Features 1、Excellent ABS Material: This boost module is mainly made of excellent ABS material, which is sturdy and wear resistant, not easy to deform and high temperature resistant. 2、Lithium Battery Protection: This boost module has lithium battery protection, overshoot, overdischarge, over temperature, overcurrent protection, if the misoperation of the short circuit into the protection state does not output. 3、Small And Exquisite: This boost module has a small and exquisite appearance, and is very easy to install and replace. 4、UPS Function: When the power supply has power, the power supply directly from the power supply through the booster circuit to the load power supply, at the same time to charge the lithium battery. Once the power supply is disconnected, it will automatically start the battery path to supply power to the load through the boost circuit. 5、Wide Application: This boost module is used in a wide range of applications, machinery, electric power, telecommunication, communication, instrumentation, industrial measurement systems and so on. Specification Item Type: Boost Voltage Converter Material: ABS Charging Port: Micro USB Interface UPS Function: When the power supply has power directly from the power supply through the boost circuit to the load power supply, at the same time to the lithium battery charging. Once the power supply is disconnected, it will automatically start the battery path to supply power to the load through the boost circuit. Li Ion Battery Protection: Overshoot, Overdischarge, Overtemperature, Overcurrent Protection ( No output if short circuited by misoperation ) Package List 1 x Boost Voltage Converter Module 1 x Accessory
