A Level 1 cord comes in the trunk of every EV, so the question is less about which charger to buy and more about whether you need to buy one in the first place. The numbers below settle it.
Last updated: August 5, 2026 — corrected the Tesla Mobile Connector price below from a stale ~$300 to its current ~$200 (Tesla’s 2026 price cut), matching the figure already used sitewide; the Lectron dual-voltage price and DOE/FHWA mileage figures remain unchanged from the August 2 verification.
Level 1 vs. Level 2, side by side
| Level 1 | Level 2 | |
|---|---|---|
| Voltage | 120V (standard outlet) | 240V (dedicated circuit) |
| Typical amperage | 12–16A | 16–48A |
| Power delivered | ~1.4–1.9 kW | ~3.8–11.5 kW |
| Range added per hour | ~3–5 miles | ~12–42 miles (up to 80 on high-power setups) |
| Full charge (60 kWh battery) | 30–40+ hours | 4–8 hours |
| Install needed | None — plug into any grounded outlet | Electrician-installed outlet or hardwire |
| Typical all-in cost | $0 (comes with the car) | $400–$1,700+ hardware and install |
| Best for | Short commutes, apartments, backup option | Long commutes, multi-EV households, fast turnaround |
The daily-mileage math
That gap between the two levels is the entire decision: the DOE's Alternative Fuels Data Center lists Level 1 at about 3–5 miles of range per hour and Level 2 at 12–80 miles per hour. Federal travel data puts the typical American driver at around 37 miles daily, and an 8–10 hour overnight session on Level 1 restores 25–50 miles, easily covering that average commute without any wall unit.
Level 1 falls short once you go beyond that average, for instance with a 60-mile round-trip commute, two EVs sharing one outlet, or a wish to fill the battery in an afternoon rather than overnight. At that stage the 6–10x leap in speed offered by Level 2 stops being a luxury and begins to save genuine time.
Start on Level 1, keep the option open
Tesla Mobile Connector
Every new Tesla carries it in the trunk; use it on a household outlet for Level 1, or add the 14-50 adapter down the road for Level 2 with no new hardware. WenStorm sells NEMA adapters for the Gen 2 Mobile Connector too, priced from $44 to $70 across its 14-30, 6-50, 14-50 and TT-30 versions.
Our best Tesla home charger guide compares it with the dedicated Wall Connector for households that outgrow Level 1.

Lectron Level 1/2 Portable EV Charger
Its dual-voltage design lets one charger serve Level 1 now and Level 2 as soon as a 240V outlet goes in, with no second purchase.
At 32A on a 14-50 outlet it supplies about 7.7 kW, comparable to many dedicated wall units.
For a comparison with Mustart and other travel chargers, see our best portable EV charger picks. WenStorm’s Level 2 Portable (32A, $219.99) is a single-voltage alternative: it plugs into a 14-50 only, with no 120V mode.
WenStorm Level 1 and Level 2 Portable EV Chargers
Two chargers are sold separately: Level 1 (16A, NEMA 5-15) for $169.99 and Level 2 (32A, NEMA 14-50) for $219.99, each with a 25-foot cable.
A 16/24/32A dial on the Level 2 unit lets you reduce output for a tighter circuit.
The electronics are in the connector handle, offered in J1772 or NACS for the same price, and every product has a 2-year warranty.
There is no app and no hardwired version, which makes it a plug-in choice and not a permanent wall box.
When to make the jump to Level 2
A dedicated Level 2 charger justifies its installation cost if daily driving often runs past the 37-mile national average, if two EVs share a circuit in your household, or if you'd simply like to stop worrying about charging. Our best home EV charger picks and best Level 2 EV charger guide rank top hardwired and plug-in units by amperage class, and our installation cost guide explains what an electrician actually bills to get you there. When Level 2 is your choice, our 40 amp vs. 48 amp EV charger guide handles the next question: how much speed the top amperage tier really buys. Uncertain which amperage tier suits your driving? Our EV charger amperage calculator works it out from your daily miles.
WenStorm sells both levels as portables, so you can match the charger to your outlet. The Level 1 Portable (16A, NEMA 5-15) is $169.99, and the Level 2 Portable (32A, NEMA 14-50) is $219.99; each has a 25-foot cable and comes in a J1772 or NACS version. If you start on Level 1, you’d buy a separate Level 2 unit when you add a 240V outlet, since they’re separate chargers rather than one dual-voltage model. Neither has an app or a hardwired option.
The bottom line
Level 1 is no compromise: at average U.S. driving distances it is genuinely enough, and costs nothing beyond the cord already in your trunk. Moving to Level 2 is about exceeding that 37-mile average and not about Level 1 being deficient. Begin with the cord that came with the car, watch how near empty you get by morning, and pay for a Level 2 install only when the numbers show you need more speed. Our cheapest EV charger guide lays out the whole price ladder, from this $0 cord to a $350 hardwired-capable unit.

Frequently Asked Questions
Does Level 1 charging suffice for everyday driving?
For many drivers it is. Federal travel data shows the average American drives about 37 miles a day, and on a standard 120V outlet a Level 1 charger adds roughly 3–5 miles of range per hour. After 8–10 hours plugged in overnight, that restores 25–50 miles, which handles the average commute without any wall unit.
What is the speed difference between Level 2 and Level 1?
The U.S. Department of Energy's Alternative Fuels Data Center reports that Level 1 charging on a standard 120V outlet gives about 3–5 miles of range per hour, whereas Level 2 on a 240V circuit gives roughly 12–80 miles per hour, depending on the charger's amperage and the vehicle's onboard charger. A typical 40–48A home Level 2 charger falls in the 28–42 miles-per-hour range, which is 6 to 10 times quicker than Level 1.
Is an electrician needed to install a Level 1 charger?
Generally no. A Level 1 charger plugs into any grounded, dedicated 120V outlet, and most EVs include one in the trunk. Do avoid extension cords and shared or daisy-chained outlets, because sustained 12–16A on aging household wiring is a frequent cause of overheating complaints on owner forums. If the only outlet nearby shares a circuit with other appliances, that alone is a reason to call an electrician.
Can I move from Level 1 to Level 2 later without replacing my charger?
In some cases, yes. Dual-voltage portable EVSEs such as the Lectron or the Tesla Mobile Connector come with both a 120V (Level 1) adapter and a 240V NEMA 14-50 (Level 2) adapter, letting you begin on a regular outlet and swap plugs once an electrician installs a 240V receptacle, with no new hardware. Chargers built for one voltage only lack that flexibility.
Should I pay for a Level 2 installation if my commute is short?
Often it isn't necessary immediately. With daily driving below 30–40 miles and 8+ hours to charge overnight, Level 1 can keep pace indefinitely, saving you the $400–$1,700+ in hardware and installation that our installation cost guide breaks down. The argument for Level 2 grows with a longer commute, a second EV at home, or a desire to top up fast during the day instead of only overnight.
Which circuit does each charging level require?
A standard, dedicated 15–20A 120V household outlet is all Level 1 requires. Level 2 requires a 240V circuit: a NEMA 14-50 outlet for plug-in units up to 40A, or a dedicated hardwired circuit (commonly 60A for a 48A charger), since the National Electrical Code requires continuous-load circuits to be rated 125% above the charger's draw.
Does WenStorm sell both Level 1 and Level 2 chargers?
WenStorm’s Level 1 Portable ($169.99, NEMA 5-15, 16A) is the plug-in-anywhere Level 1 option, and its Level 2 Portable ($219.99, NEMA 14-50, 32A) is the matching Level 2 step up once a 240V outlet is installed. They are two separate chargers rather than one dual-voltage unit.
Is the WenStorm Level 2 Portable worth it over Level 1?
Yes, provided you have or add a NEMA 14-50 outlet. WenStorm’s Level 2 Portable plugs straight into a 14-50, offers a 16/24/32A dial and a 25-foot cable, and carries a 2-year warranty; it does not offer an app or a hardwired version.
Which connector should I choose on a WenStorm portable?
Both WenStorm portables come in a J1772 or a NACS version at the same price, so choose by the port on your car; the two versions are electrically identical.
