Yes — one portable charger can serve a main home and a vacation home, and a unit like the EV-ACS4005T is built for that pattern: it plugs into a NEMA 14-50 outlet and adjusts from 16 to 40 A. What makes it work is the routine: a suitable 240 V outlet waiting at each house, and the current set for the circuit you are plugged into that night.
Key Takeaways
- One portable charger can serve two homes if each property has a suitable 240 V outlet waiting.
- The current setting belongs to the house, not the charger: 40 A on a 50 A circuit, 24 A on a 30 A circuit.
- Set and read back the current on the display at every arrival, in both directions.
- Inspect the connector and cable on the first charge of each visit; transit and storage cause the wear.
What Each House Needs Before the Charger Arrives
The charger is the same at both addresses; the electrical side rarely is. How fast a portable charger runs depends on the outlet behind it, so check both properties before the first trip.
| Location | Circuit to confirm | ACS4005T setting |
|---|---|---|
| Main home | NEMA 14-50 outlet on a 50 A breaker | 40 A (9.6 kW) |
| Vacation home, full-size circuit | NEMA 14-50 outlet on a 50 A breaker | 40 A (9.6 kW) |
| Vacation home, smaller 240 V circuit | Suitable outlet on a 30 A breaker, fitted or verified by an electrician | 24 A |
The setting follows the NEC continuous-load rule: the breaker is sized at 125% of the charger current, so 40 A of charging belongs on a 50 A breaker and 24 A on a 30 A breaker. If the vacation home has no suitable outlet yet, having one fitted is a one-time electrician job. Our guide to what a NEMA 14-50 outlet is explains what to look for.
Set the Current for the House You Are In
The most common two-location mistake is carrying the setting with the charger. A unit set to 40 A at the main home must not deliver 40 A on a smaller circuit at the second property. Treat the current check as part of arriving:
- Plug in, then set the current for that house’s circuit before starting the session.
- Read the setting back on the charger’s 1.77-inch display instead of assuming it.
- Repeat the check on the first night back at the main home, in the other direction.
Whether the charger remembers its last setting between trips is a manual question — check yours rather than relying on memory, yours or the charger’s. Building the check into the arrival routine removes the question entirely.
The Travel Routine
A portable charger that lives in two places picks up wear in transit, not in use. A short routine keeps it boring:
- Leaving: unplug, coil the cable loosely, and carry the unit in its bag — not loose under luggage.
- Arriving: look over the connector pins and cable jacket before the first charge, especially after winter storage.
- Charging: the unit is IP66-rated, so a wet outdoor outlet is not a problem for the charger itself.
- Speeds: at 40 A the car charges at Level 2 rates — the U.S. DOT puts Level 2 at 10–20 miles of range per hour — so an arrival charge is normally an overnight job.
The Charger That Makes the Trip
The EV-ACS4005T 40A NACS portable charger delivers 9.6 kW from a NEMA 14-50P plug, with 16/24/32/40 A settings that let one unit match two different circuits, a 1.77-inch display for confirming the setting, IP66 sealing, and a choice of 25 or 28 ft cable. The EV-ACS3210T 32A NACS portable charger covers the same pattern at a lower current ceiling.
Frequently Asked Questions
Can I just leave the charger at the vacation home instead?
Yes, and many owners do. The trade-off is the main home then needs its own charging solution. Carrying one unit suits a weekend pattern; a charger left on site suits longer, more frequent stays.
Does the EV-ACS4005T remember its current setting between houses?
Do not count on it either way — check the manual for your unit. The safe habit is to set and read back the current at each house, every trip, as part of plugging in.
What if the vacation home only has a standard 120 V outlet?
This charger is a 240 V unit built around a NEMA 14-50 plug, so it cannot use that outlet. For a short stay, the car’s own Level 1 charging adds roughly 2–5 miles of range per hour; for regular stays, have a suitable 240 V outlet fitted — as our guide to plugging a Level 2 charger into a dryer outlet shows, the circuit behind the outlet decides.
