Portable Bluetooth 5.0 speaker for outdoor

The SUPNIU A21 is a 2.1 channel portable speaker built around dual woofers and dual tweeters. It delivers 60 W RMS output with an 80 W peak rating and uses Bluetooth 5.0 for wireless streaming up to 100 ft. A built-in 8000 mAh battery provides roughly 6 to 10 hours of playback depending on volume.

Sustained output and battery management

At moderate listening levels the 60 W continuous rating can be maintained throughout the quoted battery window. Higher volumes draw more current and will reduce the 10 hour upper estimate toward the 6 hour lower figure. The frequency response spans 27 Hz to 120 kHz so bass extension remains audible during longer sessions.

Build, connectors and everyday mounting

The cabinet measures 2.4 in by 3.96 in by 1.3 in and finishes in black. A 3.5 mm AUX input, TF and SD card slots, USB flash drive port and FM tuner give multiple wired and offline sources. An included infrared remote handles playback, EQ, karaoke mic level and the LED light toggle without reaching for the speaker.

Questions about this item

How hot does the 60W speaker get and how much power does it draw when playing all day?

The unit runs on an 8000mAh battery that lasts about 6-10 hours depending on volume. It charges via DC 5V input and has no fan, so heat stays low during typical use.

What cables or devices do I need to start using the Bluetooth 5.0 speaker right away?

The box includes the speaker and a remote control that needs two AAA batteries. A 3.5mm AUX cable and a USB power adapter for the DC 5V input are not included.

Will the 2.1 CH system with dual woofers work with my older MP3 player that only has a headphone jack?

Yes. The 3.5mm AUX input lets you connect any device with a headphone output, and Bluetooth 5.0 pairs with older phones or tablets that support it.
