Pros and cons

Pros

Two outlet configurations allow use with standard 120V household outlets or a suitable 240V NEMA 6-20 circuit.
Selectable current accommodates the lower 5-15 outlet limit and the higher 6-20 setting.
The NACS connector avoids a separate NACS adapter for vehicles with a compatible NACS inlet, according to the listing.

What to know before buying

Use only an amperage appropriate for the outlet and circuit. The listing specifies a 15A circuit with 12A or lower for NEMA 5-15, and a 20A circuit for 16A charging on NEMA 6-20. It advises lower current for older outlets or aluminum wiring.
Charging speed varies with voltage, selected amperage, vehicle and battery level. The listing's miles-per-hour figures are estimates, not guaranteed rates.

Listing details to confirm

The listing gives conflicting cable lengths: the title says 21ft, while feature text says 25 feet. It also inconsistently describes the 5-15 to 6-20 adapter and the included 6-20 adapter. ETL/CSA certification and Type 4 weatherproof claims are listing claims, not independently confirmed here. Verify cable length, included adapter and certification details for the selected listing before purchase.

Who is it for?

A good fit for

Tesla owners who want one portable charger for both 120V household outlets and a suitable 240V NEMA 6-20 outlet.
Drivers whose vehicle has a compatible NACS inlet and who can match the charger setting to the circuit available.

Less suited to

Buyers who need faster charging than the listed 16A maximum or need a different outlet configuration.
Anyone who cannot confirm that their outlet, circuit and vehicle inlet match the charger's requirements.

Frequently asked questions

What outlets does this SEGUMA charger support?

The listing specifies a NEMA 5-15 outlet for 120V Level 1 charging and a NEMA 6-20 outlet for 240V Level 2 charging using an adapter. Confirm the included adapter because the listing describes it inconsistently.

Which current settings can I select?

The listing gives settings of 6A, 8A, 10A and 12A for NEMA 5-15, and adds 16A for NEMA 6-20. Follow its circuit guidance and choose a setting suitable for your installation.

Which vehicles does it fit?

The listing names Tesla Model 3, Model Y, Model S and Model X, plus compatible vehicles with a native NACS charging port. Confirm that your vehicle's inlet is compatible.

How long is the cable?

The title says 21ft, while feature text says 25 feet. The listed length is therefore contradictory, so confirm it with the selected listing before buying.
