Portable RGB Bluetooth Speaker, 5W Stereo, 800mAh, BT 6.0
Product Overview
A pocket-sized speaker that fits 5 W of stereo sound into a 135 x 53 x 85 mm body. Bluetooth 6.0 pairs quickly and holds a stable 10 m connection, while the 52 mm driver, passive radiator and twin diaphragms give bass that is unusual at this size. The RGB ring on the end cap cycles through colour as it plays, and the splash-resistant fabric mesh keeps it safe on a campsite table or a kitchen counter. Buyers can also play straight from a USB drive or TF card, tune FM radio, or plug in an AUX cable - no phone required.

Frequently Asked Questions
What are the playback options?
Five: Bluetooth 6.0, a USB flash drive, a TF/SD card up to 128 GB, FM radio, and AUX line-in for wired sources. The speaker works without a phone or app.
How loud is the 5W output?
Peak output is 5 W through a 52 mm 4 ohm driver, assisted by a passive bass radiator and two diaphragms. Frequency response is 20 Hz - 20 kHz with signal-to-noise ratio of at least 75 dB, so bass holds up at moderate volume without distorting.
Is it waterproof?
The front is covered by a high-density splash-resistant fabric mesh over a rugged chassis, which handles rain spray and splashes at a campsite or poolside table. We do not quote an IP rating for this model; tell us your target market and we will confirm the exact test level required.
How long does the 800mAh battery last?
Runtime depends on volume and whether the RGB light is on. We do not publish a single figure because it varies by use; ask for a test report and we will provide measured runtime at your target volume.
