This charger will not work with the eGo batteries.  You will need the eGo USB charger if you want to charge eGo batteries.

This is the NEW style USB e-Cigarette battery charger and is MUCH better than the older style USB charger. It features a rubber grommet insert (detail shown in photo) which grips the e-Cigarette battery and holds it tightly in the charger. It also has a higher mAh rating so it will charge your e-Cigarette batteries faster than the old style charger. To use simply push your battery into the receptacle until it stops. The LED on the e-Cigarette battery charger will turn red and periodically flash blue. When it turns blue completely your e-Cigarette battery is completely charged.

This USB e-Cigarette battery charger is also FULLY compatible with batteries for just about any e-Cigarette model except for the tiny "cigarette size" models. We have personally tested it with DSE801, DSE901, JOYE 510 (manual and auto), DSE103, RN4075, RN4072, KR808D-1 and KR808D-2.

We recommend the RN4081 USB charger if you want to charge 4081 (NJoy NPRO or SmokingEverywhere Gold) batteries.

It is recommended that you purchase a charger extension adapter if you intend to use DSE801 or DSE901 manual pushbutton style batteries with this USB charger. The button ALMOST inserts fully but the body slightly contacts the button and could cause it to pop out.
