In depth usage, yet to be tested!
Brand new, working circuit with good enough components has been delivered by this seller, although there was no brand packaging or else was available. Though this type of buck converter is a generic one, among various sellers. All in all allianzte alcoa prime can be trusted. Further updates regarding usage and application will be shared. This one is going to be used for converting 19v (from laptop charger) to 12v (11.1v) DC to be fed to the laptop through battery charging port. My laptop's power jack broke off from the motherboard, thats why i am trying to power the laptop through battery terminals directly.

Nice product.
This 300 watts buck converter is very helpful. I made a variable bench Power supply and it's still working flawlessly without any problem. But please improve your packaging. I used to order lots of products from Amazon but the packaging was always the drawback. Otherwise, I love Amazon.

worst product
i bought this product.first time defected product received.after replacement after one hour working its suddenly stop working. do not buy this product.it can be dangerous for sensitive equipments because when it stop working then it can not stepdown voltage.its starting give full voltage at output.input and output voltage becomes same. suppose you are charging 12v battery with 24v power supply and in the middle of charging it stops working and start giving 24v to the battery you can imagine what will be happen.

DC to DC step down working fine but as MPPT for solar panels are not working.
Voltage level decrease from input to output but current level can be same or decreasd w.r.t input. So as MPPT is not working. For step down DC to DC, it is ok.
