Wallbox Pulsar Max vs Zaptec Go 2: compact box or a bet on V2G?

The £36 that buys you a different philosophy

Two chargers, similar money, different bets. The Wallbox Pulsar Max at £536 is the compact, tethered default — small enough to fit where rivals won't, with a 5-metre cable already attached. The Zaptec Go 2 at £500 is untethered, lighter, and ships with free 4G, an MID-approved energy meter and the only V2G-ready certification on a UK AC home charger.

The shortest version:

• Wallbox Pulsar Max — tethered, tiny, three-phase capable. The charger for a tight wall and a buyer who doesn't want to think about cables.
• Zaptec Go 2 — untethered, 4G built in, hardware ready for a V2G future that hasn't fully arrived. The charger for the patient.

Is the Wallbox's £36 premium worth it?

It buys you two things worth having and one thing worth questioning.

Worth having: the tethered cable and the footprint. At 198×201mm the Pulsar Max is one of the smallest proper home chargers sold in the UK, and the cable stays with the wall, which most people prefer after the novelty of fetching a portable Type 2 wears off. Power Boost — the dynamic load balancer that throttles the car rather than tripping your main fuse — is a quiet win on older single-phase supplies.

Worth questioning: what the Pulsar Max doesn't give you at £536. No 4G, so if your Wi-Fi drops at the end of the garden, so does your scheduling. No cellular fallback at all — Wi-Fi and Bluetooth only. Solar integration needs the separate Wallbox Power Meter, bought extra. And the app, like the Zaptec's, doesn't talk directly to your tariff.

Against that, the Zaptec Go 2 at £500 includes subscription-free 4G, an MID-approved meter that gives legally certified kWh readings (useful if you're claiming back business mileage or charging a tenant), OCPP 1.6J for third-party energy management, and the V2G-ready certification. The meter alone is a feature no other charger at this price offers.

When the Zaptec's V2G claim actually matters

Be honest with yourself. V2G in the UK is still a patchwork: a handful of compatible cars, one or two approved tariffs, and a grid connection process that moves slowly. The Zaptec Go 2's certification is real, but the ecosystem around it is not yet rich enough to justify the purchase on that basis alone. You're buying a hardware option on the future.

That said, the Go 2 earns its £500 today even if V2G never arrives. The MID meter, the free 4G, the auto-switching between single- and three-phase up to 22kW — these are features people use from day one. The V2G is upside. If you want V2G you can actually use now, the Indra Smart PRO has been doing it longer, and the dedicated comparison is the better page for that question.

Neither is a smart-tariff charger

Both lean on manual scheduling through their own apps. On a fixed-window tariff like Octopus Go (8.5p between 00:30 and 05:30) or E.ON Next Drive (7.5p between midnight and 06:00), that's fine — set the window once and forget. On Octopus Agile, where 30-minute rates can swing from 5p to 30p overnight, neither charger chases the price.

If your tariff is variable, the £535 Ohme Home Pro is the better answer — it talks directly to Octopus and shifts the car to the cheapest half-hours automatically. The Ohme vs Wallbox and Ohme vs Zaptec pages compare both directly.

The verdict

Buy the Wallbox Pulsar Max if:

• Your install spot is tight and you need the smallest possible footprint
• You want a tethered cable and don't want to think about it
• Three-phase is on the table and you prefer a mature installer network

Buy the Zaptec Go 2 if:

• V2G matters to you, even as a five-year bet
• You want free 4G, an MID-approved meter and OCPP as standard
• You're happy with untethered and already own a decent Type 2 cable

On a typical single-phase UK wall, the Zaptec Go 2 is the more interesting box for £36 less. The MID meter and subscription-free 4G are real features, not brochure lines, and the V2G certification costs you nothing even if it never comes good. The Wallbox Pulsar Max is the right answer for one specific buyer — the one with a narrow wall and a strong preference for tethered — and that buyer knows who they are. Everyone else: the Zaptec.
