Budget Charger vs Future-Proofed: Easee One or Zaptec Go 2?
These two are both untethered, both compact, both come with free 4G connectivity — and yet they're aimed at quite different buyers. The Easee One costs £405 and does the job brilliantly right now. The Zaptec Go 2 costs £707 and bets on a future where your car feeds energy back to the grid. That £302 gap is the real question here.
In a nutshell:
- Easee One: The cheapest quality charger you can buy, with lifetime 4G and the lightest install going
- Zaptec Go 2: V2G-ready with a 5-year warranty and three-phase support for those who need it
Is V2G Actually Worth Paying For Today?
The Zaptec Go 2's headline feature is V2G readiness — vehicle-to-grid, where your Tesla's battery can export power back to your home or the grid during peak pricing. It's a compelling concept. But right now, V2G over AC is barely functional in the UK. You need a compatible vehicle (most Teslas don't support AC V2G yet), a participating energy supplier, and regulatory frameworks that are still being finalised.
So you're paying a £302 premium for hardware that might become useful in two, three, maybe five years. If you're the sort of person who bought a smart meter before anyone else and enjoys being early, fair enough. But for the majority of Tesla owners who just want reliable overnight charging, it's money spent on a promise.
The Easee One's Price Advantage Is Hard to Ignore
At £405, the Easee One is the cheapest charger we track — check our cheapest EV charger guide for the full picture. That price includes built-in RCD Type-B and open PEN protection, which means your installer doesn't need to add expensive extras to the consumer unit. Factor that in and the total installed cost gap between these two could stretch well beyond £302.
The Easee is also absurdly light at 1.5 kg. That's less than half the Zaptec's 3.2 kg. Your installer will thank you — lighter units mean simpler mounting, fewer fixings, and less stress on the wall. It's a small thing, but it speaks to how well Easee has thought about keeping costs down across the board.
Both chargers include subscription-free 4G, which is a welcome change from units that rely solely on your home Wi-Fi signal reaching the driveway. The Easee's built-in eSIM and the Zaptec's 4G module both work without ongoing fees, so there's no difference there.
Where the Zaptec Go 2 Earns Its Keep
Two things genuinely separate the Zaptec from the Easee beyond V2G.
First, three-phase support. The Zaptec Go 2 can deliver up to 22kW on a three-phase supply, while the Easee One is locked to single-phase 7.4kW. If you have three-phase power — or plan to upgrade — the Zaptec is one of the more affordable ways to get 22kW charging at home. That's roughly three times the speed, which matters if you drive high mileage or come home with a near-empty battery regularly.
Second, the warranty. Five years from Zaptec versus three from Easee. Over the life of the charger, that extra cover has real value — especially on a unit with more complex internals handling V2G and phase-switching. The Zaptec also has a MID-approved energy meter built in, which is useful if you need accurate billing records for a company car or shared charging arrangement.
If you're interested in solar integration, the Zaptec's ability to auto-switch between single and three-phase charging makes it a surprisingly capable option. Our best EV charger for solar guide covers this in more detail.
Which Should You Buy?
Buy the Easee One if you:
- Want the lowest possible total cost for a quality smart charger
- Have a standard single-phase supply (like most UK homes)
- Value simplicity — plug in, schedule, done
- Want dynamic load balancing for adding a second charger later
Buy the Zaptec Go 2 if you:
- Have three-phase power and want 22kW charging
- Want to be ready for V2G when it matures
- Need a MID-approved meter for company car or expense tracking
- Prefer a longer 5-year warranty for peace of mind
For the typical Tesla owner on a single-phase supply, the Easee One is the obvious pick. It's nearly half the price, featherweight to install, and has all the smart features you actually need today. The Zaptec Go 2 is a well-engineered charger with a genuine forward-looking proposition — but most people shouldn't pay £302 extra for features they can't use yet. If your priority is getting the best smart EV charger for the money right now, the Easee wins comfortably.
