Wuzhi ZK-502M Audio Mini 2.0 Stereo 50W+50W bluetooth Digital Amplifier Module 50W*2 AMP Amplificador Home Theater AUX USB
US$12.99 US$15.99

Q: Can the Wuzhi ZK-502M Audio Mini 2.0 stereo 50W 50W amplifier module be operated from a 19V 4.75A laptop adapter?

Maxweeber Sim. Vc pode utilizar até 24v e acima de 5A não tem problema . Eu utilizo uma fonte de 24v de 1.5 A e o som sai muito bom em auto falante de 15 polegadas Quanto mais alta a tensão, mais alta é a corrente e melhor é a potência de saída.

It finally arrived. It took almost 2 months to deliver, but I hope I didn’t wait in vain. This has been the slowest delivery so far. I couldn’t try it yet, the 120W dimmable power supply even disappeared from the supply over time. I'll be curious about your voice ...

Sounds good, just a little weak. It could be stronger, but it will turn out in use.

I already had my third order. The previous order was swallowed by the post office. I was immediately asked by three because the first was very good, but the third (at least two of the three) seemed to dry out. No flux flows from it, though I shake it as if there is some liquid in it. I haven't tried the rest yet, I hope that's all. I was satisfied with the first one, not so much ... It is a pity that the 3 products ordered at the same time are delivered separately, so one batch passes through Luxembourg, the other through the Netherlands, the third knows where it went, but in the end it's here.

Kisebb kitérővel, de magérkezett. Nem pontos méretű a nyák. Az érintkezők távolsága nem felel meg a kenyérlapnak, beerőszakoláskor feszül. A max. terhelhetősége épp csal elég, kicsivel lehetnen erőseb, de kellő odafigyeléssel a túlterhelés elkerülhető. Ha túláram/rövidzár védelem is volna, egész jól hasnálható lenne.

Megérkezett, elfogadható idő alatt. Kb erre volt szükségem SMD forrasztáshoz. Azért csak 4 csillagos,mert a logisztikán még javítani kéne. Egy megrendelés két tétele közül még csak egy jött meg, a másik még úton van. Az egyik luxemburgon keresztűl jön, a másik Hollandián keresztül. A logikát nem értem ez mitől jó és kinek.

Too bad it has only 00 rock code. With European reason (not just European, American) it would be better to order 02 with the code rom (HD44780UA02FS). If type 02 becomes available please email me. Thanks!

I haven't tried it yet, but it won't be easy to mount it on a test panel.

It has a bit of power consumption, and when powered by Pickit 4, the display slows down noticeably. Otherwise I'm satisfied though it could be cheaper.

GOOD! At least I was expecting something like that. It works from USB and external power supply (with 12V stabilization and noise suppression in my case), so far there is nothing wrong with what you need to know. The only problem is that the USB cable is very short (does not reach the desktop from the computer) but it works with another cable.
