Charging and voltage monitoring panel

This dual USB charger panel fits a 12 V or 24 V DC system in a car or boat. A built-in voltmeter with blue, red and green LEDs shows supply voltage at a glance. Two USB ports share a total 5 V 4.2 A output, each port limited to 2.1 A. The rocker switch controls power to the ports.

Universal 12 V and 24 V vehicle accessory

The unit suits drivers who want simultaneous phone and tablet charging plus live voltage indication. It is not for buyers who need Qualcomm Quick Charge, USB Power Delivery or any protocol beyond 5 V 2.1 A per port. It also does not fit installations that require a cut-out larger than 1.47 by 0.84 inches.

5 V 4.2 A shared USB output

The single specification that decides fit is the combined 5 V 4.2 A output across both ports. If your devices demand more than 2.1 A on a single port or require a fast-charge handshake, this panel will not meet the requirement.

Questions about this item

Which LED colour should I choose for the voltmeter display?

The unit shows blue, red and green LEDs; you cannot select a single colour as all three are built into the same display.

What does the 4.2 A total output mean when charging two phones at once?

The charger delivers up to 4.2 A combined; each USB port can supply 2.1 A, so two devices can charge at full speed simultaneously.

How does the 12–24 V DC input affect installation in a car versus a boat?

The module accepts any DC source between 12 V and 24 V, so it works directly from a car battery or a 24 V boat system without extra converters.
