How many kilometers can a Tesla portable charger charge per hour?
3 Answers
Tesla portable charger can drive 50 kilometers per hour of charging through the 110V power supply that comes with the car. Here is the relevant introduction about the charging pile: Functions: The charging pile (plug) can achieve timed charging, electricity metering, and amount calculation, and can serve as a terminal for citizens to purchase electricity. At the same time, to improve the efficiency and practicality of public charging piles (plugs), functions such as multi-charging with one pile (plug) and charging for electric bicycles will be gradually added in the future. Technical implementation: As an energy supply device for electric vehicles, the charging performance of the electric vehicle charging pile is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are most concerned about before purchasing an electric vehicle. The basic principle of electric vehicle charger design is to achieve fast, efficient, safe, and reasonable power replenishment for power batteries. In addition, the applicability of the charger to various power batteries must also be considered.
I've been driving a Tesla Model 3 and using a portable charger for daily charging. Plugging into a standard household outlet (110V or 120V) only adds about 3 to 4 miles per hour, with a maximum of around 30 miles overnight. It's slow but convenient, perfect for topping up during home commutes. Switching to a 240V outlet, like in a garage or campground, can add over 20 miles per hour—much faster and really handy for trips. The best practice is to start charging when the battery drops to 20% and avoid frequent full charges to benefit battery longevity. I always keep this charger at home; just plug it in whenever needed without spending extra on fast-charging stations.
Charging speed depends on the type of outlet you use. I've tested different scenarios: a portable charger outputs 1.4-2kW at 110V, delivering 1-1.5kWh per hour, which translates to about 3-4 miles of range per hour. Switching to 240V increases the power to 7-10kW, charging 7kWh or more per hour, boosting the speed to over 20 miles, especially noticeable in models like the Model Y. When installing the appropriate outlet, check the current load to avoid exceeding 15A and prevent tripping. Actual charging also depends on the vehicle model and temperature, with slightly slower speeds in cold winter conditions. It's recommended to use 240V mode more often for higher efficiency, saving time and being more environmentally friendly, while also offering greater travel flexibility.
