The NeoCharge Smart Splitter is a device designed to simplify home EV charging by enabling safe, cost-effective, and effortless access to existing 240V outlets without requiring expensive rewiring or panel upgrades. It acts as an intelligent power management system, allowing two high-power appliances or electric vehicles (EVs) to share a single 240V circuit.

Function Description:

The core function of the Smart Splitter is to monitor the total power draw from both connected outlets and automatically manage power distribution to prevent circuit overload. It prioritizes power to a designated "Primary" outlet while intelligently switching power to a "Secondary" outlet when the Primary device is not actively drawing high power. This automated switching ensures that the combined load does not exceed the circuit's limit, thereby maintaining electrical safety and preventing tripped breakers.

For EV charging, the Smart Splitter allows users to plug in two EV chargers into a single 240V outlet. When one EV is charging (connected to the Primary outlet), the Smart Splitter ensures it receives power. Once the Primary EV finishes its charging session or reduces its power draw, the Smart Splitter automatically switches power to the Secondary outlet if another EV is connected and attempting to charge. This eliminates the need for manual switching or costly electrical upgrades to support two dedicated EV charging circuits.

Beyond EV charging, the Smart Splitter can also manage power between an EV charger and a high-power appliance, such as a clothes dryer. In this scenario, the appliance would typically be connected to the Primary outlet. When the appliance starts drawing power, the Smart Splitter automatically pauses EV charging from the Secondary outlet. Once the appliance finishes its cycle, EV charging automatically resumes. This "Appliance Auto-Switching" feature provides convenience and ensures that essential household appliances can operate without interruption while still allowing for EV charging.

The device operates with a "minimal amount of power" always available to the Primary outlet, even when the Secondary is active. This "idle mode" is specifically designed to power LED screens or allow for interaction with the Primary device, enabling it to be turned on, which will then completely shut off the Secondary. This ensures that devices connected to the Primary outlet remain responsive and functional even when the Secondary is drawing power.

Usage Features:

Automated Power Switching: The Smart Splitter automatically manages power distribution between two connected devices, eliminating the need for manual intervention. This is crucial for both dual EV charging and EV charging alongside a high-power appliance.
Circuit Overload Prevention: By continuously monitoring power draw and intelligently switching between outlets, the device prevents the circuit from being overloaded, ensuring safety and protecting electrical infrastructure.
"Plug-and-Play" Installation: The installation process is designed to be straightforward, involving turning off the circuit breaker, installing a mounting bracket to the existing 240V outlet, plugging in the Smart Splitter, and then connecting the Primary and Secondary devices.
Flexible Mounting Options: The Smart Splitter offers two types of screws for securing it to the mounting bracket: thumb screws for quick plug-and-play and panhead screws for a lower profile, which can be useful if larger plugs or cords might interfere.
Clear LED Indicators: The device features LED lights that provide immediate visual feedback on its operational status:
- White: Indicates idle mode or that the device is on.
- Green: Signifies that an outlet is actively receiving power.
- Yellow: Shows that charging is paused.
- Blue (flashing): Indicates WiFi pairing mode, active for the first 5 minutes after a power cycle.
- Red: Signals an error, typically indicating that charging has stopped and the current limit should be lowered.
Simultaneous EV Charging (50A Breaker Only): For users with a 50A breaker and two EVs/EVSEs with adjustable amperage, the Smart Splitter allows for simultaneous charging of both EVs at half power (up to 20A each, not exceeding a total of 40A). This feature provides flexibility for households with multiple electric vehicles.
Primary Outlet Priority: The device connected to the Primary outlet always takes priority. This is typically the appliance (like a dryer) or the EV that the user wishes to charge first.
Compatibility with Various Outlet Types: The manual provides guidance for installing the mounting bracket with different NEMA outlet types (10-30, 14-30, 14-50, 6-50, 10-50), including notes for older faceplates or non-standard orientations.
Smart Home Integration (Upcoming): The manual mentions an upcoming "NeoCharge Connect app" for exclusive early access, suggesting future capabilities for optimizing home energy usage, increased savings, insights, and control, starting with EV charging. This indicates potential for remote monitoring and management.

Maintenance Features:

Self-Monitoring for Defects: The device is designed to be robust, but users are advised to discontinue use if it appears cracked, frayed, broken, or otherwise damaged, or fails to operate.
No User Servicing: Users are explicitly warned not to attempt to open, disassemble, repair, tamper with, or modify the Smart Splitter. The device is not user-serviceable, and any repairs should be handled by NeoCharge Support.
Environmental Protection: Users are instructed to avoid exposing the device to foreign objects, moisture, and water. If corrosion or damage is suspected due to moisture, use should be discontinued immediately. It should not be plugged into outlets submerged in water or covered in snow.
Proper Storage Guidelines: The device should be stored in a clean and dry place within specified temperature ranges (-40° F to 185° F / -40° C to 85° C) to ensure longevity.
Cleaning Precautions: Users are advised to avoid the use of cleaning solvents with the device.
Warranty Support: The Smart Splitter comes with a 2-year limited warranty covering defects in materials and workmanship, shipping damage, and necessary repair/replacement costs. NeoCharge's customer support team is available to troubleshoot issues and facilitate returns/replacements if the device is found to be defective.
Troubleshooting Resources: NeoCharge provides comprehensive troubleshooting assistance through their website, including a chat button for step-by-step troubleshooting flows and direct support from EV charging experts. This ensures users have access to help for common concerns or more complex issues.
