## Customer Reviews

### ⭐⭐⭐⭐⭐ Hard Punching Lightweight
*by R***F on July 21, 2025*

Well worth it. Very clean sound. No noise. Plenty of power. HINT: those 20v batteries on your power drill are perfect for creating a portable boom box project.Years before Bluetooth speakers became a thing (but after iPods) I cannibalized Klipsh, Cerwin Vega, Altec, JBL, home speakers to build boom boxes and have recently replaced the old amplifiers with these. They ALWAYS work fine. And your battery will play for hours if you are reasonable with the volume. Most folks don’t realize how much volume you can get with 1 watt/channel, 15 is overkill.Still, watch out for distortion and high end sizzle because it’s possible to overpower some high efficiency speakers.

### ⭐⭐⭐⭐⭐ Perfect for my project needs
*by F***E on May 27, 2025*

It works as intended, no noticeable issues with audio quailty. Bluetooth connection is good and it gets much louder than you might expect from a little amp that sits in the palm of your hand. Perfect for a little project.

### ⭐⭐⭐⭐⭐ Small, cheap and powerful sound amplifier DIY. My very old speakers look new and amazing again
*by A***L on June 26, 2021*

First, I enjoyed the simple pleasure to build it. I like very much listening music. My wife asked me for years that I throw away my old aiwa and jbl speakers. I builded it in less than 10 minutes with the included small screwdriver. Instructions are available in youtube. I had to get an ac/dc adapter (12 V, 1 A). It was an amazing moment for me when I attached my usb flash with music, and when I connected my smartphone with bluetooth. I ordered additional units to make gifts to friends.
