Key Takeaways

Best for: Level 2 charging with no new circuit
Standout: Plug-in sharing of an existing dryer outlet
Watch out: EV charging capped at 24A
Not for: Homes with a dryer far from the parking spot

The Splitvolt Splitter Switch plugs into a 240V NEMA 14-30 dryer outlet and lets your dryer and a Level 2 EV charger share it safely. It pauses EV charging while the dryer runs and caps the car at 24A. It sells for about $370 to $410.

What you need before you buy

A NEMA 14-30 dryer outlet close to where you park (Splitvolt sells a 10-30 version for older outlets).
A Level 2 EV charger with a 14-30 plug or adapter, set to 24A or less.
No electrician: it plugs in.

Why it can replace a panel upgrade

A new 50A EV circuit can push a full panel past its limit. Sharing the dryer circuit adds no new load, since the dryer and car never draw power at the same time.

Splitvolt Splitter Switch (NEMA 14-30, 24A)

The Splitvolt Splitter Switch lets an EV charger share your dryer outlet, often avoiding a new circuit or panel upgrade. Here is who it suits.

Product Brand: Splitvolt

Editor's Rating:
4.4

Pros

Shares your existing 240V dryer outlet with an EV charger, so you may not need a new circuit
Plugs in with no electrical installation
Automatically pauses EV charging while the dryer runs
Built-in safety breaker caps EV charging at 24A
Display shows real-time power use

Cons

EV charging is limited to 24A (about 5.8kW), slower than a dedicated 40A or 48A circuit
Only works with NEMA 14-30 dryer outlets (other models for 10-30)
The dryer outlet must be near where you park
Costs nearly as much as a basic Level 2 charger

Specs

Model	SPS-02-022-30A
Outlet type	NEMA 14-30 (dryer)
Voltage	240V
EV charging limit	24A (internal safety breaker)
Priority	Dryer first; EV charging pauses automatically
Display	Real-time power usage
Install	Plug-in, no electrician needed
Certification	cETLus
Weight	9.2 lb

Verdict

The Splitvolt is a clever, safe way to get Level 2 charging from a dryer outlet you already have, often saving the cost of a new circuit or panel upgrade. Charging tops out at 24A, so if you can add a dedicated 50A circuit, a 40A charger will be faster.

Common Questions

Do I need an electrician?: No. It plugs into your existing NEMA 14-30 dryer outlet, and your dryer and EV charger plug into it.
What happens when the dryer runs?: EV charging pauses automatically and resumes when the dryer finishes, so the circuit is never overloaded.
How fast will my EV charge?: At 24A, about 18 to 22 miles of range per hour for most EVs, enough to refill a typical commute overnight.
