1) The 5.5 x 2.5 mm connector tip is not included. Considering that it’s one of the most commonly used connector sizes on the market, the choice to omit it is baffling.
2) The supplied cord is too short at only 5 ft. It’s woefully inadequate if you plan to use this adapter with a keyboard, or any other electronic device that’s positioned beyond 5 ft from an electrical outlet.
3) Voltage is limited to 12V. Many other adapters offered on Amazon go to 15V.
Verdict: if Hosa addressed the above flaws, this could be one of the best adapters on the market. As it is, there are better choices out there.
The supply is rated for 1200mA and can run on AC at 100 to 240 volts. Under a 580mA load on the 12v setting the voltage fell from 12.06v to 11.82v. On the 6v setting it fell from 5.68v to 5.48v. This is pretty good. With the regulation, there's no risk of damaging the device being powered, as long as you set the voltage and plug polarity properly.
Compared to another of my universal supplies, this one causes a bit less buzz when powering a little self-amplified speaker. I had to hold the speaker right up to my ear to hear the noise.
Since it's a switching power supply rather than a transformer, it's small and light compared to other universal supplies I've seen. When left plugged in with no load, it doesn't get warm at all.
The AC plug prongs fold down for easier storage.
The only criticism I'd offer is that the selection of plug tips could be better. I'd like to see a couple of the headphone-like plugs, and a 9-volt battery connector. If it had 12 plug tips like some other supplies, it'd be a perfect product. But I think you can buy other tips of this type; it seems to be a standard.
I may buy a couple more of these.
This adapter works fine. I used a meter to confirm the switch regulates as advertised. One thing to be aware of is you can attach the right-angle tips in positive or negative polarity by aligning the 'TIP' marking on the cable socket with the '+' or '-' sign on the tip. This is mentioned in the instructions (but when's the last time you bothered to read them for such a device?).
It's a very similar design to the Insignia brand universal adapter sold at Best Buy that has straight-length tips rather than right-angled but doesn't allow you to flip polarity - and costs about $7-8 dollars more than the Hosa.
The tips themselves fit fine: effects pedals, keyboards, portable CD player -everything I've tried has a matching tip that gives a snug fit. Perhaps there are some oddball devices out there with proprietary plugs or certain outlets where the right-angled tip can't get in deep enough, but that's going to be the exception by far.
If you're looking for something to use unattended, I agree and would spend more for something rated. But if you're strictly set up/tear down this power supply is cheap and versatile.
The voltage isn't perfect, I was getting around 7.6 with my multimeter. If you're looking for a power supply that is more exact you'll spend more money.

I do have uses for it and it is handy to have around, but... I'm not using it right now. Still, good to know I have it.
My factory adapter with same config was working fine.
