On the tablet itself, you've got a USB 2.0 port, a micro-USB socket for charging, mini-HDMI, a headphone port, micro-SIM slot and a full-size SD reader.
The bags have a battery built in, along with a complete charging system: Apple connector, Micro- and Mini-USB connectors and an on-board USB port for charging up to 4 devices at once.
On the back, two more doors flip open to expose a mini-USB port for charging (still no micro) and a mini-HDMI socket to get a direct, digital feed of content.
