Ask HN: One Charger for All Devices?

Is there a charger I can use across devices that can give the required power based on the devices and not harm the device? Would be great if it has multiple ports. I have an iphone se, Samsung note 9, kindle, Samsung Bluetooth Wireless headphones.

I did see the Anker - https://www.amazon.com/Anker-PowerPort-Charger-Charge-PowerIQ/dp/B01N2HIR9R/. Just want to know if their claims are true. Anyone that understands the technical side of charging?
