This was so cheap (I thought it must be a pricing error), so I ordered 5 of them:
Amazon.com: Crazyondigital High Capacity Dual USB 2.1A Home Travel?
Its a Dual USB 2.1A wall charger. The one that comes with the Evo is a single USB 1.0A wall charger.
Is that too strong for the evo? I want something that will let me use the phone (gps, calls, etc) and charge at the same time. The generic one I have now loses power when I'm charging and using (more slowly than i normally would but still down)
