Review on π 10Pcs Boost Step Up 5V 1A Power Supply Module with Lithium Battery Charge Protection Board 134N3P - DIY Charger with USB and Micro USB Port, LED Display by William Chavez
Doesn't produce 5v on battery
Judging by the reviews I had high hopes for this unit. Of the five I tested, none were able to boost the battery voltage from 3.7V to 5V. The battery was fully charged and the output was 4.1V on battery power. The output went to 5V when connected to a 5V power supply. They don't work as advertised.
- Great for a small house
- Some bugs
