We all need an extra ego!
The ego battery is a pretty tried and true PV. Even the most advanced vapers will have a few of these on standby. They are great as a backup or a main pv. These are small enough to slip into your pocket and go. These should last the average vaper a good 5 hours.
These are Genuine Joyetech and for $8.00 you cant beat that price.
