The difference between V2L and V2H is where the hardware lives — and that decides whether your charger purchase matters at all. V2L (vehicle-to-load) is a feature of the car: it powers devices from an outlet on the car, and your wall charger plays no part in it. V2H (vehicle-to-home) powers your house, and it lives in a bidirectional charger wired into the home — a different product class from a normal charger, which a standard wallbox cannot be upgraded into.
Key Takeaways
- V2L lives in the car: your charger choice neither enables nor blocks it.
- V2H lives in a bidirectional charger and home transfer equipment — a separate installation, not an upgrade.
- Buying for V2L? Choose the car, and pick the charger on charging merits alone.
- Planning V2H? Don’t pay for “ready” claims on a one-way charger without the full chain in writing.
V2L: The Charger Is Not Involved
With V2L, the car itself is the power source. A socket in the car, or an adapter in its charge port, gives household-voltage power for tools, camping gear, or a fridge during an outage. The wall charger neither enables nor limits any of this: charging still runs one way, into the car, through whatever home charger you already own. If V2L is the feature you want, the buying decision is entirely about the car — confirm the model offers it, as our bidirectional charging guide sets out — and your charger budget is untouched.
V2H: The Charger Is the Installation
V2H moves the same battery energy into the home’s circuits, and that changes everything about the hardware. The car must support discharging, and the energy reaches the house through a bidirectional charger — a unit that can convert the battery’s DC power for the home and manage the connection safely. Around it sits transfer equipment that separates the home from the grid during an outage, plus the approvals the local rules require for equipment that interacts with the grid. It is a building installation designed with an electrician, not an accessory. Our overview of when vehicle-to-home will be available covers where the technology stands.
| Question | V2L | V2H |
|---|---|---|
| Where does the ability live? | In the car | In a bidirectional charger and the home wiring |
| Does your wall charger matter? | No — it only charges the car, as always | Yes — the bidirectional unit is the system |
| Extra hardware to buy | Possibly the car’s own outlet adapter | Bidirectional charger, transfer equipment, installation |
| Installation and approvals | None | Electrician-installed; grid-interaction rules apply |
Buying a Charger Today With Either in Mind
Two conclusions follow, and they save money in opposite directions.
- If V2L matters to you, spend nothing extra on the charger. Buy the car with V2L and choose your home charger on charging merits alone. A standard wallbox charges a V2L car exactly as it charges any other.
- If V2H is a future plan, a standard charger is not a step toward it. The bidirectional unit replaces the wallbox’s role in the system; today’s one-way charger cannot be converted later. That is not wasted money — it charges the car for years meanwhile — but do not pay a premium for “V2H-ready” wording on a one-way charger. Without the full chain in writing (a car that supports discharge, the bidirectional unit itself, and the approval route), the claim buys nothing.
Stated plainly for our own range: EVDANCE chargers charge cars in one direction, and EVDANCE sells no bidirectional charger or V2H system. A home unit such as the EV-ACT5006T — up to 48 A, NACS, ETL/FCC/CE listed — will charge a V2L-equipped car normally, and the residential charging page covers the rest of the one-way range. If a seller suggests an EVDANCE charger can power your home, that claim is wrong; ask us in writing instead.
Frequently Asked Questions
Do I need a special charger to use my car’s V2L?
No. V2L runs from the car to your devices and never passes through the wall charger. Any charger that charges the car is all the home hardware V2L ever needs.
Can my existing wallbox be upgraded to V2H later?
No. V2H needs a bidirectional charger designed to discharge the car into the home, plus transfer equipment. It is a separate installation, not a firmware update or an add-on for a one-way wallbox.
A car advert says “bidirectional”. Does that mean it does both V2L and V2H?
Not necessarily — the word covers both, and many cars offer V2L only. Check which function the maker means, and whether the home side exists for your market, before counting on either. The question is worth asking about any specific model, as our piece on whether a Tesla can do vehicle-to-home shows.
