Does this measure watts in real time? I want to see the max watts when a device starts and watts at steady state, will it do this?

Yes. It does get screwed up after recording for more than 30 days. It also calculates the power factor and displaus actial power generated into an ac load system. If dc should be 100%, so no derating. Eg into a battery chrging system.

It's a static display, and is not giving you a dashboard view. You click it and it cycles though the metrics of measures. Otherwise it is giving you the current measure of what metric you have it on.

Unfortunately, it will not. It will give a lot of real time measurements and do a watt-hour summary for and time starting at the time it is plugged in but this probably won't help you. You will get real time current usage if you want to watch your amp draw current as you play with volume and speaker loads.Hope this helps.

Yes, the meter reads from 0 to 150 watts. My rig is just like yours in output and this meter works fine.

No the cadence/speed sensor does not provide power (watt) data. You will need an ant+ compatible power meter.

Yes, it'll read current no matter what's generating it. But what you really need is to put a load on the battery and see how long they last. You can calculate how much power they deliver.

If I understand your question, you could look on the back or the bottom of the device where there is usually a label that lists how much power it uses. Also the transformer/power block that you plug in to charge the device will show how much power it draws. I hope this helps.

No, I think the questioner does mean watts. In applications where using a generator, such as a 2000w generator it is important to know the startup amps/watts so as not to overload the generator capacity. So I would repeat, does anyone know the startup watt draw? Start up amp draw would help as well.

I really can't answer that... that is a large wattage device. My use was to run computer equipment which has been doing very well so far. I'd say check the watt requirements on your equipment and expect it to use more on the startup. Hope this is helpful.

That depends. Appliances with motors can take extra current (or watts) at startup that might be 2 or 3 times the running current. The Kill-a-watts does not really detect that peak turn-on wattage. But you can watch the display and it will update in a second or two and you can roughly how much current (wattage) the appliance takes. But you will need to watch it at startup. For appliances without motors, you can just look at the typical wattage and get a pretty good feel for how much electricity it will require.

I have used it to monitor my refrigerator and it is excelent. From 05 watts to 150. I will try my microwave next but am not sure its maximum. Hope it can handle 1500 watts to test my heaters.

This measures AC power in watts and amps. The Efergy True Power (version) is much more accurate as it calculates power factors to give you more accurate results in watts and watt hours consumed. This unit does not measure amps or volts. If you want to monitor your batteries and their charge status (measure amps, voltage and track amp hours consumed) then you will want something more like Xantrex Link or Link pro, or Trimetric makes a power monitor system that is pretty popular. These devices will monitor your amp draws and keeps track of the amp hours taken from your batteries (much like a gas gauge does on a car). This measures AC power in watts and amps.

I just started testing using a "kill a watt" meter($20) in cleveland. Skies that look like an ad for prozac. 65 watt max so far with 1killowatt hour accumulated over 1 week. My garage roof angle isn't the best(west). More data soon, follow up. Kw is a load measurement, kwhour is accumulated consumption.

It will measure the kWh used by whatever is pluged in to it. It will also aggregate the total kWh used for a period of time. I used it for deciding how big of a ups I need for my nas and router.

I think the question was... will this unit use 44 watts of power no matter the load? ie... will this unit still consume 44 wats if you only have a 5 watt load...My best guess is it will only use what it delivers to the load plus some wasted power in the 120 to 12 volt conversion process as there are no 100% efficient methods of conversion.

The MT-5 will not show how many watts you are getting from your solar panels. The watt of your solar panel you can find it in its instruction.

Mine doesn't. It still provides power until the device stops requesting it. It would waste power. If you want to see the status, just click the button again.

I hope you haven't bought this piece of junk. It doesn't matter how many watts it is. See my review (JG) from 12/31/12. I sent mine back.
