First, let me say I was going to buy the 1800w inverter test and review because power goes out a lot here, and we are older, so we needed something for a backup. This company offered the 1800 inverter to me for review, but I made it clear I was going to give an honest review to help people like us that don't have a lot of money but can't be in the dark. So with that said. First, the 100 w solar panel. THE NEGATIVE. 1 thing i saw was the American flag, as far as I know, not made at all in America, so you can check for yourself. It might just mean they sell to America. However, so far, these people have been really nice, and I told them I was going to be honest and they were fine with that. 2nd The solar panel could be a little hard if windy and you are handicapped to pop right up , but way dorable. Customer service response time was great, but shipping was a little long, i think due to the shipping company not them, but still came fast. They have an app that operates the system with a few cool features, but I probably wouldn't use that much, but some people will. NOW POSITIVES. WOW, light weight, well made, simple to set up and even has kick stands or grommets for hanging and an attached pouch to keep the wires and all different type connectors they give you. I STRONGLY think this is a great buy, and if i get the money, i will buy more to add on to charge faster. The INVERTER 1800w is AMAZING. Lightweight but rugged. Easy to read board 4 yes 4 plugs that can handle a LOT and can operate several things and charge things at once, including usb ports and more. The app is very simple but could be very helpful and connected very easily. It is just wonderful and very simple to operate. You can also charge it from an outlet, and it is safe for electronics. I dont give 5 stars easily but this super seeds it. I have seen other units but for the money so far I'm sold. It's AWESOME, which definitely makes us feel safer. If i didn't think so, I would say it. I'm gonna start testing the inverter, but if it does everything this good as it is now, it's a no-brainer. I'm not a profeshional just an old guy who needs a good set-up. I think this is a GREAT buy and definitely will help.
