I have checked everything needed regarding compatibility with my laptop. Even so, it makes my laptop very slow and the battery does not charge.

After a year and a half it burned, I took it for repair, they returned it to me after 2 months, it worked for two days and burned again

This specific charger was purchased for a 11-year-old Dell N5110 laptop with an i7-2670QM processor, after the 4th charger broke (I now change them every two years). Except for the angled connector, which may be bothersome although it fits perfectly, it is excellent. It does not increase the temperature, it has no noise at all, and it works flawlessly on the laptop, which does not have a battery, without any issues. The BIOS recognizes it perfectly.

30/6/22 received at €12.99 for my failed Dell Inspiron 14z 5423 ultrabook from 2014, which is only compatible with Windows 8.1 and can be booted with any other upgrade.
Recently, the original charger stopped working, I intervened with €0.80 on the capacitors :( but I couldn't recover it, and after positive comments, I ordered the Akyga 90W 19.5V 4.62A without the AC 220V input cable. It charges the battery normally and does not increase the temperature.
16/11/22 it is working perfectly.
I will inform about any negative incidents.

So I have had it for almost 2 months. In terms of power, it is the same as the factory one, that's why I got it in the first place. It doesn't raise temperatures and the plug fits just like the factory one. Akyga proudly states on the box that it is green and consumes less energy. I haven't measured that to know for sure.
Note: I only received the charger itself as shown in the picture. Without the cable that connects it to the socket. So I used my own cable (those are everywhere). Keep that in mind.
Note 2: Its plug is in a "G" shape and not straight as shown in the picture.
Note 3: Before buying any laptop power supply, make sure it has the same characteristics as your factory one. Same voltage and wattage. Otherwise, you will have malfunctions in your computer and if you are unlucky, it may even burn it!

It does not charge the laptop, it simply maintains the battery percentage it had. Additionally, the laptop's speed has dramatically decreased.

Awesome value for money charger that has nothing to envy from an authentic Dell. I plugged it into an XPS m1330 that I use as a server and it's on 24/7. It works flawlessly, without raising the temperature even though it's inside a poorly ventilated cabinet. I don't have an opinion on its durability over time
