Great power bank. It charged up fast and charged my I-Phone even faster. I was able to get up to 5 charges on my phone before rechargiing the power bank. It could have been little more but for the price I think it was good enough. I would recommend this to my friends.

This is the second set of these batteries I have purchased. They are slim and compact and the coating has a very nice feel. Most important, they charge my phone very quickly and one full battery charge will recharge my phone at least twice in case I'm away from home and need to charge my phone more than once. I use a battery frequently so I'm often going through the discharge and recharge cycle on the battery. Even so, the battery lasted about a year and a half before it would no longer hold a charge. My wife uses hers less, so fewer discharge and recharge cycles, and hers is still working fine after more than a year and a half. I definitely recommend this battery.

Its not great, just Ok. It will charge a phone but found it picky charging with USB A devices and does not see .5 watt devices at all to even start to recharge. I notice this with a Anker Prime 27650 which showed the power at .5 watts and charged the led light. It was slow to charge with a solar panel as well.

Small compact great power
