🔋 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!

@clancywiggum3198 3 года назад

@@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.

@schenckinator5427 3 года назад

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)

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.

@turingincomplete6844 3 года назад

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

@x9x9x9x9x9 3 года назад

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.

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)

@MattFowlerBTR Год назад

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.

I really need to look into the differences between USB-A and USB-C. I just use USB-A since that was the wires I had. Then since those were the power bank i had that was the cords I bought. It is a vicious cycle.

@extrastuff9463 3 года назад

Also important to keep in mind is it's not just if USB-C sockets are on there, these protocols can even live on a type-A USB socket! Essentially you'll come across these 3 variants: - Nothing special, just 5V output up to a certain current - USB power delivery (the non-proprietary protocol option) - Quallcomm quick charge (what a lot of phones with fast charging early on used and probably still do) There are also a few versions of quick charge out there, last time I checked they were up to quick charge 4 already. USB power delivery has also gone through revisions as well, not sure what the differences are there. But once you figured out which variant your product needs you also need to check if it supports the specific output profile, like Matt here in this video discovered: his mains USB power supply didn't have the 12V option but his powerbank does.
