Audioroot eSMART QUAD Battery Charger
Four smart batteries charge at once on the Audioroot eSMART QUAD, a desktop battery charger that runs directly from AC power and delivers up to 2.0 A per bay.
A 160 × 128 full-color OLED shows each battery’s capacity, charging current, voltage, temperature, and cycle count.
In normal use, the fan changes speed with the internal temperature. A front-panel switch turns the fan off for quiet rooms, and the charger then lowers the maximum charging current to limit heat. Noise runs from 10 to 28 dBA.
The housing is anodized aluminum, CNC-machined and extruded, with laser engraving. Power comes through an IEC C14 inlet, with 90 to 240 V AC input and up to 150 W across the four bays.
