12V USB Outlet Boat Accessories Marine Switch Panel Plug

Hapytrip's 3-in-1 marine switch panel combines a PD3.0 + dual QC3.0 USB charger, LED voltmeter, lighted 150W cigarette socket and waterproof toggle switch into a single aluminum alloy module for boats, RVs and trucks.

This compact DIY kit gives you fast charging, real-time voltage monitoring and a high-power 12V/24V socket in one panelized unit. Built from aluminum for better heat dissipation and durability, the module includes wiring, mounting screws and a detachable waterproof cover so you can install it horizontally or vertically in dashboards, consoles or panels where space is limited.

How fast and flexible are the USB charging ports?

The charger integrates one PD3.0 30W port and two QC3.0 ports rated at 18W each, sharing a maximum combined output of 66W. It supports a wide range of PD and QC compatible phones, tablets and accessories so you can top up multiple devices simultaneously without sacrificing speed.

• PD3.0 30W port for rapid USB-C charging of phones and tablets
• Two QC3.0 18W ports for fast charging older QC devices
• Up to 66W combined output to run multiple devices
• Built-in intelligent IC for safe, optimized charging

What does the voltmeter and switch control do?

The integrated LED voltmeter displays real-time battery voltage so you can monitor system health at a glance. A dedicated button switch powers the USB ports and voltmeter, letting you shut them off to avoid standby drain when not in use.

• Continuously reads 12V/24V system voltage for simple diagnostics
• Button switch prevents unnecessary power draw when idle
• Visible LED readout for quick checks in daylight or low light
• Voltmeter and ports can be wire-controlled via included wiring

Can the 150W cigarette lighter socket handle accessories I use onboard?

The lighted cigarette socket supports up to 120W at 12V and 150W at 24V, suitable for many portable devices such as dash cameras, small vacuums and air inflators. A blue LED ring helps you locate the socket at night, and the socket includes overload, overcurrent and short-circuit protections for safer operation.

• 120W (12V) / 150W (24V) max power for small high-draw accessories
• Blue light around the socket for quick nighttime access
• Waterproof cap keeps contacts dry and dust-free when not in use
• Safety protections prevent damage from wiring faults or overloads

How simple is installation and where will this panel work?

The kit ships with three short wires, mounting screws, terminals and a 3-in-1 panel for straightforward DIY mounting. It can be installed in boats, cars, RVs, ATVs and other 12V/24V vehicles with either horizontal or vertical mounting orientations.

• Includes screws and wires to save on additional purchases
• Panel fits standard dash cutouts or custom mounting holes
• Detachable waterproof cover for outdoor or marine use
• Designed for easy wiring to battery or fused accessory circuits
