How big of a generator would I need to power this charger?

It has. 10 amp output & will recharge in 10-12 hours so even a small generator will have 10 amps of output but the amount of fuel it holds is key. Will it run up to 12 hours without running out? Or you'll have to refill it.

Depending on what else u run with generator , it does not require many amps when running . A 3kw will be fine Maybe a lil surge when u first plug it in

I'm not an expert but I don't think this thing draws hardly any watts or amps etc. I lost my instruction booklet because half of the unit stopped working and MinnKota said it can't be fixed. I kept it to use as a trickle charger for cars, boats etc. I would think almost any generator would make this charger work. It' basically a trickle charger so it's gonna run your generator a long time to charge a battery a battery. You might want a more powerful charger depending on your use to shorten the generator run time..

I'm not entirely sure, but the total charging output for two batteries is 10 amps. I would say a generator output of 1150 watts (amps times voltage = watts) would be needed. The on-line manual may show a more specific information. I don't have easy access to my manual right now since it's with my boat which is in storage right now. I will say that at full charge to both batteries, the unit does get very warm, thus the large heat sink fins built into the case. This is a well built, solid unit. I have had no problems with it. I hope this helps.

On my generator, there is a plug on the panel to plug the charger into. I found this did not work very well. I purchased a tender/charger like this one: Deltran Battery Tender (021-0128) 1.25 Amp Battery Charger and attached it to the generator's battery. This type of charger allows you to leave the charger attached so the battery is always ready to go. Ellis

You might want to consult an electrician on that question. We only use the generator to charge the battery on our rv.

Yes, but beware, you probably want to charge more than just 1 battery, more like a small bank of batteries. For example, I have mine hooked up to a small bank of 8 SLA 12V batteries giving me about 1500 watts stored to power a 1200 W Inverter for appliances. It's like a solar powered battery pack so that I can work and have phone conversations in the most odd places (no generator noise in the background, just pure silence or nature noises, it's awesome). You'll want a decent charge controller (I bought a 10 Amp controller, which is overkill, but has the better charge-methods and pattern that I wanted). Good Luck!

You will need to make an adaptor. Buy the plug and socket and a small piece of wire. Your generator will need to be around 8000-9000 watts. A motor home store might have an adaptor plug to fit your generator and welder.

It should have no problem if it draws less than 20 amps. I use my generator at times to run a similar unit and have power to spare on my camper. I think mine has a start up of 14 amps and settles in around 12 amps.

That depends on what you are going to do with it. Are you going to build a 'solar generator' on a cart, put them on a pole, a house, or an RV? In some cases you will need mounting brackets. In some, you will need longer cables. You might also want a better charge controller, though it isn't required. If you want to run a 120v ac load, you will need an inverter with a high enough wattage to run your load. Bear in mind that extra current is required when starting a motor, like a pump or refrigerator. In all cases, you will need batteries. Google is your friend.

There is a 30 amp outlet on the generator, and with this adapter, you can use 3 regular 110 outlet extension cords with it, by plugging it in.

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.

If all you need is a cord, you can buy the plug and wire at Radio Shack. Look at the charger rating for your unit if you need the wall transformer too. This puts out 12 volts at 3 amps or 36 watts. Don't try to use it on a piece of equipment that requires more amps!

Yes as long as the generator has the 30amp outlet. If the generator doesn't have the 30amp outlet you can use an adapter or just use a good 10 or 12 gage cord.

I think it's 3 to 4 pounds....remember it is not just a generator if you hook up a battery to it it'll run as a motor..so that means you cannot charge battery with it without a (diode to stop electricity going in to the motor from the battery)

The generator dimensions are 15inches tall, 16 inches wide and 11 inches deep. The attached handle will stick up about 4 feet but it can be removed. I am not sure about the charging outside. I am in an apartment building on the 11th floor but do keep mine out on the patio on trickle charge. It sits in a well protected corner of the patio. It is quite heavy, so you have to be in shape to pick it up and carry it. The attached handle and wheels do make it much easer to move around like a heavy item on a hand truck.

Yes it worked. Ensure you keep AC charger plugged into generator while not in use or battery will likely go dead.

just look at the rating on the box. I'm using a smaller generator, and it works fine. BTW, there is a similar unit from the same company rated for 7000 watts (7kw), if you need to go larger. The box is the same size I think, but the connector arrangement is probably different, to handle more amperage. Good luck!

Actually the charger is rated 15 amps at 120 volts ac input. This is the load that the generator sees, not the 48 volts at 25 amps ouput. Using the formula P=I times E we see 120 volts times 15 amps gives us a draw of 1800 watts. Much more than your generator is able to provide.

I haven't made time to try the new charger - I have a 2000 watt Yamaha generator I wasHoping to use - the charger uses up to 1800 watts - my generator is rated at 1650 continuousI wouldn't even consider a 1000 watt generator!Bottom line is charger will use the mostEnergy on a fully discharged battery set. If you are just topping of batteries it will use less. 1 kw generator - I wouldn't do it!
