Promate Bluetooth Speaker, 10W True Wireless Portable HD Speaker with RGB Lights, Bluetooth v5.3, Long Playtime, Quick Music Navigation, Water-Resistance, USB Port and TF Card Slot for iPhone / LumiBar / LumiBar

The Promate LumiBar is a compact portable Bluetooth speaker with a 10W output that covers deep bass and a rich audio spectrum. Custom-designed drivers handle the crisp highs, which is how a body this small produces sound well beyond its size. It is built for HD audio quality rather than the thin output usual at this footprint.

True Wireless Technology (TWS) runs the LumiBar's connection, giving stable transmission, high-fidelity surround sound and quick pairing with no wires involved. A stable link is what keeps a track playing straight through while you carry your phone around the room. Pairing takes moments, so there is little between switching the speaker on and hearing music.

Rainbow RGB lighting on the LumiBar runs across 16 modes, giving plenty of range between a bright party setting and something quieter for the background. The lights sit within a sleek unibody structure, so the effect wraps the speaker rather than showing as a single strip. It makes the LumiBar an accessory for a gathering as well as its sound source.

The LumiBar uses Bluetooth version 5.3 with an operational range of up to 10 metres, so your phone can stay across the room or out on a patio. That version brings rapid pairing, improved stability and efficient connectivity compared with older Bluetooth revisions. Universal compatibility means most phones, tablets and laptops connect without extra setup.

An integrated TF card slot plays music files straight off a memory card and is designed to read various audio formats. Playback controls on the speaker cover play, pause and skip, so the card can be driven without any phone connected. It is the simplest way to keep a fixed playlist with the speaker itself.

A USB port on the LumiBar accepts USB flash drives and other external devices loaded with music, giving multi-mode playback beyond Bluetooth and card storage. Plug in a drive and the speaker plays what is on it, which suits a trip where data or signal is unreliable. A larger library travels on the drive rather than on your phone.

Quick control buttons on the LumiBar handle volume, track changes and RGB light selection, while the touch panel also answers phone calls and pairs devices. The housing itself uses a sleek, lightweight capsule design that drops into a bag or purse for travel and outdoor events. Everything needed to run the speaker sits on the speaker.
