Efest LUC S2 Charger

This is one of the best Li-Ion battery chargers on the market. The LCD display shows each battery’s voltage. Clicking the button on the side will change your charging speed between 500mA, 1A, and 2A. Smaller batteries should use lower settings. Each channel is independent, so charging speed is always fast whether charging one battery or two. With the LCD display and intelligent charging, you can be sure that your batteries will never be over or under-charged. With reverse-polarity protection, high-temperature cut-off, excellent heat dissipation and a fire-proof shell, this is also the safest charger we offer. But the truly amazing thing about the LUC is that it will “resurrect” over-discharged batteries! Have some old batteries that have stopped working long ago? This charger can make them usable again. Comes with an A/C adapter as well as a car adapter. The LUC can also act as a power bank. Simply disconnect the power cord, plug in a USB cable and attach any device that charges via USB. With batteries installed in the charger, the LUC will draw from the charged batteries to charge your cell phone, tablet, etc. Compatible with Li-Ion and IMR cells.

Features:

• Two independent charging channels for 10440/16340/14500/14650/17500/17670/18350/18500/18650/18700/26650 Li-ion and IMR batteries
• Algorithm (CC.CV) charging system
• Optional and adjustable charge current: 500mA, 1A, 2A
• Switchable LCD indicator to display the real-time charging voltage and battery status
• Activation function for over-discharged batteries. The LUC can recover overly discharged protected and safe-chemistry batteries
• Soft-start function avoids damage from a large current surge
• Automatically restarts charging when battery’s voltage (fully-charged batteries that were not taken out from the charger channel) is below 3.9V (batteries may self discharge over time)
• Reverse-polarity protection circuit board
