Description
The Efest SLIM K1 is a compact single-bay smart charger built for everyday lithium-ion battery upkeep. Its slim, travel-friendly body drops into a bag or drawer easily, while an intelligent auto-detect circuit reads the cell on contact and begins charging within seconds, no mode selection or setup required.
A spring-loaded sliding rail accepts a wide range of cylindrical cells, so one charger covers the common 18650, 20700, and 26650 sizes along with many smaller formats. Power comes in through a Micro USB port, letting customers top off from a wall adapter, power bank, or laptop, and a built-in LED keeps them informed of charging status at a glance.
Protection is handled automatically: reverse-polarity, short-circuit, and overcharge safeguards work alongside a 4.20V auto cut-off, and a low-voltage activation feature can revive over-discharged cells. Flame-retardant housing and a straightforward single-slot design make the SLIM K1 an easy, high-margin accessory add-on and impulse item for any counter or checkout display.
