    My wife has an old iPad that she uses for various tasks and doesn't feel the need to upgrade to new hardware. For whatever reason she has a hard time keeping it charged with the old resources. I am trying to find an adapter that will allow her to charge her old iPad with the outputs of the newer chargers like the Lightning or the USB-C chargers that we have around the house.

    Is there such an adapter?

    Hello - first tell us which specific iPad model she owns and from the title, I'm assuming that the old 30-pin power adapter is being used?

    The iPad chargers use 10 or 12 watt power adapters (basically, 5 V x 2 Amps), so that is what you should be using. Have you tried a different charger w/ the iPad or the charger(s) she uses on a different iDevice to determine whether it is defective?

    Finally, depending on the age of the iPad and the number of 'cycles' the battery has seen, the issue may be the battery - if possible, I would suggest testing w/ other chargers and also taking the device to an Apple store (or a reliable authorized Apple dealer) to have the battery tested. Dave :)

    Dave, it's a pretty simple question really... Did you look at the post title? It doesn't really matter what model iPad it is (or if it is even an iPad), I just need an adapter that will carry (charging) current from a female Lightning to a male 30-pin (or the corresponding gender of the USB-C input) to charge a device that is representative of the old iPad configuration. Thanks for your input though.

    It's very possible that the wife will replace her iPad and if that happens my query is moot.

    Apple offers adapters to connect a 30 pin charging cable to the Lightning port on a newer iOS device. As far as iknow an adaptor to connect a lightning cable or a USB-C cable to a device with the 30pin dock connector does not exist, at least as an authorized accessory.

    With the exception of the newest USB-C chargers, all Apple's iOS chargers have standard USB ports. The Lighting cable uses same port on the charger side that the 30-pin cables uses. So, if you want to use a newer charger, just plug the 30-pin cable into it. No need for a fancy adaptor that would only add extra complexity.

    (The excpeption would be the oldest 30-pin cables that came with older iPod (music player) models. These used Firewire ports on the charger and cable.)

    If the problem is the 30-pin cable itself, apple still sells replacements for them; or any Apple approved third party cable should work.

    There is no point in getting the 29W USB-C charger. Charge rate is controled by the iPad's hardware, and 29W exceeds the charging capacity of pretty much every iPad except the newer Pro models. The USB/Lighting 12W chargers should be more than enough

    NOTE: The USB-C 29W charger is for the new Macbooks; though it has been used for quick charing 12.7" iPad Pros, that is not it's intended puprose.

    The reason that the MacBook 29W charger can fast charge the 12.7" iPad Pro is that, unlike the Lightning connector on any other iOS device, the Lightning connector of the 12.7" iPad Pro is USB-C compatible and fast charging requires that USB-C compatibility.

    You guys got it. I want to use the 29W supply to charge the old iPad. Is there any chance that will NOT work (different voltage, overcurrent violation, et al)?

    You'd be wasting your money as the 29W charger will not charge an older iPad any quicker than the charger the iPad originally shipped with. It won't harm the iPad , it just won't charge any faster. The only iPad that supports quick charging with the 29W charger is the 12.7" iPad Pro.

    If your wife is having trouble keeping the old iPad charged maybe the battery has worn out and needs replacement.

    Not that I don't believe you, but why do you say it won't charge faster? It's got to have a higher current output rating since it has a higher wattage (and assuming that the output is 5v like all iDevices), 29W/5V=5.8A (less any conversion losses).

    It won't charge an older iPad any faster because the charging port on the iPad is not USB-C compstible, unlike the charging port on the 12.7" iPad Pro which is USB-C compatible. The power output of the 29W charger, when connected to a USB-C compatible device with the proper USB-C cable, is 14.5 volts. When connected to a device that is not USB-C compatible, the power output is just over 5 volts. It's the higher voltage and the proper charging circuitry in the USB-C compatible device which allows for faster charging rates.
