NexBlue Point 2 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 £5,566 gap and the question it asks

These are not competitors in any normal sense. The NexBlue Point 2 costs £534. The Wallbox Quasar 2 costs £6,100 — unit only, before a specialist install that adds another £1,500–£3,000. The gap is £5,566 on the sticker and considerably more once the cabling is done.

What you are paying for, in that difference, is direction. The NexBlue sends electricity into your car. The Quasar 2 sends it both ways — into the car and back out again, powering your house or exporting to the grid. That is a meaningful distinction. Whether it is a £5,566 distinction depends on circumstances most UK households do not yet have.

• NexBlue Point 2 — £534, 7.4 kW AC, ISO 15118 communication support, OZEV-approved. Charges your car. Does not discharge it.
• Wallbox Quasar 2 — £6,100, 12.8 kW bidirectional DC, UK pre-registration only. Charges and discharges your car — if your car lets it.

What "V2G-ready" means versus "V2G now"

The NexBlue Point 2 supports ISO 15118, OCPP 2.0.1, and carries the V2G-ready label. In practice, this means the hardware is built to participate in bidirectional energy flows once the standards, the cars, and the tariff products line up. It does not move power backwards today. It is a reservation — a seat at a table that has not been set.

The Quasar 2 is the table. It is a DC bidirectional charger with a CCS2 connector, capable of pushing up to 12.8 kW back into your home (V2H) or onto the grid (V2G). It works with the Kia EV9 now. Other cars are expected. But "expected" is doing heavy lifting: most UK EVs on driveways today cannot use this feature, and the Quasar 2 is still on pre-registration in the UK — you cannot open-order one as of April 2026.

The NexBlue's position is cheaper but limited to one-way AC charging today. Its OCPP 2.0.1 and ISO 15118 support may be relevant to future services, but neither proves bidirectional conversion or guarantees participation by firmware without other certified hardware.

The Quasar 2's real cost — and real audience

The unit price of £6,100 is a converted European figure; the confirmed UK RRP is still pending. Installation requires a DNO G99 application with a 30–60 working-day lead time, a specialist installer (far fewer are qualified for bidirectional DC than for standard AC wallboxes), and potentially a G100 export cap. Installed, the total is likely north of £7,600. The £500 OZEV grant does not apply.

Compare that to the NexBlue: £534 for the unit, £400–£600 for a standard install, and — for eligible renters or flat owners — the £500 OZEV grant covers the unit outright and chips into the install costs too. Total out-of-pocket for most buyers: well under £700.

The Quasar 2's warranty is 3 years. The NexBlue's is 5. The Quasar 2 weighs roughly 20 kg. The NexBlue weighs 2.1 kg. These are different categories of product, and the install reflects it.

The honest audience for the Quasar 2 today is narrow: someone who owns (or has ordered) a CCS2-compatible bidirectional car — the Kia EV9 is the main one — who has solar panels or a V2G export tariff, and who views the hardware as an investment against future grid-services revenue. For that person, it is the reference product. For everyone else, it is premature.

What the NexBlue does well on its own terms

Strip away the V2G conversation and the NexBlue Point 2 is a strong AC charger at £534. EcoPilot handles tariff automation on Octopus Intelligent Go, Octopus Agile, and other time-of-use tariffs. The included CT clamp manages dynamic load balancing and solar surplus charging without extra hardware — though solar diversion is less refined than what the myenergi Zappi GLO offers, if that matters to you. Lifetime 4G via built-in eSIM means it does not depend on your home Wi-Fi. OCPP 2.0.1 compliance is the newest open standard, giving it flexibility with future energy platforms.

The caveat remains brand maturity. NexBlue is new to UK homes, and long-term reliability data does not exist yet. If that unsettles you, the Ohme Home Pro at £539 or the Zaptec Go 2 at £638 — also V2G-ready — offer more established track records. The NexBlue Point 2 vs Ohme Home Pro comparison covers that decision in detail.

The verdict

Buy the NexBlue Point 2 if:

• You want a smart, tariff-aware charger at £534 with ISO 15118 communication support for the future
• You have solar panels and want load balancing and surplus charging without buying accessories beyond the included CT clamp
• You are OZEV-eligible and want the £500 grant to cover most of the hardware cost

Buy the Wallbox Quasar 2 if:

• You own a bidirectional-capable car — today, not theoretically — and want to use V2H backup or V2G export now
• You have solar generation or a grid-services tariff that makes exporting from your car financially rational
• You accept the pre-registration wait, the specialist install, and the £7,600+ total outlay as the cost of being first

For the vast majority of UK EV owners reading this in 2026, the NexBlue Point 2 is the sensible buy. It charges your car, it talks to your tariff, and it holds a credible position for the bidirectional future — all for less than a tenth of the Quasar 2's installed price. The Quasar 2 is impressive engineering with a narrow audience. If you are not certain you are in that audience, you are not.
