Promate Bluetooth Speaker, 20W True Wireless Portable HD Speaker with RGB Lights, IPX5 Water-Resistance, Long Playtime, Quick Music Navigation, USB Port, TF Card Slot and Top Handle / Spectro-20 / Spectro-20

The Promate Spectro-20 is a portable Bluetooth speaker with 20W of output and specially engineered drivers that deliver impressive bass alongside crisp treble notes. It produces sound well beyond what its small footprint suggests, covering an expansive audio range from one compact unit. That makes it a speaker for a room or a gathering, not just personal listening.

True Wireless Technology (TWS) handles the connection, giving the Spectro-20 swift pairing, surround sound and strong signal stability without any cables. Stability is what stops playback stuttering when you carry your phone to the other side of a room or out onto a patio. Streaming begins as soon as the two devices find each other.

Rainbow RGB lighting runs across four dynamic modes on the Spectro-20, adding a visual layer to a party or gathering rather than leaving the speaker dark on a table. The modes are selectable, so the lighting can match the occasion. Paired with the sleek modern housing, it does as much for the room as it does for the sound.

A built-in 4000mAh rechargeable lithium-ion battery gives the Spectro-20 up to four hours of uninterrupted playtime away from a power point. That covers a braai, a picnic or an evening outdoors on a single charge. Because the cell is rechargeable, the speaker returns to full between uses instead of consuming disposable batteries.

The Spectro-20 runs Bluetooth v5.3 with a reliable working range of up to 10 metres, so the source device does not have to sit next to the speaker. The newer Bluetooth version brings added efficiency, rapid pairing and a stable connection across that distance. Universal compatibility means phones, tablets and laptops connect without extra setup.

A built-in TF card slot and a USB port let the Spectro-20 play music files directly with no phone connected. Load tracks onto a TF card or a USB flash drive, insert it, and use the playback controls to play, pause and skip through the collection. It is the fallback wherever there is no signal or no device to spare.

A soft touch button panel covers volume, track management, RGB light mode selection, call answering and device pairing straight on the speaker. The housing uses a compact lantern-style shape that is light enough to carry in a handbag or a backpack. Between the two, the Spectro-20 is built to be picked up and used rather than installed.
