Frequently Asked Questions

What is a 1kW charging rate?

A 1kW charging rate means your Tesla is receiving 1 kilowatt of power per hour while charging. This is a relatively slow charging speed compared to faster options like Tesla Superchargers or home chargers with higher amperage. A 1kW charge will add a limited amount of range to your Tesla per hour.

How does a 1kW charger work?

A 1kW charger utilizes a standard 120-volt outlet (like the ones used for household appliances). The charger converts this alternating current (AC) to direct current (DC), which your Tesla battery can use. The power output is limited to 1 kilowatt, resulting in the slower charging speed.

Why should I consider using a 1kW charger?

While slow, 1kW chargers are convenient for topping off your Tesla’s battery overnight or while at work. They are also the most accessible option, as most locations have standard 120-volt outlets. This makes them ideal for occasional charging or for situations where faster chargers aren’t available.

How do I start using a 1kW charger with my Tesla?

Simply plug your Tesla’s Mobile Connector into a standard 120-volt outlet. Your Tesla will automatically detect the charging rate and begin charging. You can monitor the charging progress on your car’s touchscreen.

What if my Tesla is only charging at 1kW even though I have a faster charger available?

This could be due to a few reasons: 1) Your Tesla might be set to a lower charging limit. Check your car’s settings to see if you’ve manually restricted the charging rate. 2) The faster charger might have a fault. Try restarting the charger or contacting the charger provider for assistance. 3) Your car’s battery might be nearing full capacity. Charging slows down as the battery approaches 100%.

Which is better, a 1kW charger or a faster charger like a Supercharger?

It depends on your needs. 1kW chargers are great for occasional charging or topping off your battery, but they are slow. Superchargers are much faster and ideal for long-distance trips or when you need to charge quickly. Consider your charging frequency and the amount of time you have available when making your decision.

How much does it cost to charge my Tesla at 1kW?

The cost of charging your Tesla at 1kW depends on your electricity rate. You can estimate the cost by calculating the kilowatt-hours (kWh) used and multiplying it by your electricity rate. For example, if your electricity rate is $0.15 per kWh and you charge for 5 hours, the cost would be $0.75 (5 kWh x $0.15/kWh).
