    • Working great
Color: Black
This battery charges my iPhone much faster than the wall charger. I can get two phone charges from one charge of the battery. The battery itself takes longer to charge, of course.

    • Great little charger
Color: Black
Great little charger. I like the first one I bought so much, this was the second that I purchased. Small and thin, it fits nicely into the internal pocket in my backpack. Charges very fast and offered PD power delivery. Works great

    • BEWARE - Capacity way below advertised specs
Color: Black
I bough this power bank a few days ago. I charged my Pixel 7 phone a few times so far. At first, I noticed that the power bank dropped a lot of % charging up my phone. I thought I had a bunch of apps running in the background while charging thus leading to draining of the power bank's capacity at a faster rate. Today, I had the power bank charged upto 100% and my phone battery was down to 38%. I cleared all the apps and shut down my phone and started charging it. The phone was charged back to 88% (50% increase in state of charge) while the power bank's charge went down to 70% Let's do some math here: Pixel 7 battery size at 100% = 4355 mAh 50% of Pixel 7's charge = 2177.5 mAh 30% of KEOLL Power Bank's capacity = 2177.5 mAh 100% of KEOLL Power Bank's capacity = 7258.3 mAh Advertised capacity = 25800 mAh True capacity = (7258.3/25800) => 28.13% of advertised capacity I understand power banks' conversion loss is due to 3.7 V batteries and the 5 V USB standard. Between the battery and the USB socket is a conversion circuit and this changes the 3.7 V into USB's 5 V. This should lead to actual capacity of 74% of the advertised capacity (3.7/5). Then, factor in the additional loss of another ~10% of capacity. But, this KEOLL power bank's capacity falls abysmally short. With the above numbers, I wonder if this is actually a 10000 mAh power bank which was wrongly sold as a 25800 mAh. I'm not going to take it apart and try to find out. I'm just going to return it back. ... show more

I bought this item several months ago if not a year ago from a recommendation from the project farm guy, but we have been on vacation in Hawaii and have had to use this item multiple times because we can’t find a plug-in. We are abusing our phones with videos and pictures And it’ll take care of two phones in an iPad with no problem. ... show more
