If you want to power devices like TVs and mini-fridges while you’re out at a tailgate, your only real option until recently has been a noisy, gas-guzzling generator. But the proliferation of affordable lithium batteries and solar panels is threatening to change that, as evidenced by this Suaoki battery.

This electric “generator” features a 444 Wh battery that can recharge a smartphone dozens of times, a laptop 3-6 times, a TV for several hours, and a lot more. If it draws less than 300W, you can plug it in here.

When it comes time to recharge, you can charge it from any AC outlet, from your car’s power outlet, or go completely off the grid with solar panels (not included). It wouldn’t be ideal for weeklong camping trips or extended power outages at home, but it might be just enough power for a tailgate or barbecue, and you can save $92 right now with promo code 52J3KJGA.
