ALLWEI 300W Car Power Inverter 12V to 110V — Blue, 2 AC Outlets + USB-C PD 27W

The ALLWEI 300W Car Power Inverter converts a vehicle’s 12V DC into two 110V AC outlets plus fast USB charging, giving you reliable power on the road.

Compact and built for travel, this blue ALLWEI inverter fits in a cup holder or glovebox while delivering up to 300 watts of continuous AC power. It includes two household-style AC sockets, a USB-C Power Delivery port (up to 27W), and a quick-charge USB-A port (up to 18W). Rugged aluminum housing, smart protection circuitry, and an automatic cooling fan help keep devices safe during longer runs or heavy loads.

What devices can I run from this inverter?

You can power low- to medium-draw appliances and electronics commonly used on trips: laptops, game consoles, small TVs, DVD players, and battery chargers. Keep in mind the combined AC output should not exceed the 300W continuous rating; for items over 180W, use the included battery clips for direct battery connection.

• Laptop charging and small monitor power
• Portable gaming consoles and streaming devices
• Small kitchen appliances under 300W (check the appliance’s running and surge power)
• Phone and tablet fast charging via USB-C/USB-A

How fast will my phone or tablet charge?

The inverter’s USB-C port supports Power Delivery up to 27W, while the USB-A port delivers up to 18W, allowing modern phones and tablets to charge quickly from your vehicle. The two USB ports share a combined maximum output, so charging multiple high-draw devices at once may split available power.

• USB-C PD up to 27W for fast charging compatible devices
• USB-A quick-charge up to 18W for older phones and accessories
• Total USB output capped to maintain safe operation
• AC outlets remain available for higher-power gadgets

Is the inverter safe and durable for repeated use?

Yes — ALLWEI designed this model with an aluminum alloy shell for impact resistance and improved heat dissipation. Built-in smart electronics monitor voltage and current, and the silent, temperature-controlled fan ramps up only as needed to keep temperatures in check.

• Aluminum housing resists wear and helps cool components
• Automatic cooling fan adjusts to ambient temperature
• Protection against overheat, over/under voltage, overload, and short circuit
• Includes cigarette lighter plug and battery-clips option for higher loads

How portable and user-friendly is this inverter for travel?

This inverter is about the size of a large smartphone (approx. 5.1 x 3.1 x 1.8 inches), making it easy to stow in a bag or vehicle compartment. Plug into the 12V cigarette-lighter socket for immediate use or switch to battery clips for devices that need more stable current when drawing higher power.

• Compact footprint fits glovebox, console, or backpack
• Quick-plug cigarette lighter adapter for instant power
• Battery clips included for devices over the lighter socket limit
• Simple interface: two AC outlets plus two USB ports

Who is this for? The ALLWEI 300W Car Power Inverter is aimed at commuters, road-trippers, van-lifers, and anyone who needs household-style AC and fast USB charging from a 12V vehicle socket. It’s ideal when you need to run small electronics away from a wall outlet—laptops, chargers, entertainment gear, and mobile office devices—while prioritizing a compact footprint and built-in safety. If you plan to operate appliances near the inverter’s power limit, use the included battery clips and check device surge requirements before use.
