GivEnergy EV Charger vs EO Mini Pro 3

A niche charger versus a small one

These two share a price bracket — £444 for the GivEnergy EV Charger, £523 for the EO Mini Pro 3 — but almost nothing else. The GivEnergy exists to serve homes with battery storage. The EO exists to fit on walls where a standard charger won't. If neither description matches your situation, both become hard to recommend against the wider field.

• GivEnergy EV Charger — £444. The one to buy if you have a home battery and want to push stored overnight electricity into the car.
• EO Mini Pro 3 — £523. The one to buy if your mounting wall is too narrow, too recessed, or too exposed for a full-size unit.

The GivEnergy's one trick — and why it matters

Battery-to-EV charging is the GivEnergy's entire argument. Most chargers with solar divert can only use electricity the panels are producing right now. The GivEnergy can also draw from a home battery — GivEnergy's own or a compatible third-party unit — meaning you can fill the battery at 8p/kWh on Octopus Go overnight, then drip that stored energy into the car whenever suits you. For a household already inside the GivEnergy ecosystem, the monitoring portal ties solar generation, battery state, and EV charging into a single view.

Strip the battery away and the picture changes. The app is basic next to an Ohme Home Pro or Hypervolt Home 3 Pro. There is no live tariff API — just manual scheduling. The 5-metre cable and 7kW output are adequate but unremarkable. At £444 it is not expensive, but the VCHRGD Seven Pro at £430 packs sharper software, and the Rolec EVO at £356 undercuts it by £88 with a five-year warranty. The GivEnergy is a specialist — effective in the right setup, ordinary everywhere else.

The EO's size advantage is real but narrow

The EO Mini Pro 3 measures 215 × 140 × 100 mm. That is roughly A5 paper, 2.5 kg on the wall. No other mainstream UK charger comes close. If you are mounting beside a doorframe in a narrow side-return, or recessing into a garage alcove where a 320 mm unit won't clear the wing mirror, the EO may be the only option that physically fits.

It also earns a mention for connectivity. Wi-Fi, Bluetooth, and an Ethernet port are all built in, with optional 4G for signal-dead garages. That wired fallback is useful — Wi-Fi dropouts are the most common complaint across every charger brand, and Ethernet removes the variable entirely.

The catch is the software transition. EO is retiring its own app and migrating users to ev.energy. The platform you buy into is not the one on the older marketing material. ev.energy handles scheduling for fixed-window tariffs like Octopus Go or EDF GoElectric competently enough, but it does not match the Ohme's half-hourly optimisation on Octopus Agile. At £523, the EO is £79 more than the GivEnergy and only £16 cheaper than the Ohme Home Pro at £539 — which has a direct supplier API and genuinely dynamic tariff support. That is a thin margin for a less capable app.

One exception: British Gas customers on the Hive Power+ tariff get 25% of charging costs credited back through the EO's Hive integration. That structural discount is locked to the British Gas ecosystem, but for those inside it, the maths shifts meaningfully in the EO's favour.

Is the £79 gap justified?

Not on features alone. The GivEnergy is cheaper and does something distinctive — battery-to-EV — that the EO cannot. The EO is smaller and better-connected (Ethernet, optional 4G) but otherwise a schedule-based charger in a market where £539 buys you the Ohme Home Pro's live tariff intelligence.

The £79 is justified only by physical constraint or by British Gas loyalty. If your wall demands the smallest possible unit, the EO earns its place. If Hive Power+ is your tariff, the 25% cashback makes the EO structurally cheaper to run than anything else in this bracket. Outside those two scenarios, the premium buys you a middling charger at a price uncomfortably close to better ones.

Both chargers carry three-year warranties, both are OZEV-approved for the £500 grant (renters and flat owners), and both have 5-metre tethered cables. Neither stands out on durability — the GivEnergy's IP65 rating edges the EO's IP54, which matters if the unit faces open weather rather than a sheltered wall.

The verdict

Buy the GivEnergy EV Charger if:

• You have a home battery — GivEnergy or compatible — and want battery-to-EV charging
• You are already in the GivEnergy monitoring ecosystem
• You want the cheaper unit and do not need dynamic tariff support

Buy the EO Mini Pro 3 if:

• Your mounting space is too tight for a standard-sized charger
• You are on British Gas Hive Power+ and want the 25% cashback
• You need Ethernet or 4G as a wired fallback in a poor-signal location

For most buyers landing on this page without a home battery or a tight wall, neither charger is the strongest pick. The Ohme Home Pro at £539 does more with your tariff. The Tesla Wall Connector at £475 gives Tesla owners native integration and a longer cable. If budget is the priority, the Rolec EVO at £356 is hard to argue with. The GivEnergy and EO each solve a specific problem well — but you need to have that problem first.
