Which power supply is suitable as a replacement?
I'm looking for an inexpensive replacement for this power supply: https://www.amazon.de/...B01M0XW9FX
The way I see it (but I don't know myself very well) the strength and tension are pretty standard. Almost all noname power supplies that deliver 19V / 2.3A / 45W should be a suitable replacement. Am I correct?
For example, this is half cheaper: https://www.amazon.de/...B0828KYHHD
The cheap or even a multi-function power supply should work just like that, right? Please only answer if you are sure what you are telling. Don't want something to go up in flames here.
Correctly you just have to see that the plug fits, there are different sizes e.g. The first has connector size: 7.5x3x1mm
The second but 4.5mmx3mm will not fit
The 19V / 2.37A / 45W and the laptop connection have an outside diameter of 3 mm and an inside diameter of 1 mm.
The 2.37 amps can be higher e.g. 3, xx A, this only increases the power rating, but only max. 45 watts is needed, the value should be higher, that would not be a problem.
The 19 volts should be observed because the electronics in the laptop depend on it, or the converter for lower voltages.
Unfortunately there's no suitable connection in diameter.
Unfortunately, the cheap connector does not fit. Please measure the plug diameter from the outside of your power supply and let me know.
How do you get the connector size?
Can be seen in the first link, in one of the pictures on the left, believe in red.
It says in the description plug size: 7.5x3x1mm
Yes, 7.5 the length, 3 the outside diameter and 1 the inside diameter
To see here.
Sorry, you are right. The one who can read is in advantage.
No prob with 38 years of experience.
You see that correctly: The data of voltage and current of the new power supply must match: First of all the voltage, then the current, which can be at least the same, possibly also larger… And the power comes from the multiplication of both; logically should therefore not be smaller than that of the old power supply.
Whatever the problem is: the plug; of course it has to fit. But a little tip: Buy a new power supply unit with the same voltage and at least the same current, and then go to a repair cafe with the old and new power supply unit: There, both connection cables are cut off and your old cable (which has the matching original plug) connected to the new power supply. Then you have a new power supply on the original plug… And a cable almost twice as long (if you wish; the cable can theoretically be made as long as you want). But the guys in the Repair Cafe can't only do this for you, they can also explain everything:-)
