Efest LUC Mini: 1-bay USB Li-Ion battery charger with LCD display

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-bay charger for single lithium-ion batteries that are charged up to 4.20V. It has an easy-to-read LCD display. It has an easy-to-read LCD display, always shows the battery voltage and comes completely without any buttons - insert the battery and good. It charges batteries up to 26 mm in diameter and 67 mm long. Its charging current is fixed at 1A. The Efest LUC Mini is powered via Micro-USB (5V, 1A), which can be your existing mobile phone charger or optional USB power supplies available from the accessories range, car USB plugs or even a powerbank for on the go.

Operation:

Connect the LUC Mini to a USB power source using the cable supplied. Wait briefly until the self-test is complete and 0.00V is shown in the display and then simply insert the battery to be charged (note 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 permanently 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 is first reactivated with a low charging current and then fully charged as normal.

Compatible with the following Li-Ion batteries:

LiIon IMR, ICR, INR (3.6/3.7V nominal) up to 4.20V
