The Tesla Wall Connector 4 arrival date remains unconfirmed, but FCC documents offer a useful timing clue. Tesla’s Wall Connector 4 FCC filing is public. The exterior photos are not. Under FCC short-term confidentiality rules, those photos and the user manual can stay hidden for up to about 180 days from the grant — and in this packet they are dated to open on May 4, 2027. That clock is the cleanest public clue we have for when Gen 4 could be announced or shown. This is our single deep dive on arrival timing, expected price from Gen 1–3 shop history, confirmed specs, and why a home Wall Connector sticker still matters even with Superchargers everywhere.
When Tesla Gen 4 Wall Connector Could Arrive
FCC ID 2AEIM-1997721 lists Wall Connector 4 with a final action / grant date of November 4, 2026. External photos, internal photos, test-setup photos and the user manual in that packet show an available date of May 4, 2027.
That May date lines up with the FCC’s short-term confidentiality practice: under KDB 726920, short-term confidentiality for exhibits such as external and internal photos and the user’s manual can run for a maximum of 180 days from the grant date. November 4, 2026 plus 180 calendar days lands on May 3, 2027; the filing’s May 4 available stamp is that window in practice. When short-term confidentiality ends — or sooner, if Tesla markets the product and the exhibits are released — those previously hidden images can go public on the FCC equipment-authorization site.
Important nuance: this is a design-secrecy clock, not a law that forces Tesla to announce within 180 days. Companies often reveal the product earlier so they control the first look. They can also request shorter periods or extend up to the 180-day cap. If Tesla never markets WC4, photos can still surface when the short-term hold expires.
usonwheels estimate (not official): treat now through early May 2027 as the announce / photo-release window for Wall Connector Gen 4, with a US shop listing more likely in spring to late 2027 than an immediate Gen 3 cutover. Reasoning: (1) photos locked to May 4, 2027, (2) Gen 3 is still the live US shop SKU, and (3) Tesla often clears radio grants months before a charger lands in the shop. An earlier soft launch is possible if confidentiality drops early; we have no source saying that will happen.
Wall Connector Gen 4: What’s Confirmed
From the public grant and label sample (not speculation):
- Applicant: Tesla, Inc. Device description: Wall Connector 4.
- Model on the label: WC4-NACS-02.
- Electrical: 200–240V / 48A single-phase, 50/60 Hz; Type 3R enclosure; −30°C to 50°C; Made in Mexico.
- Radios: Bluetooth Low Energy (2402–2480 MHz), 315 MHz Part 15.231, 13.56 MHz NFC — same band mix pattern as the Universal Wall Connector.
- Test reports split “body” and “handle.”
- Grant date November 4, 2026; application paperwork dated October 19, 2026.
The 48-amp ceiling matches today’s Gen 3 Wall Connector. The filing is not evidence of a higher-kW home charger on paper. Tesla has not listed Wall Connector 4 on tesla.com/charging and has not published a shop price. Full exclusive write-up: Tesla Wall Connector 4 Clears FCC.
Expected Price From Gen 1–3 Wall Connectors
Tesla has not priced Wall Connector 4. We estimate from generational launch stickers and recent Gen 3 shop moves — then explain why that home MSRP still matters next to public charging.
The Gen 1 → Gen 2 → Gen 3 price steps
Using US Tesla shop / archive trackers (especially the Tesla Motors Club charging-equipment price history, InsideEVs on Gen 3 launch, and teslawallcharger.com Gen 2 vs Gen 3):
- Gen 1 High Power Wall Connector (early Model S / Roadster-era hardwired unit): long listed near $1,200–$1,950 depending on year and SKU — a high sticker from the low-volume period.
- Gen 2 HPWC: volume-era redesign. Shop snapshots show about $550 in 2016, then a steady $500 by 2017–2019. Gen 1 → Gen 2 was a steep cut (on the order of $700–$1,400 off the old high list), not a small step. Treat that drop as a one-time mass-market reset, not a pattern Gen 4 will repeat.
- Gen 3 Wall Connector: launched January 2020 at $500 — the same launch MSRP Gen 2 had settled at. Generational delta Gen 2 → Gen 3 at launch: $0.
- Gen 3 after launch: the sticker moved a lot. TMC’s table shows stretches at $550, $495, $400, even $350, then back up. By mid-2023 the Universal kit launched near $595 while the standard unit sat near $475. As of mid-October 2026 shop trackers, Gen 3 is about $585 and Universal about $660, after a September 2026 bump from $535 / $600 (GetTesla / Not a Tesla App; teslawallcharger.com Oct 13, 2026). That September step alone is about +$50 / ~9% with no new generation.
Plain math for Gen 4 (usonwheels estimate, not official):
- If Tesla repeats the Gen 2 → Gen 3 launch pattern (flat MSRP at the then-current shop price): Gen 4 NACS box near today’s Gen 3 → about $585.
- If Tesla adds another mid-cycle-sized step like the recent ~9% bump: $585 × 1.09 ≈ $638.
- If Tesla adds a small new-generation premium of $0–$65 over today’s Gen 3 (same 48A class on the FCC label): about $585–$650.
- If a Universal-style sibling returns with a similar ~$75 gap: about $650–$725 for that kit.
We are not projecting another Gen 1 → Gen 2 style collapse. The FCC label keeps 48A, so there is no filing evidence for a “higher kW equals higher sticker” jump. Best-grounded band: $575–$650 for a NACS-only Gen 4 box, $650–$750 if Tesla also sells a Universal-style kit. Always re-check shop.tesla.com; Tesla changes accessory prices without fanfare.
Why home Wall Connector pricing still matters vs public charging
Superchargers and Destination chargers are the backup and the road-trip network. They are not a full substitute for a home Level 2 unit for most US Tesla owners who park overnight where they live. The U.S. Department of Energy’s Alternative Fuels Data Center notes that most EV drivers charge overnight at home on Level 1 or Level 2. DOE’s national charging materials have long used the same qualitative point — that a large share of charging happens at home — when explaining why residential plugs matter next to the public network.
That is why Gen 4 Wall Connector MSRP is still a real product story:
- Hardware vs installed cost: the shop sticker is only the box. A typical hardwired Level 2 install often needs a 240V circuit, panel capacity, a permit and a licensed electrician. Tesla and installers commonly quote hundreds to more than a thousand dollars for labor/materials on top of the charger — sometimes more if the panel needs an upgrade. Compare that one-time home outlay to paying Supercharger or other public $/kWh every week for daily miles.
- Overnight Level 2 vs travel charging: home Level 2 is usually the cheap, convenient way to wake up with range. Public DC fast charging is for trips, unexpected top-ups, or drivers without a plug at home. Pricing the wall unit as if Superchargers replaced it misses how US ownership actually works for single-family driveways.
- Gen 4 at ~$575–$650 (our estimate) is still in the same ballpark as today’s Gen 3. The bigger bill for many households will remain the install, not a $50–$65 hardware step.
Apartment and street-parking owners are a different case — public and workplace charging can be primary. For driveway Tesla households, Gen 4’s arrival date and home MSRP are still the right questions.
Expected Specs for Tesla Gen 4 Wall Connector
- Confirmed (FCC label / grants): WC4-NACS-02; 200–240V single-phase; 48A; Type 3R; −30°C to 50°C; BLE + 315 MHz + NFC; Made in Mexico; FCC ID 2AEIM-1997721.
- Reported / inferred from filing structure: separate body and handle radio paths (Universal-style). Wi‑Fi and Ethernet MAC fields on the label artwork mean the artwork expects network IDs — not a published Wi‑Fi 6 claim.
- usonwheels estimate: about 11.5 kW at 240V / 48A if the label rating is the retail ceiling (same math as Gen 3). Cable length, power-sharing count, Powershare behavior and app features are not in the public exhibits we can quote.
- Still unknown: exterior design, US on-sale date, Gen 3 replacement schedule, Universal/J1772 sibling SKU.
How we estimated arrival and price
Arrival window: FCC grant date November 4, 2026 + short-term confidentiality practice (KDB 726920, max 180 days) and the packet’s May 4, 2027 photo/manual available date — framed as a secrecy clock, not a forced announce deadline. Price: Gen 1–3 launch stickers and recent Gen 3 / Universal shop steps from TMC archives, InsideEVs, GetTesla/NATA and teslawallcharger.com; Gen 1→2 treated as a one-time reset. Specs: public FCC label and grants only for confirmed items. Home-vs-public framing: DOE AFDC home-charging guidance. None of the estimates are Tesla statements or leaks.

If Tesla shows Wall Connector 4 photos before May 2027 and prices the NACS box near today’s Gen 3, would you hardwire a new unit — or keep Gen 3 and spend the install budget elsewhere?
