Hypervolt Home 3 Pro vs EO Mini Pro 3: All-Rounder vs Ultra-Compact

The All-Rounder vs the Smallest Charger on the Market

These two chargers sit within £9 of each other, both offer solar diversion with a CT clamp included, and both support smart tariff scheduling. On paper, they look like near-identical propositions. In practice, they could hardly be more different.

The Hypervolt Home 3 Pro is a UK-manufactured charger that has earned a reputation as the do-everything option — strong build quality, solid solar integration, smart tariff support, and a polished app experience. The EO Mini Pro 3, meanwhile, has staked its claim on a single, genuinely impressive feat: it is the smallest home EV charger you can buy, roughly the size of an A5 sheet of paper. If you have a tight installation spot — a narrow garage wall, a pillar, or a shared parking area — the EO might be your only realistic option.

So the real question isn't which is "better" in the abstract. It's whether the EO's compact form factor matters enough to you to trade away some of the Hypervolt's advantages in build toughness, cable choice, and overall polish.

In a nutshell:

• Hypervolt Home 3 Pro (£690): The best all-rounder — strong across smart tariffs, solar, build quality, and support, with nothing to apologise for.
• EO Mini Pro 3 (£699): The smallest charger on the market, ideal for space-constrained installations, with competent smart features and a useful British Gas cashback option.

Spec Comparison

Power and Charging Speed

The difference between 7.4kW and 7.2kW is, frankly, marginal. On a typical 60kWh Tesla battery charged from 20% to 80%, the Hypervolt would finish roughly 10–15 minutes sooner — barely noticeable over an overnight session. Both chargers will add approximately 25 miles of range per hour, which is more than enough to replenish the average UK daily drive of around 20 miles in well under an hour.

Where the Hypervolt does pull ahead is cable length flexibility. You can specify 5m, 7.5m, or 10m cables, which matters more than people realise — if your consumer unit is at the front of the house and your parking is at the side, a 5m cable simply won't reach. The EO Mini Pro 3 comes with a fixed 5m cable, so you'll need to factor in potential additional wiring costs if your parking spot is further away. That said, the EO does offer an untethered (socketed) option, which is unusual at this price point and handy if you own multiple EVs with different cable preferences.

Smart Tariff Integration

Both chargers support scheduled charging to take advantage of cheap overnight electricity — the feature that saves most UK EV drivers the most money. On a tariff like Octopus Go (7.5p/kWh between 00:30 and 04:30), charging a Tesla Model 3 from 20% to 80% costs roughly £2.70 instead of £10+ at standard daytime rates. Over a year of average UK mileage (~7,400 miles), that's a saving of around £400–500 compared to peak-rate charging.

The EO Mini Pro 3 offers named tariff presets — Octopus Go, EDF Go Electric, and others — which simplifies setup. It also has a notable trick up its sleeve: the British Gas/Hive Power+ integration, which credits back 25% of your charging costs. If you're already in the Hive ecosystem, that's a genuine money-saver, though it does lock you into British Gas as your energy supplier. The Hypervolt takes a more universal approach with app-based tariff integration, and as viablepower.co.uk notes, it handles scheduling and energy monitoring through its own well-designed app.

Neither charger matches the Ohme Home Pro's direct API integration with Octopus Intelligent Go (which can unlock extra off-peak hours), but both are perfectly capable of exploiting time-of-use tariffs for significant savings.

Solar Diversion

Both chargers include a CT clamp as standard for solar diversion — no extra hardware to buy, which is a welcome touch at this price point. The idea is simple: the CT clamp monitors your solar generation and diverts surplus energy to your car rather than exporting it to the grid at a measly 4–5p/kWh.

As heatable.co.uk highlights in their review, the Hypervolt Home 3 Pro offers three solar charging modes — Boost, Eco, and Super Eco — giving you granular control over how aggressively it prioritises solar energy. Super Eco mode will only charge from surplus solar, while Eco blends solar with a small grid top-up to maintain a minimum charge rate. It's a practical, well-thought-out system.

The EO Mini Pro 3 also supports solar diversion via its CT clamp, though the implementation is less feature-rich. Both chargers fall short of the myenergi Zappi's more sophisticated Eco/Eco+ modes, but for most households with a typical 3–4kW solar array, either will do a solid job of maximising self-consumption during sunny months. As topcharger.co.uk notes, the Hypervolt's solar integration is a genuine strength of the unit.

Build Quality and Design

This is where the gap between the two chargers is most stark. The Hypervolt Home 3 Pro carries an IP66 + IK10 rating — IP66 means it's fully protected against dust and powerful water jets, while IK10 means it can withstand 20 joules of impact (roughly equivalent to a 5kg weight dropped from 40cm). As electriccarguide.co.uk puts it, it's "pretty hard to damage." Add interchangeable colour covers (Ultra White, Space Grey, Ultra Black) and you have a charger that's both tough and attractive.

The EO Mini Pro 3 carries an IP54 rating — adequate for sheltered outdoor use, but noticeably less robust. IP54 protects against splashing water from any direction, but not the sustained jets or heavy rain that IP66 handles. If your charger will be fully exposed to the elements on a driveway with no overhead cover, the Hypervolt is the safer bet. If it's tucked inside a garage or under a carport, IP54 is perfectly fine.

On the connectivity front, the EO does have one advantage: Ethernet. A wired connection is more reliable than Wi-Fi, particularly in garages or outbuildings where your router signal might struggle. The optional 4G add-on is also useful for detached garages or rural properties with patchy broadband.

Price and Value

At virtually identical prices, this comes down to what you value. The Hypervolt gives you superior weatherproofing, cable length options, interchangeable covers, and an extendable warranty (5 years for an extra £100). The EO gives you the smallest possible footprint, Ethernet connectivity, and the British Gas Power+ cashback if you're on their tariff. Pound for pound, the Hypervolt offers more — unless physical size is your primary constraint.

Who Should Buy Which?

Buy the Hypervolt Home 3 Pro if:

• You want the best all-round package of features, build quality, and support at this price
• Your charger will be exposed to the elements and you want IP66 + IK10 toughness
• You need a longer cable (7.5m or 10m) for your parking setup
• You want the option to extend your warranty to 5 years
• You value UK manufacturing and responsive customer support (5-second average call response)

Buy the EO Mini Pro 3 if:

• You have a genuinely tight installation space where the Hypervolt won't fit
• You want Ethernet connectivity for a rock-solid connection in a garage or outbuilding
• You're a British Gas customer and can benefit from the Hive Power+ 25% cashback
• You prefer an untethered (socketed) option for multi-vehicle flexibility
• You need optional 4G for a location with poor Wi-Fi coverage

Our recommendation: For most UK homeowners, the Hypervolt Home 3 Pro is the better buy. It's £9 cheaper, tougher, more flexible on cable length, and scores higher across every review we've seen — earning a 4.7/5 rating and consistent praise from wepoweryourcar.com and others. The EO Mini Pro 3 is a genuinely clever product, but its advantages are situational. If you need the smallest possible charger or you're locked into the British Gas ecosystem, it's a solid choice. For everyone else, the Hypervolt is the one to have.
