Hypervolt Home 3 Pro vs EO Mini Pro 3: size or substance?

The £140 between small and sturdy

These two are sold on completely different promises. The EO Mini Pro 3 at £550 is the smallest mainstream charger you can fit on a UK wall — A5-sized, 2.5kg, designed to disappear. The Hypervolt Home 3 Pro at £690 goes the other way: IP66 and IK10, a 10-metre cable option, a proper phone line in the UK when something breaks.

Each charger's job, plainly:

• EO Mini Pro 3 — the charger that fits where others won't. Compact, competent, unremarkable otherwise.
• Hypervolt Home 3 Pro — the all-rounder. Second-best at most things, rarely wrong.

When the EO's size is the whole argument

Physical dimensions decide a lot of charger purchases and get written about far too little. The EO Mini Pro 3 measures 215 × 140 × 100mm. The Hypervolt Home 3 Pro measures 270 × 170 × 110mm and weighs nearly twice as much. If you're mounting next to a doorway, inside a narrow porch, or on a pillar that won't accept something the size of a hardback novel, the EO is often the only charger on the shortlist.

Outside that scenario, the EO's case is weaker. 7.2kW against the Hypervolt's 7.4kW is a rounding error — maybe ten minutes a night on a full top-up. The Ethernet port is a genuine point of difference for sheds and outbuildings where Wi-Fi drops, and the optional 4G module solves the edge cases Ethernet can't reach. Useful, but niche.

When the Hypervolt earns its £140

The Hypervolt Home 3 Pro has three things the EO Mini Pro 3 doesn't. First, the 10-metre tethered cable option — the longest on any charger on this site. If your parking spot isn't directly beneath the wall, this alone decides the purchase. The EO's 5-metre cable is fixed.

Second, IP66 + IK10 against the EO's IP54. Both are rated for outdoor use; only one is rated for a football or a reversing trailer hitch. For an exposed wall facing open weather, the Hypervolt is the less anxious choice over a decade.

Third, the warranty extends to five years for £100, and UK phone support actually answers. That matters more than any spec sheet suggests, and it matters more with age.

On tariffs, both chargers handle the staples. Octopus Go and EDF GoElectric work fine as schedule presets on either. Neither matches the Ohme Home Pro for half-hourly automation on Octopus Agile — if your tariff changes rates every thirty minutes, that's a different comparison, and the Ohme vs Hypervolt write-up covers it properly.

The British Gas exception

One sharp detail on the EO side: the Hive Power+ variant of the EO Mini Pro 3 credits 25% of charging costs back on British Gas's EV Power+ tariff. If your supplier is already British Gas and you intend to stay, that's a structural discount no other charger in this comparison can match. It doesn't make the EO better than the Hypervolt in absolute terms — it makes it cheaper to run inside one specific ecosystem. Worth checking the maths before defaulting to the Hypervolt.

Solar, briefly

Both include a CT clamp and both do basic surplus diversion. Neither does it well. If you have meaningful solar generation and want a charger that follows the sun through the day, the Zappi GLO is the right answer and both of these are compromises. The Zappi vs EO and Zappi vs Hypervolt pages take that decision apart properly.

Which to buy

Buy the Hypervolt Home 3 Pro if:

• The parking spot is more than five metres from the wall
• The charger will face weather with no shelter
• You want UK support when something goes wrong

Buy the EO Mini Pro 3 if:

• The mounting location is tight
• British Gas is your supplier and the Hive Power+ cashback applies
• You need a wired Ethernet or 4G connection rather than Wi-Fi

For most buyers choosing between these two, the Hypervolt is the charger that goes on the wall. £140 is real money, but the 10-metre cable option, the IP66 build, and the support line are the kind of things you notice in year three rather than week one. The EO wins specific arguments — size, Hive, Ethernet — and loses the general one. If none of its specifics apply to you, the Hypervolt is the safer cheque to write. If you're price-sensitive in that broader sense, the Tesla Wall Connector at £478 is the more honest comparison.
