Apple Charger as Power Supply

[kristiaan_d]

Firstly I apologise for posting this as I get the feeling that many people like me have asked.

But, I am looking to order a micro usb lead for my Pi shortly and wanted to know if anyone has run it from an Apple USB charger? it gives 5volts @ 1amp so I cannot see why it won't work but just wanted to check.

Its a Model B Pi btw.


Thanks
Kris

I have used both iPhone 1A and iPad 2A chargers successfully. You will find both of these on the list of 'known good' devices at http://www.google.com/search?q=elinux%2 ... 20verified

I've tried two 2A iPad chargers and neither worked properly. With keyboard/mouse and ethernet connected I get a measurement of around 4.25V from TP1/2. Could be a fault of the cable, but it's the only one I have.

If they're Apple brand chargers, then it is definitely the fault of the cable.

I think Jeremy's right.
A lot of the cheap USB cables on ebay seem to be quite high resistance and cause large voltage drop. Kindle cables are pretty good. You can buy a Samsung branded USB to micro USB cable for less than three pounds and that should be OK as well.

I have both iPad and iPhone chargers. They work best with the shorter USB cords. The 6ft (2m) cords have to much resistance and drop voltage.

6 ft? Wow i thought the Kindle cable was long.

thanks for the replies guys, good to know that they work fine, I'm going to look for a shortish cable (i was aware of the whole voltage drop vs length issue).

I've got the memory card and bits just need a way to power it lol

I think you will find that the iphone charger is rated at 1 amp while the ipad charger is rated at 2 amp. Both are 5 vdc or thereabouts

Successfully used my iPad charger with 5V and capacity to deliver up to 1Amps .
power to Rasapberry pi was effected by Small usb port and i used my USB port to handle USB hub to connect with key pad & mouse
