S Series – 12-Volt Power Inverters – 300 to 1200 watts

100% Usable Watts
What we advertise is what we deliver. When you buy a Tundra product that claims to generate 2,000 W, you get a full 2,000 W of power. The only thing you have to worry about is feeding your inverter the proper input.

Genuine Tundra Reliability
Our success is based on several factors. One of them is our exceptional reliability. Every effort has been made to create the world’s best power inverter – and the most durable. It’s no surprise then that over 50% of all the inverters we’ve sold in the past 10 years are still in service.

The “Coldest” Power Inverters
The exceptional efficiency of our inverters minimizes heat generation and makes them run much cooler than any other in their category. The use of thermostatic fans that operate only when needed testifies to the superior efficiency of our design. As a result, problems related to overheating are now a thing of the past.
