How Fast Will My EV Charge at a Campground?

The Bottom Line

If you are at a campground with a 50-amp hookup (NEMA 14-50), you are going to charge at roughly 25 to 35 miles of range per hour. Plug in after dinner, wake up to a full battery. That is the best-case scenario, and the one you should plan around whenever possible.

A 30-amp hookup (TT-30) is a different story. It runs on 120 volts, so you are looking at about 8 to 11 miles per hour. That said, we do not recommend TT-30 adapters due to safety concerns with auto-resetting charge rates after power interruptions. See our outlet guide for the full explanation.

A standard household outlet? About 3 to 5 miles per hour. That is trickle charging. It works if you have two nights and nowhere to be, but it is not a real strategy.

Charging Speed by Hookup Type

Here is what you can realistically expect from each outlet type at an RV park. These numbers assume your EVSE draws at 80% of the circuit rating (the safe continuous limit) and your vehicle's onboard charger can handle the load.

What Affects Your Actual Charging Speed

Those numbers above are estimates. Your real-world speed depends on several factors that can push the number up or down.

• Your vehicle's onboard charger capacity. A Tesla Model 3 Standard Range has a 7.7 kW onboard charger, which maxes out at about 30 miles per hour even on a 50-amp outlet. A Model S with the 11.5 kW charger can go faster if the outlet supports it.
• Your EVSE's amp limit. The Tesla Mobile Connector caps at 32A. Some aftermarket chargers go to 40A or even 48A.
• Temperature. Cold weather slows charging because the battery management system has to warm the pack first. A freezing night in Colorado will charge slower than a warm evening in Arizona.
• Battery state of charge. Charging slows down as you approach 100%, just like DC fast charging. You will see the fastest speeds between 10% and 80%.
• Campground electrical quality. Old wiring, long runs from the transformer, or shared circuits can reduce the voltage at the pedestal. If you are seeing 220V instead of 240V at the outlet, your charging speed drops proportionally.

Real-World Speeds by Vehicle

Every EV charges a little differently because of onboard charger capacity and efficiency. Here is what owners are actually reporting at campgrounds.

Planning Your Overnight Charge

The math is straightforward. Figure out how many miles of range you need by morning, check what hookup type the park offers, and do the multiplication.

Say you arrive at a campground in Utah with 40% battery on your Model Y Long Range (about 120 miles of range remaining). Your next stop is 200 miles away, so you need at least 200 miles total by morning, ideally 250 to have a buffer. That means adding about 130 miles overnight.

On a 50-amp hookup at 30 miles per hour, that takes about 4.5 hours. Plug in at 8 PM, you are done before midnight. Easy.

On a TT-30 at 9 miles per hour, that same 130 miles takes about 14.5 hours. Plug in at 6 PM, you are not done until 8:30 AM. Tight, but doable if you are not in a rush.

On a standard 120V outlet at 4 miles per hour? That is 32.5 hours. Not happening in a single night. You would need to plan a two-night stay or find a DC fast charger nearby.

Practical Tips for Faster Campground Charging

• Book 50-amp sites. They are the only hookup type we recommend for EV charging. They often cost $5 to $10 more per night than 30-amp sites, but the speed and safety differences are substantial.
• Plug in as soon as you arrive. Do not wait until bedtime. Every extra hour on the charger counts, and starting early means you can charge at a lower, gentler amp rate and still wake up full.
• Set a lower charge limit if you do not need 100%. Charging to 80% is faster because the car does not need to slow down for the last 20%.
• Check the park's EV policy before you book. Some parks include electricity, some meter it separately. A park that charges by the kWh might cost you $5 to $15 for an overnight charge, which is still cheaper than most public chargers.
• Know where the nearest DC fast charger is. If the campground cannot give you enough range overnight, a quick 20-minute stop at a fast charger on the way out can top you off. Our park directory shows nearby DC fast charging locations for every listing.
