How often does your phone chargers need to be replaced?
How often does your phone chargers need to be replaced?
Um, never?
I've lost chargers on several occasions, and I've switched from older ones to newer ones for faster charging, but the older ones still work as spares.
Cables, on the other hand....
Unless you have a USB mini connector -- which you probably don't, if it's just a two-year-old device -- you could potentially have just replaced the cord.
The USB mini connector went away specifically because with that plug, the device had the tensioning bit that wore out and got sensitive to being wiggled, rather than the cable. USB micro and USB C should have it on the (cheaper, more-readily-replaceable) cable.
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).
