Hi guys ! we use power banks to charge mobile devices when we are away from home or when there is a power cut. Also, a power bank can be used as a power backup system even for security cameras that operate with 5v. So, in this video, today we will talk about a power bank module that can be used to make a DIY power bank at low cost and how to make a power bank using the module.
---Parameter---
Input voltage range: 5 ~ 5.5V
Charging cut-off voltage: 4.2v/4.35v
Charging current: 2.4a
Boost output voltage: 5V ~ 5.15v line loss compensation
Boost output voltage ripple: 100mV
Boost output current: 2A
Boost conversion efficiency: 92.5% 3.6V input, 5v2a output
Battery static current: 30uA
---Function---
* When the load current is less than 50mA continuously, the output will be turned off.
* Support external key,
* When the charging current drops to 100mA the charging cycle will be automatically terminated.
* When the battery voltage drops below 4. 1V, the charging cycle starts again.
* When the battery voltage is lower than 2.8V, the battery will be pre charged at 180mA.
* It supports discharging while charging.
