The SEGUMA NEMA 10-30 Level 1/2 EV Charger is a versatile charging solution designed for EV owners who want faster charging without installing a dedicated charging station. By utilising a common NEMA 10-30 dryer outlet, this portable charger offers Level 2 charging speeds while also supporting standard Level 1 charging through the included adapter.
Delivering up to 24 amps of charging power at 240V, the SEGUMA charger combines flexibility, portability, and smart charging features into a compact package. With adjustable current settings, scheduled charging functionality, and a durable weather-resistant design, it is well-suited for both home and travel use.

One of the standout features of the SEGUMA EV Charger is its flexibility. The charger is designed to work with a NEMA 10-30 dryer outlet, providing Level 2 charging at up to 24 amps and 240 volts.
Charging current can be adjusted to match different electrical setups. Users can select between 10A, 12A, 16A, 20A, and 24A when using the NEMA 10-30 plug, while Level 1 charging supports 10A and 12A settings.
The included 25-foot charging cable is another strong selling point. The extra cable length makes it easier to reach the vehicle's charging port in garages, driveways, or tight parking spaces without needing extension cords.
Another standout feature is the 1.77-inch TFT smart display. The screen provides real-time charging information, including voltage, current, charging duration, and charging status.
The charger also supports scheduled charging, allowing EV owners to set charging sessions during off-peak electricity hours. The feature can help reduce charging costs while making energy usage more efficient.
Durability is another area where the SEGUMA charger performs well. It features high-conductivity copper wiring, a flame-retardant TPE jacket, UL 94V-0 fire resistance, and an IP66 waterproof rating.
Compatibility is also broad thanks to the SAE J1772 connector. The charger works with virtually all electric vehicles and plug-in hybrids that use the J1772 standard. Tesla owners can also use the charger with a compatible J1772 adapter.
Moreover, safety remains a major priority. SEGUMA recommends using a dedicated 30A breaker when charging through a NEMA 10-30 outlet. For older outlets or homes with aluminum wiring, limiting charging current to 20A is advised to reduce the risk of overheating and ensure safe operation.
