2019-01-10Excellent!!!
2019-02-09This is a mediocre product. I tested its boost capability from 3.0V here are the results I measured with my bench power supply and an USB meter:* Vin 3.0V, Ipsu=2.1A, Vout=4.88V Iout=1.0A* Vin 3.0V, Ipsu=3.1A, Vout=4.80V Iout=1.47A* Vin 3.3V, Ipsu=3.1A, Vout=4.77V Iout=1.65AIt is visible that it is far from 5.0V, Vout drop quickly even above 1.0A load. It can withstand 3.0A for a couple of minutes (I did not test it longer), but with such a voltage drop, it is only hardly better than the Mt3608 based boards, but this is really expensive at this price level (2.5USD). If it was below 1USD, I'd call it as a good purchase,
