Dual USB Charger for 12V/24V Systems

This compact charger fits a universal panel cut-out and supplies two USB ports for phones, tablets or other 5 V devices. The green LED voltmeter shows real-time system voltage so the operator can monitor battery health at a glance. A rocker switch cuts power to both ports when devices are not connected. It is aimed at vehicle and marine owners who want permanent, panel-mounted charging without loose adapters.

Continuous Output Behaviour

Each port delivers up to 2.1 A and the combined output reaches 4.2 A at 5 V DC. The unit maintains this rate as long as the input stays within the 12 V to 24 V DC range and the connected devices demand the current. Thermal limits are managed by the ABS housing; no active cooling is fitted, so sustained maximum load will warm the panel. The rocker switch isolates the output instantly if the installer needs to stop charging without removing cables.

USB Interface Practical Limits

The dual USB-A sockets follow the 5 V USB charging convention and do not negotiate higher voltages such as Quick Charge or Power Delivery. Cables longer than about one metre or thin-gauge wires will reduce the voltage at the device end, so short, quality cables are advisable. The charger draws its power from the host 12 V or 24 V DC system; it cannot operate from AC mains or from a single 5 V source. Buyers who need USB-C PD or voltages above 5 V should look for a different module.

Questions about this item

How much power does the dual USB charger draw from a 12V or 24V system when both ports are running all day?

The unit supplies a total of 5V/4.2A DC, with each USB port delivering up to 2.1A, so continuous load depends on the connected devices rather than a fixed draw from the 12V or 24V source.

What must already be present in the vehicle or boat for this charger socket to function?

A 12V or 24V DC power source and a suitable panel cut-out matching the 1.47" by .84" dimensions are required for installation and operation.

Will the LED voltmeter and rocker switch still work reliably if the existing wiring is older and shows some voltage drop?

The charger operates across the full 12-24V DC range, so it tolerates normal voltage variation in older wiring while the LED voltmeter displays the real-time supply voltage.
