SHNITPWR 30W Universal AC to DC Power Adapter 3V to 12V 2.5A Power Supply 100~240V AC to DC 3V 4.5V 5V 6V 7.5V 9V 12V Adjustable Variable Converter Transformer with 5V USB 14 Tips Polarity Converter

It worked for me but the wire quality was on the poor side

I used this to provide external power to an old radio. Voltage selection and selection of the appropriate connector was easy. Lots of connectors to choose from, unit runs nice and cool. Ig has a powerful blue LED that may be distracting for some but I’m impressed with my purchase.

My Fire TV box suddenly stopped working. I determined that it was the power supply rather than the box which had given up the ghost. I settled on this as a replacement as it delivers a similar output current and can be set to a similar voltage as the now defunct power supply (5.95V 2.5A) and can also be used for other devices if necessary. My Fire TV box is now working again without any problems.It comes with an impressive array of connectors which should mean it fits most devices, however for the specific purpose I bought it for no additional connector was required as the built in one was the right size for the Fire TV box. The others will be handy if necessary, though. It also comes with a reversal lead should it ever need to be connected to a device which requires a negative tip.I like that the voltage selector is on the back of the device where it can't be easily knocked to the wrong voltage.It tells you that you shouldn't run it above 80% capacity or it will get too hot so I've put my hand on it after several hours of use with the Fire TV box and it is barely warm.The only downside is that is worryingly light which makes me wonder how robust it will be.

Does what it says. Versatile and it is used for other appliances when power packs fail to function. Cheap & quick delivery.

Bought for an zoom guitar effects pedel. Works well and comes with excellent choice in couplings. However wires are light weight, would not take much abuse. Noted also the polarity changer has a poor grip on the output plug.

The number of tips, combined with choice of voltages/polarity make it an ideal replacement for lost/broken adaptors

Worked intermittently. Opened it up prior to throwing away and founded unsoldered wiring soldered it and now able too use it perfectly . But shouldn't have to open the electrical item to check safety

I needed a power adapter that could reverse the polarity of the output, this worked perfect.
