Question about Ugreen Charger

If a solar cell is installed for charging at the same time as the load, does the voltage remain stable even if the solar cell sometimes supplies more and sometimes less power? I need a constant 5V and approx. 900mA for 24-hour operation of a Rasoberry with Birdnet software.

The voltage is stable, the battery in the power bank has around 3.7V, so it must always be increased for the 5V USB. Therefore, it does not matter if the battery voltage drops to 3.0V or rises to 4.2V during charging. The solar cell for charging the power bank would then also always supply at least 5V (USB standard). Please note that you can operate the Raspberry on the power bank for a maximum of 20 hours without a solar cell. This means that two consecutive cloudy days will very quickly come to an end.

I'm sorry, but I can't answer this question. Do not use a solar cell
