How does that work: 3500W on 115V = 15A? New laws of physics? Should be 30A. What I am missing?

Your math is impeccable. But the thing does work on a 110/120 Volt circuit. It is a crude device, as you might expect, but did do what I wanted. I don't know how many holes it has the durability to drill. Be careful buying the Chinese diamond faced core drill bits.

I'm glad you brought that up. I can't explain all that mumbo jumbo. Perhaps it had a little to do with the translation from Chinese to English. Who knows, but 15A works. What I can say is it does the job. That's all I care about. Buy it, don't buy it. Either way it has served me well. The machine has paid for itself many times over.

Don't buy it mine burnt out in one week! Maybe that was why - I'm so busy it's sitting in a heap on the floor I don't trust them to replace it - so it's not worth paying the shipping Graham

My understanding is these are maximum wattage and minimum operating voltage and current.

don't know the answer to your question but the drill surely does work well!!

I bought the very same setup but had not hooked it up till I saw your question. My 12 volt power supply is only good to 5 amps but the converter boosted the voltage up to 33 volts no problem and the light is blinding at 60+ watts. I didn't have a heat sink on the 100 watt LED so I could only run it a few seconds. THe buck converter has some good heat sinks on it, your biggest issue will be to cool the LED. I have used a CPU cooling fan and run my other 100 watt LED as an adjustable lab bench light maxing out at a de-rated 30 Watts, it works amazingly well. You might want to put a small fan on the boost converter as well since 10 watts of dissipated power does add up. I bought the very same setup but had not hooked it up till I saw your question.

rated for 3.2-3.4v and 20 mA. P(W) = V(V) I(A) 20mA = .02 A So 3.4v x .02A = .068 W hope that helps

Nice use of Watt's Law, but you can't calculate the input draw based on the output power. 6000w is calculated using the voltage of its internal power supply not your 120vac wall outlet. So 6000w output does NOT equal a 50a input draw.

Power = Volts x Amps... So 300 is more than enough. Personally I bought the 500 Watt version because I use it for many things

Hello! My numbers are the same for output voltage. It reads: 5.0 V = 2.0 A. It's a great product!

Check those specs again... where did you get 15amp from? 115v x 15amp = 1725watts. A 50w panel will not power a 1725watt appliance. Your best bet is to buy a Kill-a-Watt meter from amazon. That will provide you with accurate usage specs.

I(A) = P(W) / V(V)orWatts = Amps * Volts30 watts = 2.5 amps * 12 voltsThe power supply is rated at 30 watts, and the voltage is 12 volts, which comes out to 2.5 amps. So the answer is one 2.5 amp string per power-supply.

It says 35 watts, but I'd like to know how that transfers to amp draw per hour.

Hey man, the best advice I can give is go to pcpicker dot com and "build" your computer within the website. It should tell ya if 300W is enough. :) That is what I did when building my computer!

that's what I am doing - here's what i am finding...the control item (using a kill-a-watt) is still drawing .005 amps when everything else is off...i know this is practically negligible and in the scheme of things it's not really gonna matter money wise, just led me to the question that if the most least power consumption device (i.e. -0-) was the control item there would be absolutely no draw whatsoever. Thank you for your replies and if I am completely off base, please let me know

I hooked mine up to my regular household voltage----120V. (although yours may be 110, 115 or 120). When connecting it to an existing circuit, make sure the total expected wattage load won't exceed your circuit amperage multiplied by the volts. Example: On a 15 Amp circuit, with 120 volts, I have a capacity of 1800 watts. If I'm running my Waste King at 450 Watts (4.5 Amps) while my standard fridge is powering up at 350 watts , and my toaster or microwave are running at 1100 watts, and my lights are on, I'm likely to flip my breaker. That's why the electrical load of most kitchens today are split over two or more circuits.

OHM's Law...V=IR Therefor 12volts=0.005X2400 The power (or watts) will be 0.06watts. If you want proof try this link and put in the variables http://www.ohmslawcalculator.com/ohms-law-calculator Kind regards, John.

Not certain. What I will say though, is that 300W is not what it used to be......if you get my meaning.

Hi! Sorry, it took me this long to response. I had to go and check it since I already stored my fan in the basement. But it read at the bottom 120 volts. I hope this helps or you can.probably contact the seller or manufacturer.

Just barely. The sticker on it said the max amperage is 17.4 amps x 115 volts = 2001watts. I would go with a larger unit so you don't burn something out. I run with a 3500 and it does good but you have to be carfull not to run any other high power appliance with it.

I do t know where you see that? It must be a typo. I would guess it means 115v.
