Airpods Pro news, charging issues?

[bubulol]

Hi i have bought new Airpods Pro and charged them with iPad 10w charger this afternoon
I came back and after 5 hours of continuously charging them, left earpiece only 53% and right earpiece about 78%, case is at 100%
Is that normal? I ordered from Amazon, its under blister, i dont think so its used Airpods Pro
Damnn why its chargeing so freaking slowly?
Why there are distinguish differences of battery from each earpiece?
Should i return them at Amazon?
Thanks

That’s not normal as each pod should charge up really quickly as the batteries are really tiny. Have you got optimise charging switched on as that can affect when the AirPods actually do charge. It may be that the charging points inside the case are faulty.
I don’t have a lot of confidence in Amazon as a lot of goods I have received from them have arrived in an atrocious state or faulty

Its under blister, its fully new but i think i managed to figure it out
I used lightning to usb-a from an iPad charger (10w), after some researches, Apple may drastically reduce the speed of charging through older lightning cable with usb-a
