What is a major trade-off when choosing between slow Level 1 chargers and ultra-fast DC fast chargers for electric vehicles?
Slow chargers are always better because they do not affect the energy grid at all.
Ultra-fast chargers are universally available and cost the same as slow chargers.
Fast chargers are more convenient but require expensive infrastructure upgrades, while slow chargers are cheaper but less practical for quick charging.
