On the notebook power adapter output current and voltage issues
This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
This current is the maximum current value of the adapter output,
Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator.
3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating.
Conditional or buy a large number of good current.
