Portable speaker with 25-watt amplifier

The GravaStar Supernova Battle-Worn Yellow is a portable Bluetooth speaker built around a 25-watt amplifier. Professional acoustic algorithms drive real stereo sound without distortion at maximum volume. The distinctive battle-worn yellow finish and detachable handle suit listeners who want rugged style for outdoor use.

Up to 28 hours playtime and 100-foot range

Wireless connectivity delivers a range up to 100 feet for flexible placement. The battery provides up to 28 hours of playtime on a single charge. At 4.4 weight units the unit remains portable enough for camping trips or garden parties without constant recharging.

Three RGB light modes with EQ pulsing

Eight RGB colours cycle through three light modes including an EQ pulsing mode that reacts to the music. The integrated LED table-lamp function adds ambient lighting for evening gatherings. TWS pairing lets two speakers link for wider stereo coverage when a single unit is not enough.

Questions about this item

How do I pair two Supernova speakers for stereo sound, and what step do people miss?

Press the TWS button on both units within seconds of each other; the common mistake is waiting too long between presses so the link times out.

What part of the Supernova will need replacement first, and when?

The internal lithium-ion cell is rated for about 28 hours per charge and will gradually lose capacity after several hundred cycles.

At what distance does the Bluetooth link usually drop during a long outdoor session?

The wireless range extends up to 100 ft, so the connection typically fails first when obstacles or interference push the effective distance beyond that mark.
