SHNITPWR Universal AC to DC Adapter 3V ~ 24V 2A 48W Switching Power Supply

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!

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.

Recomendado

I bought this for prototyping small electronics and testing junk electronics. This product does what it says on the package, but the voltage readout is a touch inaccurate. Voltage will drop slightly when under load (which is expected and normal.) Always tie a voltmeter into your circuit and watch the output carefully. If you want something to power a specific device you use on a regular basis, get an adaptor with an adjustor that "locks" to a specific voltage. This dial can be accidentally bumped and the voltage set to a new level quite easily.

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

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

Great

Very easy to use and will power up almost any device with the great number of adapters offered.

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.

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.

boa qualidade, porém atendeu parcialmente minhas necessidades.

Fonctionne très bien

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