Product Description said, "60 seconds of winding provides approximately 2 hours of power." Is it correct?

I can not say 2 hours but I would recommend them with out a doubt. Great product.

I can't say that it is true. However, I can say they work well, very bright, and the price is fantastic. Highly recommended.

Depending on what you are doing, the battery should last more than 2 hours of use.

It's definatly not the high capacity battery that comes with the leaf blowers it's best for small project with a drill. You will get 5 to 10 minutes in the blower but that's a guess

I have used it 30 mins. at a time without decrease of power. Have had no need to try usage longer than that.

It depends on how long you intend to run the appliance. Frig. 3-4amps @ 120V = 420 watts. Divide by 12 = 35amps per hour. Typical large battery has 150 amp hour capacity but not at that rate and not fully discharging. Regular batteries are cheaper and you will only discharge to about 11.5 volts. That is why most residential system use line inverters and sell back to the utility. My starting point would be 10 if I was seriously wanting to benefit from a generator / battery backup on these appliances.. A couple of batteries could take all the charge a 100 watt panel could produce for days. Store it, use it or lose it because you can't afford your design intentions here.

Yes. The manual also states that it should last 72 hours without being plugged in.

When battery is full it shows 2 hours 30 minutes. I don't think I get quite that much, but it's pretty close to that.

I'm not 100% sure I understand. It has a dedicated power cord. It will charge a battery in about two hours in my experience.

I never really timed it accurately. Maybe an hour on high speed. Its a nice portable work fan when working in tight places or setting on your bench. It won't replace a big workshop drum type fan. It comes with a/c adapter so you can use wall outlet to power it.

I don't have hard data as I usually recharge overnight (two batteries), but I have a sense that two hours gets you maybe 75%, 4 you are 100%. I have seen some remarks online with more precise data...

power draw is 4 amps @ 12 volts. So if you have an 80 amp-hr battery you'll get 20 hours.

I thought this had a 14 amp-hour battery and 200 CCA. But when I got it, the specifications for it actually said it had a 12 amp-hour battery and only 120 CCA.

I believe I read 12 to 15 min depending on how much amperage is being drawn, we have two power outages a week as we run on generators and need to change oil weekly. Sometimes down 5 min and have had no problems. Its really so you can shut down without any loss of work. Hope this helped you.

I am not sure, but I had it running for about 2.5 hours straight. Then, I did recharge it when I got home, but it did not take long to charge.

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

Just timed it so everyone would know for sure and it is definitely 2 minutes. Mine was running low on batteries last week and that would account for it shutting off at 45 seconds.
