What this speaker is

The GravaStar Mars Pro is a portable Bluetooth speaker built with a zinc alloy metal body. It delivers stereo sound through a dual speaker system and includes six RGB lights. The speaker weighs 4.4 kg and is intended for home, outdoor, party and camping use. It is sold new in black.

The spec that decides fit

This model uses BLUETOOTH 5.0 for wireless connectivity and offers 15 hours of playtime on a charge. It supports stereo pairing so two units can be linked from a single source device. Volume is adjusted through an LED touch control on the speaker itself.

Heat noise and power in use

The speaker runs on its internal battery for up to 15 hours with no external power required during playback. There are no moving cooling parts so operation is silent aside from the audio output. The zinc alloy chassis passively dissipates any warmth generated by the amplifier.
