Buying Guide

Match input compatibility

Confirm the inverter accepts the battery or tool voltage you plan to use, such as Ryobi 18V, DeWalt 18V/20V, or a 12V car battery

Check AC and USB outputs

Choose a unit with the right mix of AC outlets and USB-A/USB-C ports to power your devices without extra adapters

Mind continuous wattage

Use the inverter's continuous watt rating (e.g., 200–300W) to ensure it can run your intended equipment without overload

Prioritize safety features

Look for overload, short-circuit, and thermal protection to prevent damage when used outdoors in garden or patio settings

Consider form factor and mounting

Smaller, lightweight inverters are easier to position in sheds, on carts, or in vehicles; check for screw mounts or flat bases
