The AIMS Power PWRINV400W is a compact 12V DC to 120V AC modified sine wave power inverter rated for 400 watts of continuous output and 800 watts of peak surge, making it a practical option for vehicles, RVs, work trucks, boats, and small off-grid battery setups. It connects to a standard 12V battery source using the included cigarette lighter connection and cable, with no vehicle modifications required for typical use within the rated load. Dual three-prong AC receptacles let you plug in two compatible devices at once, and front-panel LED indicators give a clear read on power status and fault conditions at a glance. Built-in protections cover overload, over-temperature, short circuit, high input voltage, and low voltage shutdown, helping to protect both the inverter and your battery source during operation. At just 2 pounds and 7" x 5" x 2.13", it fits easily in a vehicle, van, or storage compartment, and AIMS Power backs it with a 2-year parts and labor warranty.
This AIMS Power inverter is designed to convert a 12V battery source into 120V AC output for compatible devices. It is suitable for vehicle, RV, marine, work-truck, and small off-grid battery applications where compact AC power is needed without a generator or shore power connection.
The PWRINV400W provides 400 watts of continuous power and 800 watts of peak surge capability to help handle the brief startup draw of motors, pumps, and tools that spike above their running wattage. Always confirm your device's continuous and startup wattage requirements against the inverter's rated output before connecting equipment.
This inverter produces a modified sine wave at 120V AC and 60Hz, compatible with many small tools, battery chargers, fans, pumps, and general electronics. Some devices with sensitive power supplies or certain motor types may perform better with a pure sine wave inverter — AIMS Power offers pure sine wave options for those applications. Always verify your device's waveform requirements before use.
The inverter includes over-temperature protection, overload protection, AC output short circuit protection, high input voltage protection at 16V, and low input voltage shutdown at 10.6V. A low voltage alarm activates at 10.5V to warn of a dropping battery before shutdown occurs. The aluminum case and dual cooling fans assist with heat management, keeping the unit compact and practical for mobile or battery-based setups.
The AIMS Power PWRINV400W connects directly to a 12V battery and delivers 120V AC output through two standard three-prong receptacles. With 400 watts of continuous power and 800 watts of peak surge, it handles a practical range of small AC loads for vehicles, RVs, work trucks, and off-grid battery systems.
With modified sine wave output and built-in electrical protections, this inverter is a practical choice for many compatible small AC loads. Always confirm your device wattage, startup surge, and waveform compatibility before connecting equipment.
