What is the advantage(s) of the 12 volt models as opposed to the 115 volt models?

It is smaller and more controllable for precision work, especially drilling. In my opinion it does not replace a Dremel when it comes to sanding or grinding.

I do not really know but I have found the Proxxon tools to be of high quality and easy to use. I got mine for precision work, not anything heavy duty.

No. Not really even close. 115 V and 15 amps is over 1000W. Actually, 15 amp number seems way high, but in any event a 50W 12VDC will not operate a small fridge.

First off, you do not need the 12 volt version to control a 12 volt device. You could use the 110VAC version as well since all the device does is open and close relay contacts based on temperature set points. You can route up to 10 amps and 250V through the relay contacts. So, you just run the 12v you wish to switch through the appropriate contact set and then when that temperature is reached the relay contacts close or open. (heating contacts close when a low set point is reached and cooling contacts close when a high set point is reached).

Difference is cost and the XRP I believe gives you extra run time. As for the swapping of 18V's they have worked for me on the tools I have i.e. brad nailer and hand vac. Hope this helps.

The biggest difference I noticed immediately was the way it shifted so much more smoothly.. When it comes to power, I didn't really notice too big a difference to justify that being the main reason to buy. Granted you might running 35's as I was only running 31's

I can't find any data on how powerful the motors are in either of these models. Everyone says they are powerful, but what watts are the motors for each?

I've never had a 12 volt so can't answer your question. It works well for picking up crumbs in the kitchen and family room. Also does lift the nap on carpet. I'm very happy with mine.

I would consider getting the larger ones (the 15' 2000W versions) as they thump harder which is good for outdoor events. I usually use the 12's for smaller indoor events. For the extra few dollars (around $50 I think), I think the larger ones are a better value. I probably wouldn't try to play them in the rain though of course. Hope this helps.

The 220 has Two max speeds (400 & 1400 rpm) while the 120 has One max speed (650 rpm.) Also, torque is 310 vs 115 inch/lbs. The B&D; site really sucks, http://www.blackanddecker.com/allproducts/20-volt-drills.aspx

115-230 VAC is a selection, not a range. So if you select 115 VAC then you have selected the correct output for this inverter as it is a nominal 120 VAC inverter. With a range between 7.5 amps and 15 amps being drawn by the compressor, the inverter is just a bit shy of what you require. Another big problem will be the stoutness of the battery you are using. From a static 12 VDC source (stand alone battery), converting it to 120 VAC, drawing 15 amps, the power used would be 1,800 watts. That is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. From an active 14.5 VDC source (a 12 Volt battery driven by a alternator), converting it to 120 VAC and drawing 15 amps, the power used would be 1,740 watts. Again, that is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. But here is the catch, an AC inverter is never 100% efficient, so the calculations stated above are actually worse. Could be 20% off or more 'off' due to inefficiency. Technically, you could run your compressor for a few moments without damage to the inverter, but this inverter would not be the proper selection for your work load. I would select something in the 2,400 watt range for the continuous power required that you seek. This would give you 20 amps minus 20% inefficiency giving you 16 amps of reliable current. So 2,500 watts, with the ability to surge to 5,000 watts momentarily (allowing a 100% overage of current drawn on start up for the motor of the compressor) should fit your bill. All units will be very happy with each other (provided you have a robust battery, or battery bank). An "8D" battery would serve you well (but pretty heavy at 161 lbs each). Do not forget "voltage drop" that happens, and make sure you use HEAVY cables to the battery; perhaps 2/0 pure copper (not copper clad) cables. This will keep your input high. It is worth the expense (and you only buy them once).

I don't believe there are any differences in these models.The only known differentiator would be when you purchase XPS12 with core i7 4650 ModelThat one has Intel HD 5000 graphics

Runs on standard 115V household current. I have two, and haven't noticed a difference in my monthly bill since I got them.

I'm very satisfied with the 20V version, use it mostly for my DIY projects orotund the house. I just completed a major renovation with an addition the my home, these tools held up well, plenty of torque for what I needed. Never used 18V version so cannot compare. Hope this helps

The difference is the voltage coming into the inverter. The question you need to consider is what is the voltage of the system I am wanting to invert to 120? Most cars & trucks run on 12 volt. I purchased the 24 volt for my solar panels because the system was set up as a 24 volt system.

Hi. the difference is that the 1575 model has the diamond shape pitcher. I don't think that there is much difference with the wattage. thanks

The quiet edition draws 0.08A which at 12 volts is 0.96W. The high performance edition draws 0.18A which at 12 volts is 2.16W. Amps x Volts = Watts

Superior! I can charge the battery and three months later it will have full charge, unlike the 18V. The 20V last longer, jobs that I did with the 18V, I needed three fully charged batteries to complete; with the 20V, one. Plus, it is a lot lighter.
