail. I was able to charge my phone, garmin watch and headphones at least three times before needing to recharge the battery. The battery itself does take a while to charge but I’m very impressed with its weight and functionality.

Lightest option for almost a full week of charging. Months of outdoor use with no signs of performance drop or damage

I love this thing! I bought it for my trip to Japan. I used this thing day and night. It charges fairly fast, doesn't get too hot (it will warm up though), and can charge items at least 4 times (if not more depending on what you're charging). Totally worth the money. I use it constantly (I like to take it on any adventure where I think my phone or headphones may die) . I think my only issue is it takes forever to recharge it. But if you plug it in before going to bed, it'll be ready for you in the morning!

I bought this brand new for a trip to Japan. It worked while on the plane there. I charged it to full when I arrived at my hotel. The next day, when I needed to use it, it would not charge. I thought maybe it's my cable. I bought it and again, no charge. I thought, maybe I bought the wrong kind of cable, and again, it would not charge my phone. I thought it maybe somehow lost charge while in my bag, so I rented a battery pack at the convenience store so I didn't have to go back to the hotel to charge this pack. The lights are all on, but it still will not charge my phone. Now I have to go to Anker to buy a new one. I read on forums that this is a common issue with this battery pack. I'm very disappointed. Do not buy this pack.

The power bank delivered during the harshest conditions.It is light and powerful. The best of all my power banks.

I love these things. They work well, they're super light, but I would kill for another color option. I spend forever searching for them because they can't be seen in my bags. I will literally take everything out of the bag, look, not find it, except it's actually there, it just totally camouflages with the bottom of every bag I own, black or not. I feel like I am forever searching for these things. Maybe a reflective stripe?I took two of these on a 5 day, 70 mile hike. It was JUST barely enough for my Samsung S22 Ultra (battery saver mode), my Garmin Fenix 6s and my head lamp (Biolight 200). I wish I'd had a third so I wasn't stressing about more charge.
