Connectivity options are versatile, including support for MicroSD cards, USB flash drives, and AUX input for playing music or connecting to other devices. However, it is worth noting that the microphone and speaker need to be kept at a distance from each other to avoid signal interference.

The device is made from durable ABS material, which is wear-resistant, but users should handle it with care to prevent damage. With a customer rating of 4.4 out of 5 stars from over 3,500 reviews, it is a well-regarded product in its category. This voice amplifier is a reliable and flexible tool for anyone needing to project their voice in various settings.

The SHIDU 35W Power Voice Amplifier is designed specifically with teachers and presenters in mind, offering strong sound output that can cover large rooms or classrooms with up to 320 people. Its 35-watt power output ensures clear voice projection, which is a key factor in crowded or noisy environments. One of its standout features is the wireless 2.4G lavalier microphone that offers stable, noise-free connection with up to 40 meters (131 feet) of wireless range, allowing freedom of movement without worrying about tangled wires.

Battery life is impressive, with a built-in 3100mAh rechargeable battery lasting up to 16.5 hours on a single charge, suitable for long teaching sessions or events without frequent recharging.

Some considerations include the need to position the microphone and speaker carefully to avoid feedback or strange noises, which may require some adjustment. Additionally, while it supports Bluetooth 5.3 for music, the voice transmission relies on a separate 2.4G connection, which might be confusing for some users. This amplifier is ideal for teachers, trainers, and speakers who need reliable voice amplification with good battery life, portability, and clear audio in medium to large spaces. It might require initial setup to avoid feedback but delivers great value with solid power and wireless features.
