Best Portable EV Chargers UK (2026 Guide)

A portable EV charger — colloquially known as a granny charger — is the simplest way to top up an electric car without any installation work. You plug one end into a standard UK 3-pin socket (or an industrial CEE outlet), connect the other end to your car's Type 2 inlet, and charging begins. No electrician, no planning permission, no fixed unit on the wall. That simplicity comes with trade-offs, but for occasional use, holiday homes, and drivers without off-street parking, a portable EVSE is often the most practical option available.

What is a portable EV charger?

Portable EVSEs (Electric Vehicle Supply Equipment) are Mode 2 charging cables with an in-line control box that handles communication between the grid and the car. Unlike the tethered or socketed wallboxes covered in our best home EV charger guide, a portable unit requires no permanent installation — it travels with you.

Most portable chargers supplied with new EVs use the standard UK 13 A three-pin plug and deliver around 2.3 kW (10 A at 230 V). Aftermarket units often add adjustable current settings (6 A, 8 A, 10 A, 13 A) and some support industrial CEE blue (single-phase) sockets rated at 16 A, giving 3.6 kW — a useful step up for campsite hook-ups and holiday parks.

How fast does a portable charger charge?

Charging speed depends on the socket type and the car's on-board charger. A standard 3-pin 2.3 kW connection adds roughly 8–10 miles of range per hour. An industrial blue CEE 16 A socket running at 3.6 kW pushes that to around 15–16 miles per hour. For comparison, a 7.4 kW wallbox delivers 25–30 miles per hour.

For most drivers who top up overnight, a 3-pin granny charger is perfectly adequate for a daily 20–40 mile commute — you will recover far more than you use each night. Where it falls short is for a large-battery EV starting from nearly empty, or for drivers who need a full charge within a few hours.

Best portable EV chargers UK 2026

The market has matured considerably. Here are the standout models available in the UK in 2026, covering budget through to premium.

1. Cord EV Cord Plus — Best overall UK-made option

From ~£175 · 3-pin Type 2 · 2.3 kW · 5 m or 10 m cable · IP44

Made in the UK, the Cord Plus is a no-frills Mode 2 cable built to BS 7671 standards. The in-line control box carries an integrated RCD and temperature monitoring, addressing the two biggest safety concerns with sustained 3-pin charging. Available in 5 m and 10 m versions. Widely recommended by UK EV forums as a reliable, UKCA-marked option with good after-sales support.

2. Zencar Portable Charger — Best for adjustable current

From ~£150 · 3-pin or CEE blue · 2.3–3.6 kW · adjustable 6/8/10/13/16 A · IP66

Zencar's adjustable portable EVSE is popular with UK drivers who visit campsites and holiday parks. The IP66 weatherproof rating — higher than most rivals — means it can be left plugged in outdoors in UK rain. The ability to dial current down to 6 A is useful on older ring-final circuits where sustained 13 A draw is inadvisable.

3. Mustart Level 1/Level 2 Portable — Best dual-voltage option

From ~£180 · 3-pin + CEE blue bundle · 2.3–3.6 kW · IP54

Mustart's portable unit ships with both 3-pin and CEE 16 A plugs, making it one of the most versatile portable EVSEs available in the UK. The in-line LCD displays real-time current, voltage, and energy consumed — helpful if you want to track charging costs. IP54 rated; suitable for outdoor use with reasonable splash protection.

4. Voldt Portable Granny Charger — Best smart portable

From ~£220 · 3-pin Type 2 · 8–13 A adjustable · app control · IP44

Voldt's app-connected granny charger is an increasingly popular choice for drivers who want scheduled charging (for cheaper off-peak tariffs) without a wallbox. You can set charge windows, monitor energy use, and receive notifications via the companion app. UKCA certified.

5. Autel MaxiCharger Portable — Best for smart-home integration

From ~£280 · Type 2 · up to 7.4 kW (requires Type 2 socket) · Wi-Fi/Bluetooth

Strictly speaking the Autel portable is a compact untethered unit that requires a dedicated Type 2 outlet rather than a 3-pin socket — so it sits at the boundary between portable and wallbox. Its value lies in portability for those with a Type 2 socket at a second property. If you are considering this tier, our guide to EV charging with solar panels explains how pairing a smart charger with a solar array can significantly cut charging costs.

Safety: what you must know about 3-pin EV charging

A standard 13 A socket is not designed for sustained high-current loads. A conventional domestic socket on a ring final is rated for intermittent use. Running an EV charger at 10 A for 8–10 hours every night is a continuous load — exactly what the socket, plug, and wiring were not tested for over a long service life.

Key safety rules from electrical industry guidance:

• Check your wiring age. Properties built or rewired before 2008 may lack RCD protection on socket circuits. IET BS 7671 Section 722 requires RCD protection (Type A or higher) for EV charging points; a quality portable EVSE with an integrated RCD addresses this for Mode 2 use.
• Never use an extension lead. Domestic extension leads and multi-socket adaptors are not rated for sustained EV charging loads and have caused fires. Plug directly into a wall socket.
• Use a dedicated socket where possible. A socket on its own spur — rather than shared on a busy ring final — reduces the risk of cumulative overload. Have an electrician fit one if you charge regularly via 3-pin.
• Look for the integrated RCD. Quality portable EVSEs include an in-line RCD and temperature sensor. If your unit lacks these, replace it — they are the primary safety backstop when charging from a standard socket.
• Watch for warm plugs. If the 3-pin plug or socket feels warm after charging, stop using that outlet for EV charging and have it inspected. Warmth indicates resistance — a precursor to failure.

The IET's May 2024 Wiring Matters guidance on RCDs for EVSE confirms that Type A RCDs (rated ≤30 mA) are the minimum requirement where an EVSE incorporates DC fault current protection; older installations without RCDs present a genuine shock and fire risk for continuous EV loads.

When a wallbox makes more sense

A portable granny charger is a convenience tool, not a long-term primary solution. Consider upgrading to a dedicated 7 kW wallbox if:

• You charge your EV at home more than three nights per week.
• Your car's battery is larger than 40 kWh and overnight 3-pin charging leaves it incomplete.
• You want smart scheduling to take advantage of cheap overnight tariffs (many wallboxes support this natively).
• You have solar panels — a smart wallbox can be instructed to charge only when surplus solar generation is available, saving money and cutting carbon. See our overview of charging your EV with solar panels.

OZEV's Electric Vehicle Chargepoint Grant (up to £350 off installation) applies to wallboxes, not portable cables — so the cost gap between a £175 portable unit and a grant-assisted wallbox narrows considerably for eligible homeowners and renters.

Key buying checklist

• IP rating: IP44 minimum for outdoor use; IP55+ if it will be left outside regularly.
• Cable length: 5 m is fine for a dedicated garage socket; 10 m gives flexibility when parking some distance from the house.
• Integrated RCD: Non-negotiable — avoid any unit that lacks one.
• Adjustable current: Useful on older wiring; dial down to 8 A or 6 A if you are unsure of circuit health.
• UKCA / CE marking: Confirms the unit meets UK/EU safety standards.
• Warranty: Reputable brands offer 2–3 years; the supplied car cable typically carries 1 year.
