You need enough cable reach to connect your EV without shuffling cars or adding an extension cord. This guide compares three plug configurations in the PRIMECOM 16A portable Level 2 EVSE family, including NEMA 14-50, 14-30, and 10-30 options.
The linked configurations do not all default to a 50-foot cable. The 14-50 and 14-30 links may open a 30-foot selection, while the 10-30 link is identified as a 50-foot model. Check both the plug type and cable length before you buy.

Quick Verdict
Choose the PRIMECOM 14-50 when you have a verified four-prong 14-50 outlet and want the most practical modern plug option. Choose the PRIMECOM 14-30 for a compatible four-prong 30A dryer outlet. Consider the PRIMECOM 10-30 only for an existing, professionally verified legacy three-wire outlet. For every version, confirm that the Amazon selection shows the cable length you need.

Selection Criteria
This comparison focuses on cable reach, exact NEMA plug match, 16A charging output, J1772 vehicle compatibility, portability, outlet condition, and clear safety limits. It also separates seller-listed certification claims from proof that the complete EVSE carries a specific independent safety listing.
Before You Buy
- Match the EVSE plug to the receptacle exactly. Do not rely on a casual visual guess.
- Confirm the outlet, wiring, breaker, and receptacle condition with a licensed electrician, especially for an older dryer outlet.
- Check that the Amazon selector shows both the plug type and cable length you intend to order.
- Confirm that your vehicle accepts J1772 AC charging or that you have a vehicle-approved adapter.
- Do not add a household extension cord or plug adapter unless the EVSE and vehicle manufacturers expressly allow it.
This is the most practical choice of the three when your home already has a correctly installed NEMA 14-50 receptacle. The 16A output is modest for Level 2 charging, but it can still provide useful overnight charging while keeping the unit portable.
Why Youβll Like It
- The four-prong 14-50 plug is a clearer fit for many modern 240V charging setups.
- The parent listing offers long-cable choices for garages and driveways with awkward parking.
- The portable control box is easier to move than a fixed wall station.
- The J1772 connector works with compatible EVs and plug-in hybrids.
Who Should Buy This
Choose this version when an electrician has confirmed that your 14-50 outlet and circuit are suitable for continuous EV charging, and when 16A charging is enough for your daily mileage.
Who Should Avoid This
Skip it if you need 32A, 40A, or faster home charging, if your vehicle requires a different connector without an approved adapter, or if the product page does not let you select the exact 50-foot 14-50 configuration you need.
What People Say
Feedback on the parent Amazon listing often praises the long cable and simple plug-in setup. Some buyers report long-term electronics or mounting concerns. Because the listing groups several cable lengths and plug styles, treat these comments as product-family feedback rather than proof about one exact configuration.

Certification Note
The seller listing states TΓV and CE certifications and refers to a UL-listed cable. That wording does not automatically prove that every component or every plug variant is a complete UL-listed EVSE. Check the certification marks, model number, and documentation for the exact unit before buying.
Key Benefits
- Long cable choices can reach across a garage or driveway
- Portable 16A Level 2 charging for routine overnight use
- NEMA 14-50 plug for a verified matching four-prong outlet
- J1772 connector for compatible vehicles
Check Current Amazon Availability
This version is aimed at homes with a compatible NEMA 14-30 receptacle, often found in four-prong dryer setups. It gives you the same modest 16A Level 2 output as the other variants, so the main buying decision is outlet fit and cable length, not a speed difference.
Why Youβll Like It
- It can use a verified four-prong 14-30 receptacle without changing to a different plug style.
- The portable design works well when you need to store or move the EVSE.
- A long-cable choice can help when the dryer outlet is not close to the parking spot.
- The 16A draw is within the capability of a properly installed 30A circuit, subject to local code and professional verification.
Who Should Buy This
Choose this model when your electrician confirms that your 14-30 outlet is in good condition, the circuit is suitable for continuous EV charging, and the selected cable length reaches your vehicle without an added extension cord.
Who Should Avoid This
Skip it if the outlet is shared with a dryer in a way that requires unsafe swapping, if the receptacle is worn or overheats, or if you cannot confirm a 50-foot 14-30 selection on the product page.
What People Say
Buyers commonly like the long-cable option and the ability to use an existing matching 240V receptacle. Some feedback raises concerns about mounting hardware and long-term electronics. Reviews may combine several plug and cable variants, so check whether a comment matches the setup you plan to buy.

Compatibility Note
A matching plug shape is not enough by itself. Confirm the breaker size, receptacle condition, wiring, local electrical rules, and whether another appliance shares the outlet. Stop using the setup if the plug or receptacle becomes hot, loose, discolored, or damaged.
Key Benefits
- NEMA 14-30 plug for a verified matching four-prong outlet
- Portable 16A Level 2 charging for overnight use
- Long-cable choice for difficult garage layouts
- J1772 connector for compatible vehicles
Check Current Amazon Availability
This model solves the cable-reach problem for homes that already have an older NEMA 10-30 dryer outlet. A 10-30 receptacle uses two hot conductors and a neutral, without a separate equipment grounding conductor. That makes it a more specialized choice than the four-prong 14-50 and 14-30 versions.
Why Youβll Like It
- The 50-foot cable can reach parking spots far from an existing outlet.
- The portable design is useful when a fixed wall charger is not practical.
- The 16A output can provide useful overnight Level 2 charging.
- The J1772 connector suits many compatible EVs and plug-in hybrids.
Who Should Buy This
Consider it only when you already have a NEMA 10-30 receptacle, the exact EVSE is designed for that connection, and a licensed electrician confirms the outlet and circuit are safe for the intended continuous load.
Who Should Avoid This
Do not choose it for a new outlet installation, an unknown or worn receptacle, a setup that requires an unapproved adapter, or a vehicle that cannot use J1772 without a supported adapter. A modern grounded outlet or hardwired EVSE is usually the clearer choice for new work.
What People Say
Owners often value the 50-foot reach and the ability to charge from an existing matching outlet. Some feedback mentions long-term electronics or mounting concerns. Parent-listing reviews may include other plug and cable variants, so confirm that each comment applies to the 10-30 configuration.
Feedback Pattern: Mostly positive, with added outlet-safety considerations

FAQ
Does Every Plug Option Come With a 50-Foot Cable?
Not automatically. The parent listing shows 30-foot and 50-foot size choices plus several plug styles, but the exact combinations can vary. The 14-50 and 14-30 links may open a 30-foot configuration. Confirm the selected plug and cable length in the product title, option selector, and cart.
Will This Work With My Outlet?
The plug must match the receptacle, but shape alone does not confirm a safe installation. Check the circuit voltage, breaker, wire size, receptacle quality, outlet condition, and local code. Use a licensed electrician when you are unsure. Give extra attention to older NEMA 10-30 outlets because they do not have a separate equipment grounding conductor.
How Fast Will It Charge?
At 16A and 240V, the EVSE can supply up to about 3.8 kW. Real charging time depends on your battery size, starting charge level, temperature, charging losses, and the vehicleβs onboard charger. This is useful for routine overnight charging, but it is slower than many 32A and 40A home stations.
Will It Fit My EV?
These configurations use a J1772 vehicle connector. Many EVs and plug-in hybrids accept J1772 for AC charging. A vehicle with a NACS inlet may need a compatible, vehicle-approved J1772 adapter. Check your ownerβs manual before buying.
Can I Use an Extension Cord or Plug Adapter?
Avoid adding a household extension cord or a simple plug adapter. Extra connections can add heat, create a poor ground path, or exceed the rating of the added hardware. Use only equipment that the EVSE maker, vehicle maker, and local electrical rules allow.
Is the Whole Charger UL Listed?
The seller listing refers to TΓV and CE certifications and a UL-listed cable. That is not the same as clear proof that every complete EVSE variant is UL listed. Verify the exact model number and certification mark in the current listing and product documentation.
How Should I Maintain a 50-Foot Cable?
Keep the cable free of tight kinks, standing water, sharp edges, and vehicle tires. Coil it loosely, support the control box, protect the connector from dirt and impact, and inspect the plug and receptacle for heat, looseness, discoloration, or damage.
Wrapping Up
Final Recommendation
The PRIMECOM 14-50 is the clearest overall choice when you have a verified matching outlet and can select the cable length you need. The PRIMECOM 14-30 makes sense for a verified four-prong 30A dryer outlet. The PRIMECOM 10-30 offers the most explicit 50-foot reach, but it should be reserved for a professionally checked legacy outlet. Do not choose by cable length alone. Match the plug, circuit, vehicle connector, and safety documentation first.
