Wallbox Pulsar Max vs Cord Zero

The Wallbox Pulsar Max is £59 cheaper at £496 compared to the Cord Zero at £555. The Cord Zero price is tethered 5m; 8m version £625; untethered £475.

When you factor in professional installation (typically £400–£600), the total installed cost for the Wallbox Pulsar Max is approximately £896–£1096, while the Cord Zero comes in at around £955–£1155. Fully installed, the Wallbox Pulsar Max remains the more affordable option.

The Wallbox Pulsar Max (7.4kW / 22kW) supports three-phase charging at up to 22kW, while the Cord Zero is single-phase only at 7.4kW. On the standard UK single-phase supply (95% of homes), both charge at roughly the same speed. Three-phase is only relevant if your property has a three-phase electrical supply.

On a standard UK single-phase supply, both will charge a Tesla Model 3 Long Range (75kWh battery) from 20% to 80% in approximately 5–6 hours overnight. Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.

The Wallbox Pulsar Max offers: myWallbox app, Scheduled charging, Power Boost (dynamic load balancing), Bluetooth & Wi-Fi, Eco-Smart (solar integration), Voice control (Alexa/Google). The Cord Zero offers: Cord AI app, Scheduled charging, EV tariff integration, Solar compatible, Dynamic load balancing, RFID access control, OCPP 1.6J, Wi-Fi + 4G dual connectivity, Energy monitoring.

Breaking these down by category: for connectivity, the Wallbox Pulsar Max uses Bluetooth & Wi-Fi, while the Cord Zero uses Wi-Fi + 4G dual connectivity. For energy management, the Wallbox Pulsar Max provides Power Boost (dynamic load balancing), compared to the Cord Zero's Dynamic load balancing, Energy monitoring. Solar and scheduling features are covered in the dedicated sections below.

Both the Wallbox Pulsar Max and Cord Zero support solar integration, allowing you to charge your Tesla using surplus solar energy rather than drawing from the grid. The implementation and sophistication of solar diversion differs between the two, which can significantly affect how much free charging you actually get.

The Wallbox Pulsar Max uses its Eco-Smart feature with a power meter sensor to detect surplus solar and adjust charging power in real time. The Cord Zero supports solar diversion through its energy management system. The key difference is how precisely each charger tracks surplus generation — CT clamp-based systems typically offer more responsive diversion than those relying on smart meter data, which can have a slight delay.

The Cord Zero integrates with smart energy tariffs, automatically charging at the cheapest off-peak rates. The Wallbox Pulsar Max doesn't have built-in smart tariff integration — you'd need to set manual charging schedules or rely on your car's built-in timer. If you're on (or considering) a smart tariff, this gives the Cord Zero a meaningful advantage in running costs.

The Cord Zero supports smart tariff scheduling with popular EV tariffs including Octopus Go (~8.5p/kWh) and similar time-of-use plans. The most popular UK EV tariffs include Octopus Intelligent Go (~7p/kWh), Octopus Go (~8.5p/kWh), OVO Charge Anytime (~14p/kWh), and British Gas EV Power+ (~7.9p/kWh). Check compatibility with your specific energy provider before making a decision.

The Wallbox Pulsar Max comes with a 5 years warranty, while the Cord Zero offers 3 years. The Wallbox Pulsar Max offers 2 years more coverage, giving you added peace of mind. Both are OZEV-approved and suitable for outdoor installation — a longer warranty provides more peace of mind for a product that lives outside year-round and is exposed to British weather.

For weatherproofing, the Wallbox Pulsar Max is rated IP54 + IK10 (weatherproof + impact-resistant) (splash-proof — protected against splashing water from any direction), while the Cord Zero is rated IP54 + IK08 (weatherproof, impact-resistant) (splash-proof — protected against splashing water from any direction). A higher IP rating means better protection against rain, hose water, and dust. In practical terms, any rating of IP54 or above is suitable for a UK outdoor installation, but a higher rating provides extra confidence in extreme weather — particularly relevant if your charger is exposed rather than sheltered under a car port.
