Incredi-Heat - USB Heating Pad by Cabeau - Infrared Heat Therapy to Ease Muscle Strain, Relieve Pain, and Provide Targeted Compressed Heat - Compact, for On-The-Go Use

This is an amazing heating pad. I have back pain and can put it behind me in the car and plug into the usb port. Couldnt be easier. Love this pad! Perfect size for taking with you.

I think the concept was good, execution not so much. I wanted a heating pad for travel, to use in a car and on planes. The cord is not long enough. The pad doesn’t get warm enough. It is dual voltage. I get more warmth and pain relief from Thermacare pads. So much for trying to be more sustainable. I know there are limits to how much a USB powered device can actually heat up. I love my two digital heating pads I bought from Amazon, two sizes. Pure Enrichment PureRelief. King & XXL. One is a rectangle, the other a square. Various settings. The best, but would appreciate a dual voltage version of the XL.

I haven't used this on the road yet. I just attached this to my lumbar support cushion and plugged it in to this adapter that plugs into my car's cigarette lighter on one end and has a USB port at the other end and was very happy to see that the unit turns off when I turn off the ignition to the car. So I'm sure this will be great on long car rides even though the lumbar support cushion by itself has been very comfy.

This item is a little pricey for what it does. It doesn’t get very hot and I wish the power cord was longer. My intent was to use this in my golf cart while playing golf to keep my back from getting stiff. Hasn’t been especially helpful.

So far I have used this with my portable 10k battery pack and it works awesome. Heats quickly. I plan to use on a long flight so looking forward to the convenience of small size. Great product.

Used it for travel. Though it's a bit too small, it offered the convenience of USB charging, so I made do. Too bad it quit after 6 or 7 trips.

I loved the idea of a heating pad that used a usb cord! It could have been perfect for over seas travel, not having to mess with converters or adapters. That is what I got it for, but it has a flawed design. The cord is too short to reach from an outlet. If I plugged it in at a desk, I had to set right there by the plug. If I plugged it in by the bed it wouldn’t reach.I liked the idea of the smaller than normal size, but didn’t realize only the center would heat, not edge to edge.Like I said, I really wanted this to work but I was sorely disappointed. I will keep it and try it in the car and see if the cord is long enough.

Bought this for my wife for sore muscles and was totally disappointed. While it is easy to work and can go anywhere, it does not get hot at all. It barely gets warm and provides no relief to sore muscles. Tried the three different heat settings and could not find any discernable different in temperature between them.I tried to return, but was after return period, so am stuck with something that does not work.
