An AC to USB charger is your on-the-go charging solution. This is not a new technology and may seem like an obvious solution to some, but I get a lot of emails from people looking for a wall charger for their MobiBLU Cube or their Samsung Z5 for when they are traveling and don’t have access to a computer. So for all you USB-charging-MP3-player-toting fools, this one is for you.
There are many of these types USB wall chargers out there, but I particularly like the compact size and fold up design of this one. It is made by Sima (SUP-USB) and includes a car as well as a home charger. They can both be obtained for under twenty-five bucks at many B&M and online electronics retailers
Sima also makes a universal adapter that will replace most AC/DC adapter with the included adapter tips. Also included is a car adapter and Europen plug (not shown) for use on your holidays across the pond. I was tipped off by an iRiver fan that uses this particular adapter as a spare. It is a little pricey, but it will cover almost all of your AC to DC, DC to DC, and US to EU needs.
