USB heated portable electric blanket

I want to buy a USB heated portable electric blanket to use while watching TV. Is it possible to run this via a mains adapter with USB ports or are these ports only for charging items with USB connectors? Thanks.

Depends on the adaptor you use. Most should work.

As I said on the other forum "I am sure it is, but USB is max around 2 amp, at 5 volt, so 10 watt, this is so little heat, only likely to work as a hand warmer." I was looking at a 4 x USB plug 4 x 13A connector block, and noted the whole 4 were only rated 2 amp, where a wall socket with USB each is normally rated at 2.1 amp, so does depend on the adaptor as already said.

Ok, thanks for that. I think then that I won't invest in one if they give so little heat.

But bear in mind just a blanket will help reduce your heating costs

You had a candle! ... Luxury!

My dad used to suck a mint and we'd sit round his tongue to get warm!

I have worked on a few houses that were fire damaged due to candles and some involved deaths. I would never light a candle in my house.

If you are going to plug it into the mains get a proper heated blanket, they will put out much more heat. You can also get heat pads that you lie on, or even just get a cheap electric blanket designed for a bed, lay on that and put a normal blanket over the top of you.

My partner does WFH a lot now and the flat is a bit chilly in the winter. Rather than put the heating on I bought a heating pad which we put on her office chair, she then puts a blanket over her shoulder and legs. Keeps her toasty warm and only draws 10W on low which is often enough but if its really cold it can go up to 45W on high.
