Projectors are an incredibly functional tool in the workplace, classroom or even home environment but the reality is that they often have to be transferred from room to room depending on the needs of the user.
Fortunately, portable projectors are readily available and come in a range of makes and models with various technological options. Here are some basic guidelines for buying a portable projector.
6 Elements to a Portable Projector
1. Projector Weight
If you’re going to be lugging the projector from place to place on a daily basis, then the first consideration should be the weight of the product. While the projector should be lightweight – about 2kgs – it should also meet all your other viewing requirements.
2. Lens Zoom
When using a projector in various room settings, elements such as the screen size and placement are out of your control so it’s imperative that you can adjust the lens zoom. This means the projected image size can be controlled without physically moving the projector. However, some of the more compact projectors don’t have a lens zoom so it all depends on your particular needs.
The light outputs are determined by the lumens so projectors with a high rating for lumens have a brighter light. The brightness needed really depends on the size and configuration of the room so the larger the room, the brighter the light needed. For much darker rooms, a bright light is not a necessity.
4. Keystone Correction or Lens Shift
These two functions allow for the adjustment of the image in different ways – something you will need when moving a projector around. Keystone correction allows you to correct any distortion by digitally adjusting the image to hit the screen perfectly. Lens shift allow for mechanical adjustment of the lens angle by shifting it up, down or sideways maintaining 100% of the resolution - making it the preferred choice. Portable projectors tend to come with keystone correction, but there are various options available.
5. Wireless Option
This is an increasingly popular option and really a key consideration when investing in a portable projector. The wireless option will allow you to project photos, videos and presentations wirelessly – all that is needed is a wireless projector app for iOS or Android that is compatible with the projector. This also mitigates the need to assess the outlet options of a projector.
6. Running Costs
This is a major factor when purchasing a portable projector, or any alternative, because the initial cost of a projector fades in comparison to the long-term running costs. An inexpensive projector might require costly maintenance and bulb replacements. The projector’s light source can be one of three options – standard lamps, laser or LED. Both standard lamps and LED require bulb, and while they do last several thousand hours, the brightness diminishes as they reach the end of their lifespan and are extremely costly to replace. The laser option, however, requires no bulb replacement so it’s definitely worth taking this initial cost into consideration.
The advanced technology available makes portable projectors a really useful and fun investment. They can be compact enough to fit in a handbag but powerful enough to share images with a group of people. They are ideal for off-site meetings, frequent travel, and even a movie night at a friend’s house. Just make sure you know your requirements going in and compare these with the technologies available.
