Variable Transformer 10 Amp (1000 Watts); 0~130VAC Output ISOLATION & LCD Volt Meter
Seems to be a quality unit

The device appears to be solid and well built. It's the only unit I've found that has both a Variac AND an Isolation transformer in one unit. It's roughly half the price of buying both units separately (not to mention the reclaimed workspace). As near as I can tell, the output is indeed isolated from the input, as claimed, including the ground. I'm just a hobbyist, not an electrical engineer, so please accept my opinion in that that context.

DC Barrel Plug Adapter to 3.3mm x 5.5mm with center pin (1.0mm) plug from 2.1 x 5.5mm
Hard to find adapter did the job!

I had to get Chat GPT involved before I found this adapter, and it worked. I'm happy :-).

Custom length power shade charging cables were made properly, worked properly, were delivered quickly, and reasonably priced. Hans was great to work with

Hallmark ornaments

We have some older hallmark ornaments that were designed to plug into the string of tree lights. But the lights changed and the ornaments would no longer work. This power supply works as a perfect substitute.

Perfect for guitar pedals

This works perfectly on my effects pedals that optionally take 12v for more sonic headroom (or similar).

I just ordered more.

1000VA Isolation Transformer, 117VAC to 117VAC
Superlative

I ordered a 20 some pound transformer and was thinking I would be lucky if it arrived unscathed. It was in perfect condition mainly due to the outstanding way it was packed. Triple boxed with foam between each layer. It was truly gorilla proof. And the product inside is well made and reasonable price. What a contrast to the business as usual companies that I normally deal with. Thank you.
