SunbeamUSB-C Heating Pad - Portable Pain Relief On The Go for Cramps Back Shoulder Arm & Leg Pain 12.5 x 7.5 Grey

I was looking for the previous model of this one but it's discontinued. The inside of this one is soft and comfortable on my skin, it does exactly what it's ment to do and if plugged in to the wall or even my computer, it stays warm for as long as I want it to. I wish it was soft on all sides and the strap was softer.

I think it is comfortable to wear and comes in handy for moving around the house. I do wish the actual heating part was wider, but it is still a nice additional heating pad.

I have muscle problems so I'm a heating pad power user and have purchased many great heating pads through Amazon. This was my first attempt at battery powered. For this product it was very frustrating trying to find a battery pak that would have the 2A AND fit into the pocket for it. I tried repeatedly on Amazon as did my husband using the terms specified in the instructions but no luck. When we finally found it, reviews were terrible. So to be able to use it out of the box, you would have to buy the version of this that includes the battery bank--which cost 2X as much-- or you have to buy other brands of battery and test to see if those will fit it the small pocket. None of our existing batteries fit & had 2A, which wasn't a deal killer b/c we were planning to replace those anyway. The battery pack from the other product--which matched the size of 2A battery paks we found on Amazon-- wouldn't fit into this one and the sizes of some of the packs we looked up on Amazon were iffy and we didn't have time to wait and test out packs. Luckily Amazon makes it easy to order and compare products. We had ordered 2 different battery heating pads at the same time to make a side-by-side comparison and b/c we didn't have time to shop around a lot. The two products were about the same price but the other one came w/battery pack and worked right out of the box. I really perferred the size and softness of this product but the battery frustration was a deal killer--we couldn't do a direct comparison w/out more ordering and waiting. I also liked that the other product came with a simple bag that everything could be stored in. I might have elected to pay the higher price for the version of this product that comes WITH a battery pack had I felt reviews were stronger than other similiar products. Having owned other products made by this brand name I've thought it was a good brand. They really degrade their brand name by doing this. That said, if I had ordered version of this product that came w/quality battery I might have kept it and sent back the lower priced competitor.

I love this. I leave one in the car for long road trips and one at my desk

Overall, I’d buy it again. The heat is ideal, and the size works well for a portable device, and power consumption is reasonable. That said, there’s a number of issues that really need to be improved upon.Note that the elastic strap is critical for proper heat delivery - these little pads just don’t have the power density you get out of something wired so pressure helps make up the difference. I find the pad to be less useful without it. Unfortunately, this is one of the problems - the strap isn’t strong enough to adequately hold the pad up on certain parts of the body when used with a battery pack. An ace bandage can mitigate this.The major issues lie with the power cord. The strain relief is inadequate and eventually your unit will fail when the stranded cable inside fails and tears apart. It’s also about 2-3 inches too short for easy use with power banks, requiring the use of the comically long extension cord ti make up the difference. I eventually modified mine to lengthen the cord, this can be done with a soldering iron and the included extension cord, and this adds a star to the product easily.Still though, this product and a little extra thought have done wonders for my sciatica, so I’m glad it exists.

It's small, but powerful. It comes with a cord to plug it into the wall, but I haven't used it. My batter pack fits perfectly in the pouch! I only ever use it on the lowest setting (3 heat levels) and it gets plenty hot for my cramps. The elastic band is very stretchy, and it even fits my very large body. It's small enough though that if I'm going to stay seated, I just tuck it in the waistband of my pants. As someone who only occasionally uses a heating pad, I find it absolutely worth the purchase.I went with 4 stars because the small plugin cord is very stiff and seems cheaply made. Mine is good so far, but it wouldn't surprise me if that cord is a point of failure. And unfortunately without that cord, it would be useless.

It is a good purchase. It is not very expensive but work its function. I usually feel lower back cold in winter or strong AC room, it keeps my back warm in the office when I sit in front of my computer, there are three temperature you can adjust, the lowest one is enough for me. Love it!

I like that is small, portable and hot. Obviously anything that produces heat on battery is going to take a lot of battery. Over all it works well
