What should other buyers know?That's the review question. IT WORKS. About covers it.

A very useful universal charger

Purchased to power a portable Shortwave Radio. This power supply is a switching power supply and produced broadband noise that Desensed the received signal across all bands. Radio came alive when power on batteries. Found an old linear wall wart power supply and now use that for the radio without any problem. Bottom line: This supply is good for an application for any application not involving a radio.

Works perfectly.

Amazing

I've only used this as a 12v adapter and haven't found a need for anything lower, but appreciate the flexibility.The Belker adapter is a little expensive compared to other 12v adapters, but it's rated up to 3A, which is not as common (I've accumulated a lot of 1.0/1.5/2.0A 2.1/2.5/5.5mm adapters over the years), and gave me more headroom for the power draw of my intel nuc.Now 4 years later, I needed a 1.7/4.0mm 12v barrel adapter for an aruba instant access point, and this came right in handy-- just change the tip.

I was looking for a charger for something and I have bought a few and none of them have worked but this one.It takes a little bit to figure out what plug and voltage you need but affter that smooth sailing.

I bought this exact same converter a few months ago. It was able to handle a wide range of voltages and plug types and importantly it was able to handle either positive center or negative center by simply switching the way that the tip plugged into the adapter cable. This is what I expected when I purchased the same item again.Now when the new one arrived I found that it will only handle positive center without purchasing an additional convertor from their store. This is completely unacceptable for a product that claims to be a "Universal" adapter. I will not purchase this particular power adapter again since there are a wide range of this type of product available that do not suffer from this obvious deficiency.
