Sunbeam® GoHeat USB-Powered Heating Pad

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

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 just received the heating pad. Turn it on and it works. The highest setting may be too hot.

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.

Super convenient to use, easy to carry when traveling. USB corded. Three heat levels. I put it in a cosmetic bag and take it with me when traveling - great after a day in the car or plane.

These are just OK. They're better than nothing, and they do fulfill the need to be portable for travel. I can take these to other countries with me, and I can power them from my own portable power bank.However, the power on these pads is fairly low; they do not generate as strong a heat as plug-in pads. In addition, the heating area is smaller than it looks. The heating element does not cover the portion of the pad with the pocket and on/off key, so it's a pretty small area that can barely reach front-and-back on a shoulder.The price isn't bad and it does come with its own USB plug. Do note that this pad (as indicated in the listing) does NOT come with a battery pack. It must be plugged in while in use.

Great for traveling, especially hiking trips. Easy suitcase fit. Works well plugged in. Doesn't work well on external battery pack. Mandatory shut off after 2 hours, but you can turn it right back on for more.
