Description
The Efest LUC S2 is a versatile two-bay smart charger designed to make charging rechargeable lithium-ion batteries simple and easy to monitor. Its clear LCD screen displays the selected charging current, battery voltage and charging progress, so you can quickly check the status of each battery.
Both charging bays operate independently, allowing two different compatible battery sizes to be charged at the same time. Selectable 0.5A, 1A and 2A charging speeds give you the flexibility to prioritise gentler everyday charging or faster results when needed. The built-in USB output also allows the charger to function as a portable power bank when a charged battery is installed in the appropriate slot.
