Wireless Electric 3.7V Lithium Battery Megaphone Record Alarm

Lithium Battery Megaphone Description:

 

The alarm or siren feature typically produces a loud and attention-grabbing sound that is different from the regular voice projection of the megaphone speaker. Depending on the model, the alarm or siren can be activated by a button or switch on the device or through a remote control.

 

A lithium battery megaphone is a type of megaphone that uses a lithium-ion battery as its power source. Lithium-ion batteries are commonly used in electronic devices due to their high energy density, low self-discharge rate, and long cycle life.

Lithium battery megaphones are a popular choice for outdoor events, public speaking, and emergency situations, as they are portable and do not require a power outlet. They typically have a rechargeable battery that can provide several hours of continuous use on a single charge.
