An essential part of any vaping setup, it is of the utmost importance to get the right battery charger for whatever your individual needs might be. With the vast majority of mods on the market today running off of either internal batteries or 18650 cells, this leaves you with two choices depending on what rig you have. Internally powered mods are going to be almost universally charged via USB chargers while 18650 cells should be charged in a power bank. While USB charging is possible with many 18650-powered mods, it is suboptimal both in terms of charge per hour and the long term life of the battery.
