Just because a charger says "2.0A" on it doesn't mean that it will ram 2 amperes down the throat of anything you plug it into. It means that it will supply up to 2 amperes if demanded.

The 5.3V is higher than usual and just outside the 4.4V-5.25V tolerance of a USB 2.0 port. Let's also not forget that there is no doubt a tolerance for the 5.3V written on the charger, so you could potentially be pumping even more than that into the Prime. Bad idea!

No fast charger will go into fast charge mode unless there has been a successful negotiation between it and the device wanting the fast charge. Your Samsung tablet knows how to ask the charger for more juice, the HP Prime doesn't, or certainly shouldn't!
