Output power

The total power of all channels of the speaker system. The higher the power, the larger the size of the room in which the audio system can be used, however, more powerful portable speakers usually have larger dimensions and weight.

Speaker synchronization

The model supports the ability to synchronize the operation of several speakers connected to one signal source. This solution allows you to realize truly stereo sound, improve the quality and power of sound reproduction, and also expand the stereo panorama. The only thing is that both speakers must support the appropriate connection type. Different brands may have their own technologies for combining speakers (JBL Connect, JBL PartyBoost, Sony Party Chain), or maybe a universal TWS.

USB charging port

- 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.
