EO Mini Pro 3 vs Sync Energy Wall Charger 2

The £123 question — and whether size answers it

The EO Mini Pro 3 costs £523. The Sync Energy Wall Charger 2 costs £400. That £123 gap buys you one specific thing: the smallest mainstream charger on the UK market, at 215 × 140 × 100 mm — roughly the footprint of an A5 notebook. If physical space is not the constraint, the Sync Energy is the more capable unit by almost every other measure.

• EO Mini Pro 3 — the charger you buy when nothing else physically fits. £523, 5-metre cable, 7.2kW, 2.5 kg.
• Sync Energy Wall Charger 2 — the budget workhorse. £400, 7.5-metre cable, 7.4kW, IP65 + IK10, built-in PEN fault protection.

Where the Sync Energy's £400 goes further

Start with the cable. The Sync Energy gives you 7.5 metres — the longest tethered cable of any charger on the site, edging even the Tesla Wall Connector's 7.3 m. The EO Mini Pro 3 ships with 5 metres. That 2.5-metre difference is the gap between reaching the charge port comfortably and needing to reverse into a slightly different position every evening. Cable length is boring until it isn't.

Then build quality. The Sync Energy is rated IP65 + IK10 — sealed against water jets and resistant to impact. The EO carries IP54, which handles rain but not a direct hose or a stray football. If the charger sits on an exposed front wall or beside a busy driveway, the Sync Energy's enclosure is the more reassuring spec.

Built-in PEN fault protection is the Sync Energy's quiet advantage. Most chargers require a separate earth rod — an extra cost buried in the installation quote. The Sync Energy folds it in. That alone can shave £50–£100 off the install, widening the effective gap between these two units to something closer to £170–£220 in total outlay.

Both chargers offer solar diversion via CT clamp, included in the box. Neither approaches the myenergi Zappi GLO's dedicated Eco+ modes — if solar is the primary reason you're buying, that's a different comparison. But for households that want to use excess generation when it's available without building a system around it, both do the job adequately.

When the EO Mini Pro 3 earns its keep

Two scenarios make the EO's £523 defensible.

The first is physical constraint. A narrow garage pillar, a recessed wall cavity, a spot beside a doorway where anything wider would block the path — the EO at 215 × 140 × 100 mm fits where the Sync Energy's 305 × 201 × 115 mm does not. No other smart charger on the market is this small. If the wall dictates the charger, the EO is often the only option.

The second is British Gas. The Hive Power+ variant of the EO credits back 25 per cent of charging costs on the British Gas EV Power tariff. At 9p/kWh off-peak, that cashback brings the effective rate to roughly 6.75p — competitive with EDF GoElectric's 6.99p and close to Octopus Agile's best overnight slots. Over a year of typical home charging, the cashback can recoup most of the £123 premium. Outside the British Gas ecosystem, this advantage vanishes.

One note on the EO's app situation: EO Charging is retiring its own app and migrating users to ev.energy. The transition has been bumpy for some owners. The Sync Energy moved its own app platform away from Monta, so neither charger has a spotless software track record — but both now offer schedule-based tariff control, Wi-Fi, Bluetooth, and Ethernet connectivity.

Tariff scheduling — similar limits

Neither charger chases half-hourly pricing. Both handle fixed off-peak windows well: set a schedule for Octopus Go's 00:30–05:30 slot or E.ON Next Drive's 00:00–06:00 window, and each will hold to it. For Octopus Agile, where rates shift every thirty minutes, neither unit can follow the curve. That job belongs to the Ohme Home Pro at £539 — only £16 more than the EO and £139 more than the Sync Energy, but a different class of tariff intelligence. If Agile is your tariff, or likely to be, the Ohme comparison is the more useful page.

The verdict

Buy the Sync Energy Wall Charger 2 if:

• You want the longest cable (7.5 m) and the lowest price (£400) in one box
• Your charger sits on an exposed wall — IP65 + IK10 handles weather and knocks
• You'd rather the install quote didn't include a separate earth rod

Buy the EO Mini Pro 3 if:

• Your mounting spot physically cannot accommodate a standard-sized charger
• You're on British Gas Hive Power+ and the 25 per cent cashback applies
• You specifically need Ethernet and optional 4G in a compact form factor

For most households, the Sync Energy is the charger to fit. It costs £123 less, reaches further, and arrives with tougher weatherproofing and PEN protection built in. The EO Mini Pro 3 exists for the wall that won't take anything else — and on that wall, it's the right choice. Everywhere else, save the money.
