Very slim profile and lightweight, this battery is perfect for an unobtrusive backup for a phone on a night out. It is also very handy for powering LED holiday lights on my musical instruments. I can attach the battery on the back of my instruments with poster tack and the slim profile allows me to keep the battery on the instruments in their cases. Enough charge to run for 6-9 hrs of shows before recharging. Highly recommend this product.

I took this along with me on a 7 month trip that spanned 4 continents and 19 countries.It worked. It survived the trip.My biggest gripe is that the draw when charging the battery is so low that many/most USB chargers don't recognize that it's even there. So if you want to plug it in overnight, it might not charge. This is entirely due to the usb chargers having power-saving features (a good thing!) and not necessarily a flaw in the battery.... but it is a hassle.Similarly, it charges painfully slowly. The capacity is about 35% of my phone battery but it takes about the same amount of time to charge as my phone does.Capacity itself is as-advertised: very few mAH. It was enough, though, to keep my cellphone functional enough to navigate somewhere after an all-night bus ride depleted my battery. It was enough to recharge a headlamp enough to see a dark path. It was enough to top-off some earbuds. And the best part is that you can actually charge 2 devices at once while also charging the battery (assuming you have enough usb cables). That was really handy.So if you really just want a back-up/emergency battery pack that can add about 30% to your phone's capacity: this is a lightweight/compact solution that works well.

I had two of these and they were great for what they are.Small, light little booster to toss in your pocket when you're headed out the door on a half batt..Add a 3 inch charging cable and you can always get that uber home...

I was looking for a lightweight, dependable charger for my hiking backpack. I would not depend on this charger to charge my phone when hiking. Most of the time it doesn't start charging my phone when plugged in. After multiple time trying to unplug and replug the cable, I could get it to start charging. Then the charger barely charges my phone - 4% in 20 minutes.

It's a compact battery for special use cases, don't expect it to run your laptop or iPad for hours.However, it is lightweight, and has proven quite durable.I use it to keep a pocket bluetooth receiver from running out of power overnight.It has also come in handy as the "extra" extra tiny 5V usb hub power supply that apple insists is nesessary to read a USB-A flash drive with their old lightning connector.This is not a "fast charge" or "smart charge" device that I am aware.It is the older generation of tech, but done well.You may want to make note of the 3 ports on the battery. There is USB-A, USB-C, and that weird "micro-USB" port on it.I just used the "Micro USB" for charging with a magnetic USB cable (sold separately).I think there is an updated version from same manufacturer. Might be worth reading the specs on those charging ports, depending on.what you want to use it for.📟

The media could not be loaded. Charged my Google Pixel 4a from 10% to 99% in one hour, using up most of the juice in the battery bank.However, it takes many hours to charge up the battery bank and it loses that charge entirely in a week or less of sitting unused. Poor battery life. If I expect to need to use the battery bank I need to fully charge it the day or night before. This will not work for long backpacking trips like I'd hoped. 🫤VERY lightweight and small.The C port is bidirectional - both input and output.
