Powerbank endurance test for Raspberry Pi 3. | testing how long a raspberry pi can be powered via a powerpank

Iv like to test and know how much uptime can be achieved by different powerbank.

I purchased this powerbank case on ebay and then purchased the 18650 3.7v batteries separately.

I have built two powerbank with identical cases but different batteries. 

  • Powerbank – $5.35
  • Batteries 18650 9600mha – $24.80
  • Batteries 18650 6000mha – $22.49

The results?

  • Batteries 18650 9600mha – 23 Hours
  • Batteries 18650 6000mha – 18 Hours

It should also be noted that the Raspberry Pi is online via wifi during the whole test while getting pinged every minute.
