EO Mini Pro vs Easee One: UK Home Charger Comparison

The EO Mini Pro 3 and Easee One are both compact, well-specified smart home EV chargers that appeal to the same type of buyer: someone who wants a reliable, connected wallbox without paying for features they do not need, but who also wants something more capable than the bare minimum. The Easee One wins on connectivity (4G eSIM built in), flexibility (lockable socket = tethered or untethered from one unit), and Octopus Intelligent Go support. The EO Mini Pro 3 wins if you have solar panels (CT clamp included, the only one at this price with proper solar mode), want the smallest physical footprint, or need three-phase support for future flexibility.

Head-to-head spec comparison

Output	7.2kW (single-phase) / 22kW (three-phase)	7.4kW (single-phase only)
Tethered/socket	Both (5m tethered or socket)	Untethered (lockable socket = semi-tethered)
IP rating	IP55	IP54
Connectivity	Wi-Fi + Bluetooth + Ethernet (4G optional extra)	Built-in 4G eSIM (lifetime, no Wi-Fi needed)
Solar diversion	Yes (CT clamp included)	No
Intelligent Octopus Go	Yes (via schedule)	Yes (native API)
Dynamic load balancing	Basic	Yes (up to 3 units, 1 fuse)
Size	215mm x 140mm x 100mm (UK’s smallest)	Compact, 1.5kg (UK’s lightest)
App	EO Smart Charging	Easee
Warranty	3 years	3 years
Unit price	~£550	~£405
Price difference		EO costs ~£145 more

Connectivity: Easee wins

The Easee One has a built-in 4G eSIM with lifetime connectivity at no extra cost. This means it never depends on your home Wi-Fi network. If your router goes down, the Easee’s smart charging schedules continue to run. If the charger is installed at a distance from the house (long driveway, detached garage), no Wi-Fi extender is needed.

The EO Mini Pro 3 connects via Wi-Fi, Bluetooth, and Ethernet as standard. 4G is available but costs extra (a 4G module add-on). For most homes with reliable Wi-Fi near the charger position, this is adequate. For longer cable runs or properties with patchy Wi-Fi coverage, the Easee’s built-in 4G is a meaningful advantage.

Verdict on connectivity: Easee One wins with built-in 4G eSIM.

Solar integration: EO Mini Pro 3 wins

This is the most significant difference between the two chargers. The EO Mini Pro 3 includes a CT clamp for solar diversion as standard. It can monitor your solar generation and household consumption in real time, diverting surplus solar electricity to your car rather than exporting it to the grid.

The Easee One has no solar mode at all. If you have solar panels, the Easee One is not the right charger.

The EO Mini Pro 3’s solar mode is not as sophisticated as the myenergi Zappi’s dedicated Eco/Eco+ system (which is the benchmark for solar diversion), but it provides a functional solar divert capability at a price that undercuts the Zappi significantly.

Verdict on solar: EO Mini Pro 3 wins. It is the most affordable solar-capable home charger in the UK market.

Tariff integration: Easee edges ahead

Both chargers integrate with Octopus Energy. The Easee One has a native API connection to Intelligent Octopus Go, enabling full smart dispatch. The EO Mini Pro 3 can also be used with Intelligent Octopus Go but relies on schedule-based operation rather than a direct API link, meaning it participates in the guaranteed overnight window but may not capture all the smart dispatch bonus slots.

The EO Mini Pro 3 also supports preset tariff schedules for Octopus Go and EDF GoElectric.

Verdict on tariff integration: Easee One has a marginal edge for Octopus Intelligent Go users. Both work adequately on scheduled overnight charging.

Load balancing: Easee wins

The Easee One’s dynamic load balancing is a standout feature. Up to three Easee chargers can share a single fuse, with power distributed automatically between vehicles depending on how many are connected and charging simultaneously. If one car is at 90% and slowing its charge, that freed capacity is automatically redirected to the other car.

This makes the Easee particularly attractive for:

• Households with two EVs.
• Managed residential properties where multiple charge points are needed.
• Installations where adding a second charger in future is anticipated.

The EO Mini Pro 3 has basic load balancing but not the multi-unit coordination that the Easee offers.

Verdict on load balancing: Easee One wins clearly.

Physical size: EO Mini Pro 3 wins

At 215mm x 140mm x 100mm, the EO Mini Pro 3 is the smallest home EV charger on the UK market. If the installation position has limited wall space, or aesthetics strongly favour a minimal footprint, the EO wins.

The Easee One is also compact and at 1.5kg is the lightest charger on the UK market, but its form factor is slightly larger than the EO. Both are smaller and lighter than most competitors.

Verdict on size: EO Mini Pro 3 is the smallest; Easee One is the lightest.

Three-phase capability: EO Mini Pro 3 only

The EO Mini Pro 3 supports up to 22kW AC on a three-phase supply. The Easee One is single-phase only (7.4kW maximum). For the small number of UK homes that already have a three-phase supply and may want 11kW or 22kW charging in future, the EO is the more future-proof choice.

For all other buyers (the vast majority of UK homes on single-phase), this is irrelevant to the buying decision.

Price comparison

Item	EO Mini Pro 3	Easee One
Unit only	~£550	~£405
Standard installation	£400-£500	£400-£500
Total installed	~£1,000-£1,100	~£850-£950
OZEV grant (if eligible)	Up to £500	Up to £500
After grant	~£500-£600	~£350-£450

The Easee One is the more affordable choice by approximately £145 in unit cost.

Which should you choose?

Choose the EO Mini Pro 3 if:

• You have solar panels and want solar diversion without paying Zappi prices.
• You need the smallest possible physical footprint.
• You might upgrade to three-phase power in future.
• You want Ethernet connectivity for a more reliable wired connection.

Choose the Easee One if:

• You have no solar panels and need a well-connected smart charger.
• Your charger is far from the Wi-Fi router (4G eSIM handles this).
• You have or plan two EVs (load balancing across units).
• Budget is a consideration (£145 cheaper unit cost).
• You want the lockable socket flexibility (semi-tethered operation).

Consider the Zappi instead if: Solar diversion is your primary need and you want the best implementation available. The Zappi’s dedicated Eco/Eco+ modes are significantly more sophisticated than EO’s solar mode, for a higher unit price.
