Package included
1x 72W Universal Power Supply Adapter; 14x DC Tips; 1x Reverse Polarity Converter Cable

Attention:
The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~24.5V. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply's voltage range is 3V~24V, not 3.5V~24.5V.

Caution:
The 17.cm short black power cord is a reverse polarity converter, not extension wire. It is used to reverse the original polarity of the power supply output port ( reverse the internal positive pole to negative , and the external negative pole to positive). Please confirm the polarity of your devices’ power port before use. If the positive and negative poles are reversed, it will cause short circuit and damage your device.

Customers are dissatisfied with the voltage of the adapter. They mention that the dial for the variable voltage is not great, the voltage isn't constant, and setting the proper voltage is somewhat difficult. They also say that the voltage would fluctuate slightly and that the knob stops adjusting after the tick mark is only 2/3 of the way. Customers also mention that it's easy to bump it and have the voltage rapidly change in whatever direction it is bumped. They say the adaptor is slow and hard to get the desired voltage.

I used this to replace a rare power supply for a Google Home Nest Pro router. It works well! I occasionally have to readjust the voltage as it drifts by a small margin every now and then, but I've had no problems with any of the electronics I've used with it.

The attachments included are very helpful, and have helped me with any small hobby projects I've worked on. It is a great and cheap alternative to a bench power supply.

Reviewed in the United States on December 23, 2023

Style: 3~24V3A72WVerified Purchase

Thought power converter for a Christmas decoration had quit working, so ordered this one. Very hard to adjust power output, got it close. Apparently decoration has died as it still won't work. About done with you people. Out of the last 6 orders only 1 was as expected, the others were the wrong size, defective, or had no instructions included. The only thing that has worked as expected was the JVC vcr remote control. At least the basic functions work on this, which is better than not at all, which at least makes it useable. I have only ordered from you the last few orders due to where I live, in the middle of nowhere. Used to be convenient, no longer now when the received items are useless. This seems pointless to continue as this is not even close to convenient, and the items were relatively inexpensive making returning them not really worthwhile. The so called fitted spark plug wires I ordered for my 350 Chevrolet engine work as far as making the vehicle run, but now there are spark plug wires strung all over the engine compartment as most of them were way too long. Way too much not as described or no instructions. If you notice future orders are much fewer of not any at least you know why.

Works as advertised, very sensitive adjustment

Reviewed in the United States on November 27, 2023

Style: 3~24V3A72WVerified Purchase

This thing should be in very household. If you have many electronic devices like I do, occasionally one stops working or charging. Having a versatile and adjustable power supply is a must for troubleshooting and getting a device going while you order a replacement power supply. It has many connects sizes that should fit almost every need.

I will give you one WARNING. The device comes with a six-inch extension output cord that seems to have no use and does not state what it is for. Well, what it does is reverses polarity, so you should never use this unless you are sure your device has the positive power on the outside of the connector, which is very rare. Reversing polarity may fry your device! It's nice they included it, but there should be a big red label affixed to it that states what it does.

I dinged it a star because the voltage potentiometer (adjustment knob), is way to sensitive and its hard to set the voltage exactly, There are no detents or click in spots for the voltages so you have to fiddle with it and hope the knob doesn't get bumped to a different voltage during regular use.

Other than that, it's a keeper.
