Leelbox 36W Dual USB Car Charger

The Leelbox car charger delivers 36W total output through two USB ports, each rated at 18W and 3A. It supports QC 3.0 fast charging for compatible devices, allowing a phone to reach 80% in 30 minutes. A colourful voltmeter monitors battery voltage in real time, and an ON/Off switch cuts power without unplugging.

Drivers who want fast charging

This unit suits drivers who need to charge two phones or tablets quickly while keeping an eye on the vehicle battery. The built-in voltmeter and LED illumination help in low light. It is not for buyers who need more than two ports, higher per-port wattage, or USB-C Power Delivery.

Dual QC 3.0 ports with 36W total power

The defining specification is the dual QC 3.0 USB-A ports sharing a 36W budget, with each port capable of 18W output. Certified to UL, FCC, ROHS and EMC standards, the smart chip provides over-voltage, short-circuit and over-temperature protection for safe operation.

Questions about this item

Can I keep using my older phone that only charges at 5 V while the charger supplies up to 36 W total?

Yes — each QC 3.0 port delivers up to 18 W and negotiates the correct voltage with any connected device, so legacy 5 V phones charge safely alongside newer handsets.

What should I watch on the built-in voltmeter to know the charger is functioning properly?

The colorful voltmeter shows the car battery voltage in real time; a stable reading while both ports are in use confirms the charger is operating as intended.

Does the package include any charging cables, or must I provide my own?

Only the dual-USB charger adapter with its ON/OFF switch and voltmeter is supplied; USB cables for your devices are not included and must be purchased separately.
