Compact 40 W Bluetooth 5.0 Amplifier

The lelisten BT170 is a palm-sized digital amplifier delivering 40 watts of power for streaming audio via Bluetooth 5.0. It suits desktop speakers, small bookshelf pairs or DIY audio projects where space is limited. The extruded aluminum housing includes mounting tabs for secure installation in tight enclosures. A 12 VDC external supply is required but not included.

Upgrade from basic phone or laptop audio

This unit replaces the weak built-in amplifiers found in phones, tablets or laptops when driving passive speakers. The jump is worth it whenever you need louder, cleaner playback with adjustable bass and treble controls for a more lifelike balance. RCA inputs also allow wired sources such as a TV or media player. It is not for buyers who need multi-room streaming, subwoofer outputs or integrated power supply.

Limits of Bluetooth 5.0 and 12 VDC operation

Bluetooth 5.0 range and stability depend on walls, interference and the source device antenna. Audio quality is constrained by the codec negotiated between transmitter and receiver. The amplifier must be paired with a suitable 12 VDC power supply capable of delivering adequate current for 40 W output. No power supply, speaker wire or RCA cables are included in the package.
