Sorry for such a newbie question. I am still trying to find my feet. I know that a battery cannot be charge and discharge at the same time as I find this:
No, a battery can't be charged and discharged at the same time. If a battery is connected to a charger delivering 1 A and a load drawing 3 A, then the battery will be discharged at 2 A. There is no simultaneous charging and discharging going on
But I have just purchased this:
RAVPower Portable Charger 20000mAh 60W PD 3.0 USB C Power Bank 2-Port Power Delivery Battery Pack High-Capacity External Battery
Does that make a difference? Can I charge and discharge at the same time? I forgot to order the PD plug so I cannot actually test that at the moment.
Any guidance even just to tell I am stupid? :)
NB To add more info. This is my User Case:
I have an enclosure with a raspberry pi. It is connected to a usb power bank. I have an external port where I can plug the usb power bank to an external charger. At the moment when the battery runs down I charge it by connecting a power source to this charger. I also turn the Pi off via SSH command. It charges OK. I was only wondering if I could avoid that step of using software to turn device off. So, scenario is:
- Raspberry Pi is running and powered by usb power bank
- The usb power bank runs out of charge
- The raspberry then powers off
- I plug an external power supply to recharge this usb power bank
- As soon as it does the raspberry pi starts up again.
So i am now in the situation that the Raspberry pi is running and the usb power bank is charging at the same time.
I figured it MAY be able to work because you recharge a phone this can also be the same scenario?
