Review on 8000W Split Inverter Charger Function Tools & Equipment for Jump Starters, Battery Chargers & Portable Power by Matthew Frandsen

The device works properly and definitely not as described in the manual. The photos and explanations inside are very different from the equipment I received. The phone number in administration was disabled and they didn't answer her email. They eventually responded to an email sent through Revain, but no knowledgeable people were there to help. I had to buy a separate meter to find out what frequency it's emitting as the frequency setting didn't work as advertised. Finally figured out and tested all the features without any help from the seller. You'd better be good at electronics and have tools and gauges if you're buying this because you're on your own.
