I used to make power bank and emergency lamp... working great as power bank...
werkt perfect en van goede kwaliteit
nice step up convertor for power bank diy project. I am going to use these one. genuine product.😊
They look good. I didn't test them yet but I assume they will work fine.
At 1v the output is 60mAmp at 5v. At 4V the current is 600mAmp.
Arrived on time, and in good condition, works as described.
Simply connect a voltage source between 0.9v-5v and it will work. A red led will be on when there's power
very good
las piezas llegaron bien protegidas y en buen estado
Ordered these for testing my TEG-peltiers and solar panels, great for low power use.
