The Keeppower S1 fast charger is the ideal solution for safely and efficiently charging high-capacity lithium-ion batteries. Thanks to its flexible charging bay, the charger is suitable for batteries with a length of 65 to 84.5 mm and a diameter of 18 to 32 mm. This supports common formats such as 18650, 21700, 26650, 26800, and 32650 – even those with integrated protection circuitry (PCB).

Keeppower S1 – Fast charger for large Li-ion batteries such as 18650, 21700, 26650 & 26800

With a charging current of up to 2A, the S1 enables fast charging times without overloading the batteries. The integrated intelligent charging electronics automatically detect the battery type and ensure maximum safety through reverse polarity, overcharge, and short-circuit protection.

An LED indicator clearly and simply displays the charging status: red while charging, green when the battery is full. Thanks to its compact design and USB power supply, the charger is perfect for home, office, or on the go.
