Variable Transformer 10 Amp (1000 Watts); 0~130VAC Output ISOLATION & LCD Volt Meter
Power Shack Isolation Variable Transformer

Could not be more pleased with the product and service provided. Took a while to find a product that combined a variable transformer with a true MAINS, ground isolation. Unlike most cheaper competitors offerings, the digital readout and dial for this transformer is fairly accurate when checked with a DMM. Great product for a hobbyist tech.

As expected

I can’t imagine somebody could mess up a power adapter and in this case, they came through as expected. They worked perfectly and it seems durable.

A Great Variac At A Great Price!

I've been considering getting a variable output isolation transformer for quite a few years, but I always assumed that they were expensive. When I purchased a Japanese market synthesizer (100 volts AC power requirements), I needed a step-down transformer. During my search, I came across this little gem at a very surprisingly reasonable price. The reviews were good, so I bought it.

It was shipped right away, and arrived within 2 days. It's a wonderful unit, and it works perfectly!

I would highly recommend that AC-DC PowerShack be checked out if you're looking for this or any other product they carry. You won't be disappointed!

DC Barrel Plug Adapter to 5 x 3.4mm with center pin @ 1mm plug from 2.1 x 5.5mm
Great adapter!

I used this adapter in combination with a USB C to 2.1mm x 5.5mm to create a USB C 12v adapter for my equipment. Works great! Now I don't have to be tethered to an extension cord while I work.

Fit is perfect, quality is decent. Couldn't ask for more.
