On a full charge a 60W AC appliance runs for how many hours?

This has no AC inverter, but assuming you connect one up 60watts/12V=5amp draw on the battery which is rated 18 amp-hour, so 18AH/5A=3.6 hours.

Around 2 hours, the actual operation time will depend on how much electricity is required by the device and how you use it.

Well, my computer is using 300 watts right now and the UPS says it can run for 20 minutes on battery. If the conversion holds up, that'd be about 100 hours.

I concur w/abt 6 hours. My son runs this thing w/o charging for a few days @ a time.

No, it runs approximately 1 hour and a half. Then you have to plug it into power

I generally get around 4.5 hours. Most of the time I use the AC power. I use a hard drive not a solid state.

Full time. So don't expect it to run on a couple of small batteries. You'll need a small power supply.

Very late now. It can run anywhere between 1-3 hours depending on how much you watch. I have a portable backup battery that I use to run this little tv for hours. Recently, I bought a 25w solar panel to recharge the backup battery whenever the power go out.

Depends on the volume you want to achieve, and how long you plan to run it. I would say it would work fine for a couple hours at 70-80% power.

I powered these fans, a RaspberryPi, and a small wifi router (Wifi Pineapple) for over 6 hours with a 10,000mAh Anker power pack. If you're just powering these fans with a 20,000mAh battery, assuming they pull about 1A, then you're looking at 18-20 hours of runtime. That's just a guess though, as I don't have a 20,000mAh pack to test it with.

As with all d.c. appliances, just multiply the amps used by the hours. So if at the lowest settting (1.1 amps) for 8 hours it is 1.1 x 8 = 8.8 amp hours of power used. Look at your battery to see its capacity, for example 350 AH. Divide 350 by 8.8 = about 40, meaning it would take forty eight-hour periods without draining a battery before the battery needs to be re-charged. So you see it hardly makes a dent in the battery if used for a few consecutive 8-hour periods before recharging. It uses about the same as a single 13-watt compact fluorescent light bulb.

The short answer is "Yes". David Tullos says it will last 8 - 10 hours on full load (1500 watts) but I do not believe it will last any where near that long. The first link I have provided below computes the battery will last .66 hours at a continuous 1500 watt load and that makes sense to me. I have run a 2500 watt inverter on 1 of these 12 volt 100 amp hour batteries. The inverter must be a 12 volt inverter. The question is...how long will the battery last. That depends on the average (a refrigerator for example) or continuous wattage (maybe a 1500 watt heater running continuously) used by the electrical devices being powered. Of course the fridge doesn't run continuously so you have to take that into account. If you run a 1500 watt heater continuously off of this 100 amp hour battery you should be able to compute how long it will last. You also do not want to discharge the battery too much below 50%. There is a certain amount of research you need to do part of which involves using very thick gauge (probably at least 4 awg but maybe as large as 0 awg) cables from the inverter to the battery which your inverter documentation should tell you. The general rule of thumb for DC current is that for every 1 amp of AC current used by an appliance you will draw 10 amps of DC current from the battery. 10 amps of AC current will draw about 100 amps of DC current. Here are some links that might help. I do not know how reliable these are but they seem to be correct with my understanding of electricity and the research I've done. The first link seems to be the simplest to use by plugging in your own data. http://usasolarwind.com/Tools/BET.html http://powerstuff.co.za/battery-size-calculator/ http://www.bdbatteries.com/dcdcsolar.php I hope this helps.

I've run mine for over 2 hours but never until the battery ran out. I hope that helps.

CPAP units consume about 30-40 watts on average, so 7 hrs. operation would use about half the battery's charge. So, just big enough, if you recharge it during the day

Wh is watt hour. At home, if you consume 120V electricity at 8 amps load for one hour, that is equal to approximately 1000 watt hours, or 1kWH, which is same as 1 unit of power consumed.

It would run it for about 18 minutes if fully charged. The inverter has the power and if you have enough battery it will run fine.

I have found that a full charge will last for 1/2 to 3/4 of an hour if used constantly for the whole time. Also depends on how fast you run it.
