Now with this knowledge toucan be assured that the battery will not be damaged if charged with an iPad adapter. Now the question remains, why Apple doesn’t ship 12W charger with iPhone if it is compatible.
Secondly, 12 W charger do have an insignificant amount of negative impact on battery’s life, so they want to play it safe. From the study by Stanford University and claims by prominent engineers, we can simply deduce that it is highly safe to use iPad chargers to charge any of your iPhones.
Just connect your device to the power adapter with the USB to Lightning cable, 30-pin to USB cable, or Apple Watch charger that came with your device. Apple explicitly approves of using its chargers across all devices that accept Lightning cables.

According to Steve Sandler, founder and chief technical officer of the electronics analysis company AEI Systems, modern battery-powered electronics have a lot of complexity between the charger and the battery, including battery-charging circuits within the device and battery-protection circuits in the lithium-ion battery itself.
These circuits are designed to manage the flow of electricity to the battery, and if the circuits inside the iPhone were designed to tolerate 1 amp, but are routinely exposed to 2 amps, that could stress the system over time. Our advice: Since Apple claims compatibility between the iPad charger and iPhone, pay for AppleCare (it’s worth it for lots of reasons) and charge your devices with the biggest wall chargers you have.
If your battery degrades severely after the first year, make Apple give you a new one. This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.

For the sake of argument, let's ignore the voltage because it's not really relevant to this discussion (seeing as all the chargers give out 5V). When using a 5W power supply to charge an iPhone, you will be drawing the maximum current available (1A).
Two things limit the charging time of your device: If you are using the EXACT right charger (same voltage and rampage as the device) then it will draw the maximum amps/watts available.
Your device will take a LOT longer to charge. Experiment for yourself: plug a new iPad 4 into an old USB 1.0 or 2.0 port overnight and see how much charge you've gained in the morning.
There's nothing wrong with doing this as a once-off, for emergencies, or on an irregular basis, but you will do progressive damage to your device if you keep doing this. Using a higher-rated power supply on an iPhone won't damage it or charge it any faster.
Apple 12W USB Power Adapter iPhones supported, iPods supported: Same as for 5W iPods additional: Touch 1st gen, NATO 1st gen, A lot more of the classic models iPads supported: mini, 1st-4th generation Note : As others have suggested here, it may (seem to) work, but if you experience any problems, like a burnt out charger and/or device, having used an unsupported combination is sure to put a dent in the warranty plan for the damaged unit.
This leads the smart sensors in the cells to go haywire and not know when it is fully charged or not. This often leads to people seeing their battery charge capacity lessen much faster over time.
Toucan find an Apple Retailer in your area to get pricing on a new Power Adapter. It's not advisable to use iPhone charger for iPad since it chunks out only half the required power.
Even though it charges the iPad very slowly, overtime this might damage the battery. I use express charging very rarely (only when I'm in a hurry) otherwise always use my iPhone charger or PC.

Hi, I have charged my touch 4G with my ipadcharger (output of max 10V). I have also given the charger to my mate for his iPhone 4, and it works fine.
If you are using Windows PC, then there is a program made by ASUS, which allows you to charge the iPad via USB but is very slow. I have a 2A Incas car/wall charger for iPad, iPhone, and iPod.
You may find the iPad compatible charger will charge the iPhone much faster than that of a lower amperage. Thanks everybody, and thanks 88_king, pls let me know the USB charger program.
Iphone 4 small charger can change iPad, BUT the charger does get a lot hotter than usual and will die a lot faster than it should (confirmed: 2 separate iPhone 4 chargers chagrin different iPads died with in 3 months of use) The iPad charger on the other hand is fully compatible with iPhones and will reduce the Wattage when the iPhone is plugged in. iPhone and iPod: Using the iPad 10WUSB Power Adapter, http://support.apple.com/kb/HT4327 While designed for use with the iPad, toucan use the iPad 10W USB Power Adapter to charge all iPhone and iPod models.
When charging an iPhone 3G with a 10W USB Power Adapter, you may notice that the battery indicator does not increase. I mistakenly plugged my iPad charger into my iPhone last night and vice versa.
This morning I lost 62% of my iPhones charge in 2 hours doing nothing other than answering a text message. Clearly this IS harmful to the battery and I would recommend that no one charges their phone in this manner.
Alternatively I have lost 1% of the iPad charge while writing this response, so also not normal. MMM I'm not going to ask how you managed sticking an USB male port in the iPhone.
