Voice Amplifier for Teachers and Outdoors

This 18W portable voice amplifier includes a wired headset microphone designed for teachers, tour guides and coaches who need clear projection across groups of 20 to 65 people. The compact black and green unit weighs very little and clips to a waistband for hands-free use during lessons or outdoor activities. It is a new, all-in-one system built for voice reinforcement in open or noisy environments.

Bluetooth Speaker and Power Bank Functions

The device streams music from phones or tablets via Bluetooth and accepts non-Bluetooth sources through an AUX input while the microphone remains active. It also plays audio from TF cards and USB drives and can record, though cards and drives are not supplied. A built-in 4400mAh battery lets the amplifier serve as an emergency power bank for charging a phone when away from mains power.

12-Hour Battery and IPX5 Water Resistance

A full charge in 3 to 5 hours delivers up to 12 hours of playtime, covering a full teaching day or extended outdoor session. The IPX5 rating protects the speaker against splashes and light rain during outdoor use, but the microphone is not waterproof and the unit must not be submerged. Sound coverage reaches 10000 sq.ft, which suits large classrooms or open spaces.
