Detailed overview: XTAR VC4 battery charger with LCD screen
The XTAR VC4 is a smart 4-slot cell charger, popular with users of rechargeable cells: torch owners, vapers, modellers or electronics enthusiasts. Its great strength is its versatility: it accepts both lithium-ion cells (18650, 26650, 21700, 14500...) and Ni-MH cells (AA, AAA formats...), letting you charge most of the home's cylindrical rechargeable batteries with a single device.
Its main asset is its informative LCD screen. Where a basic charger just has an LED, the VC4 shows in real time, for each slot, the voltage, the charge current, the measured capacity and progress. It is a real plus to monitor cell health, check their real capacity or spot a tired battery.
Each slot works independently: the charger automatically detects the type and level of each cell, adjusts the current, and stops on its own once fully charged, avoiding overcharge. It also has a recovery function able to restart charging of very deeply discharged cells, which other chargers detect as dead.
USB-powered, it is easy to use at the office, at home or on the move with a simple mains charger or a power bank. Well built and reliable, the XTAR VC4 is a sure bet for anyone who regularly uses rechargeable cells and wants a charger that is versatile, safe and informative.
