SHNITPWR Universal AC to DC Adapter 3V ~ 24V 2A 48W Switching Power Supply 3V 5V 6V 9V 12V 15V 18V 19V 20V 24V 1A 1.5A 2 Amps Adjustable AC/DC Converter Transformer with 14 Tips & Polarity Converter

Voltage adjustment was the exact thing needed to replace the power supply for a 19.5v POE switch for my cameras. It was much cheaper and easier than getting a new POE switch as they are not being made anymore by the manufacturer. Just be mindful for you applications the polarity of the tip!

Ease of use and compatibility is good. Quality product. Nice adjustment of voltage.

The product is very useful and handy the only thing wrong with it is that if you accidentally set the voltage to high the item you are charging or using will not work anymore

Great

This product is just as described. The input plug is a North American two-prong plug, and the output plug is a standard 5.5mm×2.1mm barrel connector. (Despite the plug, the product works on any mains/wall power anywhere in the world,100~250 V & 50 or 60 Hz, and all that is needed is a physical plug adapter.) The various output plugs that slip onto the standard barrel connector include a connector for bare wires, a USB Micro-B plug, a USB C plug, and a range of barrel connectors. The variable voltage control includes an On/Off switch. The version I received included plastic flanges with three screw holes for mounting the power supply body on a wall or shelf. I did put a 12V 3.4A load on the power supply, and the voltage set to 12V did then drop to 6.5V, but since the power supply is only rated to 2A, this was no surprise and does not say anything negative about the product. It recovered nicely and resumed operating normally.

Attachments simply do not work. Tested connections with an OEM power adapter, works fine. Then plugged in this one with the same rating: ZERO response. Tried several devices, NOTHING works with this power adapter. I have two of them, BOTH don’t work

Best $25 I ever spent I use it to charge things up to find out if batteries are chargeable this thing is amazing got to have it can't live without it

Concuerda con la descripción.

1- Arrived on time 2- Comes with many different tips to fit many devices 3- Provide Min 3.5 V up to 24.5 V. 4- It gives + voltage rating by 0.5 V than what is on Voltameter and this is common with all other adaptors that I had. 5- Comes with reverse polarity cable.

boa qualidade, porém atendeu parcialmente minhas necessidades.

Fonctionne très bien

Excellent product especially for model lighting projects which require low voltage levels.

An AU socket not provided despite this being sold on Amazon AU. But this does support 240V AC input so it isn't anything that isn't fixable by using a converter or possibly bending the poles... which I don't advise. I have also noticed that the voltage counter is a little weird around <5V but that might be an issue with it not being able to get rid of the power properly. Otherwise this product works well and as advertised.
