TP-LINK has announced a new pocket-sized wireless router that is affordable and useful. Measuring up at just 2.5" square and a depth of less than 3/4", the micro-sized router really can be taken with you while on the go, whether that be traveling or just running across town. The device is smaller than a credit card.

The device is said to provide 150Mbps wireless access speed and can be powered by a USB or external power supply. It is said to be powerful enough to deliver that speed inside an average-sized room. While you won't be winning any performance awards, it's perfect to get a smartphone, tablet, or other device onto a single, wired internet connection.

The TP-Link Nano can be used to create an instant Wi-Fi hotspot by plugging in an Ethernet cable from your existing network or modem. It also functions as a Wireless Router, Range Extender or Wireless Bridge. The stylish cube design is small enough to fit into your pocket and plugs right into an electrical outlet without the hassle of using a power cord.

Key features are as follows:

• The world's smallest router - 2.5" x 2.5" x 0.7"
• Wireless speed up to 150Mbps
• Compact and portable, small enough to take on the road
• Powered through a micro USB port by an external power adapter or USB connection to a computer

• Supports AP, Router, Client, Bridge and Repeater operation modes
• Supports WEP, WPA/WPA2, WPA-PSK/WPA2-PSK encryptions
