This AIMS Power 2500W Power Inverter converts DC (direct current) power stored by batteries into AC (alternating current) electricity that can be used to run practically any small household appliances or tools. This produces a modified sine wave, which is capable of running most tools, pumps, motors and appliances. Use this product for off-grid back-up power at home, cabin, boat, solar systems or anywhere that doesn't have city power. This is a European UK model. Will not work with 120V US power. What really makes this 2500W AIMS Power inverter special is its capability to run off of most vehicle's and/or RVs'/boats' standard power systems at 12V or 24V. That makes the modified sine wave inverter very attractive to mobile business owners since users don't have to modify a vehicle's standard power system in order to run the inverter off of a car or truck. This definitely saves some money if upgrading a fleet of vehicles with some aftermarket equipment that requires this much power. Some of the popular mobile business applications include powering a small mobile office or kitchen, running tools on a work truck or construction vehicle, or supplying electricity to lawn maintenance equipment. The biggest incentives for business owners to use inverters for electricity include the fact that they make little-to-no noise, making for a more peaceful environment for customers, and that they're non-polluting, which makes for a great green-energy marketing campaign.
