I like the product. I use it to power raspberry pi’s off of lipos. What would really help make this a great product for powering a raspberry pi, is if I could change a component resistor, diode to bring the output voltage up to 5.25 – 5.40v. I used the Micro LED DC-DC Digital Boost Voltage Converter LM2577 and was testing turning up the voltage to see when the raspberry pi low power icon would go off. that was about 5.30 v. After thinking about it for a while, I realized the pi has a 5v voltage regulator, so it really needs more than 5.0 volts which is what most usb power bricks provide. Thanks in advance.
