Energizer 4000 Watts Power Inverter Modified Sine Wave Car Inverter

View on Amazon

I was looking for a powerful inverter to run various appliances and tools in my garden shed. I decided on the Energizer 4000 watt inverter for a few reasons. First, it has regular AC outlets that can handle higher currents, which is important for some power tools. Second, it comes with a generous two-year warranty, and by registering the product and leaving a review (like this one!), Energizer extends that warranty to three years – that extra peace of mind is always nice.

The Energizer inverter arrived well-packaged and with clear instructions that were easy to follow. Setting it up was a breeze. I’m using it with a couple of deep cycle RV batteries that are charged by solar panels, and it works perfectly for powering all my shed needs. If you’re looking for a reliable and powerful inverter with a long warranty, this Energizer model is a great option! Read more…
