Solar Charger USB C-C + rapid charge

[kentrain]

Does anyone know if a solar charger exists out there that supports USB C-C? I have this one from BlitzWolf but I'm wondering if there's a better one for the 6p out there : https://www.amazon.com/dp/B018QOYF6...ag=hawk-future-20&ascsubtag=UUacUvbUpU5467851
