Review on 🔌 SoulBay 34pcs Universal Laptop Notebook DC Plug Set Jack Tips Compatible with Lenovo, Toshiba, Dell, and Other Major Brands by Carl Movahed

I bought these to use with my Dell 4150 laptop after a power outage. I had a spare Targus power supply that was compatible except for the connector. Well, it didn't work - at first. Dell appears to have had two versions of their 3-pin connector. The 65W PA6 used pin 1 for minus and pin 3 for +, but left pin 2 unconnected. The 90W PA9 I needed for my 4150 has both pins 1 and 2 connected to - and pin 3 to +. Pin 2 identified it as the larger PS and was needed for the 4150. My solution was to insert a short piece of bare #30 wire into the holes for pins 1 and 2 and connect them that way. Now it works. Too bad they didn't make the connector that way from the start. Of course, when purchasing such adapter plugs, it is the user's responsibility to ensure that the voltage and current (or power) ratings of the source and polarity are correct. It would make more sense to have the connector work with PA6 or PA9 applications. The other one I'm interested in is Lenovo's rectangular connector. There is supposed to be an ID resistor between the center pin and the outer shell (negative, inner shell positive). The value of the resistor indicates the power rating of the power supply. I have 170 watts, you need a 1.9 kΩ resistor for this. I just checked the connector and there is indeed a resistor in it, but it's 560 ohms, which is 90 watts. This won't be easy to fix. I was planning to use it with the same Targus 90.W PSU underrated for my laptop. But 90W of power is better than no power. As a result, it loads slowly and doesn't keep up when the laptop is on. It's smaller and lighter and will still be useful for travel. In addition, it can be powered by 12V DC, which is also convenient for traveling. Lenovo, in its infinite wisdom, simply foregoes the 90W AC adapter instead of using it within its limits. I wanted to see what would happen if I faked it as a 170W PSU as I realized it would perform worse.
