Seven Star SS801 Universal Ni-Cd & Ni-MH Battery Charger

We bought this to be able to use a tea maker we had bought oversees. The 3ooo W unit did not last for than a couple of months and we had no success with the manufacturer or Amazon to get another unit or refund.

Unhappy customer.

Like another reviewer, I too thought this may only be a stabilizer when I opened the package. (I bought the similar but lower-rated Simran AR-350.) The package only refers to the stabilizing functions, saying something like "converts 75-140 V to 110 or 175-250 V to 220". However, my voltmeter shows that it does, indeed step-up 110 to 220 and I'm happily using mine on 110 V to power a 220V device.

I purchased the converter stabilizer to step a 220 line down to 110. I have a long run of Romex from my barn to a shed. I needed more power at the shed and by putting 220V on the line and then converting it back down I can cut my voltage loss by half. I was a bit worried since one review said that it did not convert but only stabilized while others said it converts 110V to 220V and 220V to 110V. It does the conversion just fine. A voltage check shows it to be spot on. The 110V outlets stay at 110V as the load changes so the stabilizer is working great also. This is while the input line drops from 220V to 205V. Great product!!

This is a little behomoth of tried and true technology. I expect to have it for decades to come. Truely it is Heavy Duty as it weight a ton, but is does the job it is meant to without issue. I use it at least a couple time a week for hours at a time, I use it with my 230v Vorwerk Bimby which also cooks at 100 degrees c, so I can definitely tell you this little transformer can handle the load. I do wish that it were a little more compact and lighter but other than that it is a jewel.

I am really pleased with this product. I do overseas dental mission work, and I have tried to get something to convert the power so that it runs my mobile equipment and charges batteries, runs hairdryers, etc. I talked to electrians here in the US. No one could give me the right solution. This is it!
