The E1 LED projector is the size of the palm of a hand and weighs merely 300 grams. Its sandblasted aluminium housing and rounded edges render the unit handy and slip-proof. A micro USB port is available for the connection of Android devices. The projector is operated intuitively via the lens cover: if it is shifted, the device turns on. The unit includes an internal rechargeable battery sufficient for five hours of operating time.
