As for a surge protector - any will likely do for home use and for mobile
use - look for one at your local store for laptops. It will be for laptops
mostly because it is portable.

Those plug-in surge protectors do not even claim to protect
elecctronics from they type of surge that typically causes damage.
Don't believe it? Then get its numerical specifications that list
protection for each type of transient. They don't claim such
protection. They do make the classic WMD claim. IOW they would have
you assume all surges are same.

Meanwhile, another problem with these ineffective protectors:

How to identify an ineffective protector? 1) No dedicated earthing
wire. 2) Manufacturer avoids all discussion about earthing.

Effective protectors make that essential connection to earth.
Manufacturers with more reponsible brand names include Cutler-Hammer,
Leviton, Intermatic, Square D, Siemens, and GE. Effective 'whole
house' protector is sold in Home Depot, Lowes, and electrical supply
houses. Never saw an effective protector nor reponsible brand names in
Radio Shack, Sears, Staples, Wal-Mart, Circuit City, or the grocery
store. How do you identify these ineffective and grossly overpriced
products? Where is the dedicated earthing wire? Protectors hyped to
the naive promote word association as science: 'surge protector'
sounds like 'surge protection'. Therefore it must be same.

No earth ground means no effective protection - even for the laptop.
Effective protection means an earth surge does not overwhelm protection
already inside the laptop.
