The Efest Slim K1 Battery Charger is 100% authentic in performance and quality! The exclusivity behind the Slim K1 Battery Charger is its widespread reputation of being a dynamic charger and more importantly, occupying a sleek body for easy portability.

For starters, the Slim K1 is a single-slot battery charger, so you're able to charge one battery simultaneously at an aggressive speed. The beauty behind the capability of this charger is that you're able to charge different battery types. While charging a single battery, the Slim K1 provides a charging current of 1A and re-powers the battery effortlessly and quickly.

Not to be outdone, the top of each slot on the charger contains an active LED battery level indicator to provide the consistent status of the battery’s charge. The Slim K1 Charger is also equipped with features like Reverse-Polarity Protection, Short-Circuit Protection, and Overcharge Protection, to ensure the protection of your charger and the battery.

Batteries for the Efest Slim K1 Battery Charger are sold separately.
