3706 Smart AC 425W Power Inverter
Coming from a long lineage of powerful and reliable inverters, Wagan Tech is reviving the Smart AC line with the new Smart AC 425W Power Inverter!

As large power inverters became our primary focus (ProLine & Pure Line Inverters), we lost sight of the small and popular Smart AC series; well, not any more!
Like its predecessors, the new Smart AC 425W Inverter is powerful and affordable with the reliability that we are known for!

Front Component Details
On the front of the Smart AC 425W Power Inverter are two 120V AC outlets, a 2.1A USB Power Port, LED Indicator lights, and the Power Switch.

Rear Component Details
On the rear are the color-coded Positive Input Terminal, the Negative Input Terminal, and the Load/Temperature controlled cooling fan.

In your vehicle, boat, RV, Camper, tail-gating, camping, or anywhere you need to turn DC (battery) power into AC (household) power is where the Smart AC 425W Power Inverter will shine! 400 continuous watts means that you can run your appliance without worry of the Smart AC 425W Power Inverter letting you down like lesser inverters. A small blender, TV, gaming system, dorm refrigerator, and other household electronics are all able to be powered!**

TrueRated Power™
TrueRated Power is Wagan Tech’s coined term for truth in advertising and performance. Simply put, our TrueRated inverters are tested at full load (the number printed on the inverter) and will sustain that load continuously for 24 hours.
For example, our Pure Line 400 Watt Inverter will run for 24 hours straight with a 400 Watt load. Our competitors claim “continuous wattage” when in fact most are only rated at 20 minutes of continuous wattage. After 20 minutes, the competitors output wattage will drop down by as much as 25% of their claimed wattage (in a 400 watt inverter, that can be a 100 watt loss!).
