3-5V DC 400W 15A ステップアップ LED ドライバー 充電器 電源 モジュール

This CA-888 power module works reliably with my LCD. The only small thing is that the wiring ports are a bit tight to plug in, but once connected, it runs smoothly.

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 CA-TB21 amplifier board is top-notch. The audio is clear, Bluetooth connection is stable, and it’s easy to wire up with 12V power. It transformed my old speakers completely.
