The Optoma is probably the closest any other projector has come towards matching the all important brightness specification and like the Adapt 305 the Optoma PK301 is also 45 lumens when run from a battery.
Whilst the Optoma PK301 pico projector and the Adapt 305 pocket projector are very similar products in terms of picture quality and dimensions there are some differences.
The major differences between the world's best pocket projector, the Adapt 305 and the Optoma PK301 LED pocket projectors are mainly price and the levels of equipment included in the box.
- The Optoma PK301 and the Adapt 305 are approx £350 although the Adapt also includes a tripod and an iphone cable (£41) as well as 4gb onboard memory which effectivly brings the Adapt 305 price down to well below the £299 bracket when all the accessories are included and you take account of the cost of a 4gb micro SD card.
- The Adapt 305 also includes a remote control (not included in Optoma PK201 and PK102)
