I have an ASUS, packbard bell, acer, Legion, and a Fujitsu laptop, with their associated battery chargers.
Does it matter if I connect the battery chargers from acer, Legion or Fujitsu to ASUS and or packbard bell? Are there any dangers or not?
YES.
Probably some others have charging voltage.
For example, 12V, 19V, 20V etc… And or 5A, 8A etc… In the worst case, also different polarity.
It is important that the charging voltage is correct. 19 volts are eigendlich usual here. So first, look what the power supplies give so…
If your laptop needs more power than the power supply gives, then there's a risk in the medium to long term that the power adapter will be overloaded. Does it deliver more power than the original is not a problem. Due to the appropriate voltage, the device only draws as much current as it needs. This is nothing like your home where so well the bedside lamp with 25 as well as the oven with 3000 watts funz as well at the socket.
