Two-pack 12V USB charger for 12-24V vehicles

The Leelbox 78W USB-C car charger comes as a two-pack, each unit fitting a standard 12V socket in cars, RVs, boats, motorcycles or trucks. Two 30W PD USB-C ports and one 18W Quick Charge 3.0 port charge three devices at once. A built-in button switch cuts power without unplugging the unit.

78W total output split across three ports

Each USB-C port delivers up to 30W PD 3.0 while the USB-A port supplies 18W Quick Charge 3.0. An iPhone 15 can reach 60 percent in 35 minutes with a USB-C to Lightning cable; compatible Android phones hit 80 percent in the same time. The 12V-24V input range limits use to vehicle electrical systems only.

Waterproof cover and smart-chip protection

A removable cover seals the ports against water and dust for marine or off-road use. Each port contains a smart chip that balances current so simultaneous charging does not reduce speed. The longer housing sits deeper in the socket, reducing vibration on rough terrain.

Questions about this item

Should I buy the 2-pack or a single unit?

The 2-pack gives you a spare charger for a second vehicle or travel bag and the supplier states each unit saves about 20%-30% compared to buying separately.

What does the 78W total mean when I plug in three devices?

Each USB-C port can deliver up to 30W PD 3.0 and the USB-A port up to 18W QC3.0 so three devices can fast-charge at the same time without slowing each other down.

How does the 12V-24V input work in my truck or boat?

The socket accepts any 12V-24V vehicle system and includes a removable waterproof cover for marine, RV, motorcycle or truck use.
