Two black 12V sockets with three USB ports, blue voltmeter display and push-button switch

Hapytrip 2 Pack 12V 3-Port QC 3.0 PD 30W Voltmeter Switch

SKU CH-2N8R-P6P72

Two-pack 12 V to 24 V socket adds three USB ports — two QC 3.0 and one PD 30 W — with a built-in voltmeter and on/off switch

  • Two-pack gives you two complete charging stations for multiple vehicles
  • Three ports per unit charge three devices simultaneously at full speed
  • Real-time voltage display monitors battery health to prevent starting issues
  • Push-button switch cuts all power draw when ignition is off
  • Built-in 10A fuse and smart chip protect against overcurrent and overheating

Dual-Pack 12 V Car Charger Kit

This pack supplies two identical 12 V chargers, each offering two Quick Charge 3.0 USB-A ports and one 30 W Power Delivery USB-C port. The set is intended for drivers who want to charge up to three devices at once in cars, motorcycles, RVs or marine craft without buying separate adapters.

Real-Time Voltmeter With Off Switch

A blue soft-light digital display shows the vehicle battery voltage continuously so low-voltage conditions are spotted early. A push-button switch cuts power to the voltmeter and all three USB ports together, stopping parasitic draw when the vehicle is parked.

Fused Lead And Smart Chip Protection

Each unit ships with a 23.6-inch red-and-black supply cable fitted with a 10 A fuse that guards the wiring against overloads. An internal smart chip identifies the connected device and manages current to prevent over-current, over-heating and over-charging on every port.

Questions about this item

How do I wire the 23.6-inch red and black cord with the 10A fuse into a 12V panel?

Connect the red lead to a fused 12V supply and the black lead to chassis ground; the inline 10A fuse protects the circuit, then press the push-button switch to activate the voltmeter and all three USB ports.

What part will need replacement first if the charger stops working?

The 10A blade fuse on the 23.6-inch supply cord is the only user-replaceable component; swap it with an identical 10A fuse if overload protection trips.

At what combined load does the 30W limit appear when all three ports are used?

The charger delivers up to 30W total across the two QC 3.0 USB-A ports and the PD 3.0 USB-C port; drawing more than 30W combined triggers overcurrent protection.
