Solar generators have plenty of advantages, but they also have one major downside. They’re very expensive. Jackory, which makes a range of high capacity solar generators, is offering up to $1,080 off some of its products this Black Friday — so now may be an ideal time to grab one.

The deals are:

Jackery Solar Generator 2000 Pro is the pick of the bunch. It comes with one 200W solar panel, though versions with more panels are also available, and you can always purchase additional panels later. It’s 2,160 Wh capacity means you can run several appliances off it when fully charged. And there’s a staggering $1080 off the MSRP.

Black Series Campers has also partnered up with Jackery to give away a quarter of a million dollars worth of prizes. Anyone who picks up a Black Friday Deal from the company gets a free entry into the prize draw. You can watch the prizes being given away live on Jackery’s website, Facebook Page, and YouTube Channel. The live giveaway is set to take place at 2:30 p.m. PST on November 28, the same day Jackery’s sale ends.
