The delay timer can shift charging to a chosen time.
The 25 ft cable offers more reach than a short lead, while the screen is described as displaying live charging information.
The supplied plug type and J1772 connector are stated, helping buyers check outlet and vehicle compatibility before purchase.

What to know before buying

Listing details to confirm

The listing has conflicting certification wording: the title says ETL certified, while the details list UL and the feature text claims ETL/FCC certification and cites UL and CSA standards. The claimed charging rate and range-per-hour examples are not consistent across the listing and customer summary, so treat them as estimates rather than guaranteed performance. The advertised accessories appear in feature text, but the explicit package inventory only names one EV charger. Confirm the selected listing’s certification markings and included accessories before purchase.

Who is it for?

A good fit for

Drivers with a J1772 vehicle and a compatible NEMA 14-50 outlet who want portable Level 2 charging.
Households that want to choose among several current settings or schedule charging with a delay timer.
Buyers who may benefit from a longer charging lead and a display for checking charging status.

Less suited to

Anyone without a suitable 240 V NEMA 14-50 outlet or who needs hardwired installation.
Tesla owners who need an adapter included with the charger.
Buyers who require independently confirmed certifications or a verified accessory inventory.

Customer feedback describes the charger as easy to use and praises its perceived build quality, charging speed, adjustability and cool operation. Those comments may matter to buyers seeking a portable charger with selectable current and a status display, but customer-reported range per hour depends on the vehicle and charging conditions. Durability feedback is mixed, including a report of failure after 20 uses, so the positive reports do not establish long-term reliability.

Positive themes

Customers describe the unit as sturdy and report satisfaction with charging speed and operating temperature.

Negative themes

Durability feedback includes a report that the charger stopped working after 20 uses.

Mixed feedback

Feedback is positive about perceived quality and sturdiness, while durability reports are not uniformly positive.
