Reviewed in the United States on December 21, 2023
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 received the first one of these little batteries yesterday. It was fully charged. My smart phone was at 76% charge so I hooked up to the little battery and I was surprised that it charged my phone to 100% in about 20 to 30 minutes and it still had some charge left (one light was on.). Then I charged the little battery. That took 60 to 90 minutes. When it appeared that this battery bank would work well, I ordered a second one. By the way, the four charge state lights work very well. They blink while the battery is being charged.
Because our helmet intercom systems can be used while they are being charged, we can hook them up to the intercoms with a charging cord and just slip them in a pocket while using the intercoms.
So it appears that these little battery banks will do exactly what I needed them for but I will update this review if they fail or there's other problems with them in the future. But for now, I'm happy with them.
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.
