5,000W surge, front-panel volt and amp meters, pre-wired remote port, and four AC outlets in a slim aluminum case — for RVs, work trucks, and off-grid systems.
The AIMS Power 2500 Watt 12V Modified Sine Inverter with Features (PWRINV250012W) converts 12V DC battery power into 120V / 60Hz AC electricity, delivering 2,500 watts continuous and 5,000 watts of surge capacity for tools, appliances, motors, and mobile equipment. Built on the same platform as the 1250W "with Features" model, this unit steps up to a higher output with front-panel volt and amp meters for real-time battery monitoring, a pre-wired remote on/off port, four AC outlets, and a thermally controlled cooling fan — all in a slim aluminum case with a pre-slotted mounting plate for permanent vehicle and off-grid installs.
More output, more outlets, and the monitoring tools you need to manage a full mobile power system — without a separate battery monitor or display.
Delivers 2,500 watts continuously at 20A AC output and 5,000 watts of surge capacity — enough headroom for the high startup draw of compressors, circular saws, refrigerators, and motors without tripping the unit.
A battery voltage meter shows your DC input level in real time, and an amperage meter shows the rate at which your battery is being drained — giving you live, actionable data to manage your system load without a separate monitor.
Four standard 120V Type 2 3-prong outlets let you power multiple devices simultaneously. Each outlet is rated up to 1,500W (UL recommendation) — use a power strip for additional connections when needed.
The built-in remote port accepts the optional AIMS Power remote on/off switch (sold separately), letting you power the inverter on or off from a remote location — ideal for units mounted in a compartment or under a seat.
90% efficiency at full load and 95% at one-third load means more of your battery's stored energy reaches your devices — minimizing waste heat and maximizing runtime from every charge cycle.
Over-temperature shutdown at 55°C (±5°C), overload protection, AC short-circuit protection, high input voltage protection at 17V, low-voltage alarm at 10.5V, and auto shutdown at 10V — with auto reset on most fault conditions.
At 14.5" x 6.5" x 3.0" and 10 lbs, this inverter is notably slim for its output class. The aluminum case dissipates heat more effectively than plastic housings, and the pre-slotted mounting plate makes it simple to secure the unit permanently in a truck bed box, RV compartment, van cabinet, or equipment enclosure without custom fabrication.

The amperage meter shows the current draw (in amps) at the DC input in real time — effectively telling you how quickly your battery bank is being drained under the current AC load. This helps you manage your total system load and avoid deep-discharging your batteries. Paired with the voltage meter, you have the two most important data points for battery health without a separate monitor: how much charge remains (voltage) and how fast you're using it (current).
At 2,500 watts continuous, you can run most standard household appliances and tools — a microwave, coffee maker, power drill, circular saw, sump pump, small refrigerator, or multiple smaller devices simultaneously across the four outlets. The 5,000-watt surge handles the brief high-current startup spike of motor-driven equipment like compressors, large power tools, and refrigerators. Always verify the running and startup wattage of your equipment before connecting, and do not exceed 1,500 watts on any single outlet (UL recommendation).
The inverter includes a pre-wired remote port that accepts the optional AIMS Power remote on/off switch (sold separately). Once connected, you can power the inverter on or off from a remote location such as a truck cab or control panel without accessing the unit itself. For units purchased before January 20, 2015, use the AIMS Power Remote On/Off Switch (PWRIREMPWR); for units purchased after that date, use the AIMS Power Flush Mount Remote (REMTOEHF). Check with TrueStead Supply to confirm the correct remote for your unit.
At full 2,500W load, DC current draw will be high — a single starting battery will not sustain this inverter under load. A dedicated deep-cycle battery bank is strongly recommended. For extended use, size the bank to your expected daily watt-hour load plus a safety margin. The inverter's low-voltage alarm (10.5V) and shutdown (10.0V) protect your battery from deep discharge, but a properly sized bank will give you meaningful runtime before those thresholds are reached.
This inverter produces a modified sine wave with phase correction — a stepped AC waveform designed to reduce the phase offset between voltage and current found in basic modified sine wave designs. It works well for most resistive loads, power tools, pumps, motors, and standard appliances. Some sensitive electronics — certain televisions, audio equipment, medical devices, and variable-speed drives — may still experience interference or reduced performance. If you need utility-quality power for sensitive equipment, consider AIMS Power's pure sine wave line.
Yes. This inverter works well in 12V solar setups where a charge controller maintains a battery bank and the inverter draws from that bank as needed. The volt and amp meters make it easier to manage solar charging vs. load draw in real time. The inverter does not include solar charging capability — a compatible charge controller and solar panels are required separately.
The "with Features" PWRINV250012W adds front-panel volt and amp meters, dedicated overload and over-temperature LED indicators, four AC outlets (vs. typically two on the base model), a pre-wired remote on/off port, and an aluminum case with a pre-slotted mounting plate. The base model is smaller and lighter; this model is the better choice when you want live system monitoring, more outlets, and remote switching capability in a permanent installation.
This inverter is covered by a 2-year parts and labor warranty and includes lifetime technical support from AIMS Power at no charge. Purchasing through TrueStead Supply as an authorized dealer ensures your warranty is fully supported by the manufacturer.
