Not too sure if this is stuff you already know, but in case you don't.
Most suppliers have an eGo pass
through that is plugged in through the computer and is usable like a regular eGo battery once its fully charged. It can also be used during the charging so its not like you have any wait time. I
vape with reo's pretty much 100% of the time but I bought myself an eGo passthrough for dripping different stuff at home when I'm in the mood for a change and as a back up in case something (god forbid) ever happened to any of my reo's or my charger.
