SMART BATTERY | This device is like if our original 650 Standard Battery went to college! We made it smarter and able to communicate with you, hooked it up with a charger, and gave it a fancy new box.

LED SCREEN | The small digital screen at the bottom of the device tells you your battery % and what voltage level you’re using. You still use the button to control the device.

FLEX TEMP | The Smart Battery offers 5 different voltage levels. To change your voltage, click the button 3x until you reach your desired level. L1 = 2.0V, L2 = 2.5V, L3 = 3.0V, L4 = 3.5V, L5 = 4.0V

TWO CHARGING PORTS | Each Smart Battery includes a USB charger that screws into the 510 thread on the top. It also features a separate type-c port on the bottom (cable sold separately).

BATTERY LIFE | The 650 mAh battery offers a long life between charges. The auto shut off feature turns the device off after 12 minutes, making the battery last even longer! Check your battery % by clicking the button 4x.
