All portable karaoke units are self-contained. They usually have their own speakers and amplifiers, some in fact come with their own monitor to display the lyrics. These karaoke machines are usually user-friendly and convenient. Two major considerations with portable machines are sound quality and power because of its self-contained nature. Remember that with component or non-portable units you can always upgrade the power and improve quality as and when necessary but with portable karaoke machines you are stuck with what you purchase. If you want something better you have to replace the entire unit.
Things To Consider When Purchasing Portable Karaoke Machines:
Usually the wattage clearly defines the volume, clarity and sound quality of the karaoke machine. You will find portable units that deliver as little as 5 watts up to a whopping 300 watts. Remember that a 5 watt increment isn’t substantial but a 15 watt increment is. Hence, when trying to decide the optimum output range, look at increments of 15 to 20 watts. Thankfully, portable units with around 60 to 90 watt output come for less than $200 and are quite reliable.
The crux of any portable unit is its sound quality because they come with built-in speakers. Quite naturally, expect an average experience from portable units. If you are truly interested in superior sound quality, get a portable unit that can interface with separate speaker components.
All portable units feature some sort of monitor onboard to display the lyrics. This is the defining feature of a portable karaoke machine. However, it is not necessary that the screen will play videos. Usually lower end portables have a tiny screen that can read lyrics from karaoke tracks but can’t play videos or images in the background.
