Super Slow L1 Charging?

Better than a voltmeter, get a $2 circuit tester at the Depot (the one with 3 LED lights) and see if they wired the outlet wrong.

If you have a voltmeter, I'd check voltage before and after charging starts. If you're getting a big drop, I'd stop using the outlet.

Two different issues, both tests are useful.
