Primary Outlet
Plug your dryer or priority EV into the Primary outlet to provide power on-demand.
Secondary Outlet
The Secondary outlet is used for your EV charger. The Smart Splitter uses a set of relays to pause power to the Secondary outlet and avoid overloading the circuit.
EV Connector
There are two main types of EV connectors: J3400 (Tesla) and J1772. The NACS standard will be widely adopted in 2025 by other car manufacturers.
Easy Install with Mounting Bracket
No need to drill extra holes in your wall. The Smart Splitter comes with a bracket that screws into the existing wallplate to secure the Smart Splitter in place.
EVSE / EV Charger
The Electric Vehicle Supply Equpment (EVSE) are commonly know as "EV chargers". Level 2 Chargers use AC current to send power to the car. Chargers may be wall-mounted or free standing, depending on the design and intended use case.

How It Works & Safety
Dryer Takes Priority
Smart auto-switching means you no longer have to swap your plugs. The priority goes to the dryer (most common) or EV plugged into the primary outlet, when the dryer is finished your EV will begin charging.

Auto-Switching With 2 EVs
With two EVs plugged in at maximum amperage (32-40 amps) the Smart Splitter will fully charge the EV on the Primary side before switching to the EV on the Secondary side.

Dual EV Charging (Half Power)
Set your EV charger(s) or EV(s) to 20 amps or less (half power) to allow for simultaneous EV Charging. The Smart Splitter ensures both cars can charge at once without tripping the breaker.

Smart Charging With the NeoCharge App
I purchased the NEMA 10-30 to charge my Tesla model Y connected to my water heater. It is fantastic! Save yourself thousands of dollars with the electrician and get one of these. If your on the fence deciding if this would even work with your water heater, don’t, it is well worth the money spent and the device works as designed. I have no issues at all charging my car and have zero issues with having hot water. What are you waiting for, it works, you will be glad you made the purchase just like I did.
Amazing purpose built item.
I have been using a 14-50 NeoCharge now for over a year with both a BMW i4M50 and a Cadallic Lyriq and have never had any major issues at all. I set to charge the Lyriq daily from 8PM to 1AM and then charge the i4M50 to charge from 1AM to 8AM and both vehicles are fully charged (up to 80%) without any problems. The NeoCharge just works
Bought this instead of a ($3,600!!!!) quoted panel upgrade / rewiring project from the electrician. Saved over $3,000 to install charging and I dont even have to think about it. It just works and I've had zero issues with the dryer or EV for months.
Bought my Tesla Model 3 and Tesla charger only to discover my circuit box couldn’t handle an additional 240V circuit. Also the electric company meter and main circuit breaker couldn’t handle the increased voltage needed. This unit was the ideal solution! I use my current 240 V dryer plug- the smart plug can supply 240 V to either my charger or the dryer! No city permits to get, no $15k upgrade to my electric panel! This is sheer genius!!
Great product! Easy Setup!

Frequently Asked Questions
How does the Smart Splitter work?
The Smart Splitter works by intelligently sharing a single 240V outlet between an appliance and an EV charger or between two EV chargers. It uses power-sensing technology to automatically switch power between both outlets, ensuring safe and efficient operation.
For appliance and EV charger setups, the splitter prioritizes the appliance and resumes charging the EV when the appliance is not in use.
For two EVs, the Smart Splitter allows the primary EV to charge first and then automatically switches to charging the secondary EV. OR You can charge both simultaneously at half speed by setting custom current limits.
Can I use the Smart Splitter if my 240V outlet is far from where I park my EV?
Yes, If your 240V outlet is far from your EV parking spot, you have two options:
1) Use a 10 guage 240V high voltage extension cord (usually 10-25 feet) to reach your EV; or
2) Have an electrician install conduit from the outlet to your charging location. NeoCharge has partnered with Treehouse to provide effortless electrician installation in the case the outlet is too far.
What safety features and certifications does the Smart Splitter have?
The Smart Splitter is UL certified, ensuring it meets the highest safety standards in the industry.
It features a built-in software breaker that automatically shuts off power if the total power being drawn from both outlets exceeds the outlet's capacity, preventing overloading and short-circuiting.
If you have a 50 amp breaker the max amperage is 40 amps. If you have a 30 amp dryer circuit breaker then the max amperage is 24 amps.
This ensures the Smart Splitter adheres to National Electric Codes (NEC) by keeping the circuit power within 80% of the breaker amperage.
Where is the Smart Splitter built?
The Smart Splitter is diesigned and manufactured in the US.
