Two-pack dual QC 3.0 and PD 3.0 car charger

This pack contains two 12-24V sockets, each with dual Quick Charge 3.0 USB-A ports and one PD 3.0 USB-C port. It is designed for drivers who want to charge up to three devices simultaneously from a single panel cut-out. The units suit cars, motorcycles, boats, golf carts, ATVs and RVs with a 12V or 24V electrical system. Buyers who need more than three ports per socket or a dedicated high-wattage laptop supply should look elsewhere.

Integrated voltmeter and push-button power switch

A soft blue digital display shows real-time battery voltage so you can spot a weak battery before it leaves you stranded. The push-button switch cuts power to the voltmeter and all three USB ports at once, preventing parasitic drain when the vehicle sits unused. No fan or active cooling is mentioned, so the ABS plastic housing relies on passive heat dissipation during normal charging loads.

Waterproof panel-mount design with DIY wiring

Each socket is rated waterproof for exposed mounting on dashboards, handlebars or console panels. The ABS case stays cool to the touch and houses a smart chip that identifies connected devices to deliver the fastest supported charge while guarding against overcurrent, overheating and overcharging. Installation requires a suitable round cut-out and basic 12-24V wiring knowledge; no vehicle-specific harness or mounting bracket is included.

Questions about this item

How do I install the Leelbox dual USB charger into my vehicle's 12V or 24V socket?

Insert each charger into a standard 12V-24V cigarette lighter socket; the built-in voltmeter powers on automatically to show battery voltage in real time.

What maintenance will the Leelbox charger need over time?

No scheduled maintenance is required; the ABS housing and smart chip protect against overheating and overcharging, so just keep the ports clear of debris.

What limits sustained charging speed when three devices are connected?

The shared 12V-24V input and internal protection circuitry regulate total output, so simultaneous fast charging on both QC 3.0 and PD 3.0 ports may reduce per-port current.
