The Efest Slim K1 charger can be used to charge 18650, 20700 and 21700 vape batteries (sold separately), a full list of compatible batteries can be found in the user manual.

The Efest Slim K1 battery charger features a simple LED display to let you know how charged your vape battery is. This simple design also means there are no buttons or menus to navigate, just load your battery into place and plug it in. This charger has the same safety features as other larger vape battery chargers, too, including short circuit and overcharging protection, which means you and your batteries are better protected.

Good (20 May 2023)

Does the job, can’t complain at the price! Good charger overall. Good service at vapeclub

Perfectly Portable (09 November 2022)

The Efest charger I use at home is too bulky to carry around, so this one seriously comes in handy. I chuck it in my bag wherever I go to use with my power bank for an extra sense of security in case my batteries die. The LED screen is also a godsend.
