Portable Cloth Heaters, Clothes Heating Pad with 5pcs Heating, USB Electric Heated Pad Adjustable Temperature Warmer for Outdoor Winter Clothes Seat Pet Dogs and Cats Warmer

Had these for over a year. Originally I just used painters tape and stuck them in my jacket. It worked great. IMO, use a tight fitting jacket or vest to keep the heat in. I treat this more like thermal underwear. Even at the lowest setting will make a big difference.At the lowest setting a modern cell phone battery will last for hours.Think of the heat output like those disposable hand warmers.

Not worth the money. It didn’t work!

Not a bs reviewmy step dad and brother in law work in a warehouse and outside in East Chicago. This and a 48,000mAh rechargeable battery pack for charging phones make this this AMAZING!!! Not gonna lie, the first heat setting is either way the Hi heat setting is more like Hell heat.But it if you're really looking for something like this

Drain batteries,

The red high temp setting only seemed to peak around 113 on all the pads. Seems that is usually the low setting for most vests.Even for how cheap they are it's probably not worth it if you're looking for a a lot of heat.

I got these as stocking stuffers for my niece. She works for Chick Fil A outside in the drive thru lines. They make them stay out there in all kinds of weather and they aren't allowed to wear jackets that aren't on brand. I got her these heating pads and one of those external battery for cell phones to use for a power source. She's been using these for a month or so and says they work really well. They are helpful on cold or rainy days. Her biggest complaint is about the wires, but I think that's a her thing - I can think of several ways she could get control of the wires.

Very versatile

Just got the mini heating pads. High, Medium and low works. You can feel the heat. Thinking about putting these in a cardigan or something like. Since can not have plug in heater at work. I purchased a power bank for cell phone and together its totally portable.. Great for if you have something in the winter season outside..
