Hi,

Not sure this is going to work with the Rpi but I found the ILUV IAD217BS power supply which appears to be a clearance on the Currys website. It's got 3 x USB outputs 1 of which can supply 1A with the other 2 supplying 0.5A. It's £3.97 delivered and as it ends in a 97 then its a clearance item so be quick. It doesn't appear to come with a micro USB cable so one will need to be purchased separately.

Also spotted is the international version of this at the Argos ebay outlet store which includes travel adapter connectors and its £5.98 delivered.

NOTE : Just to reiterate I do not know whether these will work with the RPi but I've bought the former to test.

Also a word of warning I bought 2 x cheap micro 1A USB chargers from ebay supplied from HK. On arrival one didn't work and the other died with a very loud bang and took my electrics out.

Seller refunded promptly and apologised.

Cheers

I've just ordered one of those from Currys too, we'll see how well it works when it arrives. I'm currently using a cheapo one that came as part of an "R-Pi starter pack" I got off eBay that consisted of the PSU+cable, keyabord, mouse, hdmi cable and a pre loaded 8GB SD card. However I ran into problems when I tried to use one of the 1-Wire Humidity sensors I sell with it connected to the USB port via a DS9490R# USB to 1-Wire adapter. The ADC chip on the humidity sensor was only claiming a supply voltage of 4.2V which I have confirmed as being the same as measured using a multimeter on the 5V pin of the Expansion header. I also measured the 3.3V line on the expansion header and only got 3.2V. It's a wonder the thing works at all really but other than the problems with my 1-Wire kit it does all seem to work perfectly.

Mine arrived today and currently powering my pi running raspbmc ok so far. Will report back over the next few days to confirm how stable it is.

Mine has also arrived and the power as measured on the board has gone from 4.2V with the first PSU to 4.3V with the new one. Still too low, so I'm starting to wonder if I've got a duff cable. A new one is on the way to try...

You've prompted me to measure mine now. I'm getting 4.55V which isn't great when compared to my genuine samsung charger gets 5.08V and the Pi has been bang on stable with that. I wonder whether there would be further voltage drops when any of the other ports are used.

Spec states that it should be : Output: DC 5V, 2A (1A + 0.5A + 0.5A)10W (5W + 2.5W + 2.5W) ..... no tolerance mentioned so it might have to go back.

Cable replaced with a good quality one and the voltage measured at te RasPi has gone up from 4.3V to 4.8V so it seems that the first power cable I had was of pretty poor quality.

Hello,
I was searching for info about connecting my 2,5 HDD to my Pi and to another power source. Is it safe for the Pi itself if we use a Y usb cable? I mean, is the power coming from the "red" end on the Y cable harmful for the Pi?

Thanks.
