Sync Energy Wall Charger 2 vs Indra Smart LUX: the £253 question

The £253 question

Two tethered 7.4kW chargers, both OZEV-approved, both single-phase. The Sync Energy Wall Charger 2 is £362. The Indra Smart LUX is £615. That £253 gap is not about power, features or tariff cleverness — both do the core job. It is about build, proportions and where the thing was made.

• Sync Energy Wall Charger 2 — the budget tethered pick, with the longest cable in its class and solar diversion included.
• Indra Smart LUX — 78 mm deep, IP67-sealed, built in Worcestershire; the premium goes on the metal and the engineering behind it.

What the extra £253 actually buys

Strip the feature sheets side by side and the functional overlap is considerable. Both run at 7.4kW. Both handle dynamic load balancing, solar PV diversion via CT clamp, OCPP 1.6, OTA updates and energy monitoring. Both carry a three-year standard warranty. Neither has a direct tariff API — they schedule rather than negotiate in real time.

So what does £253 get you? Three things. First, the physical object: the Smart LUX is 78 mm deep, the thinnest tethered smart charger sold in the UK. If your wall is narrow, by a doorway, or visible from the street, that matters. Second, the protection rating: IP67 against IP65, IK10 on both. IP67 is submersible; IP65 is weatherproof. For most UK installations, IP65 is ample. For a coastal property or an exposed wall facing the prevailing wind, IP67 is reassurance you can actually point at. Third, the provenance — UK design and manufacture in Worcestershire, backed by Indra's own engineering team, versus Sync Energy's position under Luceco PLC.

None of those is a feature you'll use on a Tuesday morning. They are the reasons you pay more for a thing that lasts.

Where the Sync Energy wins on paper

Cable length is the one spec where the cheaper charger beats the dearer one outright. The Sync Energy Wall Charger 2 ships with 7.5 metres as standard. The Smart LUX starts at 6 metres; a 10-metre version exists but pushes the price up further. If your charger is going on a side wall and the car parks at the far end of the drive, that's the difference between reaching the charge port comfortably and dragging cable across a bonnet.

The fascia plates are a minor thing, but the kind of minor thing that earns goodwill. Nine interchangeable colours, swap them as you like. The Smart LUX is what it is — a white slab with a turbine LED.

The caveat with the Sync Energy, and it's worth naming, is Wi-Fi. User reports have been mixed, and the app platform migrated away from Monta, which unsettled early buyers. If the charger is going somewhere with a weak signal, specify the 4G variant at the outset. On the Indra side, 4G is a roughly £250 add-on, which effectively erases the Smart LUX's protection-rating advantage for anyone who needs cellular.

When neither of these is the right answer

If you're on Octopus Agile and want the charger to chase half-hourly prices through a proper supplier API, neither of these does that — the Ohme Home Pro at £535 is the cleaner choice. If solar is the centre of gravity and you want the most sophisticated diversion logic on the market, the myenergi Zappi GLO earns its £750. If you're a Tesla owner on Octopus Intelligent Go, Tesla's own API already does the scheduling and the Tesla Wall Connector becomes the default at £478.

The pairing we're actually comparing is narrower: you want a tethered smart charger, you don't need supplier-API cleverness, and you're deciding what to spend on build quality.

The verdict

Buy the Sync Energy Wall Charger 2 if:

• You want a smart tethered charger for the lowest sensible outlay
• The 7.5-metre cable solves a real parking geometry problem
• You're happy with IP65 and scheduled tariff charging

Buy the Indra Smart LUX if:

• Slim profile (78 mm) matters — narrow wall, visible location, a design-conscious installation
• You want IP67 weather-sealing and UK manufacturing behind the product
• The 6-metre cable reaches, or the 10-metre upgrade is acceptable

On a typical driveway, with a router within range and no particular design constraint, the Sync Energy Wall Charger 2 does the job for £253 less and frees the budget for a better install. If the wall is awkward, the weather is serious, or you want the better-made object, the Smart LUX earns the premium. Put on my wall, it would be the Sync Energy — and the saved £253 would go towards a tidier install.
