I received this machine for free and can keep it after the review. I get paid NOTHING from the company and EARN nothing if you buy it. If you're looking for a solar power box and need help picking one out, please send me an email to southernprepper1@yahoo.com and we can arrange a time to talk. Picking the best one for you to fit your budget and power needs. I purposely make sure I do not get paid anything from the power box company if I recommend their machine. I have no financial interest what one you buy. My goal is to get the best one for YOU.
