As with most modern electronic devices, Elf Bar takes USB-C charge cords. USB-C charge cords are different than traditional micro-USB cords in that the plug is symmetrical and oval-shaped. Micro-USB cords have an asymmetrical shape with one flat side, which always seems to get inserted upside down on the first try. USB-C cords go in on the first try. With all Huge Elf Bar rechargeable disposables, there’ll be a visible port for a USB-C cord, most often on the bottom of the device—not to be confused with an airflow hole. The Elf Bar Ultra disposables don’t come with a charge cord, though. By now, most people have USB-C charge cords around. If not, you can pick one up from any store that sells electronics, even gas stations and drug stores. As stated, charge the Elf Bar as you would any other small electronic device. All vapes, Elf Bars notwithstanding, are powered by lithium-ion batteries. Practice the same care as you usually do when handling small electronic devices with batteries and their respective power sources.
