What to know before buying

Listing details to confirm

Listing details are inconsistent: the title says 25FT, while a separate item-length field says 16 inches. Dimensions are also given as 43D x 33W x 12H centimetres and 43 x 33 x 12 cm; 5.24 kg. The title claims ETL certification, but the specification field lists UL. Confirm the selected listing's cable length, dimensions, certification and plug configuration before purchase. The listing specifies a NEMA 14-50 plug and 240 V input, so confirm outlet and circuit suitability. A Tesla J1772-to-NACS adapter is needed and is not confirmed as included.

Who is it for?

A good fit for

Drivers with a J1772 vehicle and a compatible 240 V outlet seeking adjustable current and delayed charging.
Buyers who want a portable charger with a longer listed cable and an on-device charging display.

Less suited to

Drivers who need a charger that connects directly to a NACS vehicle without an adapter.
Buyers whose available circuit or outlet is not compatible with the listed 240 V input and NEMA 14-50 plug.

Customer feedback is generally favourable, with reported positives around charging performance, ease of use, build quality and current adjustment. The listing claims up to 40A and selectable current settings, which give context to those reports, but customer impressions do not establish that every vehicle or circuit will deliver the claimed charging rate. Ratings are mostly five-star, with a smaller spread across lower star categories, so experiences are not uniformly positive.
