Usually yes, level 1 is plugging into a typical 110V socket. You can also adjust the amperage draw on some chargers. I can go from 6 to 12 A in 2 A increments on the one that came with my ioniq 5.

Level 2 is 220V and 25-80 A (<20kW).

Level 3 is technically anything above 20 kW, but usually 50 kW is the floor. These are the EV-specific fast chargers or Tesla’s Superchargers.

An EV on level 1 (or 2) is a continuous load, so I’d imagine probably easier to handle than an intermittent load.
