I've been using 510s forever now and got sick of the battery life and having to carry around a PCC, so I started looking around for bigger 510 compatible batteries.
Naturally, I went to the Ego. I was still concerned that even the 1000mah batteries couldn't provide a full-day charge.
Then I found this:
http://www.myvaporstore.com/Joye_eGo_USB_Passthrough_650mAh_Battery_p/ego-pt.htm
It's a 650mah battery that a mini-USB charger plugs right into. The cable is the same mini USB that my PCC charger used. So basically, I already a charger cord for it in my house, car, and office.
Now, I keep it plugged in when I'm at my desk and in my car, and it doesn't go dead. And I dont need to swap between two batteries.
So, in short, if you're a office guy, this might be the battery for you.
