Review: Good for adjusting power to an electric motor. - I have an ultrasonic cleaner for cleaning vinyl records. It includes a little motor for spinning the records through the ultrasonic bath, but as designed, it's a bit fast. I used this to attenuate the amount of power it received so the motor would rotate more slowly. It worked perfectly.
Review: You Need(ed) or Will this Power Supply - Solid and accurate. I have this semi-perm bundled with a similar sized volt-ammeter to test LV LED (pkg to 5 or 12V), charging packaged "lost brick" items temporarily and other short-term supervised uses. Excellent value and much smaller and useful than a large ultra-regulated knob & button covered box that click-clacks & flashes. Wall (120V) cord a bit short & knob covers wide range so touchy, but not loose and amazingly unvariable voltage (based on external meter) Amps output dependant on draw from whatever it's connected to. Similar products offer less range and price equal or exceeding this AlloverPower unit, longevity unknown but has handled brief shorts and remote interrupt (OV shutoff) well. Plugs are good quality and very helpful. One of honest: Buy this now you need or will soon need project, handiman, hobby or 'where's that pwr brick' (wired to + center) must haves.

## Questions & Answers

**Q: Is it truly variable or is it tapped at specific voltages?**
A: Variable in 100 mV increments

**Q: Is this normal polarity? (+ sleave - center)**
A: "Normal" polarity is INSIDE POSITIVE so the unit cannot short out to a conductor and cause a fire or power something it shouldn't.  Any plug that has positive electricity on the outside is inherently dangerous.

**Q: How many watts?**
A: Up to 36. (Watts=amerpage*voltage)

**Q: Polarity reversible?**
A: There is a another listing of this same device on Amazon for $1 more (as of now anyway) that lists this same thing with a "polarity reverse cable".
