Can i use my daughters laptop mains lead to charge mine?
You need to examine the labels on each charger. The key aspect is the output voltage. Ideally this should be identical but in reality there is a bit of tolerance built in. You are highly unlikely to have problems if the voltage on the replacement unit is a volt or less higher than the original. You can be a bit more adventurous if the voltage of the replacement charger is lower than the original since at worst it is not going to work (rather than damaging anything), so it is worth trying if it is up to a couple of volts below the original. The other factors to consider are the current rating and polarity. The current is the figure followed by A or mA (1000 mA is equal to 1 A) and ideally the replacement should have the same or higher rating. It doesn’t matter at all if the rating on the replacement in a _lot_ higher than the original since the laptop will not draw more current than it actually needs (the figure is a maximum rating). If the current on the replacement is slightly lower t
