UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.

What size gas generator shoud you use for 55200 watts?
You would need at the minimum a 56 KW generator. In reality you would need a 60KW.
What gauge wire will you need for a 400 watt amp?
To answer this question a voltage needs to be stated. The formula needed to find the amperage is I = W/E. Amps = Watts/Voltage. Once the amperage is found, the proper size conductor to handle that current can be established. Without knowing the amperage on 400 watts a good guess would be a #14 wire. This wire size is good up to 1440 watts at 120 volts.
What size generator would you need to power a 200 amp tig welder?
Generators are rated in watts or kilowatts. The formula for watts is W = Amps x Volts. To size a generator for the welder the voltage of the machine must be stated.
How many watts does a generator need to run a shop vacuum or buffer?
It really depends on the size of the vacuum or buffer. Considering that the typical outlet in a house is (approximately) 115 volts and will handle 15 amps of current, the most the generator would need to be is 115V x 15A or 1725 watts continuous power. You can check the amperage rating on your vacuum or buffer to get a more accurate answer for your situation.
What size inverter do you need to go from ac to dc for a Kenmore model 16562 chest freezer?
A: It not size but rather capacity. the capacity will be the ac power consumption AC volts X AC current that will get Watts. So the capacity of the inverter should be the same watts plus a safety and efficiency power if the watts is 100 watts i would buy a 125 watts minimum
You are 5foot 7inches What size cricket bat handle would you need Small medium or large?
It doesn't matter what size bat handle you have just get the right size bat then try the different handles and then pick the one that feels right.
What size amp do you need if your sub is 300 rms?
300 watts or less.
What size amp should you get if your getting a 12 alpine type-x?
well each type x subwoofer can handle 3000 watts max and 1000 rms (recomended) so about a 2000 watt amp should give u unbelievible bass, if u have 2 alpine type x 12's u need can handle 6000 watts and 2000 rms
What size of an inverter generator would you need to run a MacBook Pro?
Look on the AC power adapter and read its rating in watts. You will need an inverter with at least that output capacity.
What size capacitor you need for a 1000 watts amplifier?
It takes 1 farad for every 1000 watts so u need 2 farads.
What size winch do you need to pull a 97 Chevy 1500 4x4 extended cab if stuck in mud?
you would need a 6000 lb or more to handle it
If a speaker is rated at 200 watts RMS at 8 ohms what is a good wattage to run to it?
it would depend on what brand and what size sub it is i would recommend 250 watts
