Ask Slashdot: Surge Protection For International Travel?

New submitter gaiageek writes: As someone who has lost a laptop power supply (and thus use of the laptop) due to a late-night power surge while traveling in a developing country, I'm acutely aware of the need for surge protection when traveling abroad. While practically all laptop and phone power adapters these days are voltage auto-sensing 100V-240V compatible, most so-called "travel" surge protectors are restricted to either 110V or 220V. Given the space and weight constraints of carry-on only travel, I'd like to avoid having to carry two separate surge protectors knowing I may go from Central America (110V) to Southeast Asia (220V). Strangely, laptop specific surge protectors typically are 100V-240V compatible, but this doesn't provide protection for a phone or tablet that requires the original power supply (can't be charged from a notebook USB port).

Is there really no solution out there short using a 110V-240V notebook surge protector with an adapter to go from a "cloverleaf" notebook plug to a 5-15R (standard US) plug receptacle?

    I hope you realize that the optimal "waveform" from a USB charger is a flat line. There isn't such a thing as "waveform quality" with DC power, which is what USB uses. Ripple, maybe, from insufficient filtering, but not "waveform". That is only an issue with inverters that output AC mains voltage power.
