The idea of using a portable EV charger on a daily basis is an intriguing one, especially as electric vehicles (EVs) become more integrated into our everyday lives. As the transition to electric mobility accelerates, many EV owners are exploring the flexibility and convenience that portable EV chargers might offer. However, the feasibility of this approach hinges on several critical factors, including charging speed, home charging infrastructure, vehicle compatibility, and the practicalities of everyday use.
1. Charging Speed and Range
Charging speed is a primary consideration when assessing the viability of a portable EV charger for daily use. Portable chargers, which are typically classified as Level 1 EVSE, operate at a slower rate compared to the more robust Level 2 EV chargers commonly found at public charging stations or installed at home. Level 1 chargers typically deliver around 1.4 to 2.4 kW of power, which translates to adding approximately 3 to 5 miles of range per hour of charging. This rate might be adequate for short daily commutes or for drivers who do not require a significant range each day. However, for those with longer commutes or higher daily mileage, relying solely on a portable EV charger could mean spending several hours or even overnight to fully recharge the vehicle.
In contrast, a Level 2 EV charger, whether installed as a home EV charger or accessed at a public charging station, offers a much faster charging speed, typically delivering 7.2 to 11 kW of power. This allows for a more substantial range—about 20 to 30 miles per hour of charging—making it far more practical for daily use, especially for drivers who cover considerable distances. The slower charging speed of a portable EVSE might be a limiting factor, particularly if the vehicle’s battery capacity is large or if the driver’s routine involves frequent or extended trips.
2. Home Charging Infrastructure:
Another essential aspect to consider is the availability of a suitable charging infrastructure at home. For a portable EV charger to be used effectively on a daily basis, access to an appropriate electrical outlet is necessary. Typically, a 240V outlet is required to optimize charging performance, as standard 120V outlets will only further slow down the charging process. Many homes may not have a readily available 240V outlet in a convenient location for charging, which could necessitate additional electrical work to install a dedicated circuit. Moreover, safety considerations should not be overlooked—ensuring that the outlet and any extension cords used are rated for the charger’s power to avoid electrical hazards is crucial.
3. Charging Location
The location of where charging will take place is another key factor in determining the practicality of using a portable EV charger daily. Charging at home, especially overnight, is the most convenient option, allowing the vehicle to be ready for use each morning. If the driver’s workplace also offers accessible outlets, this could extend the viability of a portable EVSE by providing an additional opportunity to charge during the day. However, if public locations are necessary for charging, the process could become more cumbersome. Public spaces are not always equipped with accessible outlets, and even when they are, finding a suitable spot, dealing with time constraints, and the potential inconvenience of setting up and monitoring the charge can be significant drawbacks.
4. Vehicle and Charger Compatibility
Vehicle and charger compatibility is another consideration that cannot be ignored. Different EV models may require different connectors, such as J1772, Type 2, or CCS, and it is essential to ensure that the portable EVSE is compatible with the specific vehicle. Furthermore, the power rating of the charger must align with the vehicle’s charging requirements. Mismatches in compatibility or insufficient power ratings could lead to inefficient charging or, in some cases, might not work at all.
5. Portability and Convenience:
Beyond these technical aspects, the practicalities of daily use come into play. Portable EV chargers, by their very nature, are designed to be moved and used in various locations. However, this portability often comes with trade-offs. These chargers can be somewhat bulky and heavy, which might make them less convenient to carry around regularly. The length of the charging cable is another practical consideration; it needs to be long enough to reach the vehicle’s charging port from wherever the outlet is located, which might not always be straightforward depending on the parking situation at home or work.
Given these factors, the overall feasibility of using a portable EV charger daily depends heavily on individual circumstances. For some, especially those with short daily commutes and consistent access to suitable charging outlets at home and work, a portable EVSE could serve as a viable and flexible solution. In such cases, the slower charging speed might be offset by the convenience of charging the vehicle overnight or during work hours, ensuring that the vehicle is sufficiently charged for the next day’s activities.
However, for others with more demanding driving patterns or less predictable schedules, relying solely on a portable EV charger might not be as practical. The extended charging times, potential lack of access to appropriate outlets in public locations, and the inconvenience of transporting and setting up the charger regularly could outweigh the benefits of portability. In these scenarios, a more permanent solution, such as installing a Level 2 EVSE home charger, might be more suitable.
Advantages of Portable EVSE for Daily Use
A home EV charger, particularly a Level 2 charger, offers several advantages over a portable EVSE for daily use. The higher charging speed means that the vehicle can be fully charged in just a few hours, making it more convenient for drivers with longer commutes or those who need their vehicle ready at a moment’s notice. Additionally, a home EV charger is typically more reliable and requires less manual intervention once installed. There’s no need to worry about finding a suitable outlet, carrying the charger around, or dealing with potentially awkward setups in public places.
Furthermore, the installation of a home EV charger can be tailored to the specific electrical infrastructure of the home, ensuring that the setup is safe and efficient. While the initial investment in a home EV charger and the associated installation costs can be higher, the long-term benefits in terms of convenience, reliability, and charging efficiency often make it a worthwhile investment for regular EV users.
Nevertheless, the decision between relying on a portable EV charger versus a more permanent home EVSE installation ultimately comes down to individual needs and circumstances. For some, the flexibility of a portable EVSE, despite its limitations, might be exactly what they need. For others, the stability and efficiency of a home EV charger, especially a Level 2 charger, will likely prove to be the better option.
Value the Portable EV Charging and Home EV Charging as per Your Needs
Thus, while it is technically feasible to use a portable EV charger on a daily basis, it is not without its challenges. The slower charging speeds, the need for suitable outlets, and the practicalities of transporting and using the charger regularly can all limit its practicality for everyday use. However, in the right circumstances, particularly for those with shorter commutes and consistent access to charging facilities at home or work, a portable EVSE can provide a flexible and effective charging solution.
On the other hand, for those with more demanding driving requirements or who value the convenience of faster charging times, investing in a Level 2 home EVCS is likely to be a more practical and satisfying solution. By carefully considering your specific needs, driving habits, and the available charging infrastructure, you can make an informed decision that best supports your journey into electric vehicle ownership. Whether you opt for the flexibility of a portable charger or the stability of a home EV charger, ensuring that your vehicle is always ready to go will allow you to fully embrace the benefits of electric mobility.
