USB AC Power Adapter for Samsung/iPhone/MP3/MP4 (AC 100~250V/EU Plug)

Pros: Like the summary says - if you need a charger for your phone/tablet/gps/whatever look no further - this is the one. It doesn't say so in the specs, but what you get here is a charger that gives you the full 1A as opposed to many third party chargers out there, meaning that your charge is as rapid as you'd get from most of the "originals". Price is wonderful - here in Spain I'd have to pay 3-4 times as much for the same type of charger.

Cons: Haven't found one so far.

Other: Get one... or two... or three! You won't regret it...

Pros: The device is very cheap, in the Netherlands a device like this costs around the €7. This is around the $9. You can buy 2 of these for the same amount of money.

Cons: Tested 2, only 1 works properly on my raspberry pi. The 1ste one only outputted 4 volt, that isn't handy when you want to power a device that needs 5V and 0.7a. But the 2nd one works very well. I have 3 left to test, I hope there is an other one that works because I ordered a 2nd PI.

Other: If you want a good adapter, then you need to order a few of these. I guess this is the best choice at the moment.
