What to know before buying

Listing details to confirm

Listing details are inconsistent: 20W appears in the title and feature text while the technical details state 24 Watts. The feature text claims a 5400mAh battery and up to 24 hours of playback, but the detailed battery specification only describes one included nonstandard battery. Confirm the exact power rating and battery configuration for the selected listing. The listed 10 Centimetres maximum range conflicts with a separate 10 Metres Bluetooth range, so the usable wireless range is unconfirmed. The IP68 rating and immersion conditions are feature-text claims, while the technical details only say Waterproof.

Frequently asked questions

Does the JUOVI J6311 support wired and offline playback?

The listing names Bluetooth, TF card and AUX connections. Its feature text says a TF card can play audio without a phone, and the box list claims a 3.5 mm line-in cable is included.

How powerful is this speaker?

The listing is inconsistent. Its title and feature text state 20W, while the technical details give a maximum output of 24 Watts. Confirm the rating for the selected listing.

How long does the battery last?

The feature text claims up to 24 hours of continuous play from a 5400mAh battery. This is a maximum listing claim, not a guaranteed runtime for every volume or use condition.

Can it be used near water?

The feature text claims an IP68 rating and says it can withstand immersion up to 1.5 metres for up to 30 minutes. The technical details only list it as waterproof, so verify the protection level and conditions before relying on immersion protection.
