  • Product typeAutomobile Chargers
  • Charges three devices simultaneously with dual QC 3.0 and PD 3.0 ports
  • Real-time battery voltage monitoring via built-in digital display
  • Push-button switch cuts all power draw when idle
  • Smart chip protects against overcurrent, overheating and overcharging
  • Fits 12-24V vehicles including boats, motorcycles and RVs

12-24V Car Charger for Boats and Vehicles

The Hamzan charger replaces a standard cigarette-lighter socket with a waterproof panel that fits cars, boats, motorcycles, golf carts, ATVs and RVs. It accepts 12 V to 24 V input and provides two Quick Charge 3.0 USB-A ports plus one PD 3.0 USB-C port for simultaneous charging of up to three devices.

Voltmeter and Switch Add Safety and Energy Saving

A blue soft-light digital display shows real-time battery voltage so low-voltage problems can be spotted before they affect starting. A push-button switch cuts power to the voltmeter and all USB ports when the vehicle is parked, preventing parasitic drain on the battery.

Simple DIY Panel Mount with Basic Wiring

The kit is designed for a panel cut-out and connects to the vehicle’s 12 V or 24 V supply with two wires; no special tools are required beyond a drill and a screwdriver. The ABS housing stays cool, but the installer must ensure a watertight seal around the panel edge and verify polarity before powering the unit.

Questions about this item

Will the built-in voltmeter or switch need replacement after extended use?

The voltmeter and push-button switch are integrated into the sealed ABS housing; no user-serviceable parts are listed, so replacement would mean swapping the entire unit.

What limits charging speed first when all three ports run continuously?

The smart chip manages each port up to Quick Charge 3.0 and PD 3.0 rates, so total output current across the dual USB-A and single USB-C ports becomes the practical ceiling.

How much heat does the charger produce during all-day operation in a 24 V system?

The ABS case is designed not to get hot, and built-in protection guards against overheating, so surface temperature stays low even under continuous load.
