Thanks for this awesome review 😁 I bought a suspiciously similar power supply from Amazon a few weeks ago. Different branding, but otherwise identical. The beeping was driving me nuts too, and I'd overlooked that part of the manual, so many thanks for pointing out that it can be disabled 🎉 I'll have to see what the ripple current is on the USB for mine. If it's as bad as yours, then I'll try your capacitor solution too.
@@SnapTinker tested it just now, and there's definitely a ripple on mine too. If I'm reading my oscilloscope correctly, it's between 100mA and 200mA. So about the same as yours, it would seem.
Is it possible to set the voltage to 30 volts and the amps to 3 amps and maintain it until I’m done using it? Every time I try it lowers my voltage on me
If you set cc-limit at 3 amps, voltage drops at 3 amp load. That is how cc/cv works. Below cc limit voltage should not drop ( except measured at cable ends because of cable resistance). If cc limit is above 3 amps, your device is faulty or this device does not function well at max values. I cannot test myself, I don't have proper test load.
I have not had any problems with it. It delivers 10A as expected, but I did not have a long time load test though. The only issue is the ripple current of usb-port. Can I fix it with a capacitor? Some day I'll test that.

That is freaking cute ps ❤

It would be interesting to know if high ripple voltage at USB port is a common problem. So, if you can comment after measuring your unit.

This is recomended or not to buy, cause the price in Indonesia is lowest than psu by sugon with 30V 5A, this waptek price around 80$ and sugon 100&
Hello!Please tell me, how did the power supply unit perform?Thanks!

I soldered a 100uF capacitor into usb output. It solved the ripple voltage problem. Easy fix!
@@SnapTinkerCan you show how?
I have another video on my SnapTinker channel, where I do ripple voltage fix, adding a capacitor.
