🔋 Battery Life 🔋
I haven’t done a battery life test with it yet.
The blanket is rated to pull 4A at 12V.
The battery pack is rated for 3A at 12V.
It’s a 20Ah battery, so In theory I should get over an hour out of it!

You say "set myself on fire", I say "damn effective heating blanket".
Give a man a battery powered electric blanket and he'll be warm for a day. Give a man an incendiary electric blanket and he'll be warm for the rest of his life...
Hey, if it gets the job done...
Damn effective. I'm wearing it in my grave right now.
These are going to be all over Amazon in a month when a manufacturer in China sees this video and realises they can make them quickly and easily.
Nice project, glad it works.
They would probably just use the cheap 5v to 12v upconverters which they already make for USB2. Or connect three 3.7v standard batteries (the kind in these USB battery packs) in series.
@@CricketEngland at least it will keep you warm if it catches fire...
They’re already invented before this video
@@caleyhall ya think? It's almost as though the comment flew right over the top of your head, isn't it...
Matt Gray: I will make the blanket talk to the battery.
William Osman: DEATH CABLE
Michael Reeves: I will make an electric blanket.
Michael Reeves will make a blanket that tasers people.
Removing a button and breaking it, are the same thing.
I relate very much to this
Sincerely,
An Electronic Engineering Undergrad
I've added a load of info in the description, so please have a look in there! 🔋 And I’ve just added battery life info there too!
i will not try this at home :-)
yayyyy
@@maireadk5574 As you shouldn‘t.
The funny thing is there’s a couple of power tool companies that make heated jackets that use power tool batteries which can be pretty light. I think Milwaukee and makita do them
And aeg/rigid, ryobi, and a slew of chinese ripoffs. 5 min of googling would have solved this.
@@1990drewman then you wouldn't have this video to enjoy.
@@1990drewman This is better though, no need to be sarcastic and insufferable about this. My Makita tool battery has a capacity of 54Wh, my RAVPower PD power bank is 100Wh, twice the capacity, yet a similar weight, and while both are similar in overall size the PD bank is much thinner and easier to pocket (being longer instead) than the bulky tool battery. There are smaller tool batteries but they're still much bigger than equivalent PD power banks because they're optimised for high current draw which precludes high capacities and requires large, bulky heat dissipating designs, features not required when you're powering a weedy resistive heater instead of a high current inductive load. Not only that but this can also plug straight into an appropriate mains adaptor, including many modern laptop adaptors that your friends might have laying around. Tool manufacturers make all sorts of silly things powered by their batteries not necessarily because it's the best way to power something but instead just so you've got more stuff that forces you to use their brand of battery, that doesn't make them the best approach to solving the problem of powering something, particularly if you aren't already at a job site as a contractor with dozens of spare tool batteries lying around.
Colin Furze is now drawing up plans for a pulsejet powered version.
Just put gaming laptop on blanket and run crysis remastered
Someone who knows Latin: I've got chills they were multipy'in, now this blanket it's electrifying...
The only thing I would have done differently is that I wouldn't chop the connector of the blanket and instead found a corresponding one and made a cable with usb-c on one end and a 12v barrel plug on the other. I'm assuming that the connector is of the barrel type of course.
Yeah, I was think just make a generic USB-C to cigarette-lighter/accessory port: then Matt could use it on the electric blanket, a portable kettle etc
@@beebware if I'm not wrong the connector on the blanket is a standard barrel plug. Like on a laptop. And I was thinking about putting the father side on a cable. It is a lot more compact. And is easier to source.
Edit: father not farther
I'd replace them for XT6 connectors or similar
@@SamValiant that is also a possibility
@@beebware you’d fry the battery bank trying to power a kettle
On behalf of NHS community staff forced to see clients outdoors... I WANT ONE! Seriously, there would be a heck of a market for this thing.
Something like a cape or cloak, not so much a bed-size blanket, which could get cumbersome to handle.
@RevdKathy Uh, hi! I am 3-4 years late, but there are USB powered heating vests! Search around a bit, you should be able to get a good one for about 40-50 quid ☺
I remember a while ago seeing coat warmers that plug into drill and power tool batteries. No idea if they still exist but they could be a good option!
I actually had a look recently before this video and Makita makes one and there's a few that also plug into USB power packs. They are expensive though especially the power tool ones.
For soldering I always use a blob of blue tack to stop everything moving around :)
D'oh! Why didn't I think of that?!
I use blue tack instead of solder
The button breaking is a real "Task failed successfully" moment.
Thoughts at the beginning: I can't imagine a small power pack would be able to run a blanket for very long at all. The blanked probably pulls 15+ amps, so it might run for an hour if you're lucky.
i am. absolutely incredibly atechnical but this was rly fun to watch! would not be opposed to more 'matt making things'
this man makes me happy
As a fire restoration tech I'd have to say like 20% of the fire I went to where because of heated blankets.
Mains though, right?
I love how silly and goofy you are while being extremely intelligent.
Helping hands are pretty fiddly, I find just a bit of masking tape often does the trick. Ace video and stay safe! :)
A large blob of blu tack works wonders 😉
Modifying cheap electronics to function in unintended ways... this video has strong Big Clive energy.
This is how humans will evolve eventually not the other way around, where big fat cat CEOs and corporations reverse engineer things so we can never unlock their true potential
I very much remember brown is live for U.K. because of Tom's review of British plugs from forever ago.
Matt flexing that fluke multimeter and all us plebs with our middle of Lidl multimeters
That was also thanks to everyone who bough merch :D
@@MattGrayYES it would take a fair bit of merch to buy a fluke😁
I am happy to say I have the same multimeter as Matt Gray
Why is this more relevant now than when it came out
If you want a marginally less janky setup, there's actually a few extra-chunky USB power banks which include built in 12v cigarette-lighter output (or even conversion to 120v AC). So you could achieve something like this without having to modify cables or push things too far out of specification
i've got this engineering friend, his primary role is to shoot down bad ideas by idiots (me.)
I can already hear his groans and sighs in my head just reading the title.
Mat grabbing the USB from the positive and negative to disconnect it at 4:40, please don't get shocked
Noticed that as well, to be honest it was done only using one hand on conductive parts while in 12V mode so it's not anything like the worst thing that could happen with electricity.
But I agree that it's definitely important to be aware of what you're touching when working with electronics, even in these relatively low voltage and power limited scenarios.
Trying to decide if this beats the glittery shoes or not. Bloody brilliant either way.
You could have got a car booster (jump starter) pack. They have a 12V output (often with a cig lighter adapter as well for an even simpler hookup). They usually have 5V USB output also (don't buy one that doesn't!). They will jump start your car when your battery is flat. TBH they are the ultimate battery power banks.
I had the same idea... and I have the exact same RavPower battery bank.
Talking from experience this is the true sound technician way of doing things quick and brash but it works
I'd love to see any more electrics projects you'd care to upload.
Love it when a plan comes together
A big blob of Blu-tack is a very handy ‘helping hand’ when soldering
There is Something like this, Bosch Profesional sels Heated Jackets which are powerd with an Adapter from there 12V or 18V Power Tool Bateries. To connect those to components they use a Plug that locks fairly simular to the one on your Blanket, so powering an Blanktet with it seems posible. Those Adapters are also sailed seprat as GAA 12V /18V and have one or two USB A Charging Ports in adition to the 12V Plug, so this could be a good Option if you alredy own the Batteries needed. If you´ve got both 12V and 18V, buy the 18V adapter since it is cheaper, has two USB ports, alows you to use bigger Bateries, and dosen´t discharge your Baterie when it is not used (thats a known Problem only with the GAA 12V)
As winter weather is starting to roll in. I would so buy a Matt Gray USB blanket.
Thanks, mate. Needed some smiles and chuckles. And a bit of wiring how to. Off to the closet to find the blankets!
This has subtle like, james may vibes and i am here👏for👏it👏
I know someone who would do this if I tell him about it. My son, your dopplegänger, also a radio audio engineer. He's a warmth-lover. Now, do I dare tell him about it...?
Do it.
Very charming.
Now that was a warming story
A warm Matt is the best Matt
I suppose that this creation is being quite useful this week
If you don’t have helping hands, blue tack the wire down!
Blue tack the PCB down is easier, but right idea.
Is no one going to mention that this idea came from Matt meeting up with some friends in a park? Is there any chance we may see a park bench video soon?
I love the ingenuity of this idea regardless!
You want the voltage to remain? Better keep that button away from any referendums then!
You can get some pretty small 12V jump packs now which could be a simpler alternative.
I found myself thinking the same thing - a car jump-starter pack's 12v-output. You would want to use extreme caution if using the Big Chunky Connector on one of those because they can dish out an absolutely gargantuan amount of current if you accidentally shorted them - probably best to add a fuse!
No no, there's a much faster solution:
1. Find a fully charged lithium-ion battery.
2. Stab something completely through it, like a knife or ax.
3. Jam the battery into your pocket.
Instant warmth! Job done.
Brilliant!
How long does the battery last?
I haven’t tried it yet! But the battery is 20Ah, and it says it can supply 3A at 12V so I suspect at least an hour! (If the blanket doesn’t self-destruct before then!)
@@MattGrayYES On the bright side, if it catches fire, it'll keep you AND your friends warm.
@@MattGrayYES I will expect an update...
@@beef_enchilada3384 To get the most out of it, one should plan for the blanket to catch fire just as the battery is about to run out. That way you stay warm/hot the longest possible time.
@@MattGrayYES you should have measured the ampere usage before (On the car-module). These USB-C adapters can not transfer more than 2 amps permanently without breakting (use them for multiple projects). Either the adapter burns away or the powerbank is strained too much. Please feel if the powerbank or the adapter gets hot when using the blanked.
Don't want a slightly burned Matt.. :/
@10:26 if your blanket does not have a heat control button you could use the one on the usb controller to give less power and hence lower temps..
Alternative title: apartment fire any% speedrun
I've only seen brown and blue used with AC cables. For DC, I've always seen black and red, or black and black with stripes.
Very nicely done. Yes, often a car battery gives more power, for example CB radios and CB mains PSUs are 13.8 volts.
How many Amps does the blanket draw? I don't think the power bank would last that long ( although it is 20000mAh..)
And your happy giggle at 13:35 made it totally worth watching this video! (I'm more of a thermos person myself...)
If it's bad enough to be using mains cable with mains standard colors for a relatively low voltage DC system, *never* trust the colors to be anything sensible. In fact, even if they're red and black, don't trust it. Always test.
Aww, there's a framed picture of him and Tom in the shelf
Great info!
I'm not a big fan of helping hands as well but I find a bit of blue tac "The stuff you use to hold posters" to work really well.
This is actually really useful because I've been wanting to convert a 9v portable video light I have over to USB PD
Someone who works in tech that's right handed *skeptical glare*
One of these would be... whatever the opposite of naff is while waiting for the hovercraft bar to hover by. Top-notch, maybe?
THIS IS THE CONTENT I SIGNED UP FORRRRR
They now make USB-C PD trigger cables that would let you plug from the power bank straight into the electric blanket's connector.
I choose to believe that those are the result of this video.
Maybe make a radium blanket next... no battery needed!
I mean the powerbank is an extra hand warmer i guess?
They make heated vests and jackets already too
If it sets you on fire, at least you will have a fire blanket nearby.
IT'S ELECTRIFYING!
Now you’ve got to make one for all your friends!
12v heated jackets are a thing...I own several...and I live in Australia...our winters are only 1C.
This is what us Aussies had to think about a few months back, although cold for us is probably a nice temperature for you.
I'm not in the UK, but I am somewhere with a very similar climate. My great uncle moved to Australia, and when I was growing up it seemed like every year we'd get a letter from him in July or August complaining about the cold winter weather...which was roughly the same temperature we had at the height of summer.
Matt, I love your videos. Keep up the excellent work! :)
I just have a 12VDC heated hoodie, much easier.
Awesome project.! I am going to be one of those people and say what "you should have done" what I mean is what I would do. For the pcb I would have coated it in hotglue to keep the button from being pressed that way if I ever need to reuse that thing or it some how loses its program I can take the glue off with alcohol. I also have a 3d printer so I might have designed and printed a housing for it instead of heat shrink but I know not everyone can do this. Otherwise I don't know what else I would change as this is such a great project.
I also might have just been really lazy and built a 12 volt nicd or nimh battery pack for it as I have access to cells and a tab welder at my job. While this does mean you don't need a special pcb for it you will be stuck with a custom battery that would be hard to use for other things. Compared to the lithium battery pack in this video its an easier method for me personally but not as versatile. It would also weigh more to get the same mah capacity/energy density.
Matt if you read this I highly recommend getting a 3d printer. If you do a few more projects like this and reach out to creality or anycubic I am sure they'd send you one to review for free.
I own a helping hand. Can confirm: not useful.
just going to point this out as a biker
some biker jackets have heated elements as do some insoles gloves etc
they run off a cig lighter socket
you can get cig lighter sockets that plug straight on to a motorcycle battery
and a motorcycle battery does not need to be connected to a bike to work bish bash bosh a lot better
Exactly what I needed today :)
Your video that is!
Super Glue kills buttons and switches. A little dab and it'll never work again.
I want Big Clive's opinion on this
I'd love to do this, but my experience with soldering was soldering my mates trousers or books to chairs at school...
Now fashion the blanket into a Jacket and you've got yourself a Fashionable electric jacket
I’m not an engineer, but I’d have tested the blanket to see how it reacts if it gets different voltages. At the very least to see how the red “on” light behaves if fed 5 , 9 or 15 volts.
We need a "two months later" report on this... Did it burst into flame? Did the batter bank melt? Or did it just work? I wondered just how many amps it wanted vs how many the batter bank could supply.
Big Clive 2.0?
Matt's thoughts: "If you can't be a goof model, be a notable warning"
Unless you make at least one more you'll be outside by yourself
I probably would have tried ripping out a laptop's power supply unit and using the 12 volt rail on that that's probably way harder than I make it sound
I'm 2 years late to this video, but are coats in the UK really so poorly insulating that you need blankets on top? Honest question! (I'm Canadian, our winter gear is reliable.)
Bic lighter is a good heat shrink tool just saying. Gun be good to take decals off ur car.
Where did you learn to do this sort of thing? I've always been curious about electronics but I don't really know where to start learning about it.
There is already usb blankets for sale
These do exist already (Amazon have hundreds of them) not sure if your way was cheaper though
Great project, I would do similar myself (I'm an engineer, I can't see anything wrong with doing it) except for the fact that a. I don't own an electric blanket, and b. I don't have a USB power bank either.
Surely its USB 3.0 that would've introduced the variable voltages? Since USB-C is just the connector type, and the power bank you have just has standard USB-A ports on the output (but blue, signifying they're at 3.0 standard)
His battery pack has a Type C-with-PD output on it. Blue USB3 "type A" connectors can't do Power Delivery, that's a USB-C specific trick. And as he noted at one point, not all C-PD outputs can do all the voltage options. I think there's also meant to be a signalling thing built in to C-to-C cables to let them tell devices the maximum current they are rated for.
Matt, how is the blanket holding up? And how long does the blanket stays warm? Thanks.
Excellent little project! Whats the power rating of the blanket Matt?
How long does that battery pack last? Is this viable for a few hours in a pub garden?
battery powered jackets are a thing
