For many mobile workers, media hubs offer the ideal solution for dealing with data storage shortage when they run out of space on their laptops, tablets or smart phones.

These devices offer extra storage in the form of SD cards and USB drives despite their compact size. Some mobile hubs even function as device chargers or routers.

Here are three media hubs that can help free your mobile device of memory busting, photos, videos and other files:

The Iogear MediaShair Hub measures 2.8 x 3.7 x 0.6 inches and weighs about four ounces. The device doubles a mobile access point and gets juiced for up to nine hours of operation from its 2600mAh battery which can be recharged from an electrical outlet or a vehicle’s cigarette lighter port. Other mobile devices can be connected to its USB port for charging.

The Kingston MobileLite Wireless weighs in at 3.5 ounces and measures 4.9 x 2.3 x 0.7 inches. Its rechargeable battery lasts for up to five hours and can also charge your mobile device. It sells for $59.99.

The device has USB ports and supports USB flash drives and SD cards. It has no Ethernet port so it cannot act as a router or access point. Of the three devices, the MobileLite is best for managing mobile media. It has apps that run on Android and iOS. It works as a music player, and photo sharing device and supports up to three simultaneous connections. User can also access digital rights management (DRM)-protected iTune file but connection via Safari is needed.
