This little heating pad is so perfect for me. Although smaller than my home heating pad, it is the perfect size to use in the truck seat. It fits side to side without bunching up. It heats up very quickly and the hwat level is good. I have fibromyalgia and previously travel was so painful having to go for hours without relief. Using this heating pad for travel has allowed me to travel for hours without having to use excessive pain meds.I have recommended it to my FM group

Regardless the fact there isn't a L,M,H setting it is warm enough to do the job.Pluggs in gets warm within a few minutes. I tried a sunbeam with a USB plug in didn't get warm at all.

Have lower back pain. 2400 miles of travel. It worked great! Plenty hot and comfortable.

We use this in the car for my husband, who was diagnosed with pancreatic cancer. It works great to ease his back pain.

Excellent for car price works great they need to make one larger n longer n I’d buy

It keeps my back from hurting driving bus.

Works great, good price

This is exactly what I was looking for. My truck is older and didn’t come with heated seats. This heats up quickly and maintains a comfortable temperature. It was a bonus to discover it is on a timer!

Makes me feel like I have some luxury in my car haha

Recently went through rotator cuff surgery and localized heat therapy is now part of the 6-month recovery plan. I tried a USB rechargeable 5.3 volt battery-powered pad, but it just didn't get warm enough. This 12V unit delivers, even over a cotton shirt. And it is very comforting! What about home use? So, there are many inexpensive 110VAC - 12VDC converters available on Amazon with a power port (aka: cigarette lighter) socket at one end and an AC plug at the other. Simply connect the Trillium Car Cozy and then plug it into a wall socket. Been using it this way for about three weeks now and no problems at all.
