It has been purchased for several weeks now and serves as a power supply for a diesel heater. Apart from the start-ups that draw around 10+ Amps, it operates at 2-3 amps during continuous operation. So far, it works quite well. I opened it up (I am knowledgeable in electronics), it has a simple circuit, plenty of space for heat management, Chinese semiconductors - okay - a monolithic power supply. The output voltage can be adjusted from 11.5-13, which is very useful for a variety of applications. It's worth the money. I would not recommend someone to buy it for power-intensive requirements.

Purchased on 22/2/2021, it worked fine for 2 weeks and suddenly stopped. After checking that the LED strip was not the issue, I looked at the power supply and discovered that the warranty sticker was already cut, which means someone had opened it and possibly repaired it before reselling it as new

Purchased in early 11/20. Very powerful power supply, revived the LED strips I have in the kitchen cabinets that I considered finished. The voltage is adjustable, it gives a maximum of around 14.8 (measured with a multimeter).
If it withstands time, it will be an excellent product.

The power supply continues like the first day. No difference, no problem !!!!!!!
