Safe power adapter?

Tue Jan 22, 2013 5:15 pm

When my Raspberry Pi first arrived, the first thing it did was blow up the power adapter I had lying around here (still, glad it was the power adapter, and not the Raspberry Pi). Since then my Raspberry Pi has reached an uptime of almost 2.5 months, using my cell phone charger. Of course this makes charging my cell phone a bit troublesome at times (always need to remember to charge it in time, because I need to charge it on the computer).

So could anyone tell me whether any of these two power adapters would be safe to use for powering the Raspberry Pi (Model B, 512MB RAM)?

Thanks.

The first one only outputs 500 mA, and the Raspberry Pi requires 700 mA. The second one provides 1000 mA, so it has enough power for the Pi and more.

This one should do:

- Output: DC 5V/1000mA±5%

If this is true it will work, often times it's not true.

Well,

my first 1,0A USB adapter blow also here..

I Found an "ULLpower 1,2A Model SAW-0501200 ( 100v-240~ input, 0,3A)"
max Outout : 6Watts

Have a look at: http://www.conrad.de/ce/de/overview/211 ... -Netzteile

That works fine for me and not overheat .

Kind regards

for 256MB Pi's the USB Charger adapter would work "Ok" for you using the ones that come w/ the Kindles. but i've been using my wall out adapter for my Dead TrendNET Router (5v 1.6A) and its had enough for my 512Mpi to do a Wirelss Wifi adapter + my new Wireless keyboard/Mouse unit without the need of a Powered Hub.

I've just received it (apparently a power adapter is suspicious according to border control), and it seems to work fine :)
