What's the relationship between power amp vs volts vs watts??, I'd like to know the power of the vacuum, and do some comparisons among them, because for me the power is one of the most important features, but some models give you amps, others volts, others watts! so if anybody can give a straight answer I'd appreciate it. - Thanks.

On the the Dirt Devil Scorpion the sweeper shows 120 volts-60 hz and 7 amps.I find this hand sweeper has a lot of power.I use it more than I do my large sweeper.It is easy to handle and I use to get behind things.Also works great in the car as I live in Florida and go to the beach a lot so have sand in my car.Really picks that up.Hope this helps you as I not real good on volts and amps but before I bought this sweeper I checked what my old one had.This has more I have used Dirt devil sweepers for close to 10 years.

Watts = Amps x VoltsAll residential Vacs run on 120 Volts.Power used (watts) does not translate into the vacuuming power necessarily. I rely more upon practical considerations. The way the motor was constructed, the ducting, filtering of dust and dirt, all impact efficiency. One way to evaluate the power of a hand vac is the torque you feel in the hand that holds it when you first turn it on. The Scorpion's torque is massive for a hand vac. No battery driven vac can equal it.

Don't really know the difference, but this had got to be the most powerful hand vac I've ever owned. Super strong suction. It's corded, not battery

I'd recommend keeping the central vacuum and getting a better power nozzle, no traditional vacuum can beat the power and versatility of a central vacuum. You also may want to upgrade your main unit, the airflow/air-watts the better.

They're both pretty comparable as far as volume goes. But you have to realize you're talking about solid state wattage here, which is very different from Tube wattage. There's really not going to be much difference in overall volume from a 75w and 100w solid state amp. But when you say "as loud as a 75W amp should be" that doesn't quite make sense. A 75w tube amp will blow the doors off your house. You would never need to turn it past 1 or 2 and you'd never hit that sweet spot with preamp breakup. One brand's 75w solid state amp can be louder than another. It's not quite as uniform as to how the wattage is used in solid state amps. If you're looking for something loud enough to play with a band, this would be loud enough for most gigs. If you need anything louder, you'd most likely be playing somewhere that has a PA system, so they can just mic it up for you.

We used it for a laptop that only draws 1.5 amp. Worked great for that. I would look on the label of the vacuum and it should tell you how many watts and amps it uses. You need to leave car running because it will drain your battery quik. Hope this helps

Hi Paul! Thanks for reaching out! The XPA-2 outputs 300 watts per channel into 8 ohms and 500 watts into 4 ohms. Please let us know if you have any other questions! Thanks!

You shouldn't worry about using thousandths of an amp in current flow...people often worry about a slight trickle of current without addressing what item draws hundreds of times more power...learn basic electricity.

Tuff q. Cause there's many variables u have to look at like I got mine wired for 2. ohm with 0 Guage and got 2 amps a kicker 1100 and a weird brand that's 2500 but both are 2 ohm stable I wish I could have 6000 watts to match my subs but my car is a Volvo and not much room to upgrade my alinator to be able to pull 6000 watts bUT deff. Do 0 Guage so u don't ever have to upgrade u r wiring anymore that's your I did it... if u want shoot me a call or text be a lot easier to explain than a huge paragraph or a lot of info .. 5098287627

I ordered it, used it once, returned it. Was the worst design of a vacuum ever! Sorry, can't answer your concern about voltage. I would suggest that you either return it if possible or give to charity.

Voltage is not measured in Watts.....5 volts. It draws 0.4 amp or 400 mili Amp most likely. (it also makes sense). But why are you concern about power input??

900 watts = 120 volts x 7.5 amps so yes. However in basic theory because a vacuum cleaner has a motor it probably will want to draw more amps than 7.5 amps at startup. Remember it will also have to be directly connected to the battery. Personally I would go with at least a 1100 watt converter, but I am talking theory here and I have not done what you are asking (used a 5am vacuum cleaner with mine).

http://www.convertunits.com/from/mA/to/watt/voltHere is the conversion I found. The product only has marked 600 mA (milliamps). I ran the conversions and 600 mA came out to 0.6.watts. On the backside the info listed is:600 mAInput: 100/120VAC. 50/60Hz 0.3AmzxVout DC: 3, 4.5, 6, 7.5, 9, 12On the front in has a voltage selector that can be moved to any of the following:12V, 9V, 7.5V, 6V, 4.5V, 3VIt also has a selector on the side that goes from (+) to (-) for me it it toward the (+).I use mine for an old personal single CD player. I did not change any settings, I put on the size adapter I needed, plugged it in and it works great for me.I do not know what all this information means but I hope it help answer your question. http://www.convertunits.com/from/mA/to/watt/voltHere is the conversion I found.

OK, this is how I think of it. Watts=amps x volts. So from their description, 7 watts = amps x 12 volts. This makes 7 / 12 = amps putting it at .58 amps. I checked the back of the panel. It says 467 mA. Google says 467 milliamperes = 0.467 amperes. Kinda close? Hope this helps.

Every tool manufacturer has found a way to exaggerate their power ratings in order to make their products more marketable. Those 120v shop vacs that are claiming an output of 6.5 HP is case in point. They get away with it by calling it "peak" horsepower. I believe they calculate peak HP by factoring in the start up amps that it takes to get the motor going, not the running amps. Startup amps can be 3 to 4 times the normal running amps. Yes, startup amps only surge for a second or two at most, but again it's a marketing ploy.

It provides more but the unit you plug in only draws what it needs. So lets say you have a phone that draws 2 amps and 10 watts. The unit can supply up to 3.5 amps and 15 watts but the device you just plugged in only draws the 2a and 10w it needs, its not forcing it to take 3.5 amps and 15 watts. Generally you can only damage something like this if you give it the wrong voltage supply.

While there is a relationship between power consumed and heat I'm not sure of your question. I use it in an enclosed space and it generates no more heat than any other tuner/amp of equivalent size and power. It also has an eco mode that uses less power although sound performance is degraded so that's not an option for me.

"12V" stands for 12 Volts. "V Amp" usually stands for Watts (Volts times Amps equals Watts) Watts is a power used value (Such as a 60 Watt light bulb). So, "12V Amp" would mean 12 Watts. The entire text around the "12V Amp rating" would be necessary in determining the full meaning.

Can't help you with the wattage, but I can tell you it's very powerful and does an excellent job of vacuuming the car........even picks up dog hairs. Just start your vehicle, plug into the 12V outlet, and you're off to the races. We are 100% pleased with this vacuum.
