When it comes to mobility in data connectivity, USB-powered data cards, often called USB dongles, are the most preferable devices across the globe. Though smartphones can now provide hotspot support for data sharing over Wi-Fi, the faster connectivity speed of data cards still make them more useful in intensive operations. Huawei is among the leading brands in offering a wide range of data cards in the global markets and this time we have with us its Power-Fi E8221.

What’s in the Box

Huawei Power-Fi E8221 is a mid-range USB data card that comes with standard packaging. The retail package has the Power-Fi E8221 unit and a quick start guide. Though the data card can be connected directly via AC socket, there is no USB adapter inside its box. This means that users have to purchase a separate adapter but it does not matter a lot as the adapter is available in the market for a nominal price.

Its Design

USB data cards are usually available in a thumb drive-like form factor. In the same sense, Huawei also used the thumb drive form factor. The Power-Fi E8221 has plastic built with a compact design which makes it as a mobile device for data connectivity. As the size of the USB data card is quite compact, its weight is also light enough when it comes to mobility.

The rear side of the data card states that it features connectivity speed up to 14.4 Megabit/per second (Mbps). The rear panel is removable and a mini SIM card slot is available for providing data connectivity. In case users have a micro-SIM or nano-SIM, they are required to use an adapter for using their SIM card with the data card.

Overall, the designing of the Power-Fi E8221 is compact and quite similar to other available USB data cards. The black-colored plastic material with matte finish is solid enough for normal usage and users can easily carry the data card in their pockets.

    I have TATA Photon Max 3G WiFi data card which is actually rebranded Huawei E8231. It works great and even it have better coverage capability than most of the data cards and smartphones. I get much faster speed in it. And the best part of it is that- it shows that you’re connected through Ethernet. 😛
