What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: the title claims 40W while the details list 30 Watt-hours, which measures energy rather than power, and the connection field says USB despite separate Bluetooth 5.0 claims. The 2,1 channel configuration also differs from the 2.2 CH description. The listed weight of 44 Grams and dimensions may warrant confirmation. Treat the stated power, channel arrangement and physical measurements as unconfirmed and check the selected listing before purchase. Battery runtime is claimed at 50% volume and varies with volume and audio content.

Customer feedback highlights favourable impressions of sound, compact size and flashing lights, with some considering the speaker good value. Battery life and reliability receive mixed reports, including reports of very short unplugged operation and units stopping work. This matters if you intend to use the claimed 8000mAh battery for long outings. The listing's runtime claim is up to 10 hours at 50% volume, but customer feedback does not establish that every unit will achieve it.
