I love my pcc and it does charge 5
batteries before the case needs charging.
No battery discharging problem.
No pin problem.
Even charge my choice elite
batteries in it with a pad in the lid to push the battery down. I got the pcc before I got my 510.
I am
vaping my copper 510 from healthcabin. It has no led, which was a misunderstanding when they first ordered them they listed as having a blacklight led. Turned out no led. It is a cool looking ecig.
