- A detachable strap is listed in the package contents, and the speaker can also be placed on a tabletop or freestanding.
- Power-bank functionality can provide 10W charging to a phone or other essentials.
- Custom EQ gives buyers a way to adjust the sound through the app.

What to know before buying
Listing details to confirm
The listing's technical details conflict: they state a 10-meter Bluetooth range and also a separate 100-meter maximum range, and specify a 12000 milliamp_hours capacity while also listing one included C battery. Confirm the intended battery and range specifications before relying on them. Its package list names a USB-C to C cable but does not specify a 30W charger, which the three-hour charging claim requires.
