Portable 20 W Bluetooth 5.0 speaker

The NGS Roller Tempo is a battery-powered wireless speaker that delivers 20 W of audio output. It connects via Bluetooth 5.0 and supports True Wireless Stereo pairing with a second unit. A removable shoulder strap and a weight of 1 kg make it easy to carry outdoors.

Buyers wanting grab-and-go sound

This speaker suits listeners who want a single portable unit for music on the move and the option to add a second speaker for wider stereo. It is not for users who need mains-only operation, multi-room audio ecosystems, or built-in voice-assistant microphones.

20 W output and 5-hour runtime

The 20 W amplifier runs for up to 5 hours at 70 % volume from the 1500 mAh battery. That single figure decides whether the speaker lasts long enough for your typical outing.

Questions about this item

Does the speaker need a wall outlet, or does the built-in 1500 mAh battery let it run on its own?

The integrated 1500 mAh battery powers the speaker for up to 5 hours at 70 % volume, so no mains connection is required during use.

Can I link two of these speakers together for stereo sound using True Wireless Stereo?

Yes, the TWS feature lets you pair two units simultaneously over Bluetooth 5.0 to double the 20 W output.

How can I confirm the speaker is charging correctly after plugging it in?

Connect the micro USB charging port; the speaker's indicator will show charging status, and a full charge restores the 5-hour playback rating at 70 % volume.
