TrueRated Power™ TrueRated Power is Wagan Tech’s coined term for truth in advertising and performance. While actual output wattage of competitor’s inverters varies greatly, Wagan Tech inverters help consumers to understand and trust that the number printed on the inverter is the actual output of the device. Nearly all of Wagan Tech’s Inverters feature TrueRated Power. Simply put, our inverters are tested at full load and will sustain that load continuously for 24 hours at the wattage printed on the inverter. For example, our Elite 400 Watt Pro 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 competitor’s 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!). Wagan Tech builds our inverters with high peak surges that allow up to 3x the continuous rating to support high surging appliances such as tools, microwaves, air conditioners and refrigerators. Wagan Tech uses top quality components and reliable MOSFET transistors – the key factor in reliable inverter manufacturing. When you are looking for an Inverter that supplies the wattage that you need and is reliable while cost effective, look no further than Wagan Tech's Inverters; supplying you with TrueRated power!
