BESTEK 148W Cigarette Lighter Splitter 9 in 1 Cigarette

BESTEK 148W Cigarette Lighter Splitter expands one vehicle socket into three powered sockets and six fast-charging ports, delivering up to 148W to run accessories and charge devices simultaneously.

Designed for drivers who need reliable power on the road, this 9-in-1 car adapter combines three cigarette lighter sockets with a mix of USB-C Power Delivery and USB-A ports (including QC3.0) so you can keep dash cams, tablets, laptops, phones and small 12V accessories running together. Built-in safety circuitry, an LED voltage monitor and a master power switch add control and protection for modern vehicles and accessories.

How many devices can it power at once and what are the outputs?

The BESTEK splitter supports powering or charging up to nine devices at the same time: three 12V cigarette lighter sockets plus six USB charging ports. It prioritizes safe distribution with intelligent chips that recognize connected devices and allocate current for optimal charging.

• Total peak output: up to 148W (single socket limited to 120W).
• USB outputs include 1×PD 30W, 1×PD 20W, 1×QC3.0 18W, and 3×standard USB ports (shared max 18W).
• Supports both 12V and 24V vehicle systems.

What safety and monitoring features are included?

This adapter integrates multiple protective circuits to guard devices and the vehicle battery from common electrical risks. An LED voltage display continuously reports battery voltage and will flash if readings fall outside safe ranges, offering early warning of battery issues.

• Protections: over-voltage, over-current, overheating, short-circuit and over-loading.
• LED display shows real-time voltage; flashes when voltage is too high/low.
• Master on/off switch lets you cut power to all outputs instantly.

Which devices and vehicles are compatible with this splitter?

The BESTEK 9-in-1 adapter works with a wide range of in-car electronics and most vehicle types, including cars, trucks, RVs and SUVs. It's suitable for powering dash cams, GPS units, portable refrigerators, humidifiers and charging phones, tablets, laptops or gaming devices while traveling.

• Single socket supports cigarette lighter functions up to 120W (check device draw).

How does charging speed and smart distribution work?

Smart charging chips inside each port automatically detect the connected device and provide the fastest safe current available. With PD 30W/PD 20W and QC3.0 18W ports, the unit can quickly top up compatible phones, tablets and some laptops while remaining efficient for smaller USB devices.

• PD 30W and PD 20W deliver fast USB-C charging for phones and tablets.
• QC3.0 port provides rapid charging for older quick-charge devices.
