EO Mini Pro 3 vs Indra Smart LUX: Compact Chargers Compared

Two Tiny Chargers, Two Different Takes on "Compact"

Both the EO Mini Pro 3 and the Indra Smart LUX market themselves on size. They're among the smallest home EV chargers you can buy in the UK. But "small" means different things here, and once you look past the physical dimensions, these are quite different products with different strengths.

In a nutshell:

• EO Mini Pro 3: The smallest charger on the market — nothing else comes close to its A5-sized footprint. Good smart features, solar diversion included, and a British Gas cashback perk.
• Indra Smart LUX: The slimmest tethered charger at 78mm deep, with class-leading durability (IP67 + IK10) and the widest smart tariff support of any home charger.

What Does "Smallest" Actually Mean for Your Wall?

The EO Mini Pro 3 measures 215mm × 140mm × 100mm and weighs just 2.5 kg. It is, by any measure, tiny — about the size of a hardback book. If you're mounting a charger in a narrow passageway, inside a tight garage, or anywhere space is genuinely at a premium, nothing else on the market competes.

The Indra Smart LUX takes a different approach. Its footprint is larger at 201mm × 306mm, but it's only 78mm deep. That razor-thin profile means it barely protrudes from the wall. For most driveways and garages, this matters more than the overall footprint — a charger that sticks out 78mm versus 100mm is noticeably less obtrusive. At 3.6 kg it's heavier, but still light by charger standards.

So: if you need the smallest possible box, the EO wins. If you want the flattest possible profile against a wall, the Indra wins. Different problems, different solutions.

Is the Indra Smart LUX Worth £65 More Than the EO Mini Pro 3?

At £615 for the 10m cable version versus £550 for the EO, the price gap is modest. But the Indra earns that premium several times over.

Start with durability. The Indra's IP67 rating means it can survive temporary submersion — the EO's IP54 is merely splashproof. Add IK10 impact resistance and you've got the toughest home charger on the market. If your charger is wall-mounted near a driveway where it might take a knock, or in an exposed coastal location, the Indra is built for it.

Then there's the cable. The Indra ships with 6 metres as standard (10m available), while the EO gives you 5 metres. That extra metre matters more than you'd think — it's often the difference between reaching the charge port comfortably and stretching the cable tight across your bumper.

On power, the Indra delivers 7.4kW versus the EO's 7.2kW. The real-world difference is negligible for overnight charging, but if you're topping up during a short window on a smart tariff, every fraction helps.

The Indra also includes built-in SPD and PEN fault detection, which can simplify installation and potentially reduce your installer's costs. The EO doesn't mention these, so your electrician may need to add them separately.

Smart Tariff Support: The Indra's Quiet Advantage

Both chargers support scheduled charging and smart tariff presets, but the scope is vastly different. The EO Mini Pro 3 offers presets for Octopus Go, EDF Go Electric, and a handful of others. Functional, but limited.

The Indra Smart LUX integrates with over 1,000 UK energy tariffs, including Octopus Agile's half-hourly variable pricing. That's a different league entirely. If you're on Agile or planning to switch, the Indra can chase the cheapest 30-minute slots automatically — something the EO simply can't match. For a deeper look at tariff options, see our EV tariff comparison.

The EO does have one unique trick: British Gas Power+ integration through the Hive ecosystem, which credits back 25% of charging costs. That's a meaningful saving if you're already a British Gas customer with Hive. But it locks you into one provider's ecosystem, whereas the Indra's broad tariff support keeps your options open.

Solar Diversion: Both Capable, Neither Best-in-Class

Both chargers include a CT clamp for solar PV surplus diversion as standard, which is welcome — some competitors charge extra for this. Neither is as refined as dedicated solar-first chargers, but for most households with panels, both will do a reasonable job of using excess generation.

Which Should You Buy?

Buy the EO Mini Pro 3 if:

• You have a genuinely tight installation space where every millimetre counts
• You're a British Gas/Hive customer who'll benefit from the 25% Power+ cashback
• You want Ethernet connectivity as standard for the most reliable connection
• Budget is tight and £65 matters

Buy the Indra Smart LUX if:

• You want the best-protected charger on the market (IP67 + IK10)
• You're on or considering Octopus Agile or another variable tariff
• You want a longer cable (6m standard, 10m available)
• You prefer buying UK-manufactured kit (made in Worcestershire)

For most buyers, the Indra Smart LUX is the better charger. It's tougher, smarter with tariffs, and delivers 7.4kW at full rate. The £65 premium is easy to justify. But the EO Mini Pro 3 has a genuine role for space-constrained installations and British Gas households — and at that size, it's in a category of one.
