Charging an iPhone 3G with an iPad Power Adapter?

Hi, same here.

We finally got the iPad in the Netherlands last weekend and I was using the included Pad 10W USB Power Adapter to charge the iPad and iPhones.

The problem occurred when my son was juicing his iPhone 3G with the iPad 10W USB Power Adapter.

- When charging the iPhone 3G with the iPad adapter, the icon shows it is charging but there is no progression in %. (only after rebooting the iPhone 3G.)

- I was already worried that his battery was defect, also because the battery at a sudden was a 20%. Using the iPod USB Power Adapter with the iPhone 3G solved the charging problem.

Using the Pad 10W USB Power Adapter with the iPhone 3GS shows no problem.

So this is an interesting case as the problem seems exclusively related to the iPhone 3G.

Apple please look at this !

The iPad charger won't charge the iPhone but the iPhone charger will charge the iPad.

The iPad charger should work with the iPhone.

"It also charges iPhone and all iPod models with a dock connector."

Are you using a genuine Apple cable to connect to the iPhone?

The iPad charger doesn't charge the 3G with the Apple approved cable.

What is the source of your data? My iPad charger charges my 16GB iPhone 3G without any problems at all and I've used it with cables from my local 'The Mac Store' (it is a third party cable but I don't know their source), from Apple, and from Griffin.

Same here. iPad charger charged my iPod touch just fine, but doesn't seen to work with my iPhone 3G. Battery indicator has the little lightning bolt symbol for a few seconds, then changes to the mains symbol. Was plugged in for a couple of hours without any increase in battery level whatsoever.

Hi Stefan,

same issue here. Ipad adapter does not charge either of the two iPhone 3s we have in our household. A real bummer. Conversely, the iPhone charger does charge the iPad ableit slowly. So I wonder what the deal is as it does not seem to be affecting all people???

Hm, cross-check this thread:

it is about the same issue...
The IPhone becomes charged, but the status is not displayed correctly. It is displayed, after rebooting the iPhone 3G

Very odd. The higher capacity iPad adapter should have no trouble charging the iPhone.

I'm running a 3G and it charges just fine with either the iPhone or iPad charger. Just checked it. My iPhone was down to about 60% charge, so I noted where the green bar was on the locked screen, and put a yellow stickie there to ensure I knew exactly where it was before I plugged it into the iPad charger.

5 minutes later it's up to about 90% (visually, I'm not looking at numbers here). No reason to expect that it won't be full in a few more minutes.

In Stefan's original post, you can see from his signature that he's running iOS4.0.1. fzahn linked to another post where the problem appeared after an upgrade to iOS4.

On the other hand, crh24 lists his (her?) iPhone as iOS4, and says that she (he?) has no problems.

*crh24, is your phone running 4.0, 4.0.1 or 4.0.2?*

For the record, I'm running 3.1.3, and the charging works (and is properly displayed).

Just following up.

Yes, after a few more minutes, the iPhone 3G (iOS 3.1.3) displayed a full charge - without a reboot.
