A repeat of my input from previous questions on 120 V EVSE use:
Note that Nissan recommends the 120V EVSE for limited emergency use only.
Some people have used it for a long time without problems yet, but in general that is a bad idea unless you have a newly properly installed dedicated circuit with high grade receptacle using properly tightened screw connections.

Trickle charging should be safe, though, right? I wouldn't necessarily need to have the circuit certified for it or anything, should I? If I were to go to a friend's house, would I be safe plugging into their outlet?
How safe 120V charging is depends on how lucky you are.
Very few garages have the correct properly installed high quality single outlet supplied by a single breaker.
Code only allows using 80% of the circuit rating for a long term continuous load.
So on a 15 amp circuit nothing else should be on the same circuit while the car is charging.
And a lot of 120V gets put in poorly using push in connections.
One person had a bad fire most likely from staples that had damaged the cable in the wall.
