GravaStar Supernova 25 W Bluetooth speaker

The GravaStar Supernova is a portable Bluetooth speaker that delivers 25 W of amplified stereo sound. Professional acoustic algorithms aim to keep audio clear even at maximum volume. A detachable handle makes it easy to carry the 4.4 kg unit to parties, outdoor gatherings or camping trips. Eight RGB colours across three lighting modes add a visual element to playback.

Check Bluetooth source and TWS needs

Verify that your phone, tablet or laptop supports Bluetooth audio streaming before ordering. The speaker offers True Wireless Stereo pairing so two units can be linked for wider soundstage. Battery life reaches up to 28 hours per charge, so plan charging intervals for longer events. Wireless range extends to 100 ft in open conditions.

Thermals noise and power in normal use

The 25 W amplifier runs cool enough for tabletop or lap use during typical listening sessions. No active cooling fan is present, so operation stays silent apart from the audio output. Power draw scales with volume level and lighting mode, staying modest at moderate settings. The 28-hour battery rating reflects real-world mixed usage at default brightness.

Questions about this item

Does the Supernova black come with a charging cable or do I need to buy one separately?

The speaker ships with a USB-C charging cable in the box so you can power the 28-hour battery without an extra purchase.

Should I pick the 25-watt Normal Version or is there a higher-output model listed?

Only the 25-watt Normal Version appears in the data, so that is the single option available.

How far can I actually roam with the 100 ft wireless range claim once the speaker is paired?

The 100 ft figure is the quoted maximum line-of-sight range; walls and interference will reduce the practical distance.
