CA-502L MINI 5.0 เครื่องกระตุ้นพลังงานเสียงดิจิตอลไร้สาย 50Wx2 bt เครื่องกระตุ้นเสียง

I’ve been using this Creatall AS21 amplifier for my home theater setup for a month, and it’s been fantastic! The build quality is top-notch—metal construction feels durable and premium. The TPA3255 chip delivers crisp highs, balanced mids, and deep, punchy bass that fills the room without distortion. Bluetooth 5.1 pairs quickly with my phone and smart TV, and the connection stays solid even through walls. I appreciate the multiple input options (AUX/USB/Bluetooth) that let me switch between devices easily. The protection features (overheat, short circuit) give me peace of mind for long-term use. The company’s customer service was responsive when I had questions about wiring, and the sample delivery was fast (arrived in 7 days as promised). For the price, it’s way better than some expensive brands I’ve tried—highly recommend for anyone looking for a reliable, high-performance amplifier!

The voltage regulator works reliably for my LED TV. The heat sink is a bit smaller than I thought it might be, but it hasn’t overheated during regular use.

This BMS board functions well for my battery—it provides good protection. The manual is only in English, which I had to translate, but it’s easy to use once I understood the specs.
