Can I charge iPhone with iPad charger? (1A vs 2.1 A)?

A(Amps) — amperage characteristic of the consumer and not the source. Source-this is the maximum allowable current. If the controller is the iPhone able to properly control the charge current though it 100A charger plug nothing happens, charged as usual.

it just charges faster. and the rest just seems

.

Possible, but from the old USB port I have a Mac 2006 not to charge.

Lay in the car charging for iPhone from Griffin when it mounts the iPad says "not charging" but if you leave for a few hours (e.g. in traffic) then the iPad is slowly but surely charging)

Don't know how with the iPhone, but battery iPod Video crazy from it. Two days pumped native charger.

After buying iPhone4 took native IOS charging to work, the house was charging from iPad1 to charge both devices. So today the phone just refuses to work without the cord just goes out through 0.5-3 minutes after pulling out (charge 100%)... to Restore the firmware I tried, did not help. I sin on the power controller, which is very happy =( And I also thought that nothing will happen.
