Hapytrip 12V USB Outlet Marine Switch Panel Aluminium 2-in-1 — PD3.0 + Dual QC3.0, LED Voltmeter

This compact DIY kit delivers multi-device charging, real-time voltage readout and a protected cigarette lighter socket in a corrosion-resistant aluminum housing. It includes screws, terminals and short wires for a straightforward panel mount. The unit supports both 12V and 24V systems and features intelligent protection against overloads, short circuits and incorrect wiring.

How fast can this panel charge my devices?

The USB module supplies one PD3.0 port (up to 30W) plus two QC3.0 ports (each up to 18W), with a combined maximum output around 66W. That power mix lets you fast-charge smartphones, tablets and many USB-C laptops or power banks, depending on device negotiation.

• PD3.0 port: up to 30W for USB-C devices
• Dual QC3.0 ports: up to 18W each for quick charging
• Total combined USB output: approximately 66W
• Works with PD and QC compatible devices for optimized charge rates

What protections and durability does it offer?

The panel uses an aluminum alloy shell that dissipates heat better than plastic and resists scratches and wear. It also integrates overload, overcurrent, and short-circuit protection plus an intelligent IC that helps prevent damage from wiring mistakes.

• Aluminum housing for improved heat dissipation and durability
• Built-in overload and short-circuit protection
• Intelligent IC guards against incorrect wiring
• Detachable waterproof cover shields ports from dust and moisture

How does the voltmeter and switch make use easier?

The built-in LED voltmeter provides a live readout of your vehicle’s battery voltage so you can monitor system health at a glance. A dedicated rocker button lets you power the USB ports and the voltmeter on or off to avoid parasitic drain when the vehicle is parked.

• LED voltmeter displays battery voltage in real time
• On/off switch controls USB ports and voltmeter to save power
• Blue backlight on cigarette socket aids nighttime use
• Panel can be installed horizontally or vertically to fit layouts
