Can charging port be repaired on an iPad. 2

The iPad2 is obsolete - as such, Apple does not provide any hardware or repair support for such an old device.

You might find an independent repair shop, however, the iPad may be returned with more faults. Instead of wasting time, effort and money on repairing a device that has very limited utility - even when working - you might be better advised to set the money that you might otherwise spend, on an attempted repair, towards a replacement iPad.

Many here would advocate abandoning the iPad2 - it having long ago reached the end of both its actual and technical life.
