Most home circuits are rated for 15-20 amps, and stacking several high-wattage chargers on one strip can approach that limit faster than people expect.
Planning around realistic constraints — panel capacity, available outlets, or shared infrastructure — usually matters more than any single piece of hardware.
Practical starting point
Map out actual daily charging needs (what, how often, how much time available) before buying hardware, rather than buying for a worst-case scenario that rarely happens.
