Hi, my Dell XPS 9560 came with a 130w power adapter.    Is it possible to use a  Dell 90w power adapter?   I would like to get something a little slimmer and lighter for travel.    I have a Dell XPS 13 with a 45W and tested it with my XPS 15.   It charged but at a much slower pace.   I'm not sure if this is safe or not.   They both produce the same amount of amp output.   Thanks.

are you sure the amps are the same? Because if so the voltage is different and you won't be able to charge. As long as you use the same voltage but the amperage is lower it will charge but slower. By the formula Power =  Voltage x Current, for example if you have a 40w charger at 20v the current will be 2 Amps

A lower wattage works fine. It's just gonna charge slower, that's all.

As long as the voltage is similar and not higher, it should be safe. Having lower amps would just charge your XPS 15 slower due to less current traveling to the battery. However, when using such chargers, don't do high load work as your XPS 15's battery would discharge quicker than it is charging, which can slowly deteriorate the battery.

Hi, sorry for the delay.  Thanks for all the advice.   I'll double check the amps again.   I know very little about electricity.  :-)
