I've had more problems with chargers last few years. I have an antique charger that an old woman gave me in 70's that still works. Been through a bunch from Wally world and last one was a Schemake I bought online. I really thought it was great till it stopped working in a few months. About ready to call or return it for service. Checked it over and found cheap wire was broken on clamps. Repaired the connection and it's again charging.
