What is a Portable EV Charger?
Portable EV chargers are a smart solution developed to address a common concern among electric vehicle (EV) owners — range anxiety. Even though modern EVs, including many affordable models, can now travel over 250 miles on a single charge, some drivers still worry about running out of power before reaching a charging station.
In simple terms, a portable EV charger works much like a power bank you use for smartphones, tablets, or wireless headphones. Just as a power bank provides extra charge to your devices when you’re away from a socket, a portable EV charger offers a temporary energy boost to your vehicle. However, unlike a home or public charging station, it usually does not fully recharge an EV’s battery. Instead, it supplies enough electricity to help you reach the nearest proper charging point safely.
| Feature | Details |
|---|---|
| Purpose | To reduce range anxiety by offering a backup energy source for EVs. |
| Functionality | Similar to a portable power bank, it provides temporary charging support. |
| Capacity | Enough to get the EV to a nearby charging station; not intended for full battery recharges. |
| Use Case | Ideal for emergencies or when charging stations are out of reach. |
Important Points to Consider Before Buying a Portable EV Charger
Portable EV chargers typically provide only enough power for about 20 miles of driving. This is usually sufficient to reach the nearest public charging station, but not enough to replace your regular home or public chargers. Therefore, it’s not recommended to depend on them for everyday charging needs due to their limited range.
You can think of a portable EV charger as an emergency backup for your electric vehicle.
During long trips, especially through areas with fewer public charging stations, a portable charger can offer peace of mind. If your EV runs out of battery unexpectedly, a portable charger can help you get moving again without needing to call for roadside assistance.
However, with careful planning, you may never even need to use a portable charger. To prepare for a long journey, it’s wise to:
- Identify all compatible charging stations along your route.
- List backup charging options at each stop in case your first choice is unavailable.
- Allow extra travel time in case you have to wait to use a charger.
Exploring the world of portable EV chargers reveals some important insights that every electric vehicle owner should know. Here’s a quick breakdown:
- Widespread Access: Today, portable EV chargers are readily available across many countries, making it convenient for EV drivers to find the right device.
- Energy Efficiency: Compared to traditional gas-powered generators, portable EV chargers are typically more efficient in their energy use.
- Charging Speeds: A Level 1 portable charger may take up to 20 hours to fully charge a vehicle, whereas a DC fast charger can accomplish the same in less than an hour.
- Built-in Safety Features: Modern portable chargers are equipped with safety technologies such as automatic shutoff and overheat protection.
- Pricing: The cost of portable EV chargers usually falls between £150.00 and £1,200.00, depending on their features and charging capabilities.
- Eco-Friendly Options: Solar-powered portable chargers are emerging as an increasingly popular green alternative.

Types of Portable EV Chargers
In the past, several portable EV chargers were introduced for personal use. However, currently, there are no portable EV chargers available for individual consumers in the UK market.
Earlier models mainly provided AC charging with power outputs up to 9.6kW — similar to a regular home charging unit — and were small enough to carry in a car’s boot. However, their charging capability was limited, typically offering a range boost of only 20 to 40 miles.
On the other hand, there are some commercial portable EV chargers available for purchase. These chargers use DC fast charging technology and can deliver power up to 20kW.
Unlike the personal-use models, these chargers are bulkier because they are made up of multiple battery units, forming a large power pack.
Depending on the model, commercial portable chargers can add around 70 miles of driving range. Due to their size, they cannot be carried in standard EVs like hatchbacks or SUVs — instead, they must be transported separately, usually in a service van, for roadside charging assistance.

How Do Portable EV Charging Stations Work?
When you use a portable EV charger, there’s much more happening than simply plugging it in. Here’s a breakdown of how these devices function:
1. Power Conversion: Portable EV chargers draw alternating current (AC) from a standard power source, like a home outlet. However, EV batteries require direct current (DC).
-
The conversion from AC to DC is usually handled by the onboard charger inside the vehicle itself.
2. Connector Types: The connector you use depends on your car model and the charger type:
- Level 1 and Level 2 chargers typically use a J1772 connector (common for most electric cars).
- DC fast chargers often use either a CHAdeMO or a CCS connector for faster energy transfer.
3. Smart Features: Many portable chargers come with advanced features such as:
- Mobile apps for remote monitoring and charging control.
- Scheduled charging to optimize energy use and cost savings.
- Automatic adjustment of charging speed based on factors like the battery’s temperature and the available power supply.
4. Safety and Efficiency: The charger and your EV work together to ensure safe, efficient charging, preventing overcharging or overheating by intelligently managing the power flow.
