These batteries are duds and didn't charge beyond the 2lights of the 4 -- and when left plugged in over night, they became hot and still didn't charge.

Pinging a tower that 80k people are also pinging, all at the same time, really kills the battery

This battery is fantastic

This used to be my favorite battery pack, but I am so tired of how tempermental this battery pack is to recharge with its OWN cords
