LCD display. Such a screen makes device management more intuitive: it can display the operating mode, equalizer settings, battery level, etc.
- Handle / strap.
The presence of a handle or strap makes wearing the speaker more comfortable. So the handle is used mainly in large stereo speakers and makes them look like boomboxes (
radio tape recorders) of yesteryear. The strap can be used both for large speakers and for miniature ones, which allows you to hang them on your hand, on elements of a backpack, etc.
-
Flashlight. Such a function most likely will not replace a high-end specialized flashlight. The power of the built-in flashlight is usually enough to illuminate at least a distance of 2 - 3 meters, and models with a bike mount (see above) can even play the role of a headlight (although, again, they are inferior to specialized bicycle lights).
—
Carabiner A latch-like device that allows you to attach the speaker to items of clothing, backpack straps, etc.
-
Bike mount. A special device designed to fix the speaker on a bicycle - usually on the handlebars, at the user's fingertips. Such models are often complemented by a speakerphone function that allows you to talk on the phone without taking your hands off the steering wheel.
Theoretically, a
higher capacity allows to achieve greater battery life, but in fact, the operating time also depends on the power consumption of acoustics — and it can be very different, depending on the characteristics and design features. So this parameter is secondary, and when choosing it is worth paying attention not so much to the battery capacity, but to the directly claimed operating time (see below).
