I know this speeds up the charge time but is there any downside like diminished battery health?

I ready on here that the iPad charger would provide rapid charging and I am looking for someone in the know to tell me if this OK or should be avoided?

Others will swear that the phone will not charge a bit faster using an iPad charger. I think it does but only marginally faster at best!

Been charging all my devices: iPhone 6, touch, and both iPad Air with the same iPad charger and no harm has ever come to my batteries.

Well for the base charger, charges my phone in about hour and 30 mins. When using the ipad charger its significantly less......Takes about an hour.

I might retest just to make sure tho.

I feel the same. I charge my iPhone 6 at work with a 10w iPad brick and it charges faster for me. I did the same with my iPhone 5 at work and had zero issues.

nah, it does. I guess i'm lucky?
It really doesn't.

All iPhones (bar the 6 & the 6 Plus) are to designed only to draw 5W from whatever charger is attached.

So, regardless of whether you have an iPhone 5W charger or an iPad 12 charger connected, your iPhone 5 can only draw 5W from it.

what about using an iFrogz 2.1amp lightning to usb? no joke, it charges in double time.

then I have a magic charger. :cool:
That's right.

It's magic because it makes you think it's charging faster because it has bigger numbers on the label. ;)

Remember-your iPhone was designed and built to only draw 5W.

It doesn't matter one little bit what capacity charger is plugged in, it only ever asks for and accepts 5W.

Lower current charging is always preferred. Generates less heat this way. But difference between 0.5, 1 and 2 amps isn't going to cause problems for the battery in the long run. It's that kickstarter device that claims to fully charge a fully drained battery in 15 minutes that will fry your battery in due time.

How could the kickstarter charger fry your battery if the phone regulates the charging!

My iPod charger is also MAGIC!:p

Even if it does charge faster (not here to debate that) it's still not a "rapid charge" like other companies market.

If it somehow overrides the charging circuitry and forces 5-10 amps into the device, it will damage it beyond its designed limitations.

Sshhhhhhh-let them think that their iPhone charges faster.

If it makes them happy, who are we to spoil that? ;)
