Two Tiny Chargers, One Big Decision
If you've landed on this page, you probably have limited wall space — or you simply don't want a chunky box ruining the look of your driveway. The Wallbox Pulsar Max and EO Mini Pro 3 are the two most compact home EV chargers you can buy in the UK right now, and they both make a strong case for themselves.
But "small" is where the similarities largely end. These two chargers differ meaningfully on price, power, warranty, and smart features — enough that the right pick depends entirely on your priorities.
In a nutshell:
- Wallbox Pulsar Max (£496): Better value, longer warranty, three-phase option, more colour choices
- EO Mini Pro 3 (£550): Even smaller footprint, solar diversion included out of the box, Ethernet connectivity
Is the EO Mini Pro 3 Really That Much Smaller?
Both chargers market themselves as compact, but the EO Mini Pro 3 takes it to another level. At 215mm × 140mm, its face is roughly the size of a paperback novel. It weighs 2.5 kg — light enough that your installer could hold it in place with one hand while drilling with the other.
The Pulsar Max is no giant either. At 198mm × 201mm it's essentially a square, and its IK10 impact rating means it can take a knock from a wayward football or bike handlebar without complaint. The EO doesn't carry that impact rating, so if your charger is going somewhere it might get bumped — a narrow garage, a spot near bins — the Wallbox is the safer bet despite being marginally larger.
For truly constrained spaces where every centimetre counts — think a pillar between two parking bays, or a cramped utility cupboard wall — the EO wins on pure dimensions. Everywhere else, the size difference is academic.
Solar Diversion: The EO Mini Pro 3's Hidden Advantage
Here's something that caught my eye. The EO Mini Pro 3 includes a CT clamp as standard for solar diversion. Plug it in, clip the sensor to your meter tails, and it'll route surplus solar generation into your car. No extra hardware to buy.
The Wallbox Pulsar Max offers solar integration too, through its Eco-Smart feature, but you'll need to purchase a separate Wallbox Power Meter. That's an additional cost that chips away at the Pulsar Max's £54 price advantage.
That said, if you're serious about maximising solar self-consumption, neither of these chargers matches a dedicated solar charger like those covered in our best EV charger for solar panels guide. But for casual solar diversion — using whatever's spare rather than exporting it — the EO's included CT clamp is a genuine convenience.
£496 vs £550: Does the Wallbox Pulsar Max Justify Being Cheaper?
It doesn't just justify it — it arguably overdelivers. For £54 less than the EO Mini Pro 3, the Pulsar Max gives you a 5-year warranty (versus 3 years), 7.4kW output (versus 7.2kW), dynamic load balancing via Power Boost, voice control through Alexa and Google, and six colour options.
The EO counters with Ethernet connectivity — a real plus if your Wi-Fi doesn't reach the charger location — and optional 4G for properties with no broadband at the charging point. It also offers smart tariff presets for Octopus Go, EDF Go Electric, and others, plus a British Gas/Hive Power+ feature that credits back 25% of charging costs if you're in that ecosystem.
The Pulsar Max lacks native smart tariff integration, which is a miss. You can still schedule charging via the myWallbox app to hit off-peak windows manually, but it won't dynamically optimise against variable rates like Octopus Agile. If automated tariff optimisation matters to you, have a look at our EV tariff comparison and consider whether a charger like the Ohme might be a better fit altogether.
For most buyers not locked into the Hive ecosystem, the Pulsar Max's combination of lower price, longer warranty, and broader feature set makes it the stronger proposition. The three-phase capability is a future-proofing bonus too — irrelevant for most homes today, but handy if your electrical setup ever changes.
Which Should You Buy?
Buy the Wallbox Pulsar Max if:
- You want the best overall value from a compact charger
- A 5-year warranty matters to you
- You'd like voice control or the option to choose a colour that suits your home
- You want three-phase readiness for the future
Buy the EO Mini Pro 3 if:
- You have an extremely tight installation space and need the smallest possible unit
- You have solar panels and want diversion without buying extra hardware
- Your Wi-Fi is unreliable at the charger location (Ethernet and optional 4G solve this)
- You're a British Gas/Hive customer who can benefit from the 25% Power+ cashback
For the majority of Tesla owners looking for a discreet, well-featured home charger, the Wallbox Pulsar Max is the better buy. It's cheaper, warrantied for longer, and doesn't ask you to compromise on anything that matters day-to-day. The EO Mini Pro 3 earns its place for buyers with specific needs — extreme space constraints, solar panels, or poor connectivity — but at £550 with a shorter warranty, it needs those circumstances to justify the premium.
