Be careful what charger you're using with your Raspberry Pi
Raspberry Pi is a great tool for Linux developers, but it also suffers a little bit because of users’ ignorance.
The Raspberry Pi Foundation, the developers of this amazing mini PC, has seen a rising trend of broken Raspberry PIs because of counterfeit power supply units.
“Returned units used in the UK has noted a problem out there with some power supplies, all of which appear to be counterfeit Apple chargers. Some of you are using chargers you’ve bought in good faith which are not the real thing, and which don’t behave like a safety-tested, properly engineered piece of hardware,” said Liz Upton, a representative of The Raspberry Pi Foundation.
If you have a Raspberry Pi, don't use a look-alike Apple charger for it. You might ruin it.
Raspberry Pi relies on an ARM processor with a clock speed of 700 MHz, 256 MB of RAM, an SD card slot and a 5V Micro USB connector that supplies the power. It also features RCA and HDMI ports.
