Li-ion Battery Charger Boost Module 3.7V Step Up 9V 5V 2A Adjustable Board 100% brand new and high quality Features: Made of high quality material, solid, durable and strong conductivity. Before debugging, the default output is about 9V. The input voltage is 4.5-8V. The output voltage can be continuously adjusted to 4.3-27V(Over 4.3V or more, below 27V or less, any voltage can be output, and you can adjust the voltage counterclockwise). Wide range that charging voltage 4.2V Charging current is 1A, while output reference maximum current 5V 1.4A , 9V 0.8A, 12V 0.6A. It can be said that there is 2V cut-off boost, but there is still 2V without blocking the output. The cut-off boost 2V, , whether add a protection board or not depends on the situation. For example: VIN+Port input 5V solar panels, BAT+port can output 4.2V to charger 3.7V 18650 battery Specification: Material: Integrated Circuit Board Size: 3.3 x 2.3 x 0.9cm/1.30 x 0.91 x 0.35in Color: As picture shown Quantity: 1 Pc Product Parameters: Input Voltage: 4.5-8V Output Voltage: 9V Output Reference Maximum Current: 5V 1.4A , 9V 0.8A, 12V 0.6A Static Current: 0.5 mA Note: No retail package.
