Dual-port 12V/24V USB charger panel

The JacobsParts PANELUSB-B is a panel-mount car charger with two USB ports that deliver a combined 3.1 A output. It accepts 12 V or 24 V vehicle power systems and is intended for drivers who want to charge two phones, tablets or other USB devices at once from a single cut-out. The black nylon housing includes protective caps for each port.

3.1 A shared across both ports

The two ports share the 3.1 A total, so charging two power-hungry devices simultaneously will reduce the current available to each. The unit provides standard USB quick-charge rates only; it does not support proprietary fast-charge protocols that require higher voltages or communication handshakes. A blue LED indicates power is present, but there is no per-port current display or automatic load balancing.

Check panel cut-out and wiring gauge

Before ordering, verify that your dashboard or console has space for the surface-mount footprint and a small hole for the wiring harness. Confirm your vehicle’s electrical system is 12 V or 24 V and that the circuit you tap can supply the charger’s draw without exceeding the fuse rating. The housing is splash-resistant but not submersible, so choose a location shielded from direct water spray.

Questions about this item

Which panel-mount USB charger version should I pick for a 12 V or 24 V vehicle?

The PANELUSB-B operates on both 12 V and 24 V systems, so a single version covers cars, trucks, boats and RVs without needing a separate model.

What does the 3.1 A total output mean when I plug in two phones?

The two ports share a 3.1 A pool; one device can draw the full 3.1 A or both split it, giving each up to the maximum the device itself allows.

What connection standard do the dual ports use and what limits the charge rate?

The ports are standard USB-A sockets; the practical limit is the 3.1 A combined ceiling and each device's own charging negotiation.
