All-in-one bedside speaker

The Gemini S300 combines a 16 W stereo portable speaker with a 15 W wireless charging pad and a 13-tone ambient light. Bluetooth 5.3, TF card and AUX inputs cover music, podcasts and white noise. A 3600 mAh battery runs the unit for 6-8 hours away from a socket.

Upgrade from phone speaker or basic charger

Replaces a standalone Bluetooth speaker plus a separate wireless charger and night light. The jump is worth it when you want one device on the nightstand that handles audio, fast phone charging and sleep-friendly lighting without extra cables.

16 W output for bedroom-scale listening

Dual 8 W drivers cover 27 Hz to 120 kHz for near-field music, movies and alarm tones. Battery life tops out at 8 hours at moderate volume. Wireless charging delivers 15 W only while the speaker is plugged into a 9 V/2 A adapter; on battery it reverts to standard speeds.
