How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The Smart Splitter is for the house with a 240-volt outlet in the right place and no room in the panel for a new circuit. We have not tested one; this review uses NeoCharge's product page, linked at the foot of this page.

How it works

It plugs into your existing outlet and gives you two sockets: one for the dryer or range, one for the EV charger. It switches power between them automatically, so the two loads take turns instead of overloading the circuit. NeoCharge also offers it for two EVs sharing one outlet.

The 24-amp limit

What a 30 A dryer circuit allows

Continuous limit: 30 x 0.8 = 24 A

24 A x 240 V = 5,760 W, about 5.8 kW

At 3.5 mi/kWh: about 20 miles of range per hour

On a 50 A outlet with the 40 A version: 9.6 kW, about 34 miles per hour

The 80% rule is the same one Splitvolt's FAQ spells out for its splitters: 24 A on a 30 A dryer circuit, 40 A on a 50 A circuit. Set your charger to match, so the charger -- not the splitter's breaker -- is doing the limiting. Chargers for a 30-amp circuit.

Who should buy it

  • No room for a new circuit, and a dryer or range outlet where you park. Panel upgrades.
  • Renters with the landlord's permission to use an existing outlet. Chargers for renters.

Who should skip it

  • Your panel can take a new circuit. A dedicated EV circuit charges while the dryer runs, with one less device in the chain.
  • The outlet is outdoors or damp. NeoCharge lists the splitter for indoor use only.
  • You need more than 24 A from a 30 A outlet. No splitter changes that limit.

The Smart Splitter in full

Full published specifications, and the case against it.

1. The broadest outlet range

NeoCharge Smart Splitter

NeoCharge · NEMA 14-50 · 40 A / 9.6 kW

Plugs into an existing 240-volt outlet and switches power between your dryer and your EV automatically, so you get Level 2 charging without a new circuit. UL listed, and sold in a version for each common dryer and range outlet.

What is good

  • Avoids a new circuit, which can mean avoiding a panel upgrade
  • Switches between the two loads automatically
  • UL listed, with an internal breaker that enforces the circuit limit
  • A version for every common dryer and range outlet type

What is not

  • The dryer and the charger take turns on the circuit
  • On a 30 A dryer circuit you are limited to 24 A of charging
  • You must buy the version that matches your outlet exactly

Skip this if: Skip it if your panel can take a new circuit. A dedicated EV circuit is simpler, charges while the dryer runs, and has one less device in the chain.

Alternatives

The Splitvolt Splitter Switch is the other listed option; both are compared in dryer outlet splitters.

FAQ

Questions people actually ask

Is the NeoCharge Smart Splitter worth it?
If the alternative is a new circuit or a panel upgrade, often yes. If your panel can take a dedicated EV circuit, that is simpler and charges while the dryer runs.
Can the dryer and the EV run at the same time on a NeoCharge?
No. It switches power between the two automatically, so they take turns.
How fast does a NeoCharge charge on a dryer outlet?
On a 30 A dryer circuit, up to 24 A -- about 5.7 kW, or roughly 20 miles of range an hour. The 40 A versions for 50 A outlets reach 9.6 kW.
Can I use a NeoCharge outdoors?
No. NeoCharge lists the Smart Splitter for indoor use only.
