How much wattage does it draw? Someone mentioned 120 W on an inverter but that seems high; looking to make this battery powered/solar.

At 12.0 volts (right off my power supply): High setting draws 3.5 amps, Low setting draws 2.7 amps. To test this I had to sit on it, as it has a presence switch. IE: 0 Amps, if your not sitting in it. My car Aux has 15 amp fuse, so plenty of headroom for two. Check your fuse to make sure. Good rule of thumb is to only use 75% of fuse rating.

Hi there. For camping. and sleeping on the back of my pickup truck. Im using a 100 watt solar pannel connected to a 125 mah battery with a 1000 watt power inverter. I also use a 200 watt heater( smallest I could find) so I wont drain the battery so quick. in other words this one can be use as well in a setu up like mine or if you want to use it in your car battery you would need to connect the 1000 watt amp DIRECTLY from the car battery. DONOT connect it of cigaret outlet. it will blow the fuse since those dont allow to go up to 1000 watts. any questions just ask :)

ihave no idea how many watts are required to run your machine, but here's the math so you can determine this. Multiply the battery's "Amp Hour" rating by it's voltage (12 volts let's say). This will give you the "Watt Hours" available to run the machine, presuming a fully charged battery. I presume also that the machine draws less than 500 watts....the rating of the inverter. Amazon sells a nice 12 volt 35 Amp Hour battery for about $65.00. SO: 35 AH X 12volts = 420 Watt Hours available (call it 200 watt hours because you never want to deplete the battery by more than 50%). As an example, let's say the machine draws 25 watts (check the labels or paperwork). So you have 200 watt hours available, divided by 25 watts = 8...the number of hours you should be able to run the machine with this inverter and that battery. Just find out the actual watt consumption of the machine and do the same math. By the way...for safety...I would leave the battery outsise the tent, with the inverter inside. I hope all of this was helpful.

The panel does not output 5W like the specs and other reviewers suggest. The integrated *battery pack* outputs 5W, but the panel itself seems to only output in the range of 1W to 1.5W. From the specs directly from the manufacturer, the battery is 2200mah, and it takes the panel 10 hours to charge it. If you work the math out, that means it charges 220mah per hour, which would be 220ma of current @ around 5V (maybe slightly higher?), 5v * .22a = 1.1W Just because the unit has the capability to output at 5W, doesn't mean it can collect power from the sun comparable to a 5W panel.

I had an old 1700 watt generator during sandy. It powered my fridge and a bunch of other small things. The 3000 watt inverter isn't overkill tho. It won't draw more power than it needs. Battery needs to be good and charged as much as needed. Car alternator at least. Cables need to be thick for 3000 watts.

This works as a battery maintainer, not a battery charger. If you want to charge a battery for a power inverter, you need a much larger solar panel. To put this in perspective, this provides around 2.5 watts maximum. The 12v power plug in most cars is capable of more than 100 watts.I have mine attached to a deep cycle RV battery and it will barely maintain the charge, even with the battery disconnected fro the trailer.

I believe it all depends on how much draw you are going to have. I connected two of these batteries to an old farmhouse's electric system via an invertor and basically ran lights (mostly LEDs) and charged my laptop, cell, ran a radio or two. My solar panels only produce 120 watts. I never had the batteries completely drained or even close to that and they worked fine. I would prefer to have more than two in the future so as to have more reserve when cloudy periods are extensive.Hope this helps!

It is not solar. Solar is the company name. You have to plug it in to 120V.

The Power Bright PW1100-12 1100 Watt Power Inverter can handle the 6.5 amp draw you provided when using with a proper sized battery which can handle the load.

1040 watts at an 80% efficiency factor or about 800 watts at 100% efficiency factor. 800 watts = about 40-45 amps at 12 volts which gives you a safety cushion of 15 amps with the unit. if you are going to run the unit at 24 volts, your inputs would be higher since as voltage rises with solar, your amps are usually cut by a factor of about 30-35% at each voltage increase(12/24/36/48 etc) without knowing what your panels are rated at, i cannot answer the number of panels question. just multiply your panel wattage by number of panels= total wattage. hope this info helps you. i can tell you this tho- i was pumping over 40 amps continuous into the unit when first hooked up and it wasn't even getting warm!. very well made unit/even better that its made in America and buying it supports other fellow Americans.

Voltage is not measured in Watts.....5 volts. It draws 0.4 amp or 400 mili Amp most likely. (it also makes sense). But why are you concern about power input??

It depends on how long you want to use the power inverter and how many watts per hour you are going to use and will you be charging the battery at the same time or just use a battery without charging .The formula is (amps x 120 v = watts X hour) amp draw should be listed on tag by the model number

as a previous owner of one of these i wouldnt recommend buying this inverter i had one and it didnt last but a few days on 2 100 watt panels wired paralell the most wattage i ever saw was 112 wats and 18.8 volts

Mine stays plugged in with no problems. I do not believe there is any significant power draw unless something is connected to it and is continuously drawing from the invertor. Then that depends on the rating of the vehicle battery rating or reserve capacity and the load drawn from the invertor, up to 120 watts.

this inverter must be connected to a 24 volt system or battery. if u connect batteries to it without something to charge the batteries they will drain very fast. you can get solar panels from amazon. the more watts the panels have, the more power it will make. look on youtube there are vids on solar they helped me alot.

Joe, It seems to be a little more than 40 watts. at 12v it draws 4 -5 amps - 48 to 60 watts. I use a 100 watt solar panel which will do 7+ amps, to charge the trailer batteries and run the frig freezer during the daylight hours. This arrangement has kept my ice cream frozen for four days in Death Valley (90-100) temps without starting the tow vehicle. .

Off grid 12v solar w/440ah reserve this unit would typically draw 5 amps when it cycles. DC power can be finicky, The better and shorter wiring or connection to your battery - battery bank, the better this unit will run. Try to use an independent or more direct source/circuit. Avoid plugging into a source already feeding other accessories. Also, make sure the vents are clear.Edit to add; 60-65 watts according to a dc amps to watts calc.
