Do not use Fast Chargers on the old Devices. Fast Chargers can go to 9V and 12V which damage older devices that are meant for only 5V. Use only the charger supplied by the device maker when possible.
Also new Power banks that have Fast Charging may damage old 5 V Devices. Use a Legacy 5V 2A power bank for older devices.

When the smell of Ionized Air and Burnt plastic reaches your Nose; you need to check the Mains Plugs and Sockets of all heavy Electrical Appliances for Sparking.
Replace even if slightly tarnished. It is more so in 15A plugs and sockets driving Heaters or Motors.
