BMK 300W Car Power Inverter 12V to 110V with USB PD

The BMK 300W Car Power Inverter converts a vehicle's 12V DC into two independent 110V AC outlets plus four fast USB ports, giving reliable on-the-go power for laptops, CPAPs, and charging multiple devices.

Whether you're commuting, camping, or on a long road trip, the BMK 300W inverter turns your car's cigarette lighter or battery feed into a compact, stackable power hub. Built with shock-resistant ABS-PC housing and a clear LCD that displays input and output voltages, this unit helps you monitor battery health while delivering stable AC and rapid USB charging. It supports higher-draw devices than typical phone chargers and keeps your essentials charged simultaneously.

How does this inverter keep my laptop and small appliances powered?

The BMK 300W inverter provides two 110V AC outlets that deliver up to 300 watts of continuous power, suitable for many laptops, small kitchen appliances, and personal-care devices. Each AC socket has an independent on/off switch so you can run devices only when needed, reducing unnecessary battery drain.

• Dual 110V AC outlets deliver combined continuous output up to 300W.
• Independent switches let you control each outlet separately to save battery.
• Surge protection and stable output help prevent spikes to connected devices.

What fast-charging options are built in for phones and tablets?

This inverter includes four USB ports: two USB-C with Power Delivery up to 36W and two USB-A ports with Quick Charge 3.0. That configuration lets you charge a modern MacBook or iPad via PD while simultaneously topping up smartphones and accessories at high speed.

• Two USB-C PD 36W ports for rapid charging of PD-enabled laptops and tablets.
• Two USB-A QC3.0 ports for faster charging of phones and older devices.
• Multiple ports support simultaneous charging without significant slowdowns.

How does the LCD voltage monitor help during trips?

The inverter's digital LCD gives real-time readouts of input and output voltages so you can watch vehicle battery status and connected load at a glance. That visibility helps you avoid over-discharging the vehicle battery and lets you verify the inverter is delivering the expected output.

• Clear LCD shows input voltage from the vehicle and output voltage to devices.
• Readouts let you spot abnormal drops or spikes before they become problems.
• Useful when running power-hungry devices or during long idle periods.

Is this inverter durable and easy to fit in a vehicle?

The BMK inverter has a compact, stackable design made from shockproof ABS-PC material to withstand movement and jostling in a car or camper. Its low-profile footprint fits most center consoles, glove boxes, or cargo areas and is designed with ventilation to prevent overheating during extended use.

• Shock-resistant ABS-PC casing for road-ready durability.
• Stackable, space-saving shape for tidy vehicle storage.
• Ventilation and thermal safeguards help manage heat during use.

Who is this for? The BMK 300W Car Power Inverter is aimed at drivers and travelers who need reliable AC outlets and fast USB charging away from the grid: road-trippers powering laptops and small appliances, remote workers needing consistent power in vehicles, and anyone who wants to run CPAPs, mini-fridges, or charge multiple devices on the go. It is not designed to run large household appliances that exceed the 300W continuous rating. For safe operation, match your device wattage to the inverter's output, keep the unit ventilated, and monitor the LCD while using higher-load equipment.
