Does anyone here have a reliable source for a 10W USB charger that can be used with an Ipad 2?

I bought a supposed 10W charger two pack off Meritline a while back and one charger produced such dirty current it froze the touch screen on the ipad whenever it was connected. The second charger died after a week of use.

I'm looking for a simple wall charger that's compatible with the Ipad and will charge it in the same amount of time as the Apple branded charger. I already have two spare 6 foot charging cables now so I don't necessarily need a cable to come with the charger.

If I had known it would be so difficult to buy reliable 3rd party accessories I would have just shelled out for the ones sold by Apple directly.
