We’re big fans of solar generators around here, and one of the best new models is on-sale for its lowest price ever (by far) right now at Amazon for Black Friday. The EF EcoFlow Portable Power Station Delta 2 retails (and often sells for $969). We’ve seen it go on one-day sale for as low as $479, but right now it’s just $399 with free shipping if you have Prime. This is a great deal on a pricy, but essential item for keeping your smart home running during an emergency or power outage.

You don’t always have a ton of time to charge your solar generator, but this beast can charge from zero to 80 percent in just 50 minutes. It can get to 100 percent in just 80 minutes. If you’re trying to charge on-the-go or quickly prep for an incoming storm, that time can be very valuable. Once the battery is charged, there’s enough juice in this unit to charge a smartphone nearly 90 times or a laptop up to 16 times. I’ve used it on many occasions to keep my internet router up and running during a power outage. It weighs just 27 pounds and fits in the trunk–or even the backseat–of a car with ease. You will always be happy to have this thing around.
