Hi yes it will charge from any quality usb charger although not as fast, mine charges happily from my old Samsung charger, Hope this helps. No it's charge with any type c chargers cable I think you are correct, I've tried it with an S10 charger and noticed it's wasn't rapid charging like normal Yes seems ok charging from any usb port as long as has usb c connection on lead to connect to phone. Yes just a bit slower as the Google charger has quick charge. I am using the charger that came with the phone don't know if it works with any other charger. Any charger####[['fast', 'Battery/Longevity#Charging Speed', 'negative'], ['charge', 'Battery/Longevity#Charging Speed', 'positive'], ['charging', 'Battery/Longevity#Charging Speed', 'negative'], ['slower', 'Battery/Longevity#Charging Speed', 'negative']]
