GivEnergy EV Charger vs NexBlue Point 2: Battery Storage or Future-Proofing?

Two Specialist Chargers With Very Different Bets on the Future

This is an unusual comparison. The GivEnergy EV Charger and the NexBlue Point 2 are both priced under £600, both deliver single-phase power, and both target energy-conscious homeowners. But they're placing fundamentally different bets on what matters.

GivEnergy is betting you already have a home battery. NexBlue is betting you want the smartest possible charger today, with hardware ready for a bi-directional future that hasn't quite arrived yet.

In a nutshell:

• GivEnergy EV Charger (£478): Unbeatable if you own a home battery — charge your Tesla from stored solar or cheap off-peak energy. Limited appeal otherwise.
• NexBlue Point 2 (~£530): Feature-packed smart charger with V2G readiness, smart tariff automation, and triple connectivity. A gamble on a newer brand.

Does GivEnergy's Battery-to-EV Trick Justify the Hype?

Yes — if you have the right setup. The GivEnergy charger can pull energy from your home battery to charge your car. That means solar energy stored during the day, or cheap overnight electricity soaked up at off-peak rates, can flow into your Tesla hours later. Most chargers can divert live solar surplus, but drawing from a battery is a different proposition entirely. It decouples when you generate from when you charge.

Paired with the GivEnergy monitoring portal, you get whole-home energy management: solar panels, battery, EV, all visible in one place. If you're already in the GivEnergy ecosystem, this charger slots in seamlessly at a very reasonable £478.

The problem is everything else. Strip away the battery integration and you're left with a 7kW tethered charger with a basic app, limited smart tariff support, and a 3-year warranty. The 5-metre cable is adequate but not generous. For anyone without a home battery, there are simply better options — see our cheapest EV charger guide for alternatives that cost less and do more on the software side.

Is the NexBlue Point 2 the Smartest Charger Under £600?

On paper, it's hard to argue otherwise. The spec sheet reads like a charger costing twice the price: ISO 15118 and V2G readiness, OCPP 2.0.1 compliance, dynamic load balancing with a CT clamp included in the box, and EcoPilot tariff integration that automatically hunts for the cheapest charging slots. Add in Wi-Fi, Bluetooth, and a 4G eSIM with a lifetime free data subscription, and the NexBlue is arguably the most connected charger you can buy at any price.

At 2.1 kg and roughly the size of a large hardback book, it's also tiny — less than half the weight of the GivEnergy unit. The IK10 impact rating (the highest available) means it can take a knock from a wayward football without complaint.

The catch is trust. NexBlue is a young brand without years of UK installations behind it. There are fewer reviews, fewer installers with hands-on experience, and less certainty about long-term reliability. That 5-year warranty helps, but it only matters if the company is still around to honour it. If you're comfortable being an early adopter — and plenty of tech-savvy Tesla owners are — the feature-to-price ratio here is remarkable. If you want a proven track record, the Ohme Home Pro covers similar smart tariff ground with a much longer pedigree.

Tethered vs Untethered: A Practical Split

Don't overlook this. The GivEnergy is tethered with a 5-metre Type 2 cable permanently attached. The NexBlue is untethered — a socket only, so you'll use your own cable (every Tesla ships with one). Tethered is more convenient: grab and plug, no faffing. Untethered is tidier and more flexible if you have multiple EVs with different cable lengths or if you prefer a cleaner wall installation. Neither approach is objectively better, but it's a real day-to-day difference worth thinking about before you buy.

Which Should You Buy?

Buy the GivEnergy EV Charger if:

• You have a GivEnergy home battery (or plan to install one soon)
• You want battery-to-EV charging to maximise stored solar or off-peak energy
• You're already using the GivEnergy monitoring portal and want everything in one ecosystem
• You want the lowest upfront cost at £478

Buy the NexBlue Point 2 if:

• You don't have a home battery and want the smartest charger for the money
• Smart tariff automation matters — EcoPilot does the work so you don't have to (check our tariff comparison for compatible plans)
• You want V2G and ISO 15118 readiness built in today
• A 5-year warranty and included CT clamp for load balancing appeal to you

For most Tesla owners without a home battery, the NexBlue Point 2 is the stronger buy. It's roughly £50 more than the GivEnergy but delivers meaningfully more: better smart tariff support, superior connectivity, a longer warranty, and genuine future-proofing for V2G. The GivEnergy charger is a brilliant niche product — if you're in that niche, nothing else comes close. If you're not, the NexBlue is the smarter spend.
