Any idea on how to charge the P7000 faster?

I don't know about you guys, but charging my P7000 is a struggle. Literally, it takes on average 6 hours to charge from 0 to 100% with the stock charger. I tried many different chargers (Samsung 2.0A, Aukey Quick Charger, Asus VivoTab 8 Charger) and they are all amazingly slow (usually even slower than the stock one).

Could anyone figure out how to charge this phone faster? It drives me crazy to take this long to charge!!!

Thank you.
