These eGo batteries are all high quality Polymer Lithium ion and available in a 650mAh. We have tested these batteries and can say that 100mAh should give you one hour of Vaping.
So a 650mAh will give you up to 7 hours when fully charged. Click the button 5 to 6 times rapidly to turn it ON/OFF. Automatic Cut-Off Protection if the button is held down for longer than 10 seconds.
Note: Only use the wired USB charger with this product.
