Wallbox Pulsar Max vs Wallbox Quasar 2

> V2G boundary: A “V2G-ready” label or ISO 15118 support does not by itself provide bidirectional power conversion, export approval or a live energy service. Confirm the compatible car, genuinely bidirectional hardware, certified complete system, installer, service and network approval before assigning value to the claim. Read the UK V2G explainer.

A £5,587 gap — and what sits inside it

Same brand, same app, same logo on the box. That is roughly where the similarities end. The Wallbox Pulsar Max is a £513 AC wallbox that charges your car. The Wallbox Quasar 2 is a £6,100 bidirectional DC unit that charges your car and — with the right vehicle — sends power back into your house or the grid. The price gap is £5,587. The question is whether the technology inside that gap is worth buying today or worth waiting out.

• Pulsar Max — a compact, proven AC charger. 7.4 kW single-phase, five-year warranty, OZEV-approved. Does one thing well.
• Quasar 2 — a bidirectional DC charger on a UK waiting list. Up to 12.8 kW in both directions, CCS2 connector, three-year warranty, not OZEV-approved. Does something new, for a price.

What the Quasar 2 actually promises

Bidirectional charging means your car's battery becomes a home battery. During a power cut, the Quasar 2 can run your house from the car. During peak-rate hours, it can discharge the car and save you the spread between off-peak and peak electricity. On a V2G tariff, it can export to the grid and earn revenue.

The catch — and it is a large one — is that the compatible car list is short. The Kia EV9 is the headline model. Most UK Teslas, most VW Group cars, most Stellantis vehicles cannot do DC bidirectional today. If your car is not on the list, the Quasar 2 is a £6,100 paperweight that charges at 12.8 kW via CCS2 — functional, but absurdly overpriced for one-way charging.

Installation compounds the cost. The Quasar 2 needs a specialist installer, a DNO G99 application with a 30-to-60-working-day lead time, and an installed total likely north of £7,600. The Pulsar Max needs a standard electrician, a morning's work, and £400–£600 on top of the unit price.

The Pulsar Max as the sensible Wallbox

At £513, the Pulsar Max sits in the middle of the UK charger market. It is the smallest unit in our catalogue at 198 × 201 × 99 mm and 4.2 kg — useful if your mounting wall is tight or shared. The five-year warranty beats the Quasar 2's three years, which feels pointed given the price difference.

Its weaknesses are familiar. The 5-metre cable has no longer option. IP54 is the joint-lowest weather rating alongside the Tesla Wall Connector. There is no native tariff integration beyond Intelligent Octopus Go — on Octopus Agile, you are setting schedules manually where an Ohme Home Pro would chase half-hourly prices for you. Solar integration requires a separate Wallbox Power Meter. None of these are disqualifying, but they do mean the Pulsar Max earns its place on size and build rather than software. Readers weighing it against similarly priced AC chargers will find more detail in the Pulsar Max vs Easee One comparison.

Eligible renters and flat owners can claim the £500 OZEV grant against the Pulsar Max, which covers almost the entire unit price and contributes to install costs. The Quasar 2 is not OZEV-approved — bidirectional DC units do not qualify.

Is now the right time for bidirectional?

The honest answer: probably not, for most people. The Quasar 2 is not even on open sale — it is a pre-registration page with a "keep me updated" button. UK pricing is derived from the European list (approximately £6,100) and final GBP RRP is unconfirmed. The car compatibility list needs to grow. The installer base needs to widen. And the V2G tariff market — the mechanism by which the hardware pays for itself — is still emerging.

For the narrow group who do have a compatible car, a V2G tariff, and the appetite for early-adopter friction, the Quasar 2 is the reference product. Nothing else on the UK market does what it does at home scale. But if the goal is simply V2G-readiness — the ability to upgrade later without replacing the charger — the Zaptec Go 2 at £638 and the NexBlue Point 2 at £534 hold that position for a fraction of the cost, even though they cannot discharge the car today.

The verdict

Buy the Wallbox Pulsar Max if:

• You need a compact, proven AC charger and your wall space is limited
• You want a five-year warranty and OZEV eligibility
• You charge a Tesla or any other Type 2 EV and have no immediate need for bidirectional

Buy the Wallbox Quasar 2 if:

• You own (or have ordered) a Kia EV9 or another confirmed bidirectional car
• You have a V2G tariff and have modelled the payback arithmetic
• You accept the waiting list, the specialist install, and the three-year warranty on a £6,100 unit

For the overwhelming majority of UK households in 2026, the Pulsar Max — or any number of AC chargers in the £400–£650 bracket — is the rational purchase. The Quasar 2 is not competing with them. It is competing with a home battery, and on that comparison the maths depend entirely on a car that can talk back. If yours can, it is worth the conversation. If it cannot, spend the £513 and move on.
