Battery capacity 20000mah its double that of the original battery but i think it performs better as the oem bettery would die after around 3 hrs whereas with this power bank i played for nearly 3 hours and it still had 3 of 4 leds on

I’ve come to the realization that the clip is pointless as long as you have a pocket to put the battery in

This battery bank has enough capacity to charge my phone more than 5 times on the sixth attempt it only charged to about 50 as it was drained of capacity

The auto shutoff when the phone is fully charged though it is not an instant shut off and when recharging the battery bank is a helpful feature

Drawbacks to the battery bank are limited instructions no wall adaptor plug for recharging and a lack of description of the different ports

I did not see any difference when using any of the usb ports to recharge my phone

Also not clear on why there are two different ports to choose from when recharging the battery bank
