Can you get to 220V power somehow? A clothes dryer in the next room? I used to unplug and plug in a table saw from one in a rental.
If your goal is to collect the visible dust that falls to the floor quickly then that DC would probably do, as long as you know you must wear a dust mask while you are in the shop, both during and for hours after you stop making dust. The reason being the most harmful dust to you is not visible and hangs in the air for many hours. Also because as already mentioned, the 2.5 micron bag is not good enough to trap the fine dust. The invisible dust is under 10 micron and the finer the dust, the deeper into your lungs it goes. So aim for a 2 hp with cartridge as a minimum. If you are going to slap in a add on cyclone to keep the filters clean then 3 HP with a 13"+ impeller is minimum. Cyclones have resistance/drag to the airflow so you need to overcome that with bigger DC's.
DC CFM claims are usually about 2 times what they will actually deliver in the real world. They test them with no ducting or bags attached and in the centre of the airstream where it is the highest. Ideally you want 1,000 CFM at the tool
4" pipe only flows about 450 cfm at the most, usually less and flex hose even less. 6" flows 1250 cfm at its best. You need that extra flow to capture the fine dust. A 1 1/2 hp DC isn't powerful enough to use 6". Flex hose has 2 to 3 times the flow resistance that a smooth pipe does. So 20' of hose is equal to 40' to 60' of duct.
Bill Pentz has an in depth site on dust collection that is very informative. It is long and he repeats himself but that is to inform people that cherry pick certain subjects.

The best forum on dust collection is Australian and well worth reading too.
