Charging issue

If you tested the power adapters, then test different cables. If you still experience a problem, you need to contact Apple Support to have the device examined by them. Use the Get Support link at the top of the page.

You did not define what you meant by trouble, so those steps are the best I can provide.

We are all special, however as far as your charging issue, what do you mean by trouble? Since it is occurring on more than one device, I would check the power adapter, cable, or both. If this is a power adapter that plugs into the wall, check another outlet to make sure there is no trouble with that.
