G5_BLK 25W Bluetooth 5.3 speaker

The GravaStar G5_BLK is a portable Bluetooth speaker that also functions as a lamp. It delivers 25W of total power through a 3-inch mid-low driver and a 0.5-inch high-frequency tweeter. The frequency response spans 20 to 20k Hz with a signal-to-noise ratio of 90db. Bluetooth 5.3 and AUX inputs provide wireless and wired connectivity options.

Indoor listeners wanting light and sound

This unit suits users who want a single device for audio playback and ambient lighting in a home or campsite setting. The zinc-alloy body and integrated handle support portable use. Buyers who need longer battery life for multi-day trips without charging access should look at other options. The speaker is not designed for professional monitoring or critical listening environments.

9-hour playtime at 60% volume

Battery life is rated at around 9 hours when played at 60% volume, with a 3350mAh capacity and 3-hour recharge via Type-C. Standby time reaches 18 months. This single figure determines whether the speaker fits your daily usage cycle between charges. Actual runtime will vary with volume level and lighting mode selection.

Questions about this item

What comes in the box with the GravaStar G5 Supernova speaker and is anything else needed to start using it?

The package includes the speaker, a 1 metre USB-C charging cable, and a handle for carrying; no extra accessories are required to begin playback via Bluetooth 5.3 or the AUX input.

Should I choose this 25W model or is there a higher-powered version listed?

The G5 Supernova is offered in this single 25W configuration with a 3350mAh battery delivering around 9 hours at 60% volume, so no alternative power tier appears in the lineup.

How loud and clear will the 25W output actually sound in a typical room?

The dual-driver design pairs a 3-inch full-range unit with a 0.5-inch tweeter to cover 20-20k Hz at 90dB SNR, producing room-filling bass and detailed highs from the 25W amplifier.
