Technical documentation for the Fourharvest USB Wall Outlets identifies them as analog hardware solutions featuring a passive photo-resistor for the integrated LED nightlight. Material analysis confirms a 15A/125V chassis with a DC step-down transformer delivering a shared 4.2A/5V load across USB-A and USB-C ports. The build utilizes standard mechanical tamper-resistant (TR) shutters.
Performance metrics indicate that the primary failure point is thermal stress on internal capacitors during sustained maximum USB load. The unit is strictly analog, with no integrated Wi-Fi or Zigbee protocols for remote control. Installation requires a neutral wire and a minimum junction box depth of approximately 1.5 inches.
If you require individual software-based control of the top and bottom AC receptacles, the Geeni Smart Wi-Fi Outlet offers networked addressability for each plug.
This hardware is an entry-point solution within the in-wall USB smart outlets category for basic residential upgrades.
