Whether you’re planning off-grid camping trips or just want to be the only person on the block with a working fridge during a summer blackout, there's no doubt that having a reliable power station is a good investment.

As of Jan. 5, you can get the Jackery Explorer 1000 v2 for $398.99, down from $799, at Amazon. That's a 50% discount and $400.01 savings.

The v2 model features a 1,070Wh LiFePO4 battery, which is rated for 4,000 charge cycles. In plain English, that means you can use it daily for over a decade before the battery even starts to show its age. It’s also 18 percent smaller and lighter than the previous version, weighing in at just 23.8 pounds, so you won't throw out your back lugging it from the car to the campsite.

You'll also get a 1,500W AC output with a 3,000W surge peak (plenty of power to run a full-sized fridge, a coffee maker, or even a portable AC unit). If the battery does run dry, you can juice it back from 0 to 100 percent in just one hour using the "Emergency Super Charge" mode in the Jackery app.
