Can I use any brand power adapter in my iPhone?

As long as it’s a quality, branded adaptor you should be fine.

You phone will only draw as much electrical power as it needs from the adaptor …

… the adaptor does NOT force it’s full output into the phone.

Remember … the adaptor and cable is the only thing between potentially damaging mains AC voltage, and your pricy mobile device. Saving a few dollars w/ a cheap knockoff could cost you dearly.

Hey there,

Yes, you can use it, but make sure it is one of Apple's original chargers.
