If you want the "best" "cheapest" solution, then use a spare phone charger. I've been using a 1.5 mA HTC charger to power my main pi for what is quite literally a year now without any problems. I've also been using a 700 mA blackberry charger on my file server pi (it's headless so I don't worry about having too much current overhead).baker556 wrote:So my question really should be re-phrased whats the best cheapest plug
Hmm.. a slightly different question than the OP, but okay I have another system I rigged up that I occasionally use the analog audio with to stream Pandora (Internet Radio for those not in the states). On that one by pure happenstance I'm using a PSU from a dlink USB hub. I bought a female barrel connector for the dlink plug to plug into, then soldered a usb cable to the +/- terminals of the barrel connector. It's all enclosed in a custom made wooden enclosure (which is why i went with the barrel connector in the first place) and looks quite nice.omega1 wrote:Interesting comments about the HTC phone chargers. It's an HTC charger that is currently giving me issues (poor analogue audio quality) that has led me to this post from here http://www.raspberrypi.org/phpBB3/viewt ... 38&t=37038
My Wilkinsons charger is not Texet (thought they only did calculators!).rurwin wrote:The TEXET wired charger from Wilkinsons works fine. It "only" supplies 4.8V, but that's in spec and is at least as good as my "good" HTC charger. Its transient response is good and I can't force it to fail with a Pi attached.
Based on that, and adlambert's longer term evaluation and recommendation, I'd say it was a good choice.
It appears that today is May. The cheap one just arrived.rurwin wrote:I have my eye on one at RS that should be perfect. Unfortunately it's on back-order until May. They have another similar, but it's 1.8A and £19. I've ordered both.
