Can I run this 12V heated car seat indoors?

I fail to see the logic or reason in that statement.

Also, viewer's last post is much the same.
Pi would be a very large number without the decimal point.


If people do not use the correct terms then no one can know what is meant.

To anybody but an electrician, 12V is low voltage. Certainly to a DIYer. And the OP has clearly demonstrated that they're not particularly au fait with electrical things.

The route to solving such confusion is a constructive post - correcting it to "cut off the connector from the 12V side"- even pointing out the difference between LV and ELV would help.

Do you really think that the OP was about to cut the mains plug off that PSU, on the advice of greasedmonkey's post?
 
Second chair marked 2000mA and 12VA which don't seem to match unless for 6volt cars. Clearly not all items are marked correct I have seen 12 volt lamps for sale marked low voltage which clearly they are not. Anyway as far as this guy goes. This one from Ebay is about the right size I will guess was designed to run a 12 volt TV

Why does this matter? Surely when people say “low voltage lighting” it's pretty clear that they mean “12V”, so what's the problem?

This is not some pedantic technical point along the lines of “it's not an earth, it's a cpc” or “bulbs are what you plant in the ground, what you mean is a lamp”. If you start getting involved in doing your own electrical work, and start learning about regulations etc you'll come across references to “Low voltage”, and it'll be no good you thinking that that means 12V.

The Building Regulations, for example, which are law in England and Wales, contain a section on electrical safety, Part P, and the legislation says

The requirements of this Part apply only to electrical installations that are intended to operate at low or extra-low voltage….

So if you don't realise that “low voltage” includes your mains supply of 230V, you might think that the law doesn't apply.

This isn't covered by Part P though, is it?

WRT to the importance of not blurring the lines of terminology, I do agree. However, a comment of "No", and the link you gave is, in this instance not particularly helpful to the OP.
 
it would be cheaper to run the central heating. :)
 
*sigh*

Finally got around to unboxing the power adapter to connect it with the seat, and I've been sent the wrong one. Just double checked the order.

I had ordered one mentioned previously, spec:
OUTPUT : 12V ~ 1/2/3/4A, 48W(MAX)

And received one similar, but:

outputs: 19V, 3.15A, 60W (MAX)


Power consumption of the seat is:

HI 48 Watts / LO 36 Watts
Draws between 3 and 4 Amps
Fuse: 10 Amps


Ask for a replacement, or the difference is negligible?

Thanks.
 
You need to send it back. The size and material of the wires has been designed to give a useful and safe temperature. The resistance of the seat is fixed by the wires in the seat. The higher the voltage the greater the current through the seat and the higher the temperature of the wires. A higher current is likely to cause overheating which could pose a fire risk or at the very least shorten the life of the seat.
