Hapytrip 4-Port 12V USB Outlet Charger — Aluminium Replacement Socket with Voltmeter, 78W (2×PD30W + 2×QC18W)

Hapytrip's upgraded 4-port 12V USB outlet is a compact aluminum replacement cigarette-lighter socket that delivers up to 78W across 2 PD30W and 2 QC18W ports while showing vehicle voltage on a blue LED voltmeter.

This redesigned aluminum USB socket replaces a standard 12V cigarette lighter and converts one power point into four fast-charging outputs for phones, tablets, power banks, and accessories. Built from durable alloy with better heat dissipation than plastic housings, the unit supports multiple charging protocols (PD2.0, QC2.0/1.0 and more) and works in 12/24V systems found on cars, boats, motorcycles, ATVs, and RVs. A clear blue voltmeter keeps you informed of battery voltage so you can monitor your electrical system while on the road or water.

How fast can this charger power multiple devices at once?

The Hapytrip 4-port outlet delivers a combined maximum of 78W through two USB-C PD30W ports and two USB-A QC18W ports, letting you charge four gadgets simultaneously with prioritized fast charging where supported.

• 2 × USB-C PD rated 30W each for laptops, tablets, and fast-charging phones.
• 2 × USB-A QC rated 18W each for quick top-ups on legacy devices.
• Total combined output up to 78W depending on device demand and protocol negotiation.

Will this work on my boat, motorcycle, or RV electrical system?

Yes — the unit accepts DC 12V or 24V input so it installs on most automotive and marine power systems. Its robust aluminum body and waterproof design make it suited to damp or mobile environments.

• Compatible with cars, trucks, boats, motorcycles, ATVs and RVs with 12/24V systems.
• Aluminum alloy housing resists scratches and dissipates heat in confined mounts.
• Sealed construction and secure mounting reduce exposure to moisture and vibration.

How do I install and wire the replacement socket safely?

Installation is DIY-friendly: the charger ships with a 60cm fused lead, spare fuses and blue terminals. Connect the red lead to the positive terminal and the black lead to the negative terminal; the base also shows + and - markings to avoid reverse wiring.

• Use the included 60cm fused cable and spare fuses for immediate protection.
• Red wire to positive (+) terminal; black wire to negative (−) terminal; product base is labeled.
• Follow the diagram for panel mounting or replacement of a cigarette-lighter socket.

What does the built-in voltmeter tell me, and how is it useful?

The integrated blue LED voltmeter continuously displays your system voltage, helping you spot low battery conditions or charging issues without extra diagnostic tools. It updates in real time as accessories draw power.

• Shows vehicle voltage on a clear blue readout for quick checks while driving.
• Helps detect discharged batteries, charging faults, or alternator problems early.
• Operates automatically when the unit is powered, no separate setup required.

Who is this for: Hapytrip's 4-port 12V USB outlet is aimed at drivers, boaters, motorcyclists and RV owners who need a durable, compact multi-device charger with rapid charging standards and straightforward DIY installation. If you want an aluminum-bodied cigarette-lighter replacement that supports PD and QC charging, displays battery voltage, and mounts nearly anywhere on 12/24V systems, this unit provides a practical, safer upgrade from plastic sockets.
