LCD display. This screen makes device control more visual: it can display the operating mode, equalizer settings, battery charge 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 similar to boomboxes (
cassette 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. This feature likely won't replace a high-end, dedicated 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 bicycle mount (see above) can even play the role of a headlight (although, again, they are inferior to specialized bicycle lights).
—
Carabiner/suspension A device in the form of a latch that allows you to attach the speaker to items of clothing, backpack straps, etc.
—
Bicycle mount. A special device designed to mount the speaker on a bicycle, usually on the handlebars, at the user’s fingertips. Such models are often complemented by a hands-free function, which allows you to communicate on the phone without taking
...your hands off the steering wheel.-
microUSB. One of the miniature versions of the USB connector, still popular in portable gadgets, despite the emergence of the more advanced USB C. It has relatively limited capabilities (in particular, it is inferior to USB C in terms of the maximum possible charging power), but this point is rarely critical. At the same time, there are a great variety of cables and chargers for microUSB.
-
USB C. A relatively new type of USB connector that is actively gaining momentum. Like microUSB, it has miniature dimensions, but has a more convenient double-sided design and advanced capabilities, in particular the ability to transmit higher power, which has a beneficial effect on charging time.
