Two Compact Chargers at Very Different Price Points
The Easee One and EO Mini Pro 3 are both pitched at buyers who want something small and unobtrusive on the wall. They're the two lightest, most compact home chargers you can buy in the UK right now. But there's a £145 gap between them, and the feature sets diverge in ways that matter.
In a nutshell:
- Easee One (£405): Best overall value — lifetime 4G, featherlight at 1.5 kg, and the cheapest smart charger you can buy
- EO Mini Pro 3 (£550): Best for solar owners or anyone with extremely limited wall space — includes CT clamp solar diversion out of the box
Is the Easee One Worth £145 Less Than the EO Mini Pro 3?
Bluntly, yes — for most buyers. At £405, the Easee One is the cheapest smart charger on the UK market, and it doesn't feel like a budget product. You get dynamic load balancing, scheduled charging, and — crucially — a built-in eSIM with a lifetime 4G data subscription. That last point matters more than people realise. Wi-Fi in a garage or on a driveway can be patchy. The Easee just works, straight out of the box, with no dongles or signal boosters needed.
The EO Mini Pro 3 has Wi-Fi, Bluetooth, and Ethernet (the most connection options of any charger), plus optional 4G as a paid add-on. Ethernet is rock-solid if you can run a cable, but most people can't easily get an Ethernet run to their charger location. For the majority of installations, the Easee's included 4G is the more practical solution — and it costs nothing extra.
The Easee also integrates RCD Type-B and open PEN protection, which can trim your installation bill. Check our cheapest EV charger guide for a breakdown of total installed costs.
Does the EO Mini Pro 3's Solar Diversion Justify the Premium?
This is the one area where the EO Mini Pro 3 has a genuine edge. It ships with a CT clamp for solar diversion, meaning it can automatically use surplus solar generation to charge your car. The Easee One has no solar capability whatsoever.
If you have solar panels — or plan to install them — that's a meaningful feature. Charging from your own roof is essentially free electricity, and the EO handles this without needing any additional hardware purchases. That said, if solar is your primary motivation, the myenergi Zappi remains the gold standard with more sophisticated diversion modes. We cover this in detail in our best EV charger for solar guide.
For non-solar households, this feature is irrelevant, and the price premium becomes harder to justify.
Tethered vs Untethered: A Real-World Difference
The EO Mini Pro 3 comes tethered with a 5-metre Type 2 cable permanently attached. The Easee One is untethered — a socket on the wall, and you bring your own cable. Every Tesla ships with a Type 2 cable, so this isn't an issue for Tesla owners specifically, but it does mean an extra step each time you charge: fetching the cable from your boot, plugging both ends in, and stowing it again afterwards.
A tethered charger is simply more convenient day-to-day. You pull up, grab the cable off the wall, plug in, done. If that convenience matters to you, score one for the EO. If you prefer a cleaner wall mount or charge multiple vehicles with different cable lengths, the Easee's untethered design is actually an advantage.
Smart Tariff Support: Neither Is Best-in-Class
Both chargers offer scheduled charging, so you can manually set them to charge during off-peak hours on tariffs like Octopus Go. The EO Mini Pro 3 goes slightly further with smart tariff presets for Octopus Go, EDF Go Electric, and others, plus a British Gas Power+ feature that credits back 25% of charging costs if you're in the Hive ecosystem.
Neither charger offers the fully automated, rate-optimising smart tariff integration you'd get from an Ohme. If minimising your electricity bill is the top priority, look at our smart tariff comparison and consider whether a charger with deeper tariff integration might serve you better. For most people, basic scheduling gets you 90% of the savings anyway.
Which Should You Buy?
Buy the Easee One if:
- You want the lowest purchase price for a smart charger
- Reliable 4G connectivity without ongoing costs matters to you
- You don't have solar panels
- You're happy using the Type 2 cable that came with your Tesla
Buy the EO Mini Pro 3 if:
- You have solar panels and want built-in diversion without buying a Zappi
- Your installation space is genuinely constrained — it's A5-sized
- You're a British Gas/Hive customer who can benefit from Power+ cashback
- You prefer a tethered cable for daily convenience
For the typical Tesla owner without solar panels, the Easee One is the smarter buy. It's £145 cheaper, has better out-of-the-box connectivity, and delivers everything most households actually need from a home charger. The EO Mini Pro 3 is a solid charger with a clear niche — but that niche is narrower than its feature list might suggest.
