eSMART QUAD battery charger

The eSMART QUAD CHARGER is the newest innovation in Audioroot's eSMART charger line, engineered to deliver efficient, intelligent, and whisper-quiet battery charging for professional use. Designed for 4-bay simultaneous charging, this compact desktop charger is powered directly via mains AC and is ideal for sound engineers and media professionals who require fast, reliable charging with advanced thermal control.

At the core of the eSMART QUAD CHARGER is a high-resolution 160x128 full-color OLED display that provides real-time monitoring of each connected battery. The interface displays detailed metrics including battery capacity (%), charging current, voltage, temperature, and cycle count—ensuring full transparency at a glance.

This unit features Active Thermal Management, combining a PWM-controlled fan with an adaptive micro-controller that dynamically manages internal temperature. Users can choose between active fan cooling or silent mode. When the fan is disabled via a front panel switch, the charger automatically adjusts its maximum charging current to minimize heat, making it ultra-quiet (10dBA min / 28dBA max) even in critical recording environments.

Crafted from CNC-machined and extruded anodized aluminum, the eSMART QUAD CHARGER boasts a durable, laser-engraved housing built to withstand rigorous field use. Its universal 90-240V AC input and IEC C14 connector offer global compatibility, while delivering up to 150W of power across four charging bays.
