Need charger for an IPAD 4TH GENERATION MODEL A1458

If by charger, you mean the block that plugs into a wall socket, any USB charger (12 watts or grater) will work. Apple no longer sells those, but you can buy an Apple USB charger from Amazon for instance.

If you mean the cable that plugs into the iPad, then that is a Lightning to USB cable and Apple still sells those:

That model of iPad shipped with a 12 watt charge cube, so any charge cube with the appropriate USB connection and a minimum of 12 watts should be fine. Those can be found at most electronics or department stores.

Then you a buy it from the Apple link provided previously.
