First I will say I am disappointed in myself for not doing the research I should have done, it was all right there in front of me but my hopes got the best of me for sure... My previous post above shows what times I had running a regular light. This time I ran the Dewalt hybrid fan from the power station with a 25 foit 12/3 cord to the fan. With (4) 9ah Flexvolt batteries installed. The hybrid fan, which in my opinion is the best tool Dewalt makes, has very good airflow even at low speeds, and pushing great air at high. This test was performed by setting the fan on Medium for all involved...(in 75 to 77 degree Ambient temp controlled environment) - powerstation w/4 9ah Flexvolts installed. = test #1 = 38 hours --- -test#2 = 36 hours - using the fan on one 9ah battery it ran for 31hours at same medium setting. - the power station stated warning beep at those hours above, all batteries indicated 1 bar, I assume that this is low end the power station starts to want to shut down.... * I then placed a used 9ah battery from the power station into the fan and it ran another 2 hours no problem.... So add 8 more hours of run Tim to the fan test = potential 46 hours. BUT - if I inserted a single 9ah battery four times after depletingI would get 124 hours of operation at that medium setting. Big difference in times! I understand it's made to run tools, not refrigerators or other home appliances etc... And it may work well Running tools, and I wouldn't be running a fan constantly like that as well, but the testing shows it is not an alternative to using a single battery and doing a swap out..31hours single battery install vs 38hours power station is not that great of a difference. I was fortunate to find one at goodwill for $100, and I will keep it as a charger, and have the ability if needed to use as a power source. I intend to build a pure sine wave self contained inverter apparatus for running everything else, using the power caps available on eBay. I have so many batteries from different platforms, so this may be the way to go for my needs. Now that Big Red has a inverter on the market, I am sure Dewalt will have their own here shortly if there is one thing I have learned, they do not sit around and let anyone pass them up. And yes it will be $$$$ , But when the need is there, it will be worth it. My next test will be running the Ryobi band saw, and the 7491 Dewalt table saw. And a shop vac (Ridgid) these are the only corded things I own.

Since I am new to the power station, I have some questions.. I would assume the 6ah 20/60 flexvolt batteries would run longer than the XR 6ah batteries? But Is this the case? With the 10 larger individual batteries of the XR equal to the 15 batteries in the 6ah FlexVolt wouldn't the run time be the same? The powerstation will not allow a 60v feed, it only allows a 20v feed so wouldn't they be equal and actually wouldn't the 6ah XR be more efficient since it is a bigger cell? I would think, and let me know if I am wrong there would NO reason to buy the 6ah Flexvolt at a higher cost than the 6ah XR batteries?? FYI - cells used in the batteries 6ah Flexvolt = (15) 2000mh 18650 = 30000mh 6ah XR = (10) 3000mh 21700 = 30000mh PS the 9ah Flexvolt uses the 21700 as well, which is good news

I got lucky a few days ago and picked one up at Goodwill for $100 Tested it last night, installed a 9ah flex volt, (2) 6ah and (1) 4 ah. Just ran a 60'watt lamp for 5 hours, the 4 ah was drained and it quit..... The other 3 batteries had plenty of bars left on them. For light loads, why the heck didn't they design this to keep working off of or down to one Battery? The 9ah battery should have been the last to go... Any answers to this? Bad design? Just seems odd
