CoilArt's Bron Pod System has an internal 950mAh battery. In addition, it can be charged via its micro USB port. A USB charging cable is included.
Also, there are three different voltage settings, allowing for a maximum wattage output of 25w. Not to mention, it sports a familiar form factor that we've seen before like with the Orchid Pod Vape Kit, so it is rather compact, and easy to carry with you.
