And somehow, the universe always seems to put one person from each of these two groups into relationships, dooming them to fight over the temperatures in their shared vehicles forever!If you and your significant other — or heck, you and your kids or even you and the coworker you carpool with — can't get on the same page when it comes to your car's temperature, investing in a vehicle with dual-zone climate control is one potential solution. But if that isn't in the budget, we recommend simply purchasing the Wiher Rechargeable Car Fan instead. It normally retails for $50 at Walmart, but the best-selling fan is currently on sale for only $25, which should make buying it a no-brainer regardless of whether you're the "hot one" or "cold one" in your relationship.Wiher Rechargeable Car Fan, $25 (was $50) at WalmartWiher Rechargeable Car Fan, $25 (was $50) at WalmartCheck PriceThis fan is equipped with a vacuum suction cup, allowing you to stick it almost anywhere in your car, including on your dashboard, windshield, or side windows. It also features a fan head that you can rotate 360 degrees, enabling you to point it in any direction you want. Its built-in 3000mAh battery is a huge plus as well, since it helps you avoid running cords all over the place to run the fan while providing it with up to 10 hours of power.AdvertisementAdvertisementBut obviously, the best part about this fan, especially if you're the human furnace in your relationship, is that it blows a steady stream of cool air and keeps it circulating throughout your vehicle. It boasts three settings — gentle, natural, and powerful breeze — letting you choose the one that you and your cold-blooded partner can (hopefully!) agree on. It's also remarkably quiet, operating at below 40 decibels on even the highest setting.Related: Walmart's Bestselling Portable Air Conditioner Is Almost 40% Off, and It Provides a 'Refreshing Blast of Cool Air'"It's small but powerful," one reviewer wrote.
