The Airistech Vertex is our best selling 510 battery. It is very reliable and comes with a lifetime warranty. You can change voltages with 3 clicks of a button, and activate preheat with 2 clicks. It works with every 510 cart. It charges by USB-C at the bottom of the pen so you don’t need to remove the cart to use the conventional ego charger. Save money by purchasing the starter kit which includes either 1pc or 3pcs 510 1.0ml cartridges.
