ECOFLOW Delta Max

 If you’re attempting off-grid living or need an extra-large capacity during an emergency for any reason, the ECOFLOW Delta Max is an excellent option. This battery has a large capacity of 2016 Wh, and you can link it with up to two more batteries if desired. That puts your total watt-hours at a whopping 6048! 

The ECOFLOW also boasts a rapid charge feature that will get you an 80% charge in about ninety minutes. Of course, the rapid charge feature works via an outlet or your car, not through solar panels, which charge much slower. 

That said, even with pure solar charging, this generator links to 800w panels and can fully recharge in three to six hours, which isn’t bad at all. Plus, it comes with an app to control and monitor everything remotely. You can turn off ports, view output, and more without ever leaving your couch.

The Delta Max isn’t exactly affordable, especially if you plan to connect two or three of them at once, and you’ll have to purchase the panels separately. It’s also fairly heavy, so if you hoped to use it while camping or in an R.V. as well as for home emergencies, it might not be the best bet. 

However, in the event of a multi-day power outage, it’s one of the best solar-powered generators on the market.
