What's a good mains charger (uk) for phones?

I bought a duracell one, thinking duracell is a good company... and it barely gives 500mA, sometimes 1000mA output even though it says clearly on it 2100mA. Meanwhile my friend's samsung charger easily gives off in a few seconds a constant 2000-2100mA!!!! Are there any other good mains charger companies out... show more I bought a duracell one, thinking duracell is a good company... and it barely gives 500mA, sometimes 1000mA output even though it says clearly on it 2100mA.

Are there any other good mains charger companies out there or should I just get that simplistic one from samsung? I kinda dislike it because it has only one single usb output and that's it.
