Solar powered bank or solar powdered charger for iPadAir 4th gen and iPhone 13 Pro.??

I would like to purchase a solar powered bank or solar powdered charger to take on a trip to Kenya. I have an iPad Air 4th gen with WIFI & cellular and iPhone 13 pro. I know that the iPhone is wireless charging but the iPad is not so what kind of solar powered charger or bank would work for both devices. Or do I need two types of solar chargers? I will be where there is no electricity. Thanks.
