i have got this. comes in handy very often

voted hot

For those wndering this is a regulated unit.

Got one a couple of years ago, very good quality!

This only goes up to 7 volt though! Order with caution!

Does anybody know OHM's law? I have a device that as an input of 25 watts X 4.8 volts. Will this adaptor be ok?

Power = Volts * Current

This means that 25W @ 4.8V requires approx 5.2A, so this is no good to you (i.e. 2500mA = 2.5A).

I = P / V so 25 watts divided by 4.8 volts equals 5.208 Amps


see Above...hrhr I obviously took longer to work it out and type >

you have that wrong watts / volts = amps
so 25 / 4.8 = 0.191

edit I need to go back to school with that maths lol its 5.208

is this any good for appliances / players got from the US which need a 110V power supply?

If you mean a 110v mains adaptor, i.e. drops from 110v to 5v then this would work, however it will not convert 240v to 110v

there is also this one
argos.co.uk/sta…htm
or item number is 982/9701
that has 3, 4.5, 5, 6, 9 or 12 volts.
and works out to £6.97 so slightly cheaper
so may be better for someone who want different voltage

djnaff:

You, me, and Mugwomp are all quoting the same formula - we're all just transposing it to show the terms in different ways.

I think you'll find that it's your calculation that's wrong. Since when is 25 divided by 4.8 equal to 0.191? It's obvious that the answer should be somewhere around 5.

I see now i should go back to school its been a long time

Please note:

Output :- 3/4.5/5V DC 2500mA;

6/6.5V DC 2000mA;

7V DC 1900mA

Too many volts you can damage/fry your device. Too few it will not have enough power to work correctly.

Too few amps your power supply will burn out. Too many is fine, just means its tougher than you need.

If you want something more powerful I bought a 12v 5amp power supply from digidave on ebay for £15 which was a bit much but much better than throwing away the lcd monitor, which has continued working just fine for a few more years. Muliple connector sizes but only one fixed voltage. It was the only place I could find one at the time about two years ago. Some of his bidding auctions go cheaper but I was in a hurry and did buy it now.

Anyone looking for specific power supplies then [url]www.CPC.co.uk[/url] have most. but the delivery can be steep for a single item.

Check the label of any you are trying to replace many have standard No.s so you can make sure you get the right type and not just match the volatage and wattage.

OK I don't know much about this kind of thing. I'm wondering if somone could help me out here, might be a little off topic. When I go on holiday to Trinidad I usually take my PS2 or Xbox and I also have a dvd player there too. All are from England and have the normal 3 point plug. I bought a type of converter that allows me to use the PS2/Xbox and dvd player overthere and everything works fine. last year I took my xbox 360 I used the converter and it worked for around 30 seconds then i got the 3 red lights which usually means the xbox has a hardware error and need repairing. So i assumed it got damaged on the way to Trinidad, anyway when i got back to england it was working fine which leads me to believe maybe the xbox wasnt getting enough power in trinidad? if thats the case to i need a new more powerful converter or does anyone have any ideas what happened, thanks in advance.

This should work well with an invertor in a car too - even Hotter.

is this one any good- free delivery.-]http//ww…219

hi mate
dont think the red lights was caused by using it in trinidad personally
when you get the 3 red lights "yes" it does mean normally an hardware error
but if you leave it a while it will normally work again for a while
and then red light again
i personally know people who have encountered the 3 red light error only a couple of times with no freezing and theres is still working fine.
what you normally get is games start to frreze then the dreded 3 red lights
it is only a cheap fix to have done via ebay normally about £25 (xclamps)
or if you havent opened up your 360 (i.e flashed) microsoft now offer a 3 year warranty for 3 red lights
hope this helps
