If you’re looking for an amplifier that can operate on batteries and one that is light enough for you to carry around, you should get a portable amplifier so that you can use it anywhere you want. Having a lightweight amplifier is very useful because you can use it in various ways such as practicising your guitar or other musical instruments wherever you go, boosting the listening volume of your telephone or increasing the audio volume of your handheld devices to make it louder and clearer.
There are many different types of portable amplifiers available on the market but most of them are designed to be lightweight and their main function is to increase volume of the audio signal from your device. You can use it on any devices that support the standard 2.5mm or 3.5mm audio jack such as your mp3 player, mp4 player or even your phone. This is very useful if you want to enjoy your music or videos loud and clear by yourself or with your family or friends.
Alternatively, you can get a small portable amplifier with splitter that gives you at least 3 standard 3.5mm audio jacks so that you can enjoy quality audio silently with your friends or family using headphones. This is perfect if you want to enjoy your music or video in noisy environments such as the restaurants or in any other noisy waiting areas or vehicles such as in an airplane, subway, motorcycle or even in your car when you’re travelling on the highway.
Most people with hearing problems find that they can listen to the audio playback of their devices when using a portable amplifier but you should take care not to turn up the volume too high for such action can damage your hearing. Since running at full volume will cause the batteries to drain faster, you want to lower the volume to the appropriate level so that you can prolong the life of the batteries. It is also highly recommended that you use NiMH rechargeable batteries because you will need to recharge your batteries often if you use it regularly.
