Wallbox Pulsar Max vs Indra Smart LUX: slim, tough, or compact?

The £79 that buys you weatherproofing and a tariff brain

Two compact chargers, two quite different philosophies. The Wallbox Pulsar Max at £536 is small, three-phase-capable, and leaves tariff scheduling to you. The Indra Smart LUX at £615 is slimmer still, weatherproofed to submersion, and talks to more than a thousand UK tariffs out of the box.

The shortest framing of the pair:

• Wallbox Pulsar Max — the compact generalist. Small footprint, 22kW option, manual on tariffs.
• Indra Smart LUX — the British-built specialist. Thinnest on the market, IP67, automatic on tariffs.

Does the Wallbox's three-phase option matter?

Only if your property has a three-phase supply, which most UK homes don't. When it does, the Wallbox Pulsar Max is the only charger in this pair that can give you 22kW — the Indra Smart LUX tops out at 7.4kW, single-phase only. That's not a flaw in the Indra; it reflects the market it was built for. But it does mean the decision is made for you if your consumer unit has three phases running into it.

For the other 95% of UK homes on single-phase, both deliver the same 7.4kW. At that point the price gap becomes a question about everything else.

Is the Indra's £79 premium worth it?

It depends on two things: your tariff and your wall.

On tariffs, the case is clear. The Wallbox Pulsar Max has scheduled charging and an app, but no direct supplier API. On Octopus Go with its fixed 12:30am–5:30am window, that's fine — set it and forget it. On Octopus Agile, where prices move every half hour and can hit 5p/kWh, the Wallbox cannot chase them. The Indra Smart LUX can, and claims coverage of over a thousand UK tariffs. Over a year of Agile charging, the £79 premium is usually recovered and then some.

On the wall, the case is physical. The LUX is 78mm deep — the thinnest tethered smart charger sold in the UK. Its IP67 rating means it survives immersion; the Wallbox's IP54 is splash-resistant and no more. If the charger lives under a porch, the Wallbox is fine. If it lives on an exposed wall facing the prevailing weather, the Indra is the more honest answer.

Two things push the other way. The Indra's standard warranty is three years against the Wallbox's five — a real gap, and the five-year Indra extension costs £100 more. And Indra's 4G module is about £250 extra; the Ohme Home Pro at £535 includes a SIM in the box. If your Wi-Fi is shaky at the driveway, that's a material cost.

Where the Ohme sits in this conversation

Worth naming the elephant. The Ohme Home Pro is £535 — a quid less than the Wallbox, £80 less than the Indra — and does the tariff automation that's the Indra's headline strength, with 4G included. It doesn't match the Indra's IP67 or the Wallbox's 22kW option. But for a single-phase home with average weather exposure where tariff intelligence is the main prize, it's the charger that makes both of these look specialised. If that's you, the Ohme vs Indra LUX comparison is the more useful page.

Which to buy

Buy the Wallbox Pulsar Max if:

• Your home has three-phase supply and you want 22kW
• Space on the wall is tight
• The five-year warranty matters more than tariff automation

Buy the Indra Smart LUX if:

• The charger will live fully exposed to weather
• You're on Octopus Agile or another half-hourly tariff
• British manufacturing and a 78mm profile both appeal

For the typical UK buyer — single-phase supply, sheltered installation, fixed off-peak tariff like Octopus Go or E.ON Next Drive — the Wallbox is the stronger buy at £536. You get a five-year warranty, a compact box, and the headroom of a 22kW option you may never use but haven't paid a fortune for. The Indra earns its £79 premium in two specific cases: exposed walls and variable tariffs. Honest answers for honest situations — just not the default.
