I like to travel light. On recent(ish) trips to Thailand, Japan and Egypt I've only taken carry-on luggage. I also don't like clutter in my flat. Combine these two things and you come to one, inescapably obvious conclusion:

Power cables suck.

Thus over the last few years I've ensured all my new gizmos are rechargeable via USB which, combined with a collection of small USB to wall plug / car cigarette lighter adaptors, means minimum cables in my luggage and my flat.

For example (bottom of pic), here's the cabling required to charge my X-Mini II travel speaker (mini-USB) on UK trips (noting the plug adaptor can be used for all my other devices too):

A key discovery in achieving this was that even if the device, like my camera, won't natively charge over USB, there are always third party USB battery chargers available (I recommend Ebay) for very little money.

Alternatively, if you have your laptop with you, you can charge everything through that (some laptops will even leave a USB port live while sleeping for this exact purpose). Admittedly you'll have to take the laptop lead with you, but you can always buy a local figure of 8 or kettle lead if you want to avoid taking the adaptor for that (again Ebay is your friend - I got a US/Canada one for $3CA, delivered).

If you're travelling to more than one country you'll need a multi-adaptor, but there are some, like the green FujiFilm one pictured above, that cover every continent, so even that isn't to bad.

The beginning of the end for scenes like this?

Here's hoping.
