The product
Images published by the manufacturer, used for review with credit. Each one links back to where it came from.
What the box will not tell you
Recharging the battery takes roughly 5 hours, and the speaker lacks any official dust resistance rating despite its IPX7 waterproof build.
I would think twice
Outdoor users in dusty or sandy environments, or those needing fast charging turnaround — The speaker lacks an official dust resistance rating and requires approximately 5 hours to fully recharge.
A recommendation, not a ruling. You know your own use better than I do.
