I also have bought the pro cube recharge dock from Hahnel, It recharges two Canon batteries and has a 2.1A USB charger on the back.That's one good looking charger! I travel with a handful of chargers - camera charger(s), AA/AAA/18650 charger, phone charger, laptop charger, GPS charger. And then you have all the associated cables. I'm sure there are better ways to do things. If you ever get your blog up, I'd be keen to hear how you managed with everything. There aren't that many sites or blogs that deal with the mechanics of travel photography - memory cards, storage, backups, editing on the road etc. Yet these seem to be regular topics for discussion on this site.
