Best Portable Speakers with Power Bank Function

The Chinese company Tronsmart seems to be striving to become the Xiaomi of the portable acoustics world, because its speakers are often called “JBL killers” in reviews. And this is not surprising: Tronsmart acoustics are at the level of fakes that are sold in underground passages, but are not inferior to the original JBL in sound quality and even surpass them in functionality.

The Element T6 Plus model supports modern fifth-generation Bluetooth and is equipped with connectors for a flash drive, microSD card, and a USB type C port. Thanks to it, the speaker can not only be charged from a PowerBank, but also distribute energy to a dead smartphone.

Element T6 Plus is an improved version of the popular Tronsmart Element T6 model. The model captivates with a winning combination of minimalism and unusual functionality. Externally, it is a small barrel covered with rubber, ABS plastic and aluminum buttons. At the top of the Tronsmart T6 Plus you will find a stylish, convenient and multifunctional aluminum control wheel that allows you to control the volume, basic player functions and switch to call reception mode. The case is protected according to the IPX6 standard, that is, it is not afraid of dust and splashes, but it is better not to put it under water.

The Tronsmart speaker is packed with two independent high-frequency emitters and two full-featured 20-watt stereo amplifiers. It operates on the basis of its own SoundPulse audio technology, which allows its compact speakers to deliver an unusually deep and powerful bass. At maximum volume, the speaker produces a bass that is not childish and begins to “walk” along the table. Fortunately, it also has a horizontal position, so you can simply put it on the table sideways. I especially liked that the speaker evenly distributes sound in all directions, the stereo effect is memorable. Well, it is convenient that instead of an overly complex equalizer, the Element T6 Plus has just three sound switches. Vocal sounds smooth and neutral, 3D Deep Bass creates a wide stereo bass (ideal for movies), and Extra Bass is designed for home parties. If we talk about the overall sound quality, it is approximately on the same level as the excellent JBL Xtreme 2. Only Tronsmart has a slightly softer character. And the price is 3 times lower.

The 2024 debutant from the Soundcore brand is a powerful portable speaker with wireless connection via Bluetooth v 5.3. It has a 50-watt subwoofer, a passive radiator, and a pair of 15-watt speakers. In normal mode, all together they produce up to 60 watts, and with active bass amplification (BassUp function) - as much as 80 watts.

The mobile app for Soundcore Boom 2 offers the ability to adjust the equalizer, and thanks to TWS synchronization technology, over 100 speakers can be combined into a single acoustic system at large parties.

The 3100 mAh battery should provide up to a day of music playback (at 50% volume) without being connected to a power outlet. The charging process will take 4 hours, and a modern USB C interface is offered for power supply. If necessary, the battery capacity of the portable speaker can be shared with a smartphone or other mobile gadgets.

The model's body is made of plastic and has good IPX7 water protection - you can enjoy music in the rain or near water (by the pool, on the beach). Other features include a built-in microphone for speakerphone, an LED panel with support for 7 different lighting effects in time with the music, and a carrying handle.

Soundcore Boom 2 is a balanced portable speaker that is suitable for parties and simply for those who appreciate powerful, bass-rich sound.

The fifth edition of the JBL Charge portable speaker with the function of charging energy consumers from the outside was “rolled out” to the public at the very beginning of 2021. It sounded even more beautiful and began to stay “afloat” longer.

The speaker has a slightly refreshed design and improved sound quality. The model boasts two passive radiators, one bass "low-frequency speaker" and a high-frequency tweeter. Together, they draw a clear and clean sound track with rich bass. The model communicates with the smartphone via the Bluetooth 5.1 wireless protocol. "Under the cover" of the rubber plug in the barrel-shaped body of the speaker, there is also an AUX output.

The model is protected from external influences according to the IP67 standard, maintaining full functionality when dropped into water. The JBL Charge 5 is powered by a high-capacity 7500 mAh battery. It provides up to 20 hours of continuous music playback (at medium volume). At the same time, you can charge your smartphone from the battery.

Using the PartyBoost function, it is possible to create a single large audio system with other JBL speakers. At the same time, two mobile devices are linked to the model. You can control the playback of audio tracks from them alternately. In general, the "five" did not bring anything revolutionary new, but it did strengthen the ratings of the popular JBL Charge family.

The Sony X-Series SRS-XG300 is a true party king, pumping up large dance floors with clear sound and deep bass.

The speaker is assembled in a durable case made of durable ABS plastic, which has dust and moisture protection according to the IP67 standard. The dimensions of the portable speaker are relatively small (138x318x136 mm), but its weight is about 3 kg. At the ends of the cylindrical case of the model, you can see the active LED backlight Ambient Illumination, shimmering in different colors to the beat of the music. The operation of the backlight system is supposed to be controlled through the proprietary mobile applications Sony Music Center and Fiestable.

The speaker's sound is provided by six acoustic emitters at once: two woofers with a non-circular diaphragm of optimized shape, a pair of 20 mm tweeters and two passive resonators. The model sounds especially bassy in Mega Bass mode. The Sony Party Chain function allows you to combine compatible wireless speakers into a single acoustic system, and the Sony X-Series SRS-XG300 also supports the simultaneous connection of several mobile gadgets.

To pair with signal sources, the model uses a wireless Bluetooth v 5.2 interface with support for popular SBC, AAC and LDAC codecs. The speaker is powered by a built-in battery with a declared autonomy of up to 25 hours in a row. The battery of the portable speaker can share its charge with external devices, which is useful in nature, far from electrical civilization.

In the line of Bluetooth speakers from Harman Kardon, the Go + Play 3 model is one of the flagship solutions, which will become an interior decoration when used at home. The design and coloring echo other branded products, including, for example, the Onyx Studio 8. The plastic case is complemented by a touch control panel made of tempered glass and an aluminum handle for carrying.

The portable speaker is equipped with a subwoofer, which is directed downwards and is responsible for reproducing expressive low frequencies. Plus, a passive radiator is provided to enhance the bass. Two pairs of midrange and high-frequency speakers are responsible for the overall spectrum. The total power reaches 160 W, while listeners will not only have a large volume reserve, but also a balanced frequency range with a natural sound stage and good separation of instruments and vocals.

The model does not support synchronization with a mobile application, so flexible settings are not available to the user. But automatic sound calibration is implemented here every time you turn it on: it is stated that the acoustic system selects the optimal parameters taking into account a specific room or environment.

The built-in battery will provide up to 8 hours of autonomous operation of the speaker and is ready to function in power bank mode. The charging process should not exceed 3 hours. It is also worth highlighting the presence of a pair of microphones for speakerphone and support for pairing with two devices at once - Multipoint.

The disadvantages of the model are the high price tag and heavy weight (4.7 kg). In any case, if you need stylish and powerful portable acoustics that do not require special sound settings, then the Harman Kardon Go + Play 3 is definitely worth considering.
