Q: Can use ipad charger to charge iphone?

Anecdotal evidence does not trump science.

Bull.

Zero "evidence", 100% bull.

I posted the real evidence from experiments I did a couple of months ago. I charged an iPhone with no apps running (did this by running the battery all the way down, which kills all processes) using a 12W power source and a 5 W power source. The charging time was the same (within about 15 minutes) and the temperature of the phone was the same for both (measured with a laser temperature gauge). This is what I expected, as I have used a 12 W power source with my 4S for as long as I've had it (18 months) with no negative side effects.

When I next get time I will sacrifice a USB cable and measure the current going into the phone with each power source.

I knew I should have put quotes around the word evidence!

I'm going to sacrifice my iphone and test the current regulator in it to seee... :)

I found this video on YouTube:

Hopefully it will help all the people to understand how the charging process work!

Thanks; that should be convincing to anyone.

I'm going to make my own charger...

• Now it is confirmed* that It is 100% safe to use an iPad Charger (12W) or (10W) to charge an iPhone (5, 4S, 4 3GS, 3G, and 2G) and iPods (all versions).
• But there is no benefit  or disadvantage on doing that b/c it wont charge your iPhone faster or damage your device battery
• Can be used as a replacment only.
• iPhone uses  1 amp current to charge the battery not more than that so there is no over heating issues
• iPad charger can provide higher power (up to 12W) if needed (iphone needs only one amp or 5W)
• I hope this clarifies things a little bit.

* I had a long discussion with a graduate student (Electrical and Material Science Engineerin with thesis on battery life)

But the iPhone does not withdraw 2.1 Amps from the iPad charger either, it'd draw 1 Amp. Web it will may charge faster if its we are using the iPhone, because it will be draining the battery, but thanks to the extra amps from the iPad charger it will keep charging at 1 Amp rate.

Just an FYI about assuming a company's lawyers have reviewed everything on a company's website; while it would be wonderful if clients did have their lawyers review everything that could get them in trouble, they don't.   The lawyers probably drafted their liability disclaimers, anything contractual....but I seriously doubt they review the product pages much at all.

Given it is Apple I would not be surprised at all if everything regarding specifications and product usage is reviewed by attorneys.

No offence to anyone. But, I keep getting all these notifications from this forum. Could we PLEASE STOP THE DISCUSSION!!!!

Isn't the issue been resolved? You should be either dumb or ******** to post below this comment.

Again, I am sorry if I am hurting any feelings here but, c'mon lets end this.

Thank you and Regards,

Ajay

No offence to you, but up on the top right of this surprisingly long thread it says "Stop Email Notifications". Click on it and you won't receive any more notifications.

I know. I need the notifications to see if anyone finds anything wierd with the charging itself not discuss about how Apple can buy lawyers and make their own rules.

The question was:

Can use ipad charger to charge iphone?

Please correct me if I am wrong and this will be my last post on this thread.

Thanks,

Ajay
