You know you should always use a surge protector for valuable electronics, but most conventional power strips are bulky and are either 120V or 240V, not both. So instead of traveling with two power strips for just a laptop, you should consider a special surge protector for your laptop. This multi-voltage model plugs in in-line between the two parts of your power cord and attaches to the power supply with a velcro strap. Once you plug it in you never have to worry about forgetting a surge protector again. It also provides protection for LAN and phone cables.
