Car charger with voltmeter and switch

The Leelbox 12 V 36 W car charger adds two Quick Charge 3.0 USB-A ports and one USB-C Power Delivery port to a vehicle’s 12 V socket. A built-in voltmeter displays the supply voltage while an integrated power switch cuts output without unplugging the unit. It is designed for cars, boats, motorcycles, golf carts, ATVs and RVs.

Suits drivers charging phones, tablets.

This charger suits drivers who need to fast-charge up to three mobile devices at once and want to monitor the vehicle’s voltage at a glance. Buyers who need to charge a laptop from the USB-C port should look elsewhere because the PD port does not support laptop charging.

Sustained multi-device charging

Under continuous load the charger delivers up to 36 W shared across the three ports while the voltmeter lets the driver watch for voltage drops that indicate a weak battery or alternator. The power switch isolates the output when the vehicle is parked, preventing parasitic drain during long stops.

Questions about this item

What voltage vehicle system does the 12 V car charger require?

The charger plugs into any 12 V socket in a car, boat, truck, motorcycle, golf cart, ATV or RV.

Will my older phone that only supports standard USB charging still work with the QC 3.0 and PD ports?

Yes, each port negotiates the highest speed the connected device accepts, so legacy devices charge at their normal rate.

How can I confirm the charger is delivering power once installed?

The built-in voltmeter displays the live vehicle voltage and the power switch lights up when the circuit is active.
