Hello, I'm looking for a portable powerstrip that meets this criteria:

1. Outputs enough power to charge multiple devices at once (nothing super power hungry - I will mostly be looking to charge kindle, iPhone, iPad, and maybe rarely a laptop)
2. Accepts common voltage amounts in USA and overseas. For example, 110-240
3. Provides surge protection

I have been able to find multiple products that meet 2 of these criteria but not all 3. Does anyone know of a product that exists that meets all 3 needs?

For example, as far as I can tell the Monster Outlets to go line of products accept 110-240 but they do not have surge protection.

The Belkin 3-Outlet Mini Travel Swivel Charger has strong output and surge protection but only works domestically in the USA.

Any ideas?
