A bit about External Batteries products...
EXTERNAL BATTERY DEVICES
MORE POWER AND MORE BATTERY LIFE
Our external battery devices or mods take either 1 or 2 batteries. Meaning the batteries can be removed from your device and are not built in.
Our mods take different size batteries but please check the specifications of your mod to see which batteries will fit:
18650, 20700, 21700 and 26650.
Most of our devices will have a USB port to allow for charging while the batteries are still connected. However, we strongly recommend our customers purchase a battery charger as this will help look after and prolong the life of your batteries.
