Why is My Tesla Only Charging at 16 AMPS
Charging your Tesla at a slower rate can be frustrating, especially if you’re used to charging at higher speeds. There are several reasons why your Tesla may only be charging at 16 amps, said by EV charger manufacturers, which is a lower rate compared to the typical 40-50 amps that most Tesla models are capable of. Some potential reasons for slower charging include using a lower amperage charging outlet, an older or less powerful ev charging cable, or the presence of other electrical devices on the same circuit that are drawing power. It’s also possible that there is an issue with the charging system itself, such as a fault in the charging port or a problem with the vehicle’s onboard charging electronics. This post will explore why your Tesla may be charging slowly and the Amps available by Tesla or other Top EV charger companies.
I. How Many Amps is a Tesla Charger?
The amount of amps that a Tesla charger can deliver depends on the specific model of the vehicle and the type of EV charger being used. Tesla vehicles are equipped with an onboard charger capable of accepting a range of charging currents, depending on the available power supply and the vehicle’s charging system. Likewise, to not compensate for your car seat covers comfort, you can install leather seat covers for unmatched aesthetics, which are easy to clean, and provide a comfortable surface
when it’s cold.
Most Tesla models come with an onboard charger capable of accepting up to 40-50 amps of current. This allows the vehicle to charge relatively quickly, depending on the available power supply and the charging infrastructure. For example, a Tesla Model 3 with a 50-amp onboard charger can charge at a rate of up to 72 miles of range per hour when connected to a 240-volt Level 2 charging station.
In addition to the onboard charger, Tesla also offers a range of home and public charging solutions designed to work with its vehicles. These chargers are available in different amperes and voltages, depending on the needs of the customer and the available power supply.
For example, the Tesla Wall Charger is a Level 2 charger designed for home or business use. It is available in 40-amp and 80-amp versions, which can deliver charging speeds of up to 72 miles of range per hour for a Model 3. The Tesla Wall Charger can be installed with a range of power supply options, depending on the needs of the customer and the availability of a suitable electrical circuit.

Similarly, Tesla’s Supercharger network is a network of fast-charging stations designed for long-distance trips. These chargers are available in different amperes and voltages, depending on the specific location and the needs of the vehicles being charged. For example, the Supercharger V3 is a fast-charging station capable of delivering up to 250 kW of power to compatible vehicles, allowing them to charge at a rate of up to 1,000 miles of range per hour.
II. Why is Tesla Only Charging at 16 AMPS?
There are several potential reasons why your Tesla may only be charging at 16 amps, which is a slower rate compared to the typical 40-50 amps that most Tesla models are capable of. Some common causes of slow charging include:
- Use of a lower amperage charging outlet: If you’re charging your Tesla at a wall outlet or other low-power charging source, the available amperage may be limited. In this case, the vehicle may only be able to charge at a slower rate.
- Use of an older or less powerful charging cable: The charging cable you use to connect your Tesla to the charging source can also affect the charging speed. If the cable is damaged, frayed, or otherwise not functioning properly, it may not be able to deliver the full current to the vehicle.
- Presence of other electrical devices on the same circuit: If you have multiple electrical devices drawing power from the same circuit as the charging outlet, it can reduce the available power and cause the charging rate to slow.
- Fault in the charging port or onboard charging electronics: There may be an issue with the charging system itself, such as a problem with the charging port or a fault in the vehicle’s onboard charging electronics. In this case, the vehicle may not be able to accept the full available current.

My Tesla charged at 32 amps until the end of July but now only accepts 16 amps .I went to the Tesla service centre and even new cars amps panel will not go above 16 amps.Tesla say this is usual for home chargers but my charger has worked well for three years-what is going on as the situation affects the time for charging at a cheaper rate and also affects the battery life if I constantly charge above the recommended 80%
I would welcome any feedback-I have had the charger checked and it’s ok
I have found that as a Universal Mobile Charger (UMC) ages that it will start becoming problematic. Initially charging at 32A and become unreliable and dropping to 16A during a night charge.
I have monitored the input voltage at blue 32A connector, which is 232V UK and on the old UMC the car reports fluctuate from 220V up to 227V with a normal mid reading of 225V.
I have replaced the UMC with a new charger and the car reports a stable 230V without fluctuation delivering 32A without a problem.
My conclusion is that the performance of the relay in the UMC diminishes with age or regular used delivering 32A.
This is my second UMC replacement. The 16/32A issues was resolved previously by replacing the charger with a new one.
As they are relatively cheap I’m seeing this as an acceptable ongoing cost as apposed to installing a wall mounted charger.
I do not have the answer for you I’m afraid Marv. I suggest you contact the car manufacturer for an explanation. All the best.
I am using the charging station and cable that came with the car. It is connected to a 40A breaker. It always starts charging at 32A and after 5 or 10 minutes drops to 16A. I can restart the charging to get back to 32A but it only lasts for 5 or 10 minutes.
