UPS for Raspberry PI 4B/3B+/3B

Ep 0014 3.jpg


This is a new version of UPS Board.It not only supports Raspberry Pi 4B but also adds type C output. It provides enough power for the Raspberry Pi to make your Raspberry Pi still work while moving, and its design is so smart that you can get rid of troubled of a mass wire. This UPS can provide you with the operation of replacing the battery yourself. It can use most of the 18650 standard batteries and fully comply with the battery characteristics in terms of battery life. In addition, the power display provided on the circuit board is also very user-friendly. The illuminated LED light can quickly show the remain power and support the discharging while charging. You can directly connect to the external power supply for charging. At the same time, the Raspberry Pi will not be turned off.
Please install the battery first, then connect the UPS to the Raspberry Pi.
Connecting too many high-power peripherals will lead to insufficient power supply. Please pay attention to the power demand of peripherals.



Please do not reverse the battery! Only for 18650 batteries and the discharge rate should be less than 10A !!!

This product belongs to the power supply device. 
Please keep it out of the reach of children. Please strictly refer to the instructions for the UPS  product. If the battery polarity is reversed, it will directly burn the power management chip of the device and even cause fire or personal injury. Do not add any Components by yourself, all accidental damage caused by the cause is at your own risk.

Make sure your power adapter capacity can cover lithium battery charging and raspberry pi use case, typically is 5V 3A or better should be used.

(ex:Battery charge may require up to 2.1A, Raspberry Pi typically requires 0.6-0.8A, but up to 2.4A, at which if the power supply current is less than 4.5A, it may not be able to continue use)

Customer Review

 NOTE: Thanks for Mat Zolnierczyk's Review


  • Q: Why i press the button,the UPS Board works for seconds then turn off?
 A: May it feels hungry,I think it should be charged.
  • Q: What happens if I use a battery that is not of good quality?
 A: The battery may explode.We recommend you using a high quality battery.
  • Q: It will be hot when using the battery. Is this normal?
 A: Not only when it is used, it will heat up when it is charged,but the temperature couldn't too high.Temperature cannot exceed 60 degrees Celsius.
  • Q: What is the maximum charging power? What is the maximum discharge performance?
 A: Charging up to 2.1A, rated discharge power is 15W
