A portable EV charger can be a useful backup at home or in the boot, but a UK three-pin unit is slower than a wallbox and the socket and wiring matter. Specification-based guide, not a hands-on test. Last checked: 16 August 2026.
Quick answer
This is a specification-based buying guide, not a hands-on laboratory test. Affiliate disclosure: this guide contains affiliate links and we may earn a commission at no extra cost to you.
For most UK drivers looking for an occasional or backup charger, the sensible specification is a UK Type G three-pin plug, a Type 2 vehicle connector, maximum output around 10A / 2.3kW, adjustable current settings, plug and control-box temperature monitoring, a clear status display, a cable long enough to reach without an extension lead, and confirmed compatibility with the vehicle.
EVDANCE currently offers UK three-pin-to-Type-2 portable chargers with 6.1m, 8m and 10m cable options depending on model, with adjustable charging current, an IP66-rated control box and various electrical protection features. Check the exact specification, warranty and final GBP price on the product page before ordering.
What is a portable EV charger?
A portable EV charger is more accurately described as portable EV supply equipment. One end connects to a suitable power socket, the control box manages the charging session, and the other end connects to the vehicle's AC charging inlet.
The UK products covered here use a normal Type G three-pin plug and a Type 2 vehicle connector. Type 2 is fitted to most modern UK and European battery-electric and plug-in hybrid vehicles, but always check the vehicle handbook or charging-port specification before buying. A three-pin charger suits emergency or backup charging, overnight top-ups away from home, holiday cottages and low-mileage use — it is not automatically a replacement for a properly installed home wallbox.
How fast is a 2.3kW three-pin EV charger?
A 10A charger on a 230V supply provides roughly 2.3kW before charging losses. The rate actually added varies with the vehicle, temperature, battery-management system and electrical supply, but around 6-8 miles of range per hour is a useful broad estimate.
Before losses, a 10kWh top-up takes about 4 hours 20 minutes, 20kWh about 8 hours 42 minutes, 40kWh about 17 hours 24 minutes and 60kWh about 26 hours 5 minutes. These are simple estimates, not promises — the car may reduce its charging rate and some energy is lost during charging.
EVDANCE UK portable charger: published highlights
Depending on version, the published features include a UK three-pin Type G plug, Type 2 vehicle connector, up to 10A / approximately 2.3kW, adjustable 6A, 8A and 10A current settings, a real-time charging display, temperature and leakage monitoring, overcurrent, overvoltage, undervoltage and overheating protection, an IP66-rated control box, cable choices up to 10m on selected versions, and a delayed charging timer on the Advanced version.
The biggest practical advantage is choosing a cable long enough to reach the car directly, because an ordinary extension lead should not be used for EV charging. Prices can be displayed in euros and the seller states final payment is processed in EUR, so check the converted total with your card provider.
The important UK safety checks
EV charging places a high continuous load on a socket for several hours. A socket that works perfectly well with a lamp or phone charger may still be unsuitable for sustained vehicle charging.
Before charging: check the plug, socket, cable and control box for damage, burning or discolouration; use a suitable socket on a sound electrical installation; do not use a normal extension lead, multi-plug adaptor or daisy-chained lead; keep the connection protected from standing water; fully uncoil the cable and keep it clear of trip and drive-over risks; stop charging if anything becomes excessively hot or smells of burning; and ask a qualified electrician to assess the installation if the socket is old, loose, damaged or intended for frequent EV charging.
Electrical Safety First lists slow EV charging as a high-load use, says it should not be used with an extension lead, and recommends a dedicated circuit with an EV-rated socket. A properly installed home charge point is normally the better long-term answer for regular daily charging.
Cable length and vehicle compatibility
Measure the real route from the socket to the charging port with the car parked normally. 6.1m suits a socket and port that are fairly close, 8m gives more flexibility for different parking positions, and 10m helps on a longer driveway and removes any temptation to use an extension lead.
The vehicle needs a Type 2 AC charging inlet. Many cars with a CCS2 rapid port also accept Type 2 AC charging through the upper section. Typical compatible families include many versions of Tesla Model 3 and Model Y, MG4, Kia e-Niro/Niro EV, Hyundai Kona Electric, Volkswagen ID models, Renault Zoe, BMW i models and numerous plug-in hybrids, but compatibility varies by model year and market. It is not a CHAdeMO charger and will not provide DC fast charging.
Frequently asked questions
Can I charge an electric car from a normal UK three-pin socket?
Some EVs can charge through suitable Mode 2 equipment connected to a UK socket, but the socket and electrical installation must be suitable for the sustained load. Three-pin charging is slow and is generally better treated as an occasional or backup option. Seek advice from a qualified electrician if you are unsure.
Can I use an extension lead with a portable EV charger?
No ordinary extension lead should be used. EV charging is a sustained high load and an unsuitable lead or connection can overheat. Choose the correct charger cable length instead.
How many miles will a 2.3kW charger add per hour?
Roughly 6-8 miles per hour is a useful estimate, but it varies by vehicle efficiency, temperature and charging losses.
Does a Type 2 charger work with a CCS2 car?
Usually, yes. CCS2 combines a Type 2 AC connection with extra DC pins below it. Confirm the individual vehicle specification before purchasing.
Is a portable charger as fast as a home wallbox?
No. A typical three-pin portable charger is around 2.3kW, while many installed home wallboxes supply up to 7kW. The vehicle's onboard charger and the electrical installation also determine the maximum rate.
Can I leave a portable EV charger in the boot?
Yes, provided it is disconnected, cool, dry, protected from damage and stored so the connector caps and cable are not crushed or contaminated.
