A portable power station can be useful in plenty of situations from camping to a power outage. Some models focus on portability while others are durable enough to leave out in the rain. If your main concern during a power outage is keeping the refrigerator on, the Anker Solix S2000 might be the perfect model.

Anker Solix designed the S2000 specifically for home use during a power outage. The design with AC ports on both the front and back means its great for setting on the counter and plugging the fridge into the back while keeping the front open for a lamp, the coffee maker, and recharging small gadgets.

With 2,010Wh of battery capacity, Anker says it can keep a fridge running for up to 35 hours. In part, that's thanks to Anker's low 6W power draw. With an under 10 millisecond uninterrupted power supply, you can keep the refrigerator plugged into the Solix and the Solix plugged into the wall on grid power. If the power cuts out, the Solix will take over in under 10 milliseconds.

If you're not looking forward to the upcoming storm season since that means worrying about food spoiling in the fridge during an outage, upgrade to the Solix S2000. It can keep foods cooling for over 24 hours and it's on sale for under $650.
