Cord Zero vs EcoFlow PowerPulse 2

The EcoFlow PowerPulse 2 is £10 cheaper at £545 compared to the Cord Zero at £555. Note: the EcoFlow PowerPulse 2 price is untethered; tethered 5m also available. 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 Cord Zero is approximately £955–£1155, while the EcoFlow PowerPulse 2 comes in at around £945–£1145. Fully installed, the EcoFlow PowerPulse 2 remains the more affordable option.

The EcoFlow PowerPulse 2 (7kW / 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 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. The EcoFlow PowerPulse 2 offers: EcoFlow app, Solar Mode (prioritises surplus solar), Smart Mode (dynamic tariff optimisation), Scheduled charging, Real-time load balancing, RFID authentication, LCD status display, OCPP 1.6-J, OTA updates.

Breaking these down by category: for connectivity, the Cord Zero uses Wi-Fi + 4G dual connectivity, while the EcoFlow PowerPulse 2 uses its companion app. For energy management, the Cord Zero provides Dynamic load balancing, Energy monitoring, compared to the EcoFlow PowerPulse 2's Real-time load balancing. Solar and scheduling features are covered in the dedicated sections below.

Both the Cord Zero and EcoFlow PowerPulse 2 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 Cord Zero supports solar diversion through its energy management system. The EcoFlow PowerPulse 2 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.

Both the Cord Zero and EcoFlow PowerPulse 2 support smart energy tariffs, enabling automated off-peak charging at significantly reduced rates. This is one of the most impactful ways to cut your EV running costs, potentially saving hundreds of pounds per year compared to charging on a standard tariff.

The Cord Zero supports smart tariff scheduling with popular EV tariffs including Octopus Go (~8.5p/kWh) and similar time-of-use plans. The EcoFlow PowerPulse 2 supports smart tariff scheduling with popular EV tariffs including Octopus Go (~8.5p/kWh) and similar time-of-use plans. The most popular EV tariffs in the UK include Octopus Intelligent Go (~7p/kWh), Octopus Go (~8.5p/kWh), OVO Charge Anytime (~14p/kWh), and British Gas EV Power+ (~7.9p/kWh). Not all chargers work with all tariffs, so check compatibility with your specific provider before buying.

The Cord Zero comes with a 3 years warranty, while the EcoFlow PowerPulse 2 offers 3 years. Both offer the same warranty length, so neither has an advantage here. The Cord Zero is OZEV-approved; the EcoFlow PowerPulse 2 is not. Both are 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 Cord Zero is rated IP54 + IK08 (weatherproof, impact-resistant) (splash-proof — protected against splashing water from any direction), while the EcoFlow PowerPulse 2 is rated IP55 (IP54 when cable not connected) (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.
