Greetings All 
I`m looking at a 650mah passthrough & a regular 1000 mah (Egos).
The 650mah will give me a few extra hours to my collection & a passthrough option (is this really safe to use on laptop & will it really charge). It is more compact.
The 1000mah will take longer to charge but provide extra vaping hours unplugged. It`s a huge battery.
Ahhhhh, I can`t decide between the two.
Thanks for letting me brainstorm.....any other advantages or disadvantages you can add....
