Trisonic TS-505B 1.5 to 12 V 500MA AC/DC Adapter

This thing is huge. Easily takes up the good majority of your power outlet. Fortunately this thing makes no noise, stays cool (even after 24 hours of continuous use), and all the voltage settings are true. I bought it for the Led light on my fishtank after going through an unreasonable amount of AAA's.

Voltages are horribly inaccurate. I hooked this up to one of my baby's vibrating bouncy chairs, and noticed it was vibrating much too fast. I pulled out my Fluke multimeter and checked the voltages at all settings. Here is a chart of what voltage the adapter says it outputs, versus what it really outputs.Adapter Actual1.5v 4.38v3v 6.87v4.5v 8.91v6v 10.95v7.5v 13.01v9v 15.58v12v 20.76vThis thing will fry your electronics, if used for anything more complicated than driving a simple motor.The only positive things I can say about this adapter, is that the polarity switch does indeed work.

This product initially worked alright but it just shorted and melted all the internal components, warping the outside housing. We were lucky our house did not catch fire. Had the adapter plugged into a keyboard when the keyboard all of sudden turned off and then I could smell an acrid odor.

A perfect product. You basically have a diverse electrical adapter that gives you the simple adjustment in amperage, polarity, and DC voltage. That means that for a few bucks, you can replace any charger/adapter you have!

I needed a 1.5 v adapter for my myzone tv headphones, One review said same thing but said he used 4v setting, I tried 1.5 v first and it works fine. Will save a lot of money instead of buying batteries.

Works well. I don't know why "SONY" is in the title, it's not s SONY product. -1 star, as it doesn't have a 9v adapter, and only 500mA output. Otherwise works perfectly for many small devices.

Item arrived on time. Item worked with two of our decorations but not with a third item. Am not sure why? I am happy that two decorations now do not require batteries.

Must buy Universal
