Ok, so I am a sucker for electrical travel devices which are multifunctional. Here we have a Belkin Mini Surge Protector which has 3 plugs, as well as 2 USB ports for charging such items as mobile phones, iPhones, iPods and anything else that can be charged via USB. I bought one of these items before a safari earlier this year, and I love that I can leave my dedicated USB chargers back at home and just use this single device. Highly recommended. B&H has a good deal on them here.
