Good price for 2000Wh, but I can't this was ever $1500. Better name brands with similar specs are about $800, so decent deal.

I have this. Got it last winter to run my 3/4hp sump pump during outages and it works great for that. Seems to be of high quality and I've had no problems. I just wish it wasn't so heavy, but everything in this range is about the same weight.

How long could it run?

I didn't time it but it ran about 10 seconds every 2 or 3 minutes during a pretty heavy storm. In that time it handled the surge watts no problem. The display would dip to show a reduced time, but as soon as it was done pumping, it would go back to 100%, going down only slightly over true duration of the storm. The unit can also be plugged into wall power as a pass through, so it only uses the battery if there is an actual outage, charging otherwise.

I think if it was a full outage and the pump ran continuously, it may only last a couple hours. But usually the pump doesn't run continuously so I think I could get a lot longer running time from it. I may get a gas unit as a backup backup!

If you guy want a battery backup system for sump pump, you could buy SUMP PUMP INVERTER AND BATTERY 12V. Then connect them together with battery cables and tight down some bolts. It could SAVE 50%. Plus, it is easy to put in tight space. All-in-one unit like this one is BIG AND HEAVY.

Here is sump pump inverter and battery look like: https://ibb.co/MDRyGkJr

You could read and see many people reviews and pictures of their system on Amazon here:

Posted in another thread, but this is not a deal. A Pecron F3000LFP destroys this deal when it come the dollar per Kilowatt Hour capacity and a higher wattage output.

This is not a deal as the Mega 2 has been at $599 before but you're comparing something in a different category.
There's a reason why manufacturers make 2000w/1000wh 2000w/2000wh and 3000w/3000wh power stations.
Each fits a different need.
63lbs(Peron f3000) is a bit of a burden to carry around while 48lbs(Oupes Mega 2) is just at the limit of portability.
As someone who owns just about every power station categories, I find the 2000w/1000wh and 2000w/2000wh the best sweet spots.
I have a Pecron E1000, Dabbsson 2000l Dabbsson dbs3500 and Oupes G6000.
I tend to favor the Pecron E1000 and Dabbsson 2000l the most. Powerful enough to run just about everything and light enough to haul around. If I want the extra capacity for a long camping trip, etc., I just bring a regular lifepo4 battery with me.
But I do love the Pecron F3000. Best value power station around. It's just that that portable.
