Review: Great quality for little $$. Efficient! Be sure to use good speakers. - I have the DAMGOO ZK-502T and the ZK-1002 digital amps. They are both great running on a 16V laptop supply. Both provide plenty of volume. I have bought class-D for the TV and for the garage, and I got great results. I needed replacements due to a house fire. ** After a few weeks, mine failed. The BT "ready" signal continued to beep, interrupting music play on the wired input. BT has priority, and if it fails to connect, well, you are stuck with repeating beeps. desertcart Chat support quickly arranged for a warranty replacement with return of failed item. Replaced item works fine. ** The directions for these talk about what size of speakers they will support, and that small speakers require less power. This isn't right. The truth is that larger speakers are generally more efficient. In fact, if you have very large, efficient speakers, you can probably drive them straight out of your computer's sound card. I've done it. Your speakers will make all the difference; get good ones. If you go to a thrift store, only get a name brand like Sony, Aiwa, Yamaha, KLH, Pioneer. Never a lesser brand like Sharp or RCA. I have good quality 8 Ohm Yamaha speakers. If you use good quality speakers, you will not miss bass and treble controlls. Now I'll focus on the differences between these two that I think are most important. ZK-502T pro: bass and trebble controls! I like the flexibility. con: lame stick-on heat sink, probably should lay it flat. Better yet, mount with real thermal tape. ZK-1002 pro: larger screw-mounted heat sink, suitable for mounting in any position. Good, because mine is outside and exposed to the summer heat. pro: neat looking inductor coils, but I can't hear the difference. ZK-502T Current test with 2x 18650 cells (8 Volts) at 50% physical volume Average values: 50mA idle/quiet BT 100mA 50% vol BT 200mA 75% vol BT (with 1 Amp peaks) 600mA 80% vol BT (with 2 Amp peaks) 2500mA peak at 100% vol BT Recommended for long battery life: 2x 18650 cells with 2500mAh capacity, 12 to 24 hours runtime depending on volume. Better than some products off the shelf. Common A/C power supply recommendations: Minimum: 9V 1Amp Also suitable: 12V 3Amp, 16V 4Amp For 6dB greater distortion free volume: 19V 4.5 Amp Should probably not use less than a 12V supply with the 1002. The biggest difference between power supplies is that the audio is 6dB louder at most at 16V plus. The power regulator stays cool at 9V and begins to heat up at 16V. The main chip stays cool at 9V, and at 16V heat begins to build up as it is slowly dissipated through the board and components. I used a thermal camera to check this, and max temp I ever saw was a moderate 100 degrees F. Loud volume with a weak 9V supply can cause it to fail and restart. So only use a weak 9V supply if you plan on listening at moderate levels. With my 16V supply, there is sufficient current available for very loud music with no interruptions. Higher voltage is required for more volume, but results in more heat. At 16V, temps reach 115 degrees F. Semiconductors can take much more heat, and the main TPA311 chip has thermal protection. So these measurements are only for your information. The supplied stick-on heat sink didn't heat up much -- it is for show. Heat is also dissipated from the main chip through the board, however. I scraped off the black adhesive and used thermal tape instead -- with better results. I recommend you do this if you use a 24V supply. The reason I tested current usage was to confirm what I suspected -- that these amps are very efficient and require little power. I also wanted to know my battery life. I recommend 2 18650 cells. More than that will offer more volume, but will shorten battery life, as more power will be wasted in the power regulator. My AUX audio source is a Sony walkman mp3 player. Your source and/or a higher voltage power supply could get you more output power. But I believe it would never be close to 25 Watts, and this is something we should all be aware of. Bluetooth devices with Aux capability usually have better performance on BT. This amp is no exception. Idle power use is lower and audio is clearer at low levels. Current peaks at 2A before distortion sets in. Any supply with at least 2 Amps and a minimum of 9V should be good for a quiet location, 16V if a bit more volume is desired for a loud location. (edited) Good luck and have fun! -Chris
Review: Followed the advice in the reviews and it works great - I have it driving two 4” 30 watt rms car speakers, powered by a 12v, 3.5 amp wall wart I stole from an old router. Using car speakers both let me use coax 2-way speakers and get the most wattage out of the power supply. It works great. It can get very loud without distorting. It is super weird how it does NOT turn off when you think it’s off. If it’s plugged in, it’s on, and it will try to pair with something. So if you’re building a custom rig like I am, you’ll want to add an additional power switch.

## Features

- High-Quality Audio Performance: Featuring the advanced TPA3116D2 HIFI Chip with AM Interference Suppression, our ZK-1002 amplifier delivers outstanding sound quality. Even during extended high-power usage, it maintains a THD (Total Harmonic Distortion) of less than 0.1%, ensuring a superior listening experience.
- Versatile Voltage Compatibility: The ZK-1002 supports a wide input voltage range from DC 5V to 24V, allowing it to be powered by 9V, 12V, 15V, 18V, or 24V sources. This adaptability ensures that you can easily find a suitable power supply.
- Dual Audio Input Options: Enjoy the flexibility of two audio input methods. You can seamlessly connect through the latest Bluetooth 5.0 technology for wireless convenience, or opt for the traditional headphone (line-in) connection for your audio source.
- Comprehensive Protection: Our BT amplifier is meticulously designed to safeguard your investment. It incorporates multiple protective features, including over-voltage protection, under-voltage protection, over-heat protection, and short-circuit protection. Rest assured that your device is protected in various scenarios.
- Optimal Power Match: Please note that achieving the best audio output requires the right combination of sufficient audio input and appropriate power supply voltage and current. Different speaker impedances will affect the relative sound power. With adequate voltage and current, higher impedance speakers will produce lower relative sound power. Pay attention to these factors to optimize your audio experience.

## Questions & Answers

**Q: I plan to use this to drive piezoelectric tweeters at ultrasonic frequencies.  What is the upper range of this amplifier?**
A: The TI datasheet for the chip used in this amplifier shows about 28db of gain in a pretty flatline between 20 Hz to almost 40KHz.  By 100KHz you lose about 6db of gain.   So assuming their isn't additional RC filtering on your input signal.  All bets are off with Bluetooth though.  My guess is you are going to lose anything about the typically specified 20 - 20KHz using a bluetooth input just due to the ADC limitations.

**Q: Do you know what size of nut I need for the volume nob? I need a new one**
A: Bring the board to a hardware store and see if you can find one, but being such a big ID and small OD and super thin, you're going to be hard pressed to find one without ordering the specific potentiometer

**Q: can you custom name the bluetooth device?**
A: Yes on a iPhone you can! Go to blue tooth devices.... click the name you connected to ( when connected to the device) go to info and rename device.

**Q: Why am i getting a buzzung when there is no music? Very small audible hum**
A: I initially had a hum when I plugged into the headphone jack of my tv as well. I simply had to adjust the tv sound settings to Theater mode and the hum went away and the sound now works great!

### ⭐⭐⭐⭐⭐ Up to 3 of different styles!
*by C***R on October 17, 2025*

Bought a few versions of these; work great. Cuts out the static of the junk radio channel ones; cheap and easy to install. I just use a Milwaukee battery pack or wire it into the car harness.
