Whether you find yourself in a power outage because of a storm or you're preparing to go off-grid, a portable power station is always a smart buy. These units can be charged and recharged to help keep you online and powered up when electricity is nowhere to be found, and they're particularly useful during the warmer months when storms come raging through and kill the power. We've found one that's well worth investing in as it's on sale right now.

As of May 20, get the Jackery Explorer 500 v2 for $339 at Amazon, down from its usual price of $449. That's $110 off and a discount of 24%.

This power station has a 512Wh capacity with 500W rated power and 1000W surge power, all with 2 AC sine wave outlets to help you stay charged up and ready to go, no matter the situation. It can handle charging laptops, cameras, phones, small appliances, and more, so it's perfect for a camping trip, a night without electricity, or living off the grid.

It weighs just 14 lbs, and has a lightweight, streamlined design with a foldable handle. There's also an LED light on the unit itself, so you can see what you're doing even in the inky black darkness.

With a LiFePO4 battery that features 6000 charge cycles, this power station can reliably give you over 10 years of performance, with just 5% battery drain during half a year of storage. And it charges from 0 to 80% in under an hour, so there's less waiting around for it to be ready.

Now that it's on sale, it'd be a smart idea to grab one before the summer storms fully roll in and take over. It's never fun to be sitting in the dark, after all.
