- The – Raspberry Pi 3 A+ is power efficient, but not very powerful and was tested by Explaining Computers, as well as other Raspberry Pis.
- all Raspberry Pi boards require a 5 volts power supply
- We tested before a Raspberry Pi4 with Ubuntu Mate with a power bank we bought on Aliexpress for 20 USD which has 10 000 mAh capacity.
- Running time idling was about 4 hours
- Explaining computers did a similar tests as we did and reached a battery life of 15 hrs with a 10 000 mAh power bank.
- The Raspberry Pi 3A+ had a battery life of 27.7 hrs in the same setup tested by explaining computers.
Tests with Lead Acid powered batteries
battery used:
Yuasa NP7 12FR 12v 7.0 Ah
- charging time was 12 hours
- additionally we need a Power buck converter 12 V to 5 V 5 A to convert the 12 volts to 5 volts for Raspberry Pis
running times tested by Explaining computers with lead acid battery
- 40 hours with led acid battery for Raspberry Pi 4
- 72 hours with the Raspberry Pi 3 A+
