I bought a new second hand computer with probably the wrong adapter. It's a 30 euro laptop with Windows Vista on it. The girl who sold it to me told me you have to wiggle the plug a little and then it charges. It does. But I have an old adapter from my old crashed laptop which plug fits perfectly into the slot. Also if I look at the back side of the laptop, the current there is exactly the current on my old charger. So I am 99% I can try that old charger on that newly bought second hand laptop without the risk of blowing things up, right?
To rephrase the devices are:
- Newly bought second-hand laptop: 19V 3.42A
- The non-fitting adapter I got with it:23V 2.50 A
- My old adapter I still got from another laptop: 19V 3.42 A
Question 1: Should I try to use my old adapter rather then the non-fitting thing I got with it?
Question 2: How come the non-fitting adapter does charge that?
