QC3.0/QC2.0 USB DC-DC Buck Converter Module - 6-32V Input lipoly this is what they characterizeUSB buck converter that turns a 6 32V input into a fast charge USB output. Defaults to 5V, then negotiates up to 12V once a fast charge handshake kicks in. Speaks the common fast charge protocols: QC2. 0, QC3. 0, BC1. 2, MTK PE, Apple, Samsung AFC, Huawei FCP, Spreadtrum SFCP. Good for car chargers, battery packs, and solar fed charging. Specs Input 6 32V DC Output 5V default, 3 12V on fast charge Max power 24W (5V 3. 4A, 9V 2. 5A, 12V 2A) Efficiency
