cheap ups supply

Sun Jan 27, 2013 10:02 am

Hi looking for a new battery for my phone and found this

http://www.ebay.co.uk/itm/Portable-Batt ... 56414886de

might not have enough power at 800mA but cheap enough and can be used for any micro usb device
also has mini aswell as micro usb supply socket which is handy.

I notice that the output voltage is specified at 5V +/- 0.5V. That is outside the range that the Pi requires (5.0V +/- 0.25V).
It says it has a capacity of 1500mA, an input current of 500mA and a charging time of 2 hours. Those numbers don't add up. Even if it was 100% efficient, it should take 3 hours.
It may also foul the SD card if you plug it in directly.
I would avoid it. Braver people might use it with care.
