Qidoe GSG2018TV-7 QC 3.0 Charger

The Qidoe GSG2018TV-7 is a dual-port USB charger built for 12V and 24V vehicle systems. It fits a standard cigarette lighter socket and delivers Quick Charge 3.0 on both ports. A blue LED indicates power status. The unit is rated IP66 waterproof and includes short-circuit protection.

Vehicle owners needing fast USB charging

Drivers of cars, boats, RVs, motorcycles, ATVs or golf carts can charge two QC 3.0 devices at once. The 120W at 12V or 150W at 24V socket capacity supports accessories such as dashcams or GPS units. Buyers who need a USB-C Power Delivery port or a built-in voltmeter should look at other models.

Dual QC 3.0 ports with 18W per port

Each USB-A port supplies up to 18W through Qualcomm Quick Charge 3.0, with backward compatibility to QC 2.0 and 1.0. The smart IC detects connected devices and splits current automatically. This single spec decides if the charger matches your phone or tablet requirements.
