Expand the storage capacity of mobile devices is a user needs. If your device has a memory card slot, this is quite simple. But with the phone, the tablet does not support removable memory cards such as iPad, Nexus 7, iPhone, Galaxy Nexus ... the problem seems to be more difficult. We have two solutions: one is to buy a USB cable USB OTG and high-capacity memory card or two is to use the external hard drive storage support wireless connection. So in terms of convenience and easy operation, the hard drive wifi solution is somewhat more prominent and easier for ordinary users. Finally, the main character in this article is Air Drive, a portable hard drive that supports wireless connection that PQI debuted recently. PQI Air Drive is a mobile storage device with compact size a business card size 85 x 54 x 8 mm and weighs only 55g. It has two strengths that can change the storage capacity with built-in SD memory card slot and you can easily replace the memory card with different capacity. Also Air Drive WiFi with the ability to connect to 5 devices at the same time, the built-in battery so it can work 5 hours continuously. Compared to other wifi portable hard drive like Seagate GoFlex Satellite and Kingston Wi-Drive Mini Air Drive lighter, storage capacity can change easily. How it works of all three are the same: its own wifi and wireless mobile devices to access the data. Uptime is also quite similar when all three are published on the theory of five hours. Design PQI Air Drive design has a beautiful square and compact. The shell is made of alloy with a matte black along with metal rings, all made looks luxurious and scratch-resistant. The compact size of the device makes holding and carry with you quite easily, if you want to be able to put in a pocket or wallet. The entire front of the device no more than the PQI logo in the upper right corner of the back lot of words with information about the serial, and the symbol of light. Next to no details at all. The left edge of the device we find the USB cable, play data transfer as well as charging the battery. By PQI no bundled charger so you have to charge through the USB port of the computer. If not in use, the cable connecting the device was hidden pretty neat in itself. Cable has a short point is, when plugged into a bit uncomfortable. If PQI microUSB port here and bundled cable connection better leave, and will also take advantage of the free space for bigger batteries. Bottom edge of the memory card slot with plastic cover. According PQI Air Drive supports SD / SDHC card with a maximum capacity of up to 32GB. However, I hate 128GB SDHC cards, it is still getting up and running good.

Actual time using the battery Air Drive well, consider this film continuously for several hours, the result is a new battery after 4 hours and 30 minutes off.
