The Efest Slim K1 battery charger combines advanced charging technology with versatile compatibility in a compact, travel-friendly design. This intelligent universal charger accommodates an extensive range of lithium batteries while delivering reliable, safe performance for all your charging needs.
Compatible with over 14 battery sizes including 10440, 14500, 14650, 16340, 16650, 17650, 17670, 18350, 18490, 18500, 18650, 20700, 26500, and 26650, this charger handles 3. V or 3. V lithium batteries with precision. When you buy Efest UK products, you're investing in charging solutions engineered for optimal functionality and safety.
The Slim K1's sophisticated circuitry includes multiple protective features to safeguard your batteries and devices. Built-in over-current, over-voltage, short-circuit, and reverse polarity protection systems work continuously to prevent damage and ensure safe operation. The auto-detect charging function identifies battery parameters automatically, while the activation function helps revive deeply discharged cells.
Charging performance is optimised through precise voltage control, with an auto cut-off voltage of 4. 0V (±0. 5V) and auto recharge voltage of 4. 0V (±0. 0V). The 1000mA (±10%) charging current delivers efficient fast charging at 1. A, while maintaining safe operating temperatures between 0°C and 40°C.
The clear LED indicator system provides real-time charging status updates, eliminating guesswork about battery levels. Operating on universal AC 100~240V 50/60Hz input, with DC 5V 1A input/output specifications, this charger works seamlessly worldwide. The included micro USB cable adds convenience, allowing you to charge other electronic devices like phones, flashlights, and e-cigarettes directly through the charger.
Space-efficient design makes the Slim K1 perfect for both home and travel use. The separate charging bay ensures stable charging while preventing cross-interference between batteries. With a minimal standby current of <20mA and CV cut-off current of <100mA, it maintains energy efficiency without compromising performance.
The package includes everything needed to start charging immediately: one Efest Slim K1 Charger and one micro USB cable. Built to withstand diverse environmental conditions, it maintains integrity in storage temperatures from -40°C to 70°C, ensuring long-term reliability.
For users seeking a versatile battery charger that combines safety, efficiency, and convenience, the Efest Slim K1 delivers professional-grade charging capabilities in a user-friendly package. Its comprehensive protection features, wide compatibility range, and portable design make it an essential tool for managing your battery charging needs, whether at home or on the go. The Slim K1 represents Efest's commitment to producing high-quality charging solutions that meet the demands of modern electronic device users.
