Vehicle-to-Load (V2L) lets a Tesla power outside devices from its battery, but what it costs to get depends entirely on which car you own. For newer Model Y Premium and Performance trims, it’s an $80 accessory. For older Model Ys, it’s a parts bill north of $1,700 with no official program to get it done.
New cars: $80 and a cable
Tesla began selling a $80 Outlet Adapter for the Model Y Premium and Performance in the U.S. in mid-August 2026, according to Electrek. It plugs into the Gen 3 Mobile Connector that ships with new Model Ys and outputs 2.4 kW through a standard 120V household socket at 20 amps. It only works on vehicles built with the newer PCS2 power conversion hardware; the Model Y Standard and the Model 3 lineup aren’t compatible. It’s the same part, at the same price and power ceiling, that Tesla launched for Cybertruck owners back in April 2025.
Older cars: a $1,750 retrofit, if you can get it
Owners of older Model Ys built with the earlier PCS1 hardware don’t have that option yet. Not a Tesla App reported on August 17, 2026 that Tesla has published a draft retrofit procedure swapping the PCS1 unit for a PCS2-Lite, but the job is far from simple. The documentation runs 344 steps and requires putting the car on a lift, isolating the high-voltage battery, draining and refilling coolant, opening the battery’s ancillary bay, modifying wiring, and replacing the power conversion unit itself. The PCS2 part alone (part number 2100145-N0-E) runs about $1,750, before adding a 12V DC harness, an AC filter harness, and revised coolant hoses. Once installed, output is capped at the same 2.4 kW as the factory adapter — there’s no extra capability for the extra cost. Critically, Tesla has not announced a customer-facing retrofit program or said service centers will perform this upgrade just to add V2L, so there’s currently no formal path for most owners to request it.
