Easee One vs Cord Zero: Which Budget Charger Deserves Your Wall?

Easee One vs Cord Zero: £150 Apart, But Worlds Apart on Features

Two of the most affordable smart chargers on the UK market, and both pack in built-in 4G — a feature you'd normally associate with pricier units. So what does the Cord Zero's extra £150 actually buy you?

The Easee One is a minimalist's dream: tiny, featherweight, and laser-focused on doing one thing well at the lowest possible price. The Cord Zero spends that premium on smart tariff integration, a tethered cable, and a broader feature set that tries to compete with chargers costing significantly more.

In a nutshell:

• Easee One (£405): Cheapest smart charger available, absurdly light at 1.5 kg, lifetime 4G included, untethered design
• Cord Zero (£555): EV tariff integration with Octopus Go and others, tethered convenience, dual Wi-Fi + 4G failover, promotional 5-year warranty

Is the Cord Zero's Smart Tariff Support Worth £150 More?

This is the single biggest functional gap between these two chargers. The Cord Zero connects to EV tariffs from Octopus Go, OVO, British Gas, and EDF through its Cord AI app, automatically scheduling your charging around cheaper rate windows. The Easee One has scheduled charging but no direct tariff integration — you set the times manually.

If you're on a flat-rate energy tariff or you already use your Tesla's built-in scheduling (which handles Octopus Intelligent Go natively), this advantage evaporates. But if you're on Octopus Go, OVO, or another supported tariff and you want the charger itself to handle optimisation, the Cord Zero delivers something the Easee simply cannot. Over a year of charging, the savings from automated off-peak scheduling can comfortably outweigh that £150 price difference. Check our EV tariff comparison to see what you could save.

Tethered vs Untethered: More Than Just Preference

The Easee One is untethered — a Type 2 socket on the wall. You plug in using the cable that came with your Tesla (or any Type 2 cable you own). It keeps the wall mount tiny and clean, but it means fetching the cable from your boot every time.

The Cord Zero comes tethered with a 5-metre cable as standard (8 metres for £625, or an untethered version at £475). For daily use, a permanently attached cable is simply more convenient — uncoil, plug in, walk away. If you're comparing like-for-like on the untethered models, the price gap shrinks to just £70, which makes the Cord Zero's extra features look like a bargain.

Worth noting for anyone with a longer driveway or awkward parking: the Cord Zero's 8-metre option at £625 solves a problem many chargers ignore entirely.

Connectivity and Reliability: Both Excellent, Cord Zero Slightly Better

Both chargers include built-in 4G — unusual at this price point and a genuine advantage over chargers that rely solely on your home Wi-Fi. The Easee One's lifetime eSIM means zero ongoing connectivity costs, ever. The Cord Zero matches with its own multi-network SIM but adds automatic failover between Wi-Fi and 4G, giving it arguably the most robust connection of any charger in this price bracket.

In practice, either will stay connected reliably in a detached garage or at the end of a long garden. If your Wi-Fi is strong at the charger location, the difference is academic. If it's patchy, both handle it far better than most competitors.

Installation and Build: The Easee One Is Ridiculously Light

At 1.5 kg, the Easee One weighs less than some laptops. Your installer will thank you — it mounts on virtually any wall surface without heavy-duty fixings. Both chargers include integrated RCD and PEN fault protection, which can save £100+ on your installation by eliminating the need for additional consumer unit components.

The Cord Zero at roughly 5 kg is still compact, and its IK08 impact resistance rating gives it an edge in durability if your charger is exposed to knocks from bikes, bins, or wayward footballs. Standard installation costs are comparable: £400–600 for the Easee One, £400–500 for the Cord Zero.

Both carry a 3-year warranty, though the Cord Zero currently offers a free upgrade to 5 years — a promotional deal that may not last. If longevity matters to you, that's a meaningful sweetener while it's available.

Which Should You Buy?

Buy the Easee One if:

• You want the absolute lowest purchase price at £405
• You prefer a clean, untethered wall mount and don't mind using your own cable
• You're already on Octopus Intelligent Go (your Tesla handles scheduling)
• You want the simplest, lightest installation possible

Buy the Cord Zero if:

• You want smart tariff integration with Octopus Go, OVO, or other supported providers
• You prefer a tethered cable for daily plug-and-go convenience
• You value the current 5-year warranty promotion
• You need an 8-metre cable option for a longer run

For pure value, the Easee One is hard to argue with — it's the cheapest smart charger on the market and does the basics brilliantly. But if you're planning to save money through smart tariff automation, the Cord Zero pays for its premium over time and gives you a more complete package. For most Tesla owners who want a set-and-forget experience with genuine bill savings, the Cord Zero earns the extra spend.
