Mini Stereo Amplifier for Desktop Audio

The lelisten Mini Bluetooth Amplifier is a compact 2.0-channel stereo amp that delivers 20 watts per channel into 4-ohm speakers and 10 watts per channel into 8-ohm speakers. It ships with a 12 V 5 A DC power adapter and fits in one hand, making it suited for near-field listening on a desk, bookshelf or small living-room setup. Buyers who need more than two channels or higher continuous power for larger rooms should look elsewhere.

Replaces Integrated Device Audio

This unit upgrades the limited headphone jack or built-in speaker amplifier found in phones, tablets, laptops and older MP3 players by adding AUX, USB and Bluetooth inputs with a dedicated volume knob. The USB connection supports lossless playback when linked to a computer, while Bluetooth adds wireless convenience for streaming services. The jump is worth it when the source device lacks clean line-level output or sufficient drive for passive bookshelf speakers.

Sustained Output with Protection Circuitry

Under continuous playback the amplifier relies on its 12 V 5 A supply and built-in short-circuit, over-current and thermal protection to maintain stable operation without shutting down. The multifunction knob allows input switching and playback control without reaching for the source device during long sessions. Remote control is included for volume and track changes from the listening position.

Questions about this item

What size speakers and what impedance does the 20 W × 2 amp need?

The amplifier delivers 20 W per channel into 4-ohm speakers and 10 W per channel into 8-ohm speakers; it is powered by the included 12 V 5 A DC adapter.

How do I switch between Bluetooth, AUX and USB inputs using the multifunction knob?

Press the knob repeatedly — each press cycles through the input modes; the same knob also handles track changes, app activation and factory reset depending on press count.

Which protection circuits will shut the unit down if a speaker wire shorts?

Built-in short-circuit and over-current protection automatically cut power when a fault is detected, preventing damage to the amplifier and connected speakers.
