Is there a voltage switch? Am i supposed to assume this is not going to overvolt and destroy my equipment?

I used this for my Lenovo Y700 and it severely UNDER powered my laptop that it was actually draining the battery even with it in, not worth the cheap money it cost in my opinion..

how does the tip control the amps?

The amps are controlled by the charger, the tips are just there to feed the exact same amps to various devices which have different end pin connector types. Very handy as you can us the same charger for a whole lot of different devices. But the issue is this charger does not do what the seller suggests or mentions in the description of this item

Will this work for the hp monitor that is model hp 27vx?

Yes, The Gonine 90w universl dc power supply fit for hp monitor model 27vx.

Lots of barrel adapters that fits a lot of things

Worked on my Older dell even though the plugs looked different at first but then I tried it and I had power just what I needed

Worked great!

I couldn't find my cord anywhere and my laptop is only 2 years old. I found one on eBay and they sent me a different model than advertised so I had to return it. Then I found these and with so much to choose from I figured one would fit! Works like a charm. Happy with my purchase!

Works Great for Multiple Laptops

The heads are labeled with easy to see numbers and lettering which when paired with the charger documentation lets you find the exact voltage and amps needed to power your particular device. The 90W labeling is also important as having to little can result in a device being unable to charge (learned that the hard way). So long as your check your computer specs and they match up with what is listed on this product it should work out just fine. I know that I am happy with the product and think that most other people will be too so long as they do the proper research in advance.

Works, but it is a bit loose

Like I said in the headline.The product does the job it is supposed to do, but I have to lay the cord out in a specific way or else it'll come loose and obviously not charge up my laptop. It's not perfect, but for the price I think it's a good deal.**EDIT** 6.12.22Well it lasted just over a year. I now have to repeatedly adjust the cord until it is set in just the correct position in order for it to work at all. That has been going on for about a week now and it's slowly becoming increasingly more difficult to get it to do its job. So I ordered another one (even though I don't need/haven't used 99% of what comes in the package) before it totally stops working and I will see if this new one lasts longer than my previous purchase.
