    I'd like to be able to actually charge my phone while using it as a satnav. Will I need a more expensive 2.1A charger or will a cheaper 1A one still charge the phone?

    1A should do you for the iPhone. This is what the stock wall charger provides. More amps would be needed for the iPad.

    Thanks. I just want to be sure as I remember reading somewhere that people find their phone charges very slowly if at all while using as satnav.
