Description

With the Slim K4, Efest presents us a 4-slot charger with USB-C input. The Slim K4 has four charging slots, which means that four batteries can be charged at the same time with a charging current of 0.5A. The maximum charging current of the Slim K4 is 1A. An LED Status display provides an excellent indication of the charging status at any time.

The Slim K4 was equipped by Efest with the CC/CV charging program. Thus, the batteries are charged evenly and gently at the same time. The Slim K4 also has an automatic charge stop after the charging process is complete. In addition to the automatic charge stop, a 0V activation function is also on board - this function allows deep discharged batteries to come back to life.

Of course, the Slim K4 is equipped with several safety features (reverse polarity protection, overcharge protection, overload protection, short circuit protection) and is CE, FFC and RoHS certified.

The following battery types can be charged with the Efest Slim K4: 3.6V/3.7V Li-Ion/IMR/INR/ICR: 16340 / 18350 / 18490 / 18500 / 18650 / 18700 / 20700 / 21700. Maximum two at the same time: 25500 / 26650 / 20700 / 21700 with protection electronics up to 77mm length.
