Easee One Review UK (2026): The World's Smallest Smart EV Charger
Quick Verdict
The Easee One is the lightest smart home EV charger on the market at 1.5kg. It is the only home charger that works tethered and untethered from the same unit, and the only one that runs three charging points from a single fuse. In a market where most chargers do the same things in similar ways, the Easee One stands apart.

Build Quality and Design
At 1.5kg and 256mm x 193mm x 106mm, the Easee One is far lighter and smaller than most competitors. It mounts flush and sits unobtrusively on any wall. The IP54 rating handles standard UK outdoor conditions for a sheltered position. A 4G eSIM with lifetime connectivity comes built in, so the charger runs independently of your home broadband, no Wi-Fi required, no data plan to manage.
Installation
You need a 32A dedicated circuit. The Easee One's multi-charger capability is its most practical installation advantage: one fuse serves up to three units, with the system balancing power between them. For a two-car household or a small car park, this removes a portion of the electrical infrastructure cost. The charger is OZEV-approved, qualifying for the EV Chargepoint Grant where eligible. RFID access control ships built in, so you can restrict charging to authorised users from day one.
Tethered and Untethered from One Unit
Most home chargers are sold as either tethered (fixed cable) or untethered (socket only). The Easee One does both from the same hardware. You can use a tethered cable or connect via the socket and switch between the two without buying a different unit. For households with multiple EVs or anyone who wants flexibility, that removes a buying decision most other chargers force you to make at the point of purchase.
Charging Speed
7.4kW on a standard single-phase UK supply, adding 25 to 30 miles of range per hour. The Easee app has a reputation for being one of the more intuitive in the market, covering scheduling, session pause controls, and energy history.
Solar Charging
The Easee One does not include native solar diversion as standard. Adding the Easee Equalizer accessory unlocks two solar charging modes comparable to the Eco and Eco+ approach used by the Zappi. If solar diversion is central to your decision, the Zappi or Hypervolt Home 3 Pro deliver it without an additional accessory purchase.
Key Benefits
- Tethered and untethered from one unit, unique in the market
- Three chargers from one fuse, a real infrastructure saving for multi-unit installs
- Lightest smart home charger at 1.5kg
- Lifetime 4G eSIM connectivity included
- RFID access control built in
- OZEV grant eligible
Things to Consider
- Solar diversion requires the Easee Equalizer accessory, not included
- IP54 rating, adequate for sheltered positions
- Three-year warranty
Verdict
The Easee One suits drivers who want flexibility. The tethered and untethered switching, three-from-one-fuse capability, and built-in RFID set it apart from the competition. For straightforward overnight charging without solar requirements, it is a strong, compact option. If solar diversion is the priority, factor in the Equalizer accessory or look at dedicated solar chargers from the start.
