Snow and ice can cause plenty of headaches during winter, but losing power for a few hours might be the most frustrating. Suddenly, you’re trying to find a flashlight, keep your phone charged, and figure out how long the electricity will be out. A portable power station won’t keep the whole house running, but it can handle smaller electronics and provide some light until things get back to normal. It’s also worth having around for camping, tailgating, or working on projects in the backyard or garage when there’s no convenient outlet nearby.

Right now for a limited time, the BailiBatt 300W Portable Power Station is on sale at Walmart for just $100. That’s $70 off a compact backup battery with 266Wh of capacity and 300 watts of continuous output. It has a standard 110V AC outlet, two USB-A ports, two USB-C ports, and DC connections for charging various electronics. The AC outlet also uses a pure sine wave inverter, making it suitable for sensitive devices like laptops and other electronics, provided they stay within the power limits. Weighing just 6.5 pounds, it’s small enough to take on a weekend trip or keep tucked away for emergencies.

You can recharge the battery from a household outlet, your vehicle, or a compatible solar panel, although the panel is sold separately. A full recharge takes as little as two hours, and the built-in LCD screen lets you check the remaining battery level and power usage. There’s also an LED flashlight with several modes, including an SOS setting for emergencies. The 266Wh battery is better suited for phones, laptops, lights, and other smaller devices than running a heater or large appliance, but for $100, it’s an affordable way to have some backup electricity ready before the next winter storm.

“Definitely a powerful little power station,” said one happy buyer. “It’s a great value for the money in comparison to other big name brands, and it’s absolutely perfect for the off-grid lifestyle.”

Another user said, “I wanted something small to have for emergencies, and this fits the bill.”
