It can feel miserable sometimes in the summer months to be outside for long periods of time, whether you're mowing the lawn, walking around a theme park, or having to tune up your car. Ever had the thought, "I wish I could have an air conditioner following me around in this heat?"Well, there are actually portable air conditioners that you can wear around wherever you go for whatever you’re doing this summer. According to Popular Mechanics, wearable air conditioners (also called portable neck fans) are battery-powered devices that rest around your neck and create a breeze that keeps you cool while traveling or spending long days outside. Most can last 10 hours on a single charge, and they are pretty affordable. It could be a worthwhile investment if your home is prone to getting hot and stuffy, or you live in an area that gets uncomfortably warm during the summer. We found some options and even highlight some recommendations from our partners at Popular Mechanics below. JISULIFE Portable Neck FanSocial media has been raving about this particular neck fan, and our partners at Popular Mechanics say the hype is real.

The fan has three speeds and provides as low as four working hours to 16 working hours, depending on the fan speed you are using. Popular Mechanics labeled this fan as their top pick but did mention that if you wanted to work out while wearing this neck fan, it might not be ideal.What’s even sweeter is that the JISULIFE Portable Neck Fan is on sale right now.

It has 78 air vents and three speeds, but one difference users point out is the low noise you get on regular speed, thanks to the multi-stage air duct design. One customer did note that the highest speed is a little loud, so that’s something to consider if you feel compelled to have the fan blasting at full strength. It’s also made up of a silicone material that makes it a bit more comfortable and skin-friendly. Oh, and this fan is also on sale right now, with customers able to take 20% off by clicking here. ICEBIRDS Portable Neck FanThis was Popular Mechanics’ top pick for kids. Our partners say the fan for kids comes in a size that works for small necks, and there are various fun designs that kids will love (our favorite was bear orange). The neck fan is bladeless, making it safer for kiddos, and it’s made up of silicone material to make it soft and elastic. It’s a great pick if you and your kids will be out in the hot sun for a long while during a trip to the theme park, or if they’re just reading a book at home in the summer and want to stay cool.
