Get not only 5 volts but also 9, 12 volts (18 Watts max) out of any QC-compatible charger/power bank for supplying power hungry projects.
Every engineer needs at least one bench power supply in his house. I agree one can get the power supply directly from the store. How else?
I hacked to DPS3005 power supply, by connecting a TI CC2640R2F LaunchPad using UART interface to add Bluetooth connectivity!
