The battery in the MobileLite G2 can be recharged with a USB cable connected to its micro-B USB connector. It can be charged whether it is turned on or off. The red battery indicator blinks to indicate it is being charged.

SD Card Reader

When the MobileLite is turned off, it will operate as a USB 2.0 card reader. Plug a USB cable into the mini USB-B port and connect to a computer. SD cards insert fully into the slot and do not protrude, making it easy to transport the device with a card inside. The card can be ejected by pressing it.

As a card reader the MobileLite G2 transfers at about 20 MB/s read and write speed. It is not a replacement for a fast USB 3.0 reader when transfer speed is important. USB devices connected to the USB port on the MobileLite transfer at up to 35MB/s read speed. This speed is limited by USB 2.0.

It is possible to plug a USB card reader into the USB port on the MobileLite to read a CompactFlash or other memory cards formats via WiFi.
