The eSMART QUAD CHARGER is the latest addition to our eSMART chargers product line. The unit is powered directly through mains AC and features a 160×128 pixels OLED screen and PWM-controlled fan. The thermal behaviour of the charger is automatically monitored and controlled through an Active Thermal Management system. This system uses fan speed or charging current to ensure the quietest and coolest operation possible. When users choose the unit's fan-based cooling, the fan's speed is automatically controlled by the charger's internal temperature. Users can disable the fan's operation with a switch located on the charger's front panel. Once the fan is disabled the integrated micro-controller will adapt the charger's maximum charging current to reduce heat generation inside the unit.
