Best Tethered EV Chargers for Home Charging: 2025 Expert Review
Oli at OR Electrics
18th Edition Fully Qualified Electrician
Choosing an EV charger feels complicated. You have volts, amps, smart apps, and regulations like PEN fault detection to worry about. For many homeowners, a 'tethered' unit (one with the cable permanently attached) is the preferred choice for convenience—no more wrestling with a muddy cable out of the boot every evening.
However, not all chargers are created equal. In Leeds, where we see a mix of modern earthing systems and old TN-C-S supplies in terraced streets, picking the wrong unit can lead to expensive upgrades or safety hazards. You need a charger that protects your home's consumer unit, not just one that looks fancy on the wall.
In this review, I'm comparing three units I come across often: a high-end solar-compatible favourite, a solid problem-solving tethered unit, and a budget socketed option that I've included as a smart alternative for those tight on space.

Specs vs. The Real World
The Spec: "7.4kW Fast Charging Speed"
"The manufacturer states it will charge your car at 7.4kW continuously."
This depends entirely on your home's incoming supply. Many older Leeds terraces only have a 60A main fuse. We often have to downrate chargers to around 4-5kW to prevent blowing your main cutout fuse, unless we install load management (CT clamps).
The Spec: "Plug & Play / Easy Install"
"Marketing suggests you just screw it to the wall and plug it in."
EV chargers are high-load equipment. They legally require notification to the DNO (Distribution Network Operator) and must be installed by a competent person under Part P of the Building Regulations. Incorrect installation is a serious fire risk.
My Top 3 Recommendations
Three options to cover different needs and budgets
VORSPRUNG® Alpha Max Untethered EV Charger 7.4kW | Type 1 & Type 2
Vorsprung
Whilst this is technically an 'untethered' (socketed) unit, I'm including it as the budget pick because it offers incredible value and solves a common issue in Leeds: on-street parking. If you live in a terrace and worry about vandalism to a permanent cable, this socketed unit is often the smarter choice.
The Good
- Excellent price point for a smart charger
- Built-in PEN fault detection saves money on installing an earth rod
- Socketed design is better for on-street parking (less vandalism risk)
The Bad
- You must provide your own cable (untethered)
- Plastic casing feels a bit less premium than the Zappi
Installer Tip:
If you live in a back-to-back terrace in Harehills or Armley, I actually recommend this socketed style over a tethered one. It prevents people trying to use your cable or tripping over it when you aren't charging.

Zappi
The Zappi is, in my opinion, the gold standard for home charging, especially if you have virtually any interest in solar panels now or in the future. It's built in the UK, incredibly reliable, and handles excess solar generation brilliantly to charge your car for free.
The Good
- Best-in-class solar integration (charges from excess solar)
- No earth rod required (built-in PEN protection)
- Pin code lock on the screen prevents neighbours stealing power
The Bad
- Significantly more expensive than budget rivals
- The unit is quite large physically compared to the evec
Installer Tip:
The Zappi has excellent 'load curtailment' features. If you have an electric shower and induction hob, we can set the Zappi to automatically slow down charging when you're cooking, preventing your main fuse from blowing.

evec
The evec VEC03 bridges the gap perfectly. It offers the convenience of a tethered cable (perfect for driveways) without the premium price of the Zappi. It is compact, unassuming, and gets the job done simply. A great 'fit and forget' solution.
The Good
- Integrated tethered cable is very convenient for driveway parking
- Small footprint on the wall (unobtrusive)
- Adjustable power settings are great for houses with older 60A supplies
The Bad
- App interface is functional but basic
- Cable is 5m - ensure this is long enough for your parking arrangement
Installer Tip:
This unit is IP55 rated, handling Leeds rain fine, but always try to install it somewhat sheltered from prevailing winds if possible to extend the life of the plastic housing.
