Integrated storage and charging

The Pyle M04 is a 20 W portable voice amplifier with a built-in cradle that stores and recharges the wireless lavalier microphone after each use. It targets teachers, tour guides and presenters who need a self-contained PA system that keeps the microphone powered and ready without separate chargers or cables. The all-in-one design reduces the risk of lost or dead microphones during daily speaking engagements.

Upgrade from wired or standalone megaphones

This unit replaces handheld megaphones or wired microphone setups that tether the speaker to the amplifier. The jump is worthwhile when you need hands-free mobility and automatic mic charging between sessions, eliminating the hassle of disposable batteries or misplaced transmitters. It is not suited for users who require multiple simultaneous wireless microphones or coverage beyond small-to-medium rooms.

12-hour battery and 20 W output

A 2600 mAh rechargeable battery delivers up to 12 hours of continuous use after a 1.5-hour charge, covering a full teaching day or event on a single cycle. The 20 W stereo output projects clear, natural voice reproduction across classrooms and small venues, while the 0.02 lb magnetic lavalier mic stays comfortable for extended wear. Battery life and output will fall short for large auditoriums or multi-day events without recharging.

Questions about this item

How do I charge the wireless lavalier microphone and what is the common mistake?
