I have several Finersi devices. This one is terrible. Banana connectors don't fit the front panel jacks. I did not power anything because of that. Menu keeps switching back to Chinese. Found out after received that no power supply is included. For added apprx $30 could get a power supply to make it complete. There are lots of power supplies available for what this would cost if it was complete.I will return this. Bad idea.

I wanted a portable power supply that could output 24v reliably. The pictures make it look like it comes with a small wall adapter for DC input to connect to the DC input jack. I saw the title show "No Adapter" but when compared to the more expensive option from the same company, the only shown difference is a PD wall adapter. I want the DC power supply shown in the 3rd picture. I am very disappointed that it did not come with the wall adapter to use with the DC input port to allow for 30v to get 150 watts.I then thought that PD input made up for this issue to get me to 24v but looking at my Anker GaN 120 W wall adapter, it is only capable of 20 volts. That's what I see when I plug it in, 20v. I tried a large Anker power bank with PD and it is only capable of 20 volts. I am not sure if the PD standard allows for 30v or is at least not commonly available based on some quick searches.I cannot find the wall DC adapter listed anywhere from this company and the closest thing I can find on Amazon looks like a large laptop power supply. That defeats the purpose of the portability this device is supposed to offer.This will not fulfill the need that I wanted. I do not recommend others purchase it based on these shortcomings unless 20v or less will suffice.

It's a nice product, but it does not come with a power source! This makes it pretty much useless initially. You have to purchase your own power source. The ad on Amazon said nothing in regards to this.So if you purchase it, know that you're going to have to Fork out more money to purchase a power source.Won't be buying a second one...

I learned about this product from another reviewer and decided to give it a try. So far it has worked great. In addition to supplying a stable voltage, the device provides a good bit of useful information, particularly for those who like to play with electronics. It's definitely a good device to have in your toolbox.

The display is awesome, and the form factor compared to bench supplies is amazingly compact. The value is pretty good considering these advantages. The only thing I don't like - since it can't boost voltage - it needs 1.5 volts + desired voltage as input to output desired voltage. This means that for devices I run requiring 24 volts, I need to find a supply 26.5 volts+ with a barrel connector. Note that most USB type c adapters for laptops are 20VDC - so unless you require less than 20volts you'll need to do what I did. I was able to find a starlink 30VDC adapter, and modify the barrel connector to fit this - but it required soldering and was a pain. Now I can output 24VDC.

Very good looking power supply. Not as convenient as a real bench power supply but great for remote troubleshooting

With PD or 13v input it would only put out what the source was. Assumedly it doesn't have a buck or voltage increase circuit.That said still 5 star usefulness. I don't need beyond 14v typing. Very accurate with no load. .5 amp load, it may have dropped but also have been my load was RF based.It's literally the size of 2 cell phones on top of each other. Very usefull and portable kit

Very nice little PSU. Until you have one and try it out you won't realise how useful it is. Very accurate readouts. If you ever lose a USB charger or indeed any charger up to 30V DC/5A this is a great emergency replacement.......if you have it! I power it from an old 19v laptop PSU (5.5mm/2.5 barrel plug required) and also if I need to, a PD-type fast charger PSU via USB C

This little DC power supply is awesome to use with your PC. I can use a USB-C 20 V 6.5 amp laptop charger to power it and it is great for fault. Finding on laptop motherboards. I use it for my YouTube videos. That way I can display everything on my screen. Definitely worth it. You can even use an additional DC power supply to power it over 20 V if needed. If you have a DC power supply already and want to be able to have that data on your PC for recording. This is also a great little additional tool.

I was looking for an ultra small, usable power supply for my field work and found this. It really does help gat it claims, and pumped 4A at 19V with ease. For an hour. I was waiting for something to get hot or fry, but it didn’t. Nice accurate controls and many configurable options. One thing to know is that you do need the optional wall plug to get the higher voltages. I didn’t understand that at first. Otherwise, it will reference the highest voltage you supply it and will reduce from there. It’s really small and well made. I own many of their products and this did not disappoint. The DPOX180H is so good, I bought too!
