One of the biggest barriers to installing a home EV charger is the cost of electrical upgrades. Running a new 240V circuit can easily cost thousands, depending on your home setup.
The Splitvolt NEMA 14-30 Splitter Switch offers a clever workaround: it lets you share your existing dryer outlet with your EV charger, eliminating the need for expensive electrical work.

Use Your Existing Dryer Outlet for EV Charging
Most homes already have a 240V dryer outlet (NEMA 14-30) installed.
Instead of installing a new circuit, this splitter allows you to:
- Share the same outlet between your dryer and EV charger
- Automatically switch power between devices
- Avoid costly electrician installation
This makes it one of the fastest and cheapest ways to get Level 2 charging at home.
Automatic Power Switching (No Manual Plugging)
The Splitvolt switch intelligently manages power between two devices.
- If the dryer is running → EV charging pauses
- When the dryer stops → EV charging resumes
This means:
- No need to unplug/replug cables
- No risk of overloading the circuit
- Seamless day-to-day usage
It can also work with two EV chargers, sharing power safely between them.
Plug-and-Play Setup (No Electrician Needed)
Installation is simple:
- Plug the Splitvolt into your dryer outlet
- Connect your dryer and EV charger
- Start charging
That’s it. No rewiring, no installation work.
For most users, this means you can set up Level 2 charging in minutes.
