Purchased this unit to act as partial backup to home using the EF 400W portable panels. The initial base line testing has been completed and the unit performed well. Will have final verdict after a few more weekend tests. The solar panels seem well built. The dual purpose kickstand is a little tough to use and does not show good value unless conditions are ideal (which is almost never the case)
I have not had a chance to thoroughly test it, I plan i doing it later this spring, but so far so good. Charging from an outlet is quick. The app and the controls are easy to use and the power output on some devices I have tried is excellent. It is a little heavier than I anticipated. but the handle and wheels make it pretty easy to move around.
Thumbs up--If grid goes down Earth quake(Calif) or electrical grid terrorist need something big/strong 400W panel to get Max out of Calif sun to preserve refrig contents
I know this unit charges fast..My main reason for purchase is to hold my refrigerator at temp during a power outage and there are many in my area. I have yet to see how it hold up. I own another brand that hold well, but the downside is that it take HOURS to recharge like 6-10 hours. Hoping this brand does all it promises.
