Halo is a Level 2 home charging station made by Wallbox
Halo is a Level 2 electric vehicle charger manufactured by Wallbox, a Spanish company that makes residential and commercial charging equipment. It mounts on your wall, connects to a 240-volt circuit in your home, and charges most EVs in 4 to 10 hours depending on battery size and the charger's power output. Halo is not a fast charger — those are DC fast chargers found at public stations — but it is designed for overnight charging at home.
The charger comes in two versions: Halo X and Halo S. Both connect via WiFi to a smartphone app that lets you monitor charging, set schedules, and receive notifications. Halo chargers are UL-certified for safety and work with most EV models sold in North America, including Tesla (with an adapter), Chevrolet, Ford, Hyundai, Kia, and others.
Key Takeaways
- Halo is a wall-mounted Level 2 charger that requires a dedicated 240-volt circuit and professional installation, which typically costs $500 to $2,000 depending on your home's electrical setup.
- The Halo X outputs up to 11.5 kW and the Halo S outputs up to 7.4 kW, with the difference affecting how quickly your vehicle charges overnight.
- Both models include WiFi connectivity and a smartphone app to schedule charging during off-peak hours and monitor charging sessions in real time.
- Installation must be performed by a licensed electrician, and some states and utilities offer rebates or tax credits that can offset the purchase and installation cost.
Halo X versus Halo S: power output and features
The Halo X is the higher-powered model, delivering up to 11.5 kilowatts. It charges faster than the Halo S and is better suited to owners with larger batteries or shorter charging windows. The Halo X requires a 60-amp circuit and costs more upfront than the Halo S.
The Halo S delivers up to 7.4 kilowatts and requires a 40-amp circuit. It is less expensive and sufficient for most owners who charge overnight. Both models include the same app features, weatherproof design, and safety certifications. Your choice depends on your vehicle's maximum charging rate, your electrical panel's capacity, and your budget.
Check your vehicle's manual or the manufacturer's website to find its maximum charging rate — this is the limiting factor. If your car can only accept 7.4 kW, buying the Halo X will not charge it any faster.
Installation requirements and costs
Halo chargers must be installed by a licensed electrician. The electrician will run a new 240-volt circuit from your electrical panel to the wall location where you want the charger mounted. Installation cost ranges from $500 to $2,000 depending on the distance from your panel to the charger location, whether your panel has available breaker space, and local labor rates.
Before purchasing a Halo charger, have an electrician inspect your electrical panel to confirm it can support a new 240-volt circuit. Some older homes may need a panel upgrade, which adds significant cost. Your electrician can provide a quote after this inspection.
The charger itself costs between $600 and $1,200 depending on the model and where you purchase it. Some retailers and utilities offer discounts or bundle deals that include installation.
Rebates, tax credits, and incentive programs
The federal government does not currently offer a direct rebate for purchasing a Level 2 charger, but some states, utilities, and local governments do. California, New York, Colorado, and several other states have programs that cover part of the charger cost or installation. Check your state's energy office website or your utility's website for current programs.
Some employers and workplaces also offer charging incentives as part of employee benefits. If you are buying a new EV, the dealer may have information about local charger rebates or financing options.
Incentive programs change frequently and have funding limits, so contact your utility or state energy office directly to learn what is currently available in your area. Provide your zip code and utility name when you inquire.
WiFi connectivity and the Halo app
Both Halo models connect to your home WiFi network and pair with the Wallbox app on your smartphone. The app shows real-time charging status, energy consumption, and charging history. You can set charging schedules to start and stop at specific times, which is useful if your utility offers lower rates during off-peak hours.
The app also includes a feature called "Eco-Smart" that can delay charging until renewable energy is available on the grid in your area, though this feature's availability depends on your region and utility. You can receive push notifications when charging begins, completes, or if a fault occurs.
If your WiFi goes down, the charger will still function — it just will not communicate with the app or respond to remote commands. You can still plug in and charge manually.
Compatibility with different EV models
Halo chargers use the SAE J1772 connector, the standard Level 2 plug in North America. Most EVs come with a J1772 cable or adapter. Tesla vehicles require a separate J1772 adapter (sold by Tesla or third-party makers) to use Halo or any non-Tesla Level 2 charger.
Halo works with Chevrolet Bolt, Ford Mustang Mach-E, Hyundai Ioniq, Kia EV6, Nissan Leaf, Volkswagen ID.4, and most other EVs sold in the United States and Canada. Check your vehicle's manual or the Wallbox website to confirm compatibility before purchasing.
Maintenance and safety features
Halo chargers require minimal maintenance. The weatherproof housing protects the internal components, and there are no moving parts to wear out. Wallbox recommends checking the cable and connector for damage before each use and keeping the charger dry.
Both models include ground fault protection, overcurrent protection, and temperature monitoring to prevent overheating. If a fault is detected, the charger stops charging and sends an alert to your phone. The charger is designed to operate safely in temperatures from -4°F to 122°F.
Wallbox offers a three-year warranty on Halo chargers covering defects in materials and workmanship. Extended warranty options may be available through retailers or directly from Wallbox.
Frequently Asked Questions
Can I install a Halo charger myself?
No. Halo chargers must be installed by a licensed electrician because they require running a new 240-volt circuit from your electrical panel. Improper installation can create fire and shock hazards. Your electrician will also may support the installation meets local electrical codes and building permits.
How long does it take to charge a full battery with Halo?
Charging time depends on your vehicle's battery size and the Halo model. A typical EV with a 60 kWh battery will charge in 5 to 8 hours on a Halo X and 8 to 11 hours on a Halo S. Smaller batteries charge faster, and larger batteries take longer. Your vehicle's manual lists its maximum charging rate, which determines the actual speed.
What if I move to a new house?
Halo chargers are hardwired to your home's electrical system and cannot be easily moved. If you relocate, you would need to leave the charger behind or hire an electrician to remove and reinstall it at your new home. Some homeowners leave the charger as part of the home sale, as it increases the property's value to EV owners.
Does Halo work with solar panels or a home battery?
Yes, Halo can be integrated with solar systems and home batteries like Tesla Powerwall, though this requires additional equipment and programming. Your electrician and solar installer can design a system that charges your vehicle using stored solar energy. This setup is more complex and costly than a standard installation.
What happens if the power goes out?
If your home loses power, the Halo charger will not function until power is restored. Your vehicle will not charge during an outage. If you have a home battery system, you may be able to configure it to power the charger during an outage, but this requires a specialized setup designed by your installer.
