I thought my previous recommendation for travel power adapter was good. I'd been using the "Swiss Travel Products" adapter for the past 5-6 years and thought it was brilliant. But I've found something even better!
The Satechi Smart Travel Router / Travel Adapter with USB Port adapts to fit into four (actually five) of the most common plug configurations used around the world and features four different modes for your wireless networking needs.
Why is this adapter so great? Well, it is an all in one solution for travel. For a traveler, it acts as
- Plug adapter for any popular configuration to any other
- USB charger with TWO 5V 2.4A jacks--this is enough to charge any phone or tablet quickly
- WiFi router to allow you to share a single WiFi connection among multiple devices/users; create a WiFi connection for your devices if there is only an ethernet connection; extend a WiFi signal to reach when it is needed (I've had hotel WiFi that only works at one spot in the room)
Best part? it is all less than $50 which I think is amazing value for what you get. I've only started using it and all has been well. From reading the various reviews online, there is no reason for me to believe that it won't be reliable longer term.
