Joyetech Battery Wall Chargers

[Vapo_Dave]

When I picked up my Ego C Twist kit the Wall charger came with a warning not be be used on 510 batteries.
I just picked up an eVic with another Joyeteck charger and wondered if I need to label the wall charger separate or if it would be safe for the eGo.
All the specs on the joyetech sight say their wall chargers are 5V at 500mA. ...? Why the warning with my kit?

I'm sure its the actual charger cable that comes with the twist not the plug, the USB wire with the box on the end that the battery screws into, thats the part that shouldnt be used, the plug I'm sure is fine....

I think 510 batteries are usually in the 200-400mah range, so if you use a charger cable rated at 420mah(the ones for the ego batteries) it could short out your 510 battery.
