Don't have one already, though I bought one during the sale too.
I also didn't find the info in a cursory glance in the usual places, but some math helps here...
Specs show the tablet has a 5000mAh battery, and that it can fully charge in 5 hours.
"mah", for the uninitiated, is "milliamp-hours, so 5000mAh is the same as 5Ah (amp hours).
If the charger than fill a 5Ah battery in 5 hours, it's charging at 1A, plus any inefficiencies in the charger block, and the fact that the charge time probably takes into account the device being on at the time.
*ESTIMATES BASED ON ASSUMPTIONS AND PERHAPS FAULTY LOGIC*
So, let's say that the power block is only 50% efficient, and that you need to double the power to charge while it's on. 4A, let's call it 5, and it likely charges that built-in Li-Ion cell at around 4.2-5V. You're looking at around 25W
I'd make sure your inverter was good for several amps, but I'd imagine that nearly anything from rat-shack or the like would suffice. Most people buying 3-prong inverters are looking to power laptops with them, and this is certainly going to take up less juice than that.
