The SEGUMA Wi-Fi Level 1/2 is the cord to keep in the trunk. It plugs into an ordinary household outlet with no adapter in the chain, adds roughly 3 to 5 miles of range per hour there, and carries an ETL certification that most cords at this price cannot show. The bonus is a NEMA 6-20 adapter in the box: on that outlet it runs at 16 amps and roughly triples the speed. It is the right buy as a backup, or as a primary charger for a plug-in hybrid or a very low-mileage driver — and the wrong one as the only charger for a full EV driven daily.
This is the cheapest charger we cover, and it took over the 120-volt backup slot from the discontinued MEGEAR Skysword II. Buying one well means understanding exactly what Level 1 is for. We compile published specs and owner reports and do the math — we have not bench-tested it.
Who it is for
Three buyers get real value from it: anyone who wants a cheap emergency cord in the trunk; a plug-in hybridowner whose small battery refills overnight on 120 volts; and a very low-mileage driver who plugs in every night and drives well under 40 miles a day. If you drive more than that and this would be your only charger, it will fall behind — you want a Level 2 portable instead.
The specs that matter
SEGUMA rates it at 12 amps on 120 volts and 16 amps on 240, with a J1772 connector, a NEMA 5-15 plug on the cord and a NEMA 6-20 adapter in the box, a 25-foot cable, and an ETL certification. Three things define it:
- The household plug is on the cord.No 240-volt circuit, no electrician, no install — it works from the same outlet as a lamp, and there is no adapter to lose out of the trunk. That universality is the whole point of a Level 1 backup.
- A named safety listing.It is ETL and FCC certified, and the listing names the UL 2594, UL 2231-2 and CSA C22.2 criteria it was built to. That is a far more specific claim than the vague “certified” badge most cords in this price band carry, and it is the single thing we would not compromise on for a charger that runs unattended for eight hours at a stretch.
- Level 1 speed, and its limits.At 12 amps on 120 volts it adds roughly 3 to 5 miles of range per hour — about 40 to 50 miles over a long overnight stretch. Plenty for a small battery or a short commute; too slow to keep a big battery topped up under daily driving. On a 240-volt NEMA 6-20 outlet the 16-amp mode lifts that to roughly 10 to 12 miles per hour.
What is good
For not much money, it removes a category of worry. It is cheap insurance that lives in the trunk and works anywhere there is a wall outlet, the 25-foot cable reaches a car parked across a driveway, and it ships with a storage bag. The extras earn their place rather than padding a spec sheet: the current adjusts from 6 to 16 amps, so you can dial it down for an outlet you do not know the history of; the app schedules charging onto cheaper overnight rates; and the 1.77-inch display on the unit reads out amps, volts, kilowatt-hours and elapsed time without reaching for a phone. The IP66-rated body is specified down to 22 degrees below zero.
Where it falls short
The honest limit is speed, and it is a hard one. On a household outlet it adds only ~3–5 miles of range per hour, so for anyone with a real daily commute it cannot keep up — the battery slowly falls behind. This is not a defect; it is what Level 1 is. The 16-amp Level 2 mode is the obvious answer, but it needs a NEMA 6-20outlet, which most garages do not have, and SEGUMA states plainly that the charger will not work on 6-15, 10-30 or 14-30 outlets — so do not buy it planning to plug it into a dryer socket. The warranty is one year where several rivals give two, and the scheduling runs through SEGUMA's own app rather than anything you already use.
Bottom line
The SEGUMA is what a cheap Level 1 cord should be: universal, listed, and honest about its speed. Buy it as a trunk backup, or as a primary charger only if you drive a plug-in hybrid or very few miles a day. If it would be your only charger and you drive a full EV daily, spend up for a Level 2 portable like the MUSTARTinstead — and keep this as the backup. See where it ranks in the portable roundup.
