I would strongly recommend against it for a couple of reasons.
First, as is stated in the product descriptions which you linked "Caution:
(1) This voltage converter may not work properly [...] some items with heating element such as coffeemakers, espresso/capuccino makers, percolators, heating pads, toasters, toaster ovens, rice cookers, tea kettles, hot plates, cloth irons, steamers etc."
...which is exactly what the braumeister is, a large hot plate essentially. So basically these would not be guaranteed to work in the first place.
Furthermore, you would need to buy a unit that is at LEAST 2000W, since that is the power requirement of just the heating element. If they can be used continuously at 80% you are looking at needing a 3000W supply. The money you spend on this unit plus the extra power you would be using might help offset the cost of hiring an electrician to add a 220v circuit and outlet to your residence.
No dryer in your place? No way to perhaps make an extension cord?
