    Modulo di potenza USB per batterie lipo, misure davvero contenute rispetto ad una moneta come da foto, necessario per i tuoi progetti, qualità ottima . Grazie Banggood

    It works ok, but it makes a fine pitched whine while working and the usb plug was poorly assembled it's very crooked..

    Fine for my needs. I got 70-80% efficiency with a charged LiPo (4.18v) and various loads. Should get more efficiency with higher voltage but this is what I'm going to use it with. My photo shows it converting 3.75v from an old LiPo to 5.30v.

    I used for charging cellphone from 3.7 V lithium ion battery. It's faster and reliable. It's good product.

    I bought this because I want to turn my nano quadcopter transmitter into a portable charger. It came in one piece and works right out of the package no problem! I set my power supply to 4V and tried it out using the charging cable I just got for my CX-10WD and it worked great. Would recommend to anyone.

    I bought this for use with fpv transmitter after removing the connector. It will be small weight step-up for small drones.

    Powerful power module to create a power bank charger with solar cells. Accepts 0.9 to 5V input and output there are about 5.1v to charge a power bank. Be aware that no input overcurrent protection is provided.
