This is the Joye kit many of us have been waiting for. 

The great 510 atomizer and cartridge, running at a safe 3.7 volts, but with a battery that should last ALL DAY OR MORE for most users!

This new Black eGo kit includes:

• 2 650mah batteries
• 2 510 atomizers
• 1 atomizer cover
• 5 blank carts (not shown in picture)
• 1 USB charger
• 1 AC to USB adapter
• 1 carrying pouch
• 1 instruction sheet.

The eGo batteries are 650 mAh.  To get an idea of comparison between the standard 510 battery, the XL 510 battery, and the eGo battery, here are some statistics:

* To put this in perspective, one cigarette takes about 3 minutes to smoke, and there are 20 cigarettes in a pack, so an hour of continuous use is about one pack of cigarettes worth.
