Huawei E8231 3G USB WiFi Data Card 21.6 Mbps

HuaweiLooking for a portable 3G wifi hotspot device? The Power-Fi devices from Huawei are the easiest ones to create a hotspot or access point anywhere. I have been using the Huawei E8231 3G USB WiFi Data Card 21.6 Mbps for the past 6 months and I am mighty pleased with what it does.

This device come with inbuilt Wi-Fi antenna and uses any power source that can power up an USB device like laptop USB port, power mains or a car charging USB unit to turn this device into Wi-Fi Hotspots. This means you can sit back and relax whenever you do not have an internet cable connection and need one urgently.

I use it in my office as I do not want to clutter my desk or wall with modem or cables. This is also a very small device to slug it around anywhere!

Connect it to an unused mobile charger
You can plug the device in any USB adapter which gives minimum power output of 5V and 1.5A It can be plugged into your existing USB mobile chargers, USB Car Chargers, USB Desktop Hubs.

I connect it to an unused mobile charger (that has a removable USB cable) and I can plug the dongle in that adapter. This way I can position this device in various places in my house so that it can catch the best network signal.

Favorite tip: I use this device connected to my power bank whenever there is a power failure (yes, there is such a thing in India!)
