Charging used to be so different before USB arrived. Your various gadgets all have their own chargers and each charger terminates with an A/C plug that you insert to your electrical socket. But post-USB, more and more devices are relying on the USB jack as the sole means of charging said devices.
Charging by USB is not really a big problem. But it does have its pros and cons. As an advantage, USB cables are thin and since it terminates at both ends with very small jacks (the USB jack and whatever proprietary jack is used by the device – although a mini-USB jack seems to be gaining traction among manufacturers) it’s so easy to transport. But the negative point against it is that you still need an A/C adaptor to charge if you want to use an electrical socket. These are relatively bulky. It would be cool if there are other solutions to USB charging.
A solution has indeed been thought up by the manufacturers of the U-Socket USB Wall Plug. This is a really cool electrical hardware that recognizes how much USB has entered our daily lives. The U-Socket USB Wall Plug offers both socket options. It has a two three-pronged electrical outlets but the cool thing is that it also has two USB charging ports that can give off up to 2.1 amps of power on each port. The manufacturer, Fastmac, guarantees that these ports will charge almost all devices including all mobile phones including the iPhone 4. A bit of a warning though, this outlet is not your typical electrical outlet that you just put in without any fuss. The USB Wall Plug will require a bit of assembly before you can mount it. But it’s a minor inconvenience. If you have so many gadgets that charge through USB cables then this is a great timesaver.
