How should I protect my laptop while traveling in southeast Asia? I will not be staying in star rated (ie: 1-5 star) hotels. I will often be in more rural areas where there are no grounded outlets and dodgy voltage coming in. My laptop charger specifically says "Connect only to grounded outlet". Oh and one more fun fact, often times a 3 pronged outlet isn't grounded, it just has 3 prongs for adapter purposes! Is there a way to safely charge my laptop in these areas?
And finally, even in Bangkok much of the outlets are not grounded (again despite how many prongs are on the wall's outlet), so this really applies to all of south east Asia, not just the rural areas.
Some people here recommend buying higher grade power supplies with voltage regulation (all areas). I'm unsure of whether or not this is simply hearsay or actually an appropriate solution.
