From what I understand, charging a 510 battery on a 420 mAh output rated eGo/RiVa charger will damage the 510 battery, but what about charging a eGo/RiVa Battery on a 200 mAh output rated 510 charger? My thought is that it would be ok, but it will take longer to charge the RiVa battery on a 200 mAh rated charger. Anyone care to clarify? Thanks ahead of time!
