Tundra ICM25245 45A Inverter Charger

The Tundra ICM25245 combines a modified sine wave inverter with an automatic battery charger in a single unit rated for 45 amps and 2500 watts continuous output. It is designed for truck operators and mobile technicians who need reliable 120V AC power from a 12V DC system while keeping starter batteries topped up.

Aluminium steel case with fan cooling

The charger section accepts 105 to 130V AC input and delivers a regulated 13.2 to 14.4V DC output, while the inverter runs from 10.5 to 15V DC and produces 120V AC. A built-in fan cools the aluminium and steel enclosure, and a five-foot link cable is included for connection between the modules. Ensure adequate airflow around the fan vents during extended high-load operation.

Check DC voltage range and AC input compatibility

Verify that your vehicle electrical system stays within the 10.5 to 15V DC window required by the inverter input. Confirm the shore-power or generator source falls between 105 and 130V AC for the charger to operate correctly. The separate inverter and charger dimensions differ, so measure the available mounting space against the stated heights, widths and depths before ordering.

Questions about this item

How do I confirm the charger is delivering the correct 13.2V to 14.4V output to my battery?

Connect a multimeter to the battery terminals while the unit runs on 105 to 130V AC input; the reading should fall within the 13.2V to 14.4V range and the cooling fan should be audible.

What cables come in the box and what must I supply myself?

A 5 ft link cable is included; you must provide the AC mains cord for the 105 to 130V input and the DC cables to connect the 10.5 to 15V inverter input to your battery bank.

Should I choose the 2500W modified-sine inverter or a higher peak-power version?

This model delivers 2500W continuous with a 5000W peak; select it if your 120V AC loads stay under 2500W and modified-sine output is acceptable for your truck appliances.
