what is the charging specs on the iphone 4s and the ipad 2?  I have a the philips DLA 95543/10 auto charger and the specs on it are :

 

input       10.5-18v DC       ( I know what this means )

output     5.0v DC 500mA  ( i know what this means too)

power     2.5w                    (  this is what i am concerned about )

 

everyhting I can find talks about 2.1w.  So is the charger I have going to blow up my iphone and ipad?  the phone gets hot while chaging with it. 

THanks in advance


iPhone 4S, iOS 5.1.1

If you are referring to how many watts, you would need 5 watts (5.0 volts * 1 amp) for an iPhone and 10.2 watts (5 volts * 2.1 amps) for an iPad.  In the case of the iPad, 10 watts should work since the Apple charger for the iPad is rated at 10 watts.  I would suggest buy a charger that says it's compatible with an iPhone or iPad depending on your needs.

Charging Specs:

 

iPhone - 5.0V DC, 1A

iPad - 5.0V DC, 2.1A

 

Watt = Volt*Amp, so 5.0V * 500mA = 2.5W

 

Although according to what I've read, 5V DC, 500mA may charge your iPhone (slower than 1A), I would recommend 1A for your iPhone and 2.1A for your iPad.  Also note that I have used an iPad charger (2.1A) to charge my iPhone with no problems.

    So 2.5 is too much? And I need to buy a charger.
