TabletKiosk eo a7400 Ultra-Mobile Tablet PC Review

TabletKiosk eo a7400The eo a7400 uses two identical 3-cell batteries; one is an internal unit that you cannot access while the other is a hot-swappable external battery. The tablet draws on the external battery first, letting you run on the internal battery while you recharge the external battery or swap in a new one. Together, they offered a combined 5 to 5.5 hours of running time on our anecdotal tests that featured basic tasks and running a YouTube video nearly constantly over that time. You will get longer battery life if you aren’t running video, and you’ll likely experience all-day running time if you keep a spare battery on hand.

Elsewhere in anecdotal testing, the eo a7400 showed can handle basic office tasks, though we experienced more than our fair share of buffering when attempting to flit about YouTube, despite enjoying a strong Wi-Fi signal. You likely aren’t buying such a tablet to perform any heavy lifting, but we suggest you determine if the specific enterprise apps you plan to run on the eo a7400 will run on an Atom-based system.

Performance aside, the bigger drawback to the eo a7400’s functionality is Windows 7, an OS not designed with touch support in mind. TabletKiosk states the majority of its customers are still using Windows 7 and XP and that it expects to offer Windows 8 on the tablet sometime next year.

Like any tablet worth its weight, the eo a7400 supplies two webcams, a front-facing 2-megapixel webcam and a rear-facing 5-megapixel webcam. The front-facing webcam will suffice for video chats and the rear-facing and its impressive (relative to other tablets) 5-megapixel camera takes crisp snapshots.

Like any enterprise tablet worth its weight, the eo a7400 features a TPM chip, which protects encryption keys and digital signature keys to keep your data safe. You’ll need to stay tethered to an Ethernet connection or a Wi-Fi hotspot, however, to connect to the Internet. Unlike other enterprise tablets, the eo a7400 does not offer mobile broadband (WWAN) connectivity. It does have a SIM card slot hidden under the battery, however, and TabletKiosk expects to add a WWAN option next summer.


In the box with the tablet, you’ll find the power adapter, one external battery, the Wacom pen, a neoprene slip case, and a microfiber cloth. TabletKiosk also offers a number of accessories for the eo a7400, from battery chargers and wall mounts to DVD burners and Bluetooth keyboards.  Many of the accessories designed for the older Sahara Slate PC i500 are compatible with the eo a7400.

With our review unit, we received a dual-battery charger, a magnetic stripe reader, a stand, and a shoulder strap. To use the magnetic stripe reader expansion module, you need to remove two small screws to remove the cover of the expansion bay.
