The Acer K138ST is simple in design, with a sort of oblong rectangle shape. Starting in the front, there is the fixed, manual focus lens, complete with a lens cap. That is a feature I appreciate and take note of, as the two pocket projectors I recently reviewed did not have a lens cap, and therefore no protection from dust. Also in the front is one of the fans, and an adjustable foot centered underneath to adjust tilt, giving the projector a little more placement flexibility than the AAXA M6, its direct competition.
On either side of the K138ST are the stereo speakers. At the back of the projector is the inputs and connectors panel. Though simple, it has all the connectors you’ll need for entertainment, and even for presenting with a computer. The top of the projector has, of course, the control panel and indicator lights for Temp and Lamp. Now, let’s explore that back panel more in depth.
