The Slim K2 battery USB charger from Efest, the largest brand specializing in lithium-ion batteries. Compatible with a variety of commonly used 3.6V or 3.7V lithium rechargeable batteries of various sizes, the Slim K2 can charge two batteries at the same time, with a smart design that does not require an AC adapter and comes with a Micro USB cable for quick charging anywhere a USB power source is available. Charging status is indicated on the LED indicator, which glows white when charging is in progress and blue when charging is complete. In addition to an overcharge prevention function that automatically shuts down when the battery is fully charged, the device also has a reverse insertion detection function that prevents electricity from flowing if the rechargeable battery is facing the wrong way. This minimizes battery deterioration. High-quality German piano wire is used for the spring, which has been spring-tested to ensure quality. The compact size makes it easy to carry around.
