You are the person in the house who is cold when nobody else is. You have already bought something that was supposed to fix it. This was written for you.
The Reason Your Heated Blanket Never Felt Warm Is One Number.
Ten watts. That is what a phone battery pack gives a piece of fabric the size of a bed sheet. Here is what happens when you give the same fabric a hundred instead.
This page is an advertisement, and we would rather say so at the top than at the bottom. The customer reviews quoted below are public reviews of other companies' products, quoted so you can go and read them yourself. The electricity numbers are ordinary arithmetic and the working is shown next to each one.
- A hundred watts from a wall socket, not ten from a battery
- Heat across the back and middle, held in by flannel over sherpa
- About nine cents a night to run
- Covered through the thirty first of March, or we send a new one
The room is fine. You are not.
That is the whole problem, said in six words.
The heating is on. Everyone else in the house is comfortable. The thermostat says the number it is supposed to say. And you are sitting in a chair with cold hands and a cold back. Doing the small sums of whether it is worth another argument about the heating.
So you buy something.
Everything You Have Already Tried
- A wearable heated blanket that charges by USB — one hot strip across the back, cold everywhere else
- A space heater — it works, and then the electricity bill arrives
- Another blanket on top — warm only in the places you were already warm
- A sock filled with rice, three minutes in the microwave — genuinely warm for about ten minutes
- Turning the thermostat up two degrees — a conversation, and a bigger bill
Two of those actually work, and that is the part worth being honest about. A space heater does warm a room. A second blanket does hold in the heat you already have. The trouble is that one of them heats four hundred square feet to warm one person, and the other cannot make any heat at all. It can only keep what is already there.
The Number Nobody Prints On The Front Of The Box
A watt is a measure of how much heat a thing can make. That is all it is. The charger that came with your laptop is about sixty five watts. A kettle is about fifteen hundred.
Now here is the number that matters, and it is almost never on the front of the box.
A USB battery pack puts out about ten watts.
Ten. That is roughly what your phone charger gives you. And in a battery powered heated blanket, those ten watts have to warm a piece of fabric the size of a bed sheet.
They cannot. There is not enough there to feel.
How Much Heat Each One Has To Work With
Rated power of the heating element, taken off the product listings themselves
The grey bar is drawn at exactly one tenth the length of the orange one, because that is exactly the difference. Ten times the heat, into the same amount of fabric.
What Ten Watts Is Forced To Do
Put yourself in the position of the person making the battery version. You have ten watts. You have a whole robe to warm. If you spread ten watts across the whole thing, nobody feels anything, and every single review says so.
So you do the only thing left.
You squeeze all ten watts into one narrow strip.
A small area getting hot is at least something the buyer can notice. That is why the cheap ones have a burning patch in the middle of your back and nothing anywhere else. It is not bad manufacturing. It is the only move available to somebody working with ten watts.
A wall socket gives you a hundred. Ten times the heat, into the same fabric. That is the entire difference between the two products, and no amount of marketing closes it.
Yes, There Is A Cord. That Is The Point.
We are not going to hide it, because hiding it is how you end up with a product that does not work.
The robe plugs into a wall socket. Inside the length of that cord you can sit, read, work, eat and watch television. You cannot wander around the house in it.
Every company selling a cordless one is fighting that ten watt number and losing. We would rather tell you about the cord now than sell you something that never gets warm.
Where The Heat Goes, Shown Honestly
The heating element runs across the back and the middle of your body. Not the sleeves. Not the bottom hem.
That is on purpose. Warm the middle of a person and the hands and feet follow. The rest of the robe is thick flannel over sherpa. Sherpa is the soft fleecy lining. Its job is to hold that warmth against you, not to make any of its own.
We show you this before you buy. Three separate people left one star reviews on other companies' heated blankets after finding it out for themselves. That is a bad way to learn it.
The Second Thing The Reviews Say, And It Is Worse
We read the negative reviews on the cheap heated blankets. Hundreds of them. And the same sentence keeps appearing.
They do not break in the first week. They break in the second or third month.
One public review on Amazon is titled "Stopped working after only 2 months". Another says "Worked great for 2 months, now it won't even turn on." A third describes it dying "just a few days over 3 months".
Now put that next to the returns window those shops offer.
Thirty days.
Read those two facts together and you can see the shape of it. The window closes at thirty days. The failures start at sixty. The two numbers do not overlap, and they were never going to.
So here is ours, and it is built around exactly that gap.
Wear it every cold night this winter. If it ever stops heating properly, any time before the thirty first of March, we send you a new one. You keep the first.
Not thirty days. The whole winter, which is the only part of the year the question even matters.
What Each One Is Actually Built To Do
The three things people buy when one person in the house is cold
| A Battery Wrap | A Space Heater | This Robe | |
|---|---|---|---|
| Heat you can feel across your back | No | Yes | Yes |
| Warms you without warming the room | Yes | No | Yes |
| Under ten cents a night to run | Yes | No | Yes |
| Nothing to recharge | No | Yes | Yes |
| Covers you from shoulders to ankles | No | No | Yes |
| Heats the whole room | No | Yes | No |
| Covered through the whole winter | No | Varies | Yes |
One row in that table goes against us and we left it in. If what you want is the whole room warm, buy the space heater. This is for the other situation, which is wanting to be warm while the room stays as it is.
How Much Does It Cost To Run?
About nine cents a night.
Here is the working, so you can check it yourself.
A hundred watts running for five hours is half a kilowatt hour. The average American home pays about seventeen and a half cents for a kilowatt hour. Half of that is about nine cents.
Now the same five hours on a small space heater. It draws about fifteen hundred watts, which is roughly what a kettle draws, and you would not leave a kettle boiling all evening. Five hours of it is seven and a half kilowatt hours, which is about a dollar thirty.
A winter is about a hundred and twenty nights. So the robe costs about ten dollars of electricity across a winter and the heater costs about a hundred and fifty seven.
That is a hundred and forty seven dollars you do not spend, and it is the same sum you can do yourself with the three numbers above.
How Much Does It Cost To Buy?
A hundred and nineteen dollars, once. Free shipping. The matching foot warmer is included, and other sellers charge about twenty dollars for that on its own.
Then Why Is It Not Forty Dollars?
Because you have seen wearable heated blankets for forty dollars, and it is a fair question.
Three things account for the difference, and none of them is branding.
Ten Times The Element
A hundred watts of heating element across the back and middle, instead of ten watts crammed into one strip.
A Mains Controller
Wall power needs a proper controller and a proper transformer. A USB version needs neither, which is most of why it is cheap.
The Winter Guarantee
A promise that runs to the thirty first of March costs us money, and we can only make it because we know when these things fail.
That last one is the honest answer to the whole question. A shop selling a forty dollar version with a thirty day window has priced in the fact that you will find out too late. We priced in the opposite.
Questions People Ask
Is it safe?
It is a mains appliance and should be treated like one. Plug it into a wall socket rather than an extension lead, and unplug it when you are not wearing it. The factory has been making heated goods for sixteen years.
Can I wash it?
Check the care label that ships with your robe and follow it exactly. We are not printing wash instructions here until the factory confirms them to us in writing. A wrong instruction on this kind of product ruins it.
Will it cover me?
One size, and it is generous. Ankle length on most people, with a foot pocket at the bottom and wide sleeves you can pull your hands back inside. If it does not fit you, send it back.
What if it stops working?
Tell us any time before the thirty first of March and we send you a new one. You keep the first.
One last thing. If what you actually want is a warm room, buy a space heater and ignore everything above. This is for the other situation, the one where the room is fine and you are not.
