Overview
A portable dual-voltage EV charger built with a NACS connector for Tesla Model Y, X, 3, S and Cybertruck, switching between a 120V/12A wall-outlet adapter and a faster 240V/16A NEMA 6-20 plug.
Because it covers both a standard wall outlet and a 240V circuit, it works as overnight home charging on a regular socket or as a quicker top-up when a NEMA 6-20 outlet is available, rather than being locked into one speed like a Level-1-only trickle charger. A button on the connector opens the Tesla charge port wirelessly, and a 25 ft cable plus carry bag are aimed at travel and driveway layouts. The catch is that the 240V speed only helps once that outlet is actually installed, which most homes do not have without an electrician.
- Dual voltage: 120V/12A and 240V/16A modes
- NACS connector for Tesla Model Y/X/3/S/Cybertruck
- Wireless button opens the Tesla charge port
- 25 ft cable with a carry bag for travel
Who it's for
Tesla owners who already have, or plan to add, a 240V NEMA 6-20 outlet and want one charger that also covers a plain wall socket, plus anyone who wants a travel-ready backup charger with its own carry bag. It is not for drivers of other EV brands, since the NACS connector will not fit a J1772 port.
Strengths and trade-offs
Drawn from this product's published specifications.
- Two voltage modes in one charger, 120V and 240V
- Wireless button opens the Tesla charge port without a fob
- 25 ft cable reaches most driveway layouts
- IP66 rated for outdoor and travel use
- 240V speed requires a NEMA 6-20 outlet already installed
- NACS connector limits it to Tesla vehicles only
- No owner review data yet to confirm long-term reliability
Performance notes
On 120V/12A through the included NEMA 5-15 adapter it delivers 1.44kW, roughly 2 to 5 miles of range per hour; on 240V/16A through the NEMA 6-20 plug it delivers 3.84kW, roughly 9 to 12 miles per hour, so real speed depends entirely on which outlet gets used. Built-in protection covers ground faults, overvoltage, overcharging and overheating, and the unit is rated IP66 for outdoor use, shutting off on its own once the car reports a full charge.

Questions about the Seguma EV-ACS1604T
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Can the SEGUMA EV-ACS1604T charge a Tesla Cybertruck?
Yes, the listing names the Cybertruck alongside Model Y, X, 3 and S under its NACS connector compatibility.
Do I need a separate adapter for 120V charging with this SEGUMA charger?
No, a NEMA 5-15 adapter for a standard 120V outlet is included along with the 240V NEMA 6-20 plug.
Will the SEGUMA EV-ACS1604T work on a non-Tesla EV?
Not directly, since it uses a NACS connector built for Tesla's charge port rather than the J1772 connector most other EVs use.
