You can select the different length of the battery. With the standard length of the battery you can have the E-Cig with the exact size of the normal cigarette. It equivalents to 12 cigarettes. With the long battery, you can have longer smoking time per charge. It equivalents to 18 cigarettes. For heavy smokers, we recommend strongly that you order more spare batteries for your convenience.

When the smoke becomes less or the indicator light begins to dark, it indicates that you need to recharge the battery with the special charger.

• To charge the battery:
• Screw and connect the battery with the USB adapter.
• Put the USB adapter into the charger (or into the USB connecter of computer and car charger)
• The input supply voltage of the charger: AC100V-240V, 50/60Hz.

After the battery has been charged for 3 to 4 hours, the battery is fully charged when the indicator light turns green from red. Take the battery out and cut off the charger's power supply.

• Precautions:
• When you charge your battery first time, the indicator light may turn green immediately, as the battery has been charged before shipping to you so that you may not charge the battery at this time.
• When you charge your battery, beware to connect the battery a little tightly in order to make sure the indicator light is on.
