This is the basic Kangertech 510 battery unit which has a big 1000mAh battery and constant output voltage of 3.7V. It’s well built and very reliable. It comes with a ego 510 charger so you don’t need to purchase it separately.
Save money by purchasing the starter kit which includes either 1pc or 3pcs 510 1.0ml cartridges.
Black or silver carts will be given depending on the colour you choose.
