Anker’s portable backup battery is nearly half off

Winter storms across the country are bringing heavy snow, rain, and — in some cases, as this Californian who briefly lost power a few days ago can attest — outages. If you want to prepare, Anker’s 521 PowerHouse can help keep your essential devices running and it’s on sale for $129.99 ($120 off) at Amazon. That is about $2 shy of its all-time low price and the best price we’ve seen since Black Friday.

What’s impressive about the 256Wh power station is the range of devices it can handle. You can charge smaller electronics like phones, tablets, cameras, and laptops multiple times using its two USB-A ports and single USB-C port, but it also features two AC outlets and a car socket. That means it can power low-wattage appliances such as a mini fridge, portable fan or heater (on low), electric blanket, and other gear that draws up to 300 watts. You don’t need to worry it’ll die, either — Anker says the battery is designed to last up to 10 years and offers a five-year warranty.

There are a few thoughtful extras, too. Small and weighing about eight pounds — roughly the same as a gallon of water — it’s relatively easy to carry thanks to its integrated handle. Anker also includes a built-in display for checking remaining battery life at a glance, along with a car charging cable. And if you’re outdoors or dealing with an extended outage, you can even recharge it using compatible solar panels — though you’ll need to buy those separately.
