A dual port EV charger is a single charging station with two connectors, so it can charge two vehicles at the same time. Both ports usually share one power supply and one installation, which makes it cheaper per parking space than two separate chargers. When both cars are plugged in, the station either gives each port its full rating or splits the available power between them, depending on the design and the circuit.
How a Dual Port Charger Works
Inside the station, each port has its own control electronics and connector, but they share the incoming supply, the enclosure and often the network connection. Many dual port units use power sharing: if one car is charging, it can take up to the per-port maximum; when a second car plugs in, the station divides the total between the two. Smart chargers can also adjust as one car finishes, sending more power to the other.
This is closely related to load balancing. Our guide to whether load balancing increases charging speed explains why sharing power does not make any single car charge faster.
Dual Port vs Two Single Chargers
| Factor | One dual port station | Two single chargers |
|---|---|---|
| Spaces served | Two | Two |
| Installation | One mount, one supply run | Two mounts, often two circuits |
| Power when both in use | Shared or full per port, by design | Full per charger if each has its own circuit |
| Network and billing | One device to manage | Two devices |
| If the unit fails | Both spaces may be affected | Only one space is affected |
| Best for | Lots where spaces sit side by side | Spaces far apart |
Who Uses Dual Port Chargers
- Businesses and workplaces that want to serve more spaces per installation.
- Apartment and condo sites with shared parking.
- Hotels and restaurants where guests park for an hour or longer.
- Two-EV households with a shared driveway; see how two-EV households can charge smarter.
How to Choose a Dual Port EV Charger
Rather than looking for a single “best” model, check how a charger fits your site:
- Total and per-port power: read the datasheet for both numbers, and how power is split when two cars charge.
- Supply: single-phase or three-phase, and the circuit size your building can support. A licensed electrician should confirm this.
- Connector type: Type 2 for Europe and many other markets; J1772 or NACS in North America.
- Tethered or socketed: fixed cables are convenient; sockets let drivers use their own cable.
- Access control and OCPP: RFID and OCPP let you manage users and billing through your chosen platform.
- Weather rating and certification: check the IP rating for outdoor sites and the certification your market requires.

EVDANCE Dual-Gun Station
The EV-AC03201T dual-gun AC station has two Type 2 guns with up to 43 kW shared and up to 22 kW per gun. It supports OCPP 1.6J and RFID and is rated IP54. For single spaces, the EV-ACT3204E 22 kW wallbox is a three-phase option. Distributors and brands can explore the distributor program.
Frequently Asked Questions
Does a dual port charger charge two cars at full speed?
It depends on the model and the circuit. Some give each port its full rating; many share a total, so each car gets less when both charge.
Can a dual port charger work with any EV?
It works with any EV that accepts its connector type, or with an approved adapter. The car’s onboard charger also limits AC charging speed.
Is a dual port charger good for home use?
It can suit homes with two EVs, if the electrical supply can support it. Many homes use one charger with scheduling instead.
