Buyer’s Guide: What to Consider

When choosing a load management device for two EVs, focus on your home’s electrical capacity, charging speed, and smart features. Here are key factors to consider.

• Electrical Panel Capacity: Check your home's service size (e.g., 60A, 100A). If it's low, a load management device like BLACKBOX can avoid upgrades.
• Charging Speed Needs: Consider how many miles you drive daily. Higher amperage (48A) charges faster but may require more electrical capacity.
• Smart Features: Apps, scheduling, and RFID add convenience and security, especially for shared households. Decide which features matter to you.
• Installation Type: Plug-and-play (NEMA 14-50) is easier, while hardwiring can support higher amperage. Choose based on your electrical setup.
• Cable Length and Management: Longer cables reach both vehicles, but consider a holder like EV Hover to keep them organized and safe.

Conclusion

Managing two EVs at home doesn’t have to be stressful. Whether you need to avoid a panel upgrade with the BLACKBOX, prefer smart controls with TopAutoGear, or want a simple cable holder, there’s a solution for every need.

Assess your electrical setup and charging habits, then pick the device that fits best. With the right load management, you’ll charge both cars efficiently and safely.
