EV Charging Experts
In this guide, we break down portable ev chargers including how to choose one that best suits your needs, and when they really come in handy.
As electric vehicles (EVs) become more common, many drivers need charging solutions that travel with them rather than being fixed in one spot. That’s where portable EV chargers come in.
A portable EV charger—sometimes called a “mobile EVSE”—combines all necessary charging electronics into a single unit that plugs directly into your car’s inlet on one end and into a suitable outlet on the other. Unlike a permanently installed Level 2 station, which is hardwired or plugged into a dedicated 240 V outlet in your garage, a portable charger can be moved from home to workplace to vacation home, provided there is a compatible outlet.
A permanent Level 2 station is typically wired into your home’s electrical panel and mounted on a wall, providing a reliable 240 V feed whenever you pull into your garage. By contrast, a portable charger packages its own transformer, safety interlocks (such as a ground‐fault circuit interrupter), and onboard controls into a weatherproof enclosure. One end of its tethered cable carries the familiar SAE J1772 plug that fits nearly every non-Tesla EV sold in North America (with an adapter, many Teslas also accept J1772). The other end can be fitted with interchangeable plugs—most commonly a NEMA 14-50 or NEMA 6-50—which let you draw from existing 240 V receptacles found in many homes, RV parks, or workplaces.
A quality portable charger also lets you adjust its amperage to match the circuit you’re using. For example, if you plug into a 20 A/240 V outlet, you might dial down to 16 A; if you later find a 50 A/240 V receptacle, you can boost to 40 A or more to maximize charging speed. This adaptability ensures you never overload the circuit, and it also future‐proofs your investment: should you move to a home with a higher-amperage feed, your one portable charger can still serve you.
A portable EV charger becomes especially appealing—or even necessary—in several scenarios. First, if you rent or live in multiunit housing and cannot install a hardwired Level 2 station, a portable unit lets you use any 240 V outlet your landlord, property manager, or HOA agrees to provide. Instead of paying to install a permanently mounted station that you’ll have to leave behind when you move, you simply tuck the portable charger in your trunk. Should you relocate, you bring it with you, plug into any properly wired outlet, and continue charging without a hitch.
Second, even homeowners who have a dedicated Level 2 charger might keep a portable EV charger as a convenient backup. If your fixed station fails or requires maintenance, a portable unit ensures you still have Level 2 capability—no need to rely on slower Level 1 (120 V) charging or make emergency runs to public stations.
Lastly, portable chargers shine during travel. Many RV parks, campsites, or vacation homes offer NEMA 14-50 outlets for recreational vehicles. Having your portable EV charger means you never assume whether a public EV charging station will be available; you simply plug into the RV outlet and regain 20–30 miles of range per hour, far faster than Level 1.
When choosing a portable charger, you want reliability, safety, adjustability, and sufficient cable length to reach your vehicle in a variety of parking situations. Below are some leading options that balance performance and build quality:
The Asani portable EV charger automatically senses whether it’s plugged into 120 V or 240 V power, switching between Level 1 and Level 2 modes accordingly. On 120 V, it can draw up to 16 A—faster than most OEM Level 1 cables—while on 240 V it delivers as much as 48 A for up to 11.5 kW charging. Its 25 ft tethered cable and small LCD screen—displaying real-time voltage and amperage—give you precise feedback on any outlet you use. Because the same hardware serves both voltage levels, Asani’s unit flexes from slow overnight charging to near-full Level 2 speeds.
Lectron’s portable units combine Level 1 (12 A at 120 V) and Level 2 (40 A at 240 V) functionality in a single, compact package. It comes equipped with both NEMA 5-15 and NEMA 14-50 connectors, letting you plug into a common 120 V outlet or a 240 V receptacle capable of delivering up to 40 A (9.6 kW). The 25-foot integrated SAE J1772 cable provides plenty of slack for most parking configurations, and the IP54-rated enclosure guards against dust and light moisture. A built-in LED screen displays live voltage and amperage readings, making it easy to verify proper hookup and prevent circuit overloads. In short, it’s perfect for EV drivers seeking one all-in-one charger that handles both trickle charging and faster Level 2 charging without the need for additional adapters.
Although designed primarily for Tesla vehicles, the Tesla Mobile Connector (MC)—paired with a Tesla-to-J1772 adapter—works flawlessly on any J1772 EV. When plugged into a NEMA 14-50 outlet, it delivers 32 A (7.7 kW), matching many non-Tesla EVs’ onboard charger capacity. Thanks to Tesla’s retractable cord design, storage is tidy, and build quality is excellent. If you already own a Tesla or plan to switch brands in the future, the MC’s dual-use capability makes it a versatile choice.
Not all portable chargers deliver the same speed or fit every EV. To pick the best unit, consider these factors:
First, check your car’s onboard AC charging limit. If your BEV accepts only 7.2 kW—common in vehicles like the Chevy Bolt or Nissan Leaf—there’s little benefit in paying for a 48 A (11.5 kW) charger. A 30 A (7.2 kW) unit will recharge your battery as fast as possible. Conversely, if you drive a Tesla Model 3 Long Range, Ford Mustang Mach-E, or Kia EV6, whose onboard chargers handle 11 kW, choosing a 40 A/48 A portable unit maximizes your charging speed. In short, match the EVSE’s output to your car’s top AC acceptance to avoid paying for unused capacity.
Determine which outlets you’ll most often encounter. If your home or travel destinations reliably offer NEMA 14-50 outlets, select a charger with a 14-50 plug (like the Tesla MC). If you expect to see NEMA 6-50 outlets in workshops or RV parks, look for models that include interchangeable plugs—or order the optional NEMA 6-50 adapter. If you occasionally plug into a 120 V outlet, a dual-voltage portable like Asani ensures you get at least Level 1 charging anywhere.
A capable portable charger will let you reduce output when you’re on a weaker circuit. If you plan to plug into unknown outlets—airports, friend’s homes, campground hookups—having a dial or DIP switch to drop from 40 A to 16 A protects you from tripping breakers or overheating wiring. If you only ever use one kind of outlet, a fixed-output unit might suffice, but adjustable models offer future flexibility if your needs change.
Portable units spend more time outdoors or in varied conditions than a wall-mounted station. Look for IP54, IP65, or IP67 ratings—ensuring protection from dust and water spray. Sturdy polycarbonate or cast-aluminum housings withstand impacts and UV light. Brands like ClipperCreek, Asani, and RF are known for rugged durability that resists cracking, water ingress, and corrosion.
A 25–30 ft cable gives you flexibility to park in deep driveways or far from outlets. When not in use, look for models with retractable cords (Tesla MC) or dedicated storage bags and wall-mount hooks. A well-designed storage solution prevents tangled cables, reduces wear on the plug ends, and minimizes trip hazards in the garage.
While permanently installed Level 2 stations deliver the fastest, most convenient home charging experience, portable chargers have unique benefits—and a few drawbacks—to weigh:
Pros (Why You Might Choose a Portable EV Charger)
Cons (Drawbacks to Consider)
For EV owners who need charging flexibility—whether due to renting, traveling, or simply wanting a reliable backup—a portable EV charger strikes the perfect balance between performance and convenience. By matching your charger’s amperage to your car’s onboard capacity, choosing the correct plug type for outlets you expect to encounter, and prioritizing build quality and cable length, you ensure you always arrive home or at your destination with plenty of charge. With top options such as the Lectron Portable Charger, Asani Dual-Voltage, or Tesla Mobile Connector with adapter, a single portable EV charger can serve your needs from day one through every move—making electric driving less about where you charge and more about how you drive.
