Wireless microphone does not need to charge, he takes battery power, each replacement of a new battery, to ensure the normal power supply at the scene, charging batteries will cause unpredictable risks on the scene, such as battery damage, battery supply shortage, charger failure, etc., the use of dry batteries can discharge such problems, although increased consumption, but the safety factor is higher
There are generally two kinds of wireless microphone batteries commonly used now, one is to use a 9V battery, that is, the square. Another way is to use a pair of 5 batteries. Both of these batteries are rechargeable, and if the wireless microphone uses this rechargeable battery, it can be recharged.
