Do they have any 2A Micro Usb ?

I'm running my Pi with this, and it copes fine powering a wi-fi adaptor, wireless keyboard/mouse and small led circuits running off the GPIO.

I agree I'm running a wifi and other peripherals with this adapter and its fine. I'm in the market to buy yet another one to give the folks a media centre.

I have a few apple chargers lying around 5v 1A i presume i can just use a micro usb cable and shazam?

Banned

Isn't this just a micro USB charger or this there something special about it?

I've had issues with PSU's and the Pi theirs no way that this would run the Pi without issues in my opinion , i had to buy a 2.1amp as that's what was recommended by the forums and since then ive had no trouble at all before everytime i fired up a 1080p film in XBMC the Pi would reboot and that was with a 1amp PSU this is cold as its not upto the job and you will be throwing your money down the drain do yourself a favour and buy a more powerful 1 and have no issues than buy a low powered job and have funny behavior.

COLD

It's about the qaulity of power alongside the current imagine an AC signal being coverted to a DC one, if it's not done properly then you'll get dirty power with spikes and not a clean square wave as intended. I've tested an overclocked rap pi @ 1GHz sreaming 1080p and it was using 4.2 watts at most (less than the 5 watts a 1amp 5v adaptor is rated to)

which model was that as i have a 256mb ram version that ive had since launch maybe the newer ones with double the memory require less power.

Ah that might be a slight issue due to improved fabrcation on the newer ones; mines is the newer 512mb model B. Have you tried using a good quaity mobile 1A phone charger?

yes it will, unless you've used this psu don't judge. This runs a pi more stable than a 2A charger I have. I have had this streaming a pi camera at 1080p over wifi for weeks now without any issues...

looks like good alternative charger from recognized brand for my mobile

Charge a Nexus 4?

I'd def get 2A *minimum*...

Another misinformed person... A good quality 1A is going to do the same as a crappy 2A one. 2A adapters are considerably more expensive too..

Nice just bought a model B Pi for just under £25 from Amazon new (I posted the deal but it got taken off because the seller has no rating?). I have a dual USB surge protected single socket which I read works well, if not I'll have some of this. Thanks

A square wave? Really?

I have tried and tested loads of different PSU's with the r-pi and it all depends on what you want to do with the unit. If you want to install XBMC and overclock it so it runs nice and fast then I doubt you'll get much joy out of this. I could well be wrong as I don't think I've tested this particular PSU but all the 1A ones I've tested so far are unable to OC any higher than "moderate" settings. To get the best out of the XBMC on the r-pi you need to use a USB3.0 stick (yes I know the r-pi only has USB2 ports but USB3 is still quicker - even on USB2 ports) and you need to overclock. The most reliable "cheap" PSU I've found is the Nokia AC-10X charger which I've bought a few of from play.com for £3.75, although I think they may have gone up a few pence since I last bought some. That outputs 1.4A at a steady 5v and although it's not quite good enough to do "Turbo" overclocking but it does "Fast" with no problems.

If you want the r-pi for something basic then I'm sure it will do the job just fine.

How accurate is your power meter at such tiny currents?

Sorry I meant a straight line DC signal, I thought we were having the HDMI signal arguement ;-) Seriously though, my bad.

I'd say +- 10%, power adapters can usually be pushed a little past what they're rated at but i've not seen it go anywhere near or past 1A. Some of the smarter engineering type people on the ras pi forum will probably have much more accurate figures.

That's a terrible way to calculate the power draw of a Pi. You don't know the efficiency of the DC converter, and you're at such a low power level that I would bet your 240V power monitor isn't going to be that accurate anyway (never mind the effect of power factors etc. on the AC). Stick a DVM on amps range in series with the 5V supply to the Pi and you'll get a much better idea of what it needs.

Can anyone tell me the best place to buy a pi? Looking for the newer 512mb

I'm still using iPhone (genuine) chargers for my 2 Pi's. Not had any problems with one running as a web server and another as a NAS. Is it worth switching to these?

As stated this will work fine if you intend to run the Pi at stock clocks with a powered USB HUB or few USB powered components connected.
If however you intend on overclocking then you will need something with more current 2A+

I struggle to believe a raspberry pi overclock needs a bigger power supply. This seems to suggest perhaps 80ma extra current draw moze.free.fr/blo…php?

I suspect people were overclocking on power supplies that couldn't provide stable voltages which when overclocking caused instabilities. I'm fairly sure this power supply will be fine for overclocking.

I would be very interested if anyone has proper evidence to show it would not be, or that the Pi somehow doubles it's current consumption when overclocked by a few hundred mhz...

What the heck, it's so cheap I think I might buy one and see how it goes!

I've already got a load of 1A PSU's kicking about but as you say it "should" be up to the job if it's a stable 5v. Oh hold on, thinking about it I'm already running a wireless keyboard on one USB port and the OS is installed on a USB stick in the other port so I'm not so certain this would be up to the job as it has to power those too. I know they also take minimal power but it all adds up... Ideally I'd like to clock up to 1000/500/500 as I know a few are running that with no problems on the ipad charger but I can't quite get there on my Nokia AC-10X charger. Hmmm is it worth a punt I wonder?

Whufclee .. That's exactly the point I'm at, and why I posted this deal My thought was, if endorsed by the foundation, then it must have been put through it's paces and met with approval.

Still waiting on mine arriving, but fingers crossed it should do the trick.

Ok I've also ordered, I'll let you know how I get on when it arrives

Whufclee.

Mine turned up an hour ago, installed a fresh version of OpenELEC 3.1.7 to a SD card, formatted a cruddy old 4GB USB 2.0 stick using your excellent video guide on XBMCHUB, and fired it up with the new PSU.

All fine and dandy. Reset to defaults to bring the USB stick onboard, added my own personalised settings to Modded Confluence Vol. 2 (Thanks mad-max!) and restarted, added Videos and TV links (Library export to individual folders)

Added 1000/500/500 to config.txt, reboot, all is very VERY good so far!

Got mine this morning and so far I have to say it's brilliant, I've not given it a proper test but initially looking very good overclocked to the same as you have. I'll give it a proper test tomorrow and if all is good I'll be replacing all my nokia chargers

Thanks mate.

Good to hear, so far I've had no problems whatsoever with mine, not crashed or hung once.

One problem I do have though is this, and it's doing my head in. I have my Movies and TV metadata exported as single files into their relevant folders, on a fresh install, and after setting the content accordingly, a "Scan for new content" or "Update Library" both set the scrapers to work, but take hours to complete? From everything I've read, they should recognise the locally stored info rather than scrape from scratch, but this doesn't appear to happen, any ideas Whuf?

Like you say it should just scan the information from the nfo files. I personally export my video library as a single file and have everything scanned in as the network location (even if the content is stored on the local machine). So for example I would set the source up as something like SMB://WORKGROUP/LEE-PC/MOVIES/ and then that way if I ever have to update any system on my network I can just use the same backup. If you have multiple devices sharing the same library then setting up a shared mysql database works great with this method too. I know it's not the answer you're looking for but that's all I can tell you I'm afraid.

Just wanted to update, I've now been running this for almost a week now and the only lockup I've had was user error (I accidentally pressed up on the remote whilst playing an rtmp stream - xbmc doesn't like that!). Brilliant little PSU, just going to order a few more for myself now, just been through all my bits and pieces in the workshop and I appear to have 6 raspberry pi's in here that all need PSUs

I've tested mine a little but need to adjust the txt file to get 1920x1080 on my Dell ST2220T

Isn't the Dell a native 1920x1080 res? If you're running XBMC you just need to set the output res to match?
