EO Mini Pro 3

The EO Mini Pro 3 is the smallest home EV charger on the UK market -- roughly the size of an A5 sheet of paper at just 215mm x 140mm x 100mm. If wall space is at a premium, you are installing in a narrow garage, or you simply do not want a large box on the side of your house, this is your best option. Despite its remarkably compact size, it packs in solar diversion with a CT clamp included as standard, smart tariff presets for Octopus Go and EDF GoElectric, and Ethernet connectivity alongside Wi-Fi and Bluetooth -- making it the only charger here with a wired internet connection option. The EO Mini Pro 3 is also sold through British Gas under the Hive brand, which offers a Power+ feature that credits back 25% of your EV charging costs to your energy account. At 2.5 kg it is the second lightest charger on this list (after the Easee One at 1.5 kg), which further simplifies installation in awkward positions. It is not the cheapest or the smartest charger available, but it is definitively the smallest -- and for some installations, that is the only thing that matters.

Best for: Installations where space is extremely limited, or homeowners who want the smallest possible wall-mounted charger without sacrificing solar diversion and smart tariff scheduling.

Installation

The EO Mini Pro 3 is purpose-built for constrained installations. At 215mm x 140mm x 100mm and just 2.5 kg, it can fit in spaces where no other charger will. This makes it ideal for narrow garage walls, recessed mounting between pipes or cables, or positions where a larger unit would obstruct a pathway or doorway. The standard 5-metre tethered cable is adequate for most setups, and the charger is also available in an untethered version if you prefer a socket-only installation. The included CT clamp for solar diversion is fitted to your meter tails during installation, which is standard practice and does not add significant time or cost. A unique installation advantage is the Ethernet port -- if your charger location is near a network point or you can run a cable, a wired connection is more reliable than Wi-Fi, particularly in garages with thick walls or metal doors that attenuate wireless signals. An optional 4G module is available for locations where neither Wi-Fi nor Ethernet is practical. The charger is IP54 rated, suitable for sheltered outdoor positions. See our complete installation guide for what to expect.

Tariff Compatibility

The EO Mini Pro 3 includes smart tariff presets in the EO app for Octopus Go, EDF GoElectric, and other common time-of-use tariffs. These presets automatically configure the correct off-peak charging windows for your tariff, saving you from manual setup. However, like most chargers other than the Ohme, it does not have direct API integration with energy providers. It cannot request extended off-peak slots on Octopus Intelligent Go or dynamically optimise for half-hourly pricing on Agile Octopus. The British Gas/Hive integration is a notable alternative: if you are a British Gas customer on their EV Power+ tariff, the Hive-branded version of this charger credits back 25% of your EV charging costs. This is not a tariff in the traditional sense but an effective discount on your overall charging bill. For drivers who are already in the British Gas ecosystem, this makes the EO Mini Pro 3 a financially compelling option. See our best EV charging tariff guide for a full comparison.

Price Breakdown

At £699, the EO Mini Pro 3 is the same price as the Wallbox Pulsar Max and close to the Hypervolt Home 3 Pro (£690). For this money, you get the smallest form factor on the market, a CT clamp for solar diversion included as standard, and Ethernet connectivity. The price is harder to justify if space is not a constraint, as the Hypervolt offers more features for £9 less. However, if the EO's compact dimensions are what makes your installation possible, the price becomes secondary. The British Gas Power+ 25% cashback can also offset the cost over time. For eligible properties, the OZEV grant brings the installed cost below £1,000.

How It Compares

The EO Mini Pro 3's most natural comparison is with the Zappi GLO on solar diversion. See our Zappi GLO vs EO Mini Pro 3 comparison for a breakdown of the Zappi's superior Eco/Eco+ modes versus the EO's included CT clamp and compact size. If your decision is between the two most compact chargers on the market, the Wallbox Pulsar Max (198mm x 201mm x 99mm) is slightly smaller in two dimensions but taller, while the EO is shorter overall -- the right choice depends on your specific wall space. For the same price, the Hypervolt Home 3 Pro offers a wider feature set including better build quality (IP66 vs IP54) and cable length options up to 10 metres. The EO wins when size is the deciding factor; for everything else, the Hypervolt or Zappi are stronger choices.
