Will this have enough juice to support my "Metro ED500 air blower"? My blower is 120V and 500watts. if so, how many hours/minutes of usage can I get from this power station? Thanks in advace.

It's only 17 amp hours so I'd say for 500 watts, about 10 minutes? Probably less? If you want more substantial running time, your best bet is probably to build your own kit with a solar charger battery, where you can usually find 125 amp hours or more, and then get an inverter and charger separately. It'll cost a lot more but 125 amp hours from a 12v battery should power 500 watts for over an hour.

That is a really good question and I'm not sure I can give you an answer for it. I have used my device strictly to jump start my car death battery so I don't really test it real well.Sorry that I can't be of real help, hopefully you'll find someone who can give you a real answer!!!

You did not mention the application, but more is better. There are many variables. Where you live, altitude, how discharged is the battery. A 15 watt panel puts out about 1 amp so you you need approximately 35 hours to deliver 35 amp hours of energy. If you have any two(volts, amps, watts) you can find the third. VxA=W or W/V=A or W/A=V It would be enough to run a couple LED lights, charge your phone, or run the computer for a few hours everyday.

Amp hours are a measure of power. Theoretically, the battery should provide 125 amps for one hour at the stated 12 volts. However, at this high a current, I wouldn't count on it. More realistically, the battery should provide 10 amps at 12 volts for 12.5 hours or 20 amps for 6.25 hours...and so on and so forth. My experience is limited because I use them (two of them) along with an inverter to run a refrigerator and a few other pieces of equipment in a back up mode. They have done great when I've needed them!

This device is 1250 watt/hours, meaning something that pulls 1200 watts (their limit) would last an hour. 504...nowhere near 10-12 hours.

This unit does not have a power supply, You have to provide a 12 Vdc power supply it calls for a 2 watt supply which is .166 amps @ 12 Vdc so a 1/2 amp or greater 12 Vdc supply would work. The next part of your question 12 volts is the pressure of the voltage and current is the flow of the voltage. The switching contact are rated at 5 amps @220 volts AC Which is a lot, I would stay with the low voltage 12 Vdc on these contacts and use a 12 Vdc external relay ( any auto supply store ) with a diode across the coil, for the higher switching voltage if used. It is cheaper to replace a relay than it is to buy a new unit, if you burn out these contacts.

The battery in this is a "22 amp/hour", so it should be able to give you 22 amps for 1 hour, 11 amps for 2 hours, etc. If a laptop needs 1 amp at 120V AC (which is the same energy as 10 amps at 12V), it should last 2 hours. You want to keep a battery like this charged 99% of the time (or it loses it's ability to hold a charge), so I hope you actually start with it charged, then recharge it ASAP after using your laptop or such. A solar panel can charge this, but I hope you realize how long it may take to fully charge it. If you have a "60 watt" solar panel set and connect this up, it will take at least 6 hours to charge it (which I get from saying 60 watts/15V charge power=4 amps charge supply and 22 amp battery/4 amps supplied=5.5 hours to fill it up). Other solar panels can be calculated how fast they'll charge in a similar manor to that by just trading out the solar panels watts rating, coming up with a different charge amp supplied, and dividing that into the 22 amp/hour rating. Some solar panels (like ones I got) don't even perform at 1/2 their labeled rating in what I'd call "ideal conditions" (not to mention cloudy conditions), so it may take a lot longer than what I said in reality.

Many CPAPs run on 12 volts dc. They will run from 12v battery through suitable connector.From my experience, a 35 amp-hour battery will serve for several days, not using a humidifier.Its doubtful this unit has enough storage, but you would need to know specifics on your CPAPpower consumption.

The only right answer to your question is, "it depends", because it depends on how much current you need to provide and for how long @ 120V AC.Since you are running a 12VDC input and a 120VAC ouput, you need about 10 times the current on the 12v side as you want out of the 120V side.Additionally, you need to have an understanding of Amp Hours capacity of the battery(s) used to provide the power to understand how long it(they) can provide the power needed.

yes, the unit will provide power to an average 18 refridge for approximately 5 hrs..... You would need a 120v source of electricity to charge this unit during a power outage...If no 120v source of electricity if available, such as a gas generator, capable of outputting 120vAC power, then the power unit will operate until battery capacity is available. The unit would then have to be recharged once grid power is restored...

Not too smart, but here goes. Minimal power is consumed during standby. The unit operates on 1 or 2 AA batteries. Can't remember which. The power consumption of 12 volts is determined by the load size. Small load minimal draw. Large load big draw down. I am using mine on 60 watt aerators. They run 5 hours during the day and 8 hours at night. They are powered by 2 100ah batteries on each unit. They charging is done with 150 watts of solar panels. Batteries stay charged and the aerators run when scheduled. Sorry for the long answer that really says nothing.

What are you attempting to do? Does your coal burning stove have a blower you want to power? If so, charge your battery to full charge; remove it; hook your converter up to the battery and plug in your stove to the converter. When the "juice" is gone, charge up your battery again and start the process over. You could alternate with a second battery if you have access to one. What I don't understand, is how you will be powering the battery charger if you don't have electricity to power your stove blower (If I understand you correctly). I assume from your post, that English is your second language. If so, you need to re ask your question, as it was difficult to understand. And, please, do not attempt to do what you were asking about. You could end up killing or seriously injuring yourself.

Bucky, I don't really know, but if you check the A/C unit to see how many watts it uses, you should have the answer. If it does power it, I'd bet there won't be much juice left for anything else.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

Hello Batsaikhan. According to Mackie's spec sheet it accepts 100-240 VAC, 50-60 Hz. So I guess that means it can take 220v. The actual unit runs on 12VDC drawing 4A, so it is the brick that comes with it that handles the power. I have only run mine on 110V. I hope this helps.

I have used my powerhouse for tailgating seven times. Each time has been five to six hours. It still runs like new. Ensure you follow the instructions on oil and gas.In regards to amp output, the simple math below shows a maximum of 16.6 amps on a 120 volt electrical system. I have used it to run a 40 inch tv, a portable stove with two burners, and two fans at the same time. Power (watts) = I (current) x E (voltage)If everything runs on 120 volt, then it becomesI (current) = Power (watts) /120 or 2000/120 or 16.6 ampsA normal household circuit is just 15 amps.Source: http://answers.yahoo.com/question/index?qid=20091030105019AA1Frbo I have used my powerhouse for tailgating seven times.

We use this for our marching band to power the base amp. To answer your question, the battery is rated at 396 watt hours. So a full charged battery should give you at least 300 watt hours from thru ac inverter (120V). Your CPAP machine as described would need 240 watts for the 8 hour duration.

What is the capacity in Amp Hours or mAh of your 5 volt battery? Potentially this device will step up your 5VDC to 12VDC but I would not expect your battery to power it for very long. Especially if your 12V device truly does consume .8A. To put this into perspective I think you would need 28 AA batteries to power a 12V .8A (9.6 watt) device for 1 hour.
