Instructions For Portable EV Chargers


Portable EV charger is an EV charging device that can be carried with the vehicle and used in any environment with power supply conditions. Some products will be equipped with different EV adaptors, which can adapt to different power sockets, which is very convenient. Because it can be carried with a car, its volume is smaller and lighter than a wallbox. The output power is generally 3.5kW. The output power of some high-power versions of portable EV chargers can reach 7kW, up to 16kW. The length of the effective charging cable is generally 5-6m, and it can reach 8-9m for special customization service. But generally, it will not exceed 10m.

A portable EV charger appeared later than a wallbox charger. In view of its charging power and product functions, the market volume of portable EV chargers in some regions is not as large as wallbox chargers. The main reasons are as follows:

  • Requires longer charging time
  • Functions are not as powerful as an EV wallbox charger, for example, it’s unable to export charging data
  • Ordinary electric vehicle users prefer to use EV wallboxes at home
  • Portable EV charger generally does not support app or ocpp functions and cannot be controlled remotely
  • The portable car charger regular model does not support the remote upgrade of the background program

However, the market growth rate and market potential of portable EV chargers are very huge. It has two great advantages that can make up for all its shortcomings: simple operation and cheap price. With the popularity of electric vehicles and the continuous updating and iteration of portable EV charging products, portable EV charger is being recognized and accepted by more and more consumers. No car owner will refuse to put a cool-looking partner in the car who can charge anytime, anywhere. Moreover, with the change of people’s concept, the main role of portable EV charger is from charging EVs to replenishing EV power at any time. Now, the use habit of a wallbox charger and a portable EV charger in a family is developing.

Europe3.5kW (single phase) / 16kW (three phase)IEC62196-2
China, India and some South Asian markets3.5kWGB

The different market has different market demands, relevant standards, design directions and certification requirements. So before deciding to customize portable car chargers, we must first determine where our target market is. 

Positioning Of Portable EV Charger

It is very important to clarify your product positioning before starting a customized project. It’s directly decided

  • Product design ideas for the portable electric vehicle charger
  • Function selection of portable electric vehicle charger
  • Selling points of products of the portable electric vehicle charger
  • Components selection for the portable electric vehicle charger
  • Materials Selection for the portable electric vehicle charger
  • Cost budget for the portable electric vehicle charger

It is unrealistic for a product to cover all customer groups. As long as its product positioning and corresponding market demand are clear, both simple and high-end models can have their own corresponding markets and appropriate customer groups.

Selling Points Of Control Box

Any good and impressive product will have its core values. Selling points must be attractive and easy to promote. If a product claims to have all the selling points during publicity, then it has no special recognition for customers. From the perspective of marketing, a product full of selling points has actually no selling points. Therefore, it is very important to determine the selling points before product design. This can not only effectively improve the recognition of their own products, but also determine a clear marketing direction before sales. Generally speaking, the selling points of the portable EV charger can be considered in the following directions:

  • Stable and safe performance of portable EV charger
  • Charger durable and anti-pressure
  • With an intelligent adapter, suitable for various scenarios
    Intelligent chip, automatic error correction
  • Strong adaptability, and high compatibility with all EV models
  • Intelligent program upgrade

A product can have many advantages, but as a selling point of marketing, it’s best to lock the one that stands out and is easiest to remember. More importantly, determining the selling points can make our design more targeted.

Distribution Channel Of Portable EV Charger

A complete and effective sales strategy is crucial to the sales of products

  • Is it offline store mode or online sales mode?
  • Is it sold on self-built stations or on Amazon
  • Have your own sales team or as an importer who wholesales to other distributors?

To be exact, there is not much correlation between the sales channel and the customization of the control box. The sales channel mentioned here is just an example.

We expect every customer to think carefully when ordering portable EV chargers, and give comprehensive consideration to every detail. It’s like a battle. Before the battle begins, careful preparations need to be made.

We will also provide suggestions in some key places based on our experience. Every customer can get benefits through cooperation with us and avoid detours, which is what we want to see.

Things To Consider Before Customize Portable EV Charger

Compared with the customization process of EV wallbox chargers, the customization of portable EV charger will be relatively simple, with fewer parameters to be determined, and the related costs will be cheaper. This is why we recommend new customers choose the customized project of portable EV chargers first.

Equipment structure:

Considering that the portable EV charger is sometimes placed on the ground, it is inevitable to encounter vehicle rolling, so we generally do not recommend customers make too complex structures. Basically, the main structural direction is anti-pressure with a solid shell.

Device function:

A portable EV charger is mainly used as a supplement to the way of charging outdoors. Its main function is to be suitable for normal use in different charging environments. We will pay more attention to the identification and adaptation of different charging environments, and it is not recommended to add too many complex functions to a portable EV charger. Of course, if there are special requirements or customization is needed in order to follow the high-end route, we can also add the required functional modules according to the requirements.


A portable EV charger needs to face the same waterproof problem as an EV wallbox in outdoor use, the possibility of being soaked by rain is even higher since it is placed on the ground. Therefore, compared with the EV wallbox, it also has higher requirements for waterproofness.

Charging cable:

For EV charging cables, the degree of friction on the ground is much higher than that of EV wallbox cables, and there is a greater possibility of contacting oil stains and other substances that may damage the cable sheath. Therefore, for the selection of portable EV charger’s cable materials, it is generally recommended to use TPU materials with better performance.

Wall end plug:

At present, the main wall plugs of portable EV chargers in the market include BS, Schuko, CEE, AU and NEMA. When customizing, customers can determine the wall plug according to the main target market. If you want to follow the high-end route and make the portable EV charger more widely applicable, we will suggest using it with an adaptive plug. This adapter has a convenient connection, high water resistance, and supports plug identification and temperature monitoring. It is very attractive for some customers who pursue high-quality products.

Unlike EV wallbox chargers, which uses a fixed power supply, portable EV charger will generally be used in different power consumption environments, so more situations need to be considered and the requirements for power safety will be higher.

The full link temperature control system, from the charger plug to the cable to the control box, constantly monitors the temperature of each part of the portable EV charger. Once the set temperature value is exceeded, the charging will be stopped immediately to ensure charger safety.

Self identifying adapter plug. For different adapter plugs, the control box can automatically set the maximum charging current to prevent customers from setting the wrong charging setting, which leads to a charging current greater than the power load at the wall end, resulting in power consumption hazards.

Classifications And Parameter Options Of A Portable EV Cable

These are some basic classifications and parameters of portable EV chargers. After these parameters are determined, the customization direction of portable EV chargers is basically determined. Of course, there are many other important parameters, which are only schematic. We will communicate with customers in detail to confirm the details of each parameter before customization, so as to ensure that the products fully meet the expectations of customers. What if the customer has just entered this field and is not sure about some parameters?

It doesn’t matter. We will design the most suitable parameter configuration of portable EV charger for customers according to their market positioning and needs.
