Iphone 6 charger this accessory may not be supported?

My iPhone 6 will charge successfully for quite a while before IIm told "this accessory may not be supported" and it becomes disconnected. I have used the official charger that it came with, as well as replacement ones bought online, and have plugged it into my laptop, the wall, and the car. This seems to happen regularly.

The weirdest part is that the same stuff happened with my old iPhone 4. Does Apple just make ridiculously crappy accessories or is there something IIm doing wrong?

This usually happens with chargers bought online. If ot happens with the oroginal then it might be fake as we. If you bought the iphone at apple shop or some otther kind of electronics shop that sells 100% real phones the go to them and ask to give you a new charger. If you bought it online then just go to a electronics shop and buy the real charger. It usualy costs 14€ .
