5v 1a Ups Uninterrupted Module 3.7v Mer 18650 Reverse Ity Pro

Input mode: IN+ input positive, IN- input negative, Output mode: OUT+ output positive, OUT- output negative, Battery: B+ is connected to the positive pole of the battery, B- is connected to the negative pole of the battery, Indicator light (you need to it yourself): R+ is the working state of the external power supply, G+ is the battery capacity indicator, and the battery capacity is displayed by the frequency of flashing. The faster the flashing, the more the battery capacity is, and it will automatically turn off when it is not loaded or not . Jumper (J1) description: used to set the power of the external power supply, the default is to short the jumper, the external power supply current needs to be 1A; when the external power supply current is less than 1A, the jumper needs to be disconnected and switched to 0.5A current for power supply , the load is preferentially supplied, and the remaining current is transferred to the battery for charging. parameter: Input: Above 5V1A Output: 5V1A (max) Battery: polymer lithium battery, 18650 lithium battery. (recommended capacity 10000ma) Input: The external power supply voltage should be less than 6V. Battery side: reverse connection protection, short circuit protection, reverse connection will not be damaged during charging. Output: It can only supply common loads, and cannot be connected to other power adapters, and it will burn if connected in reverse, and the output is short-circuited, and it will not sleep when the load is small. Size: 33 x 15 x 4.5mm Material: PCB Color: green Package Contents: 1 x Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
