Customer Reviews

Bought this recently from Amazon for $180.00 I will say its worth about that. I tried a few high wattage things in it like a hair dryer, Iron, coffee maker, just to see how long I could use it. These are things I could never think of using in a standard 1500VA UPS, (Which I have for comp and such) All of the devices ran well, the hair dryer probably sucked it down the fastest, (Set high 1500watts), lasted aout 7 minutes before the warning started going off. The unit ran about 5 more minutes on medium setting before the battery dropped to 20 percent. The battery did recover to 50% after turning off dryer, so high wattage appliances I think are a bit much for the batteries to output continuously.
The unit is heavy, about 60 pounds. For the money, I would buy again. I figure I should get about 6 hours on a computer with a flat panel attached. For most short power outages, this will get you by for a few necessities. Anything longer you will have to go generator.
The description reads as though you can use it for a fridge and other high wattage appliances, which I guess is true, but misleading as I would imagine a fridge would kill it in about 10 minutes or less.
All in all glad, I was able to purchase for the $180.00. If nothing else you can dry your hair when the power is out, and make coffee, without having to hook up the generator.
UPDATE:
So I wanted to update this review. The unit gave out after about 18-24 months. Cant tell exactly when it lost its capacity but it would last maybe 5 minutes on light load. I took the time to tear it apart and found three 12 volt 17ah SLA batteries wired in parallel. They were pretty much useless. Tried to bring them back but as most here know once an SLA battery gets near end of life it is almost impossible to get them back from the dead even with a good quality desulfator. I got lucky and found 3 new Panasonic replacements for $25ea on EBAY and installed those. (A good quality SLA battery in this range is usually about $70 bucks each). Unit is back up and running like new. I would assume most people would not attempt this nor probably should they. High risk of shock even with the unit unplugged. And many parts to disassemble/reassemble. If you do attempt, take lots of pictures as you break down and be carefull of wires. Doesnt matter how long or how many times you have handled electricity, only takes once.

UPDATE: After a few months sitting in the corner being charged, I tried it out today. Apparently there's at least one bad cell; a 600w load exhausts the batteries in about 45 seconds. So I revise my rating to ``piece of junk,'' niche or no niche. It needs a much better quality control on the batteries.
ORIGINAL Post:
Pros : about three times the run times of a comparable capacity UPS, based on battery capacity (3 x 17AH, vs typical 2 x 9AH in a 1500VA UPS). Maybe nice to have around to switch to when a regular UPS runs down in a long power outage. I got mine for $180, which would be a good deal in the UPS market. The current $380 would be too high for me.
Cons : a lot of cons. It's hyped as if it's going to help out in the gas generator alternative market, but has nowhere near the capacity you'd need in terms or runtimes. It could run a sump pump for an hour maybe (one cycle of my 1/2hp sump pump runs it down to 80% of charge, so 5 cycles would run it out completely), which isn't going to help much. For all this stuff, like refrigerator and so forth, you just need a gas generator.
The transfer time (80ms) is too slow for a computer when the power goes out. A UPS is ten times faster. No power conditioning.
Really heavy. A woman is not going to like dealing with it. Handles are convenient for the weight though. A Honda EU2000i 2000w gas generator weighs the same.
There's no powered-off charge-the-battery-anyway mode, and it consumes 10w when plugged in. Can only be powered off when not plugged in, so you'd have to establish a routine to keep the battery charged if it's not in regular use.
So perhaps its niche is as a backup UPS when the power has been off too long for the regular UPS. Plug the computer into this, then. When the power comes back, charge it back up and put it back in the closet.
It's a nice product, just one with no obvious use.
Get a gas generator for the sump pump and the refrigerator.
