Exclusive: Tesla has quietly cleared FCC certification for a product named Tesla Wall Connector 4. The filing, FCC ID 2AEIM-1997721, became public on November 4, 2026. A public label sample in the same packet names the hardware WC4-NACS-02. We checked Electrek, InsideEVs, Teslarati, Not a Tesla App, Carscoops and Google News before writing this: none had the Wall Connector 4 filing when we looked.
Tesla’s current home charger on the US shop is still the Gen 3 Wall Connector, which tops out at 48 amps. The new label shows the same 48-amp, 200–240V single-phase rating. So this looks like a next-generation box, not a higher-power one. Exterior photos and the user manual in the FCC packet stay confidential until May 4, 2027, which is why you are reading about a label and radio grants instead of a full unboxing.
What the FCC filing confirms about Wall Connector 4
Here is what is on the public record, not speculation.
Tesla, Inc. is the applicant. The device description on the grant is simply “Wall Connector 4.” Three original-equipment applications share the same FCC ID and all show a final action date of November 4, 2026:
- Bluetooth Low Energy in the 2402–2480 MHz band (Part 15 digital transmission), with a listed conducted output of 0.0016 W
- A 315 MHz transmitter under Part 15.231 (the same band class used on Tesla’s earlier Universal Wall Connector for a handle/remote-style radio)
- 13.56 MHz NFC under Part 15
Test reports in the packet are split between a “body” and a “handle,” which matches how Tesla’s Universal Wall Connector was filed: wall box plus cable handle, each with its own radios. The test lab is Sporton International (USA). Application paperwork in the grant set carries an October 19, 2026 application date; the exhibits went public with the November 4 action.
The public label sample is the most useful exhibit so far. It prints:
- Model WC4-NACS-02
- Input/output 200–240V, 48A, 50/60 Hz, single-phase
- Enclosure Type 3R (indoor/outdoor)
- Operating temperature −30°C to 50°C
- FCC ID 2AEIM-1997721 and Industry Canada ID 20098-1997721
- Made in Mexico
- Wi‑Fi and Ethernet MAC fields on the label artwork (placeholder values on the sample)
For context, Tesla’s Gen 3 Wall Connector FCC ID was 2AEIM-1470138 (“Wall Connector 3”). The Universal Wall Connector used 2AEIM-1735511 and already combined 315 MHz, BLE and 13.56 MHz. Wall Connector 4 reuses that radio mix under a new product name and a new grantee filing. That is confirmation of a named Gen 4 charger, not proof of a brand-new radio stack.
Tesla has not posted Wall Connector 4 on tesla.com/charging, has not issued a press note, and has not priced it. The current Gen 3 unit has been listing around $585 on the Tesla Shop in recent shop-change reports; treat that as the Gen 3 price, not a WC4 price.
What’s still unknown about Tesla’s Wall Connector 4
A lot. External and internal photos are under short-term confidentiality until May 4, 2027, so we cannot show the finished shape from the FCC file. The user manual is locked behind the same date. That usually means Tesla does not want the industrial design or install booklet public yet.
What we will not invent: a launch date, a shop price, a kW bump above 48A, Wi‑Fi 6 claims, load-sharing changes, PowerShare integration details, or a replacement schedule for Gen 3. None of that is in the grant. The NACS in the model string (WC4-NACS-02) fits Tesla’s North American connector, but it does not by itself say whether a J1772 or universal cable version is coming.
The honest read is narrow. Tesla has certified a product it calls Wall Connector 4, the label says WC4-NACS-02 at 48A, and the radios look like an evolution of the Universal Wall Connector kit. US homeowners who already own a Gen 3 should not rush to replace anything based on a filing alone. US shoppers waiting on a new home charger should watch the Tesla Shop and Tesla’s charging page, not treat an FCC grant as a ship date.
For the broader Tesla product pipeline, see our upcoming Tesla models for 2027 hub. Home charging still matters more to daily US ownership than most unveil videos, which is why a boring-looking FCC packet is worth flagging the day it goes public.
Would you replace a working Gen 3 Wall Connector for a Gen 4 box if Tesla kept the same 48-amp ceiling, or only if the new one brought a real feature you are missing today?
