Everything You Need to Know About Tesla Charging: Amps, Wall Connectors, and Future-Proofing Your Setup


Understanding Tesla Charging
When it comes to charging a Tesla, there are a lot of different factors to consider. One common question that people have is whether or not the Model 3 standard range PLUS can charge at 48 amps. The answer is no – this model only supports a maximum of 32 amps when using an on-board charger.
It's important to note that the actual "charger" is part of the vehicle itself, while the device used to connect the car to a power source is called an Electric Vehicle Supply Equipment (EVSE) or charging station. A Gen 3 Wall Connector is recommended for daily charging as it has a built-in GFCI and eliminates the need for plugging in and out over time, which can cause sparks.
However, if you're looking to save money and don't mind plugging and unplugging your car every day, you can use the mobile connector kit with a NEMA 6-50 outlet. Just be aware that this setup will only yield a maximum of 32 amps, even if sized correctly with a 60 amp breaker and 4 gauge copper wire.

Future-Proofing Your Charging Setup
If you plan on upgrading to a different Tesla model in the future, it may be worth investing in a Gen 3 Wall Connector now to future-proof your charging setup. This device supports up to 48 amps and can accommodate upcoming models that require higher amperage.
It's also worth noting that some Tesla models come with different battery types that affect their charging capabilities. For example, the Model 3RWD range plus has an LFP battery that limits its rate of charge to 30 amps. However, newer models like the Cybertruck may support up to 80 amps with a gen 4 wall connector.
Ultimately, it's up to you to decide what works best for your budget and needs. If you're on a fixed income but still want peace of mind with a warranty, it may be worth considering slightly used models from recent years instead of brand new ones.

DIY Installation and Other Considerations
If you're handy with electrical work and have a qualified electrician friend, you can install your own EVSE without going through Tesla's list of approved electricians. Just make sure to follow all safety precautions and check local building codes before beginning any installation.
Another consideration when choosing a charging setup is portability. While the mobile connector kit offers convenience for travel, it may not be ideal for everyday home charging due to wear and tear on outlets over time. Additionally, purchasing separate adapters like the 6-50 adapter can add extra costs.
In conclusion, understanding how Tesla charging works can help you make informed decisions about your charging setup. Whether you opt for a Gen 3 Wall Connector or stick with the mobile connector kit, remember to prioritize safety and future-proofing when making your choice.
