HiGropcoreHiGropcore Portable Heated Seat Cushion, 【No Power Bank】 USB-Powered Heating Cushion Back Chair Pad for Camping Chair, 3 Mode Adjustable Warm Seat Cushion for Outdoor, Camping, Fishing, Hunting

To be honest, I didn't get this for a camping chair. Instead, I got it to use with my desk chair as I work from home. My basement office can get quite chilly during the winter months so I thought that this heated cushion could help keep me warm. While the cushion did generate a decent amount of heat, it didn't fit well on my desk chair and was quite uncomfortable. However, I don't blame the cushion for this as it wasn't specifically designed for my chair. I then tried it on a camping chair and it was much better. My wife has since confiscated this cushion to keep warm by the fire on cold nights. Overall, the cushion works well as long as it is used in a chair that it fits properly.

There’s not a whole lot of cushion to those things and I had to get my own batteries for it

This cushion is firm, but comfortable to sit on; the fabric on the upper side is soft and pleasant to touch. It's very lightweight, yet seems reasonably sturdy. The heating works quite well! Using it indoors, it's very warm even at its lowest level - I suspect it would do quite well outdoors in proper cold as well.Things to consider? Well, the button is on the upper face of the cushion toward the right back side of the seat. Depending on how you're sitting/how much you move/how large of a person is sitting there, it is entirely possible to change the heat setting with your bodyweight - but careful positioning would probably fix that if it happened.It also didn't like the first battery pack I used (for a heated vest) and was a bit finicky (losing settings, turning off, etc.), but swapping out to a standard generic USB battery pack made it work perfectly - so just make sure you give it the kind of power it prefers.

The item is fairly nice, it's got a pleasant fabric feel on the side that you sit on. It does take a while to warm up and it would be nice if the heating element covered more, but it is sufficient for what it does. After 4 hours of usage it only used about 25% of my power bank, just slightly less than it would take for my Samsung Galaxy to charge from 0 to full.

This heated seat pad is a life saver in very specific situations. It's not very wide or particularly comfortable, but it gets very warm, and has a good selection of settings to keep you toasty warm. The design is made to fit things like camp chairs, but it would be equally useful for stadium seating or even a curb during a parade. I've tried using it indoors, and it doesn't fit well on my office chair (it's too thin), and I actually find the heat to be too much.As noted in the listing, it doesn't come with a battery pack, but will plug into any USB power bank. I recommend a minimum size of 5000 mah to ensure you have enough power to last a few hours, and even to bring a backup power bank if you know you'll need it for hours. It has straps so you can strap it to a chair, but as noted, it's very thin, and the straps aren't long enough to go all the way around wider chairs.Best Features- Heats up fast and gets very hot- Very light and portableThe ConsIt's only about 18 inches wide, so for most people, this won't cover the full width of their body in all places.
