Power Supply specification for Raspberry Pi Type-2 Model-B 1GB RAM board

Can you please let me know the power supply specifications i.e. DC voltage and current rating to connect with Raspberry Pi Type-2 Model-B board with Raspberry camera.

There have been a number of people recommending using a 2A PSU. Especially if you're going to load up the USB ports.

Here is what one person did to measure with kilowatt and the various activities on old Pi Model B (which was very power hungry). http://thomasloughlin.com/update-raspberry-pi-power-consumption/ From what I know the new Pi 2 is comparable to a Model B+ give or take. See this one http://raspi.tv/2015/raspberry-pi2-power-and-performance-measurement.

So enjoy, be happy!

I would recommend that you use a minimum 5v micro usb adapter of 2.2 amp (2200 mA); especially if you are going to use two or more of the usb ports, ei, a keyboard|mouse blue tooth combo and a wipi for instance.

I ran my RPi b+ with 2 amp supply for quite some time... no problem. I am using a 2.2 amp supply with the RPi 2B

Regards,

I've been testing the RPi2 and am currently still using a 5V 1A power supply without any problems (Blue Star travel charger 5V 1A).
I've done CPU tests where the 4 cores were using 100% with 1 USB keyboard and 1 USB mouse attached, I also did not have any problems during those tests.
If you still have a 1A power supply you can try using that one, if you need to buy a new power supply however, then I would suggest 2A (or 2.2 like Mark suggested).

Edit:
Note that I'm not drawing (much) power from the HDMI because my HDMI device has it's own power source. Since you're using a camera module I would go with gadget.iom's or markhaysharris777's suggestion.

The power requirements of the Raspberry Pi increase as you make use of the various interfaces on the Raspberry Pi. The GPIO pins can draw 50mA safely (that is 50mA distributed across all the pins! An individual GPIO pin can only safely draw 16mA), the HDMI port uses 50mA, the camera module requires 250mA, and keyboards and mice can take as little as 100mA or over 1000mA! Check the power rating of the devices you plan to connect to the Pi and purchase a power supply accordingly. If you’re not sure, buy a powered hub.

I Use a 2.0A one, and it never misses a beat
