Samsung j5 goes in and out of charging

[Android Central Question]

I cannot find the original cord my Samsung j5 came with but several us cords ive tried using keep going in and out of charging and will not keep a solid charge unless I sit and hold the cord in a specific position. What gives and is there a cheap fix for this at all????

The USB port may be dirty or damaged, or something else may need repair.
