Projectors supply a sensible means to move a big show with out the logistics required to deal with a giant TV. With the arrival of LCD projectors, briefcase-sized units turned widespread. With the appearance of LED and DLP know-how, ultraportable projectors can be found that may slot in a jacket pocket.

The Vivitek Qumi Q3 Plus is an instance of the most recent era of ultra-portable projectors, and this one is even battery powered. It retails at $499 within the US, or round £480 within the UK.


The Vivitek Qumi Q3 Plus is roughly the dimensions of an outdated Sony Betamax videotape. That’s 176 x 103 x 28mm for much less mature readers, a remarkably compact measurement for a projector that may throw a picture which is 100-inch (2.6m) throughout the diagonal.

Weighing simply 460g, it’s additionally a really transportable answer that Vivitek claims can function on an inner battery for as much as 2 hours.

The pure decision of the projection is 720p (1280 x 720), although it’ll settle for a 1080p 60Hz sign by way of HDMI.

The outer pores and skin is generally plastic with a metallic paint, although there are numerous metallic grills and a metallic cowl that protects the lens whereas in transit. The assessment mannequin was gold, however different colours can be found together with black, white and crimson.

On the rear are two Kind-A USB ports, helpful for connecting additional storage or enter units. There’s additionally a three.5mm audio-out jack that doubles as an AV-in, a microSD card slot, and a full-size HDMI enter on the rear.

The total specification reads very similar to that of an Android handset, and the similarities aren’t wholly coincidental.

At its coronary heart, this unit is an ARM v7-based Android four.four.2 system, with a customized launcher and subset of Android functions pre-installed.

We’ll discuss extra in regards to the Android facet later, however it’s fascinating to see how these ARM SoCs and Android builds at the moment are turning into all-pervading sensible parts.

The opposite notable points listed below are a tripod mount on the underside of the gadget, and a small plastic foot that may elevate the angle of the Qumi Q3 Plus to clear any close by objects.

The foot is fabricated from a versatile rubberized materials and has all of the hallmarks of being a main candidate for the very first thing which is prone to break.

As slick wanting in look as this gadget is, Vivitek made some design selections that made us scratch our heads considerably.

An apparent one is the choice to mount the inner audio system on the entrance when certainly individuals can be sitting behind the projector? Our logic is supported by the areas of the headphone socket and the distant management sensor, as each are on the again.

Some points appear higher thought-about, like utilizing the distant to regulate focus as a substitute of a mechanical wheel.

The distant is small and cheaply made, however does simply sufficient to navigate the interface. The place issues grow to be tougher is when utilizing the distant to enter Wi-Fi passwords, as utilizing it as a cursor could be very finicky certainly. The plain answer was to make use of a USB keyboard (UK structure), however we found that for no matter cause it will not give us shifted characters. A USB mouse proved to be a extra useful accent, because it facilitated a fast paced pointer to make use of with the display screen keyboard.

As quickly as you flip the Qumi on, the fan inside begins to make a really audible sound. That noise is likely to be drowned out by a recreation however might grow to be irritating throughout a quiet film.

We suspect that the difficulty right here is that because of the small scale of this gadget, the followers are additionally small, forcing them to rotate quickly to get sufficient cooling air by way of. Even with them spinning at full pace, after 90 minutes or so of operation, the Qumi Q3 Plus bought noticeably heat to the contact.
