If it's a USB charger....frankly, I have more USB power supplies from various devices than I will ever use already. I do hang onto them, as every now and then I get a device that doesn't have serious power requirements that doesn't come with a power supply and can draw from USB. Have a digital carbon dioxide meter that can be powered by USB and didn't come with a USB power supply. A headphones amplifier that didn't come with a USB power supply and had audible noise spill into the audio when I tried plugging it into a powered hub running other devices -- power on USB is astonishingly dirty -- and that was solved by putting it on a dedicated USB power supply. But other than that, I tend to accumulate them faster than I use them.
Only time I get a charger is if I have a device that can draw more current than any of my existing unused chargers can put out (e.g. USB-C PD can now do something crazy, like 270 watts).
