As per my other post.   If you look at OCM and click on plus sign by "before 2014"  you will see below.  Machines originally came with either 45 or 65 Watt chargers.  You can use higher wattage if you want.  The laptop will only draw what it needs.  You dont need to change chargers based on wattage of battery.  The 65 Watt charger will charge faster than the 45 Watt charger.  The bigger the battery the longer it will take to charge.

Thank you for your prompt reply. Am I correct in assuming that it is safe to use a higher wattage adapter if a I need to plug plenty of USB hardware for any X series laptop / tablet without a docking station (eg 90 watt)?

Yes as per OCM you can even use the 170W charger if you want to.  The laptop will only draw what it needs.

You're welcome!  I would recommend if you use larger battery pack you use at least the 65 watt charger over 45 watt just so it charges faster.
