Motel units never have enough power outlets for a switched-on guy like me. That's why I carry a small powerboard in the car: it has a pair of three-pin Australian 240 volt outlets and four USB charging ports for a total of 2.1 Amps. Currently* it's charging the iPad Mini, iPod Touch & its battery case plus a 12,000 mAh lithium-ion battery pack.
