I also over-specced the current too. When they say "minimum 700mAH", they really mean "it will light up with 700mAH, but its behaviour will be odd at best". (I have the older model B..newer models may ask for more or less power) I bought a quality 2000mAH supply and have had zero issues since (2 years or so). It's quite boring now :) Mine runs headless and has a 32GB USB stick as main storage, with the OS on SD card, so as far as power requirements go, YMMV depending on how you use it. -- - http://surfcoast.redbubble.com | https://picasaweb.google.com/107747436224613508618 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "Unless someone like you, cares a whole awful lot, nothing is going to get better...It's not !" - The Lorax -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- A committee is a cul-de-sac, down which ideas are lured and then quietly strangled. *Sir Barnett Cocks <http://www.quotationspage.com/quotes/Sir_Barnett_Cocks/>* -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "A mind is like a parachute.
