I travel to Asia every year. Last year a surge in the local 220v supply killed my laptop AC adapter-charger. Luckily the laptop survived. The APC 100-240v surge protector is compact and easy to carry. I have not tried it in Asia but with APC's name, I would trust it. The only problem is that this suppressor does not fit all Dell laptops. This one fits my Dell XPS 1330 but not my Inspiron M500 simply because in the former the female and male ends are in the form of a triangle but in the latter all in a straight line. I may change my rating to five stars after my next trip to India if it performs flawlessly.
