Jackery PowerPro, $480 with code POWER500

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 the Jackery PowerPro.

This electric “generator” features a 500Wh battery that can recharge a smartphone over 40 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, six hours connected to an AC outlet will do the job, or you can 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 $120 right now with promo code POWER500.
