GivEnergy EV Charger vs Zaptec Go 2: battery or future-proofing?

Two specialists, £22 apart

These are not rivals in the usual sense. The GivEnergy EV Charger at £478 and the Zaptec Go 2 at £500 are built around two entirely different bets — one about the energy you already store, one about the energy the car might one day give back.

• GivEnergy EV Charger — the charger that pulls from your home battery, not just your solar panels.
• Zaptec Go 2 — the only AC home charger in the UK certified V2G-ready, with MID-metered billing and free 4G built in.

Buy the wrong one for your situation and you're paying for a feature you'll never use. Get it right and the £22 between them is the least interesting number on the page.

What the GivEnergy actually does that others don't

Most "solar-aware" chargers — the Zappi GLO, the EcoFlow PowerPulse 2 — divert live solar generation to the car. Useful in July, largely theoretical in January. The GivEnergy goes further: it can draw from a home battery, including compatible third-party units, not only GivEnergy's own. That means electricity you bought at 7p on Octopus Intelligent Go overnight, stored in the battery, can later be pushed into the car during the day without re-importing at peak rates.

This is a narrow use case, but a real one. If you already run a home battery and the geometry of your day means the car is away overnight and home in the afternoon, no other charger at this price solves the problem. Without a battery, though, the argument collapses. The app is basic next to the Ohme Home Pro, the tariff integration is schedule-based only, and the Easee One is £73 cheaper for the same everyday charging job.

What the Zaptec is actually buying you today

V2G — vehicle-to-grid, where the car sells electricity back to the grid at peak times — is the headline on the Go 2, and it's the feature you cannot use yet in any meaningful sense. The Indra Smart PRO sits in a similar space. Treat V2G as a bonus that may or may not arrive before the charger's five-year warranty expires.

What the Go 2 does today, though, is quietly sensible. The MID-approved energy meter gives legally certified readings — useful if you're claiming mileage reimbursement from an employer, or splitting costs on a rental. The 4G connection is subscription-free, so Wi-Fi dropouts don't take the charger offline. It auto-switches between single-phase (7.4kW) and three-phase (22kW), though as with any 22kW unit, single-phase homes — the vast majority — will never see the higher figure. OCPP 1.6J compliance means it plugs into third-party energy platforms if you want to escape the maker's own app, which is basic.

It's also untethered only. If you want a cable permanently hanging from the wall, the GivEnergy's 5-metre tether wins by default.

Where neither is the right answer

Both chargers leave tariff automation to you. Neither has a live supplier API the way the Ohme Home Pro does on Octopus Agile. If you're on Agile and want something chasing half-hourly rates without you touching the app, neither of these is built for that job.

Similarly, a pure solar household without a battery is better served by the Zappi GLO — the GivEnergy's solar divert is fine, but the whole GivEnergy argument is battery drawdown. Without a battery, you're paying for machinery you can't drive. See the Zappi GLO vs GivEnergy comparison if solar is your actual question.

The verdict

Buy the GivEnergy EV Charger if:

• You own or are installing a home battery (GivEnergy or compatible)
• You want a tethered charger with a 5-metre cable at £478
• Whole-home energy monitoring through one portal matters to you

Buy the Zaptec Go 2 if:

• You intend to use V2G when it arrives, and are willing to pay £500 to be ready
• You need MID-certified meter readings for reimbursement or billing
• A five-year warranty and subscription-free 4G matter more than a tethered cable

On a wall today, for a typical household, neither would be our pick — the Easee One at £405 or the Ohme Home Pro at £535 cover most buyers better. But if you already run a home battery, the GivEnergy is the one charger at this price that uses it properly. That's a small audience with a clear answer.
