BESTEK's 400W car power inverter converts your vehicle's 12V DC into two 110V AC outlets plus PD 30W USB‑C and QC 3.0 USB‑A ports for reliable charging on the road.

Compact and travel-ready, this inverter fits into a standard 32‑pin cigarette lighter and supplies steady power for laptops, small appliances and fast mobile charging. It blends AC convenience with modern USB fast‑charging protocols while including onboard safeguards to protect devices from thermal, voltage and short circuit risks. ETL‑certified and backed by BESTEK support, it’s designed for drivers who need predictable power away from home.

How much power can this inverter actually supply?

The unit delivers a continuous 400W DC‑to‑AC output through two 110V sockets, suitable for medium‑draw electronics and small household items used in vehicles. Peak and startup draws for some devices may exceed the continuous rating, so match your device's running wattage to the inverter's capacity.

• Continuous AC output: 400W total across both 110V outlets
• Recommended for laptops, DVD players, small pumps and warmers (typically 300–400W)
• USB ports handle mobile and tablet charging separately from AC load
• Not intended for heavy appliances like large hair dryers or high‑current heaters

What fast‑charging options does it offer for phones and laptops?

This BESTEK inverter integrates a 30W USB‑C Power Delivery port for laptops and fast‑charging phones plus a Quick Charge 3.0 USB‑A port for compatible devices. These ports let you charge modern devices quickly without occupying the AC outlets, making it efficient for multi‑device use.

Is it safe to use in my car for long trips and camping?

Safety features are built in to protect both the vehicle and connected electronics. A 40‑amp internal fuse plus thermal, over/under voltage and short‑circuit protections reduce risk during extended use. The inverter is ETL‑certified and BESTEK offers a 12‑month replacement warranty and 24/7 technical help.

• Thermal shutdown prevents overheating during heavy or prolonged use
• Overvoltage and undervoltage protection protect battery and devices

How portable and vehicle‑friendly is this inverter?

The inverter is roughly the size of a large smartphone, making it easy to store and carry for road trips or outdoor use. It plugs into most vehicles using the common 32‑pin cigarette lighter connection, so no hardwiring is necessary for routine charging needs.

• Compact form factor fits glove compartment or travel bag
