If you get cold easily or work in a chilly office, the Dreo space heater is 10% off and includes a remote. It’s small enough (3.04 pounds) to take to work or carry from room to room but has a 1500W advanced PTC system that can deliver heat up to 200% farther than a traditional space heater.

It also has a 12-hour timer, child lock, and memory function, so you can stay comfy no matter where you are. Plus, the tilt-detection safety system and V0 flame-retardant materials make it a safer heating option.

Right now, you can get the Anker 535 PowerHouse for $329.99 — that’s $170 off and a nice deal if you're looking for a backup power solution to keep your devices charged and running during an outage. The Anker 535 is also a Mashable favorite that we’ve recommended in the past for its powerful 1,024Wh battery capacity, multiple ports, and fast 60W USB-C charging.

“At $500, I can say that it is worth the investment for somebody who needs to be prepared for inclement weather (like myself living in Florida) or spends lots of time in remote areas and may not have access to outlets such as campers or those on a road trip,” writes Mashable contributor Jenna Clark.
