NIO Firefly
Charging cable
Charges about 50% faster on 22 kW public posts than a 7.4 kW cable.
Why this fits your Firefly+−
The NIO Firefly has a Type 2 inlet and a three-phase 11kW onboard charger. The 22kW cable carries its full 11kW on three-phase chargers. A 7.4kW cable would cap it. On a single-phase home wallbox both cables charge at the same 7.4kW.

Charging
the NIO Firefly.
The NIO Firefly is a compact electric hatchback and the first model from NIO's budget-oriented sub-brand, positioned to bring the NIO charging ecosystem to a more accessible price point. With a 41.2kWh battery and DC rapid charging at up to around 100kW via CCS, it is sized for city and suburban driving rather than long-haul touring. It uses a Type 2 AC inlet, the standard European connector, so a Type 2 to Type 2 cable covers all home and public AC charging. The Firefly is expected to launch from 2026, and specifications are based on currently available information.
The Firefly's onboard AC charger supports 11kW across three phases, which is notable for a car in this size class. Whether that translates into faster home charging depends on your supply: most UK homes run on a single phase, capping AC at 7.4kW. DC rapid charging via CCS uses tethered cables at rapid charge points, not a cable you buy. The 41.2kWh pack is small enough that even 7.4kW home charging fills it overnight with ease.
Estimates based on battery size and charge power. Rapid (DC) times are for a 10 to 80% charge, the way manufacturers quote them. Real-world charging varies with temperature, battery state and the charger itself.
7.4 kW or 22 kW?
Which cable does
the Firefly need?
Despite supporting 11kW AC charging, the Firefly's 41.2kWh battery is small enough that a 7.4kW Type 2 to Type 2 cable tops it up in well under six hours from empty. On a standard UK single-phase home supply, 7.4kW is the ceiling regardless of cable rating, and a 7.4kW cable gives exactly the same charge speed as a pricier 22kW one. For most owners, the standard 7.4kW cable is all that is needed.
A 22kW three-phase cable makes sense only if you regularly use 22kW public AC charge points or have a three-phase supply at your home or workplace. In either of those situations the Firefly can charge closer to its 11kW rated speed. On a typical single-phase home supply, both cable types charge the 41.2kWh pack at the same 7.4kW rate. A 5m cable covers the vast majority of home setups.
What does it cost to charge?
Filling the 41.2kWh battery from empty costs roughly £3.10 at an off-peak rate of around 7.5p per kWh, or around £11 at a standard domestic rate of around 27p per kWh. As a smaller city-focused EV, the Firefly is inexpensive to charge, and topping up daily keeps cost per mile very low on a cheap overnight tariff. Check current tariff rates before calculating your running costs.

NIO Firefly FAQs
Good
questions.
Still not sure? Our team will confirm the right cable for your vehicle.
Contact usCan the NIO Firefly charge at 22kW?+−
Yes, the NIO Firefly has a three-phase onboard charger, so with a 22kW cable and a three-phase supply it can charge at up to 11kW.
What length charging cable should I get?+−
5m suits most home and public charge points. Choose 7.5m or 10m if the charge point is far from your car's charging port or you park on the far side of a bay.
What charging cable does the NIO Firefly need?+−
A Type 2 to Type 2 cable for home wallboxes and public AC charge points. The Firefly's onboard charger supports up to 11kW on three phases. On a standard UK single-phase home supply, a 7.4kW cable delivers the full available speed. A 22kW three-phase cable only helps if you have a three-phase supply or use 22kW public AC chargers.
Can the NIO Firefly charge at 11kW at home?+−
Only on a three-phase supply, which is uncommon in UK homes. On a standard single-phase home wallbox, the Firefly charges at 7.4kW. Given the 41.2kWh battery, even 7.4kW fills the car from empty in around five to six hours, so single-phase charging is entirely practical for this size of vehicle.
How long does the NIO Firefly take to charge at home?+−
At 7.4kW on a single-phase wallbox, the 41.2kWh battery takes around five to six hours from empty. On a three-phase supply at 11kW that drops to roughly four hours. Because the battery is small, topping up from a partial charge takes considerably less time, and overnight charging from most charge levels is easily completed.
What length cable do I need for the NIO Firefly?+−
A 5m cable is the right choice for most driveways and public charge bays. The Firefly is a compact car, so in most standard parking situations a 5m lead reaches comfortably. If your wallbox is set further back, or the car parks at an awkward angle relative to the socket, a 7m lead adds a useful margin.
