Advantages: Compact and Portability Disadvantages: Price
This USB Power Adapter is a must accessory to have if you have any kinds of iPods. As you would know, when you buy an iPod, you will only receive the iPod itself and the link cable. This means the only way you can charge the iPod is through the computer. However, this is disadvantage for many reasons since you would need to make sure the computer is on when charging. Because its USB charged, it takes quite a long time to charge it to full.
This USB Power Adapter deals with all of the charging problems and many others. The size of the power adapter is very compact, with its dimension of 4cm by 4cm (estimate and could be different when bought from different country). It is also not so heavy for portable use.
Also, you can change the adapter itself to European, Asian or wherever with great convenience. All you have to do is slide it ...
Advantages: Price. Disadvantages: You have to destroy the box to get the unit out.
Trust 4PortUSB Hub.
Basics first I suppose. For the non techies out there, this device is used to connect up to four USB devices to your P.C., such as digital cameras.

The box contents are as follows.
USB Hub
USB Cable
Velcro Tape
Protective Carry Case
Multi Language User's Manual.
The hub is a small black unit with single connecting point on the back and four USBports on the front for your USB peripheral such as digital cameras and MP3 players. A really big well done for Ciao for not putting a picture up, as I did provide the web address so that they could. The dimensions are 75mm ...
Advantages: Works straight out of the box, Easily Portable Disadvantages: Short connection cable, Only gives you 3 more ports
I bought this Hub for my Dell Laptop around a month ago now. It is a good product, and was particuarly easy to install. It works straight out of the box and the computer installs the drivers for you, so there is no need to install any extra software. I dont receive any noticable performance drop of something that is connected through the HUB, although my Wireless mouse which uses a USB connection is for some reason not recognized when used through the Hub. This could be a problem with the mouse, although I have had no problems with it so far (It is a Logitech v500 Cordless mouse). I would recommend the product for someone who is running out of USBports on a Laptop computer, although I think there are better products out there if portability is not a factor (ie a Desktop computer). Another point worthy of note is that it has a very short ...
