After a new round of testing, we’ve made the Jackery Explorer 1000 our top pick, the Anker PowerHouse II 800 our runner-up pick, and the Jackery Explorer 300 our budget pick.
If you’re going off the grid or prepping for an emergency, the Jackery Explorer 1000 can keep your electronic gear running for hours—or even days—at a time. It’s roughly the same size and weight as a small microwave, and it provides a steady stream of power without the noise or exhaust of a gas-powered portable generator.
After 73 hours spent testing 16 portable power stations, we found that the Explorer 1000’s impressive max output, wide array of ports, easy-to-use interface, and rugged exterior helped it stand out from the competition.
This unit packs lots of power into a portable, durable, easy-to-use package. Plus, it has more AC, USB-A, and USB-C ports than most portable power stations we’ve tested. *At the time of publishing, the price was $1,000. The Jackery Explorer 1000 is light enough for the average adult to lift and carry safely, yet it managed to run even the most power-hungry appliances in our tests.
It also had one of the highest battery capacities among the models we tested, suitable for keeping most devices, such as a laptop or CPAP machine, running all day (or all night) long.
We love its easy-to-read screen, which shows input/output wattage and how much power is left in reserve. Plus, it has more output ports—three AC, two USB-A, and two USB-C—than almost any portable power station we’ve tested, allowing you to charge a variety of gadgets ranging from laptops to cameras to GPS units.

Jackery Explorer 300
This model has a great capacity, good output, and plenty of port options. Plus, it weighs less than 20 pounds and costs less than other top contenders.
Anker Powerhouse II 800
May be out of stock. The Anker PowerHouse II 800 has a lower max output than our top pick, so it might not be able to power your highest-wattage appliances, such as a vacuum or window AC unit.
Jackery Explorer 1000
But its capacity is almost as good, and it’s a few pounds lighter. Like the Explorer 1000, it has a tough exterior, a highly portable design, an informative display, and output ports (two AC, four USB-A, and two USB-C) that provide plenty of charging options for a wide array of devices.
