Bottom line
The golden rule: a charger is for charging, not parking. Unplug and move when you're done, charge to about 80% at fast chargers, and you'll keep public charging pleasant for everyone.
As EVs go mainstream, public chargers are busier than ever. A few simple habits make the experience faster and fairer for everyone — and a couple of them can also save you real money.
The unwritten rules
- Don't treat a charger like a parking spot. Once you're done (or near 80%), unplug and move.
- Don't unplug someone else's car unless the session is clearly finished and you have no other option.
- Mind the time. Fast chargers are for topping up, not for filling to 100% — charging slows dramatically near full.
- Take your cable with you. If the site isn't cable-attached, leave the space tidy.
Get the most from fast charging
Charge to about 80%, not 100%. The final 20% takes disproportionately long, so on a road trip you're usually better off unplugging early and stopping again later. If your car supports it, precondition the battery as you approach the charger — it can meaningfully cut your stop time in cold weather. See how long charging takes for the details.
Charge cheaper
- Charge at home whenever possible — it's almost always cheapest.
- Use off-peak rates if your utility offers them.
- Compare network pricing — rates vary more than many drivers realize. Start with our charging cost guide.
Idle fees are real
Many networks now charge idle fees for leaving your car plugged in after it's full. Unplugging promptly isn't just polite — it saves you money.
The verdict
Public charging works best when everyone follows a few simple rules: charge, then move. Pair that with smart habits like the 80% rule and home charging, and EV life gets cheaper and smoother by the week.
