Let’s be honest. Most of us have probably put very little thought into the chargers we get for our iPhone. If it plugs in and we can connect it to our iPhone, it must be okay, right? Not necessarily. It’s also important to know that not all chargers are the same. Something that may charge your Kindle may not be suitable for your iPhone, or something that charged your iPhone 1st-gen may be very slow when it comes to charging your iPhone 4S.
Ars Technica did some testing to see what worked and what didn’t, or what was slow and what charged faster.
They also used a micro USB adaptor for the iPhone to test it out. All their tests were conducted on an iPhone 4.
Below is a chart put together by Ars:
Kind of cool. Your MacBook Air will charge your iPhone 4 about as fast as RIM’s standard BlackBerry wall charger.
You can read more detail about the chargers and charging times at Ars. It’s an interesting look at how now all chargers are created equal.
The iPad, on the other hand, seemed to have it’s own set of rules while charging. We personally never had issues, but some users did depending on their setup. There was also an adapter released for the device that made it easier to charge via USB.
