Efest Luc - Mini Single USB Charger
Pickup currently unavailable
The Efest LUC Mini is another representative of the Li-Ion chargers from the popular Efest LUC series. The Efest LUC Mini is a 1-slot charger for individual lithium-ion batteries that can be charged up to 4.20V. It has an easy-to-read LCD display, always shows the battery voltage and works completely without any buttons - insert the battery and that's it. It charges batteries up to 26mm in diameter and 67mm in length. Its charging current is fixed at 1A. The Efest LUC Mini is supplied with power via MicroUSB (5V, 1A), which can be your existing mobile phone charger or optionally available USB power supplies, car USB plugs or a power bank for on the go.
Connect the LUC Mini to a USB power source using the cable supplied. Wait briefly until the self-test is completed and 0.00V is shown in the display and then simply insert the battery to be charged (observe the correct polarity). While the battery is charging, its actual battery voltage is displayed in volts and the V flashes in the display. When charging is complete, the V in the display lights up continuously and the battery can be removed again. If the battery remains in the charger and its voltage drops below 4.10V, a new charging process is started. If you insert a deeply discharged battery, it will first be reactivated with a low charging current and then fully charged as normal.
