Hi all,

In a bid to heat my home office chair, I've bought a 12v heated car seat cover, assuming I could just plug it into a cigarette lighter adapter from ebay.

Item in question:
http://www.amazon.co.uk/12V-Heated-...=1385421518&sr=8-1&keywords=electric+car+seat

However, I don't know how much power the seat will draw, and if regular cheap ebay 240v to 12v cigarette converter will be powerful enough to run it. Any ideas?

For example, here's an adapter:

http://www.ebay.co.uk/itm/MAINS-TO-...ories_MobilePhoneChargers&hash=item3a6a549f81


The cheapest adapter on Ebay for example states it can only output at up to a max of 450mA. Would I be better off buying a generic 12V power adapter and connecting it to the seat?

Many thanks!

On first read of that Maplin product i quickly looked to cancel my amazon order - but then read the reviews in the nick of time, and was glad I didn't. Apparently a disappointing turn out. But thanks for pointing it out, it otherwise looked great.

So... to power the 12V one I'm getting... :)
 
List of things to do

  • Wait until it arrives

    Look at the current rating information that will be printed on the product information or on the device itself

    Buy the relavent adaptor

    Make appointment with doctor to sort out the fungus that will form in your backside
    :LOL:

and buy thermal socks as you feet will feel colder. Blood will be diverted from the legs to cool the buttocks and thus less blood will reach the feet so they will get chilly.

If the seat is 5.4W or less that one will be fine.
 
Ok, my electric car seat, planned for an office chair, has arrived through the post. It states:

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

So, could I use this?

http://www.ebay.co.uk/itm/MAINS-TO-...ories_MobilePhoneChargers&hash=item3a6a549f81

It's suitable for 450mA apparently.


Or connect the seat with this:

http://www.ebay.co.uk/itm/300mA-UNR...ctronics_PowerAdaptors_SM&hash=item35cd78a3be

Output 3v, 4.5v,6v,7.5v,9v & 12v DC at 300mA


Many thanks!

Look it draws between 3 and 4 amps

A milliamp (mA) is a thousandth of an amp so you will need a power source that provides 4000mA (= 4 amps)

The two items you have linked to only provide 450mA and 300mA

You need something MUCH BIGGER

Something like THIS might do it (no guarantees).

Or return that seat and get something designed for use with mains voltage.
(as already advised)

Why ask questions if you are not going to take any notice of the answers?

You've known for a week that a 450mA adapter will only be able to cope with a 5.4W load...

and here you are asking it it could power a 48W one...
 
Come on, it's clear that the poster did not understand the terminology or units. Just because you know the difference between milli and kilo doesn't mean everyone does and decimal points are not part of everyone's life. Saying it is OK for 5.4W may be true, but there are many people, for example with forms of dyslexia or numerical blindness, who will just see 54 for the adaptor and 36 for the seat. Please don't insult these people, just accept that you're lucky to have the brain and senses which allow you to make sense of the world.
 
eBay item =121177869966

Cut off the plug from the low voltage side and either hardware to the seat, or add a cig lighter socket to plug the chair into.


Something like this maybe Item #: 190990356906

Wasn't necessary here. Not knowing that 450mA is the same as 0.45A does not stop someone from knowing that 5.4 is a lot less than 36 or 58.


and decimal points are not part of everyone's life.

Neither is vision, or having 2 functioning legs etc.

It is unreasonable to proceed here as if people are so limited in their abilities that they cannot understand things taught to 11-year olds, or seen in shops everywhere. Decimal points may not be "part of everyone's life", but they are unquestionably part of everyday life.


Saying it is OK for 5.4W may be true, but there are many people, for example with forms of dyslexia or numerical blindness, who will just see 54 for the adaptor and 36 for the seat.

I'm sure there are, but see above.

Would you rather I suggested to the OP that if he cannot understand the difference between 5.4 and 54 then he should not be trying to buy separate electrical appliances which need to be matched?
