Our take on the Wireless Ultra Bluetooth Speaker with 66mm Drivers, 4000mAh Battery

This is a portable Bluetooth speaker built around two 66mm drivers, RGB lighting and an IP7 waterproof rating. It claims up to 40 hours of playtime from a 4000mAh battery and doubles as a power bank for your phone. Nominal output is 50W, rising to 80W when two units are paired in stereo. It suits people who want loud outdoor sound and long runtime more than a compact, hi-fi-grade speaker.

Questions and answers

Is it really waterproof?
It carries an IP7 rating, meaning it can survive immersion in shallow water for a short time. Most owners use it for splashes and rain rather than swimming.
How long does the battery last?
The claimed playtime is up to 40 hours, though real-world use at high volume with lights on will be shorter. The 4000mAh cell also charges a phone in a pinch.
Can I pair two speakers together?
Yes. Two units can be linked for stereo sound, which raises total output to a claimed 80W.
Does it have an aux or card slot?
It has a TF card slot for playing music from a memory card. Bluetooth 5.4 handles wireless playback.
Is it good for home use?
It works indoors, but its size and bass-forward tuning suit open spaces better. For a living room, a smaller speaker may be easier to place.
