Easee One vs Sync Energy Wall Charger 2: Budget Battle

Two of the Cheapest Smart Chargers in the UK — But Which One Deserves Your Wall?

Below £500 for the unit alone, both the Easee One and Sync Energy Wall Charger 2 sit firmly in budget territory. They deliver the same 7.4kW single-phase output, both include built-in PEN fault protection (no earth rod needed), and both carry a 3-year warranty. On paper, they look almost interchangeable. In practice, they're aimed at slightly different buyers.

In a nutshell:

• Easee One (£405): Bulletproof connectivity via lifetime 4G, absurdly light at 1.5 kg, and the tidiest untethered design on the market.
• Sync Energy Wall Charger 2 (from £302): The lower entry price, integrated solar diversion, smart tariff scheduling, and a tethered option with a 7.5m cable.

Does the Easee One's Built-in 4G Actually Matter?

More than you'd think. The Easee One ships with a lifetime 4G eSIM — no subscription, no renewal, no fiddling. Wi-Fi is there as backup, but the cellular connection means your charger stays online even if your router is three walls away in the loft.

The Sync Energy relies on Wi-Fi (plus Ethernet and Bluetooth for setup). That's fine if your router is close to the driveway, but multiple user reviews flag Wi-Fi reliability issues at range. You can upgrade to the GG variant for 4G, but that costs extra and narrows the price gap with the Easee. If your charger is going on an external wall far from your router, the Easee's always-on 4G is a meaningful advantage you won't have to think about again.

Is the Sync Energy Worth It for Solar Panel Owners?

This is where the Sync Energy pulls away. Its SolarCharge feature uses a CT clamp to monitor your solar generation and divert surplus energy to your car. The Easee One has no solar diversion capability at all.

If you've got panels on the roof and want to maximise self-consumption, the Sync Energy is the obvious choice here — and at a lower price point too. For a deeper look at solar-compatible chargers, see our best EV charger for solar panels guide.

Connectivity, Apps, and Smart Tariff Support

The Sync Energy's TariffSense scheduling is designed to optimise charging around time-of-use tariffs, and its OCPP 1.6J compliance means it can talk to third-party energy management platforms down the line. That's a forward-thinking inclusion at this price.

The Easee app handles scheduled charging perfectly well, and dynamic load balancing works across up to three Easee chargers on one fuse — handy for households with two EVs. But it lacks a dedicated smart tariff feature comparable to TariffSense, and there's no OCPP support. For most Tesla owners using the Tesla app's built-in scheduling, this won't matter. But if you're the sort of person who wants granular control through your energy platform, the Sync Energy offers more flexibility.

The 1.5 kg Question: Installation and Design

At 1.5 kg, the Easee One is comically light. Your installer will thank you. It's the smallest charger we cover, and the untethered socket design means no cable hanging on your wall when the car isn't plugged in. It looks clean. The trade-off: you carry your own cable each time, though every Tesla ships with one.

The Sync Energy is a chunkier unit at 4–5 kg with a more utilitarian look, but it counters with IP65 and IK10 ratings — that's full weatherproofing plus impact resistance, a step above the Easee's IP54. If your charger is exposed to the elements or in a spot where it might get knocked, the Sync Energy is the tougher unit. The interchangeable fascia plates in nine colours are a nice touch too, letting you match your brickwork or front door.

Which Should You Buy?

Buy the Easee One if:

• Reliable connectivity matters and you don't want to worry about Wi-Fi range
• You prefer a minimal, untethered wall mount with the lightest possible install
• You want lifetime 4G included in the price with zero ongoing costs
• You value the Easee ecosystem for multi-charger load balancing

Buy the Sync Energy Wall Charger 2 if:

• You have solar panels and want built-in solar diversion without paying more
• You want a tethered charger with a 7.5m cable from just £302
• OCPP support and future energy platform integration appeal to you
• You need a tough, impact-resistant unit for an exposed location

For most Tesla owners without solar panels, the Easee One at £405 is the smarter buy. The 4G connectivity alone saves potential headaches, and the installation is about as painless as it gets. But if you've got solar or you're on a tight budget, the Sync Energy's combination of a lower starting price and genuine energy management features makes it hard to ignore.
