On a road trip, the EVDANCE EV-ACS4005T turns a 50-amp RV site into your overnight charger. It plugs into the NEMA 14-50 outlet on 50-amp hookup pedestals, and its four settings — 16, 24, 32 and 40 A — let it match the site instead of tripping it. Two limits shape every stop: the park’s permission, and a plug that fits a 14-50 outlet only.
Key Takeaways
- Book 50-amp full-hookup sites: that is where the NEMA 14-50 outlet lives.
- Ask the park about EV charging when booking — permission and any electricity charge are the park’s call.
- Use the 16–40 A settings to share the pedestal with the RV instead of tripping its breaker.
- A TT-30 site cannot take this unit’s plug; fall back to the car’s cord or a public charger.
Book the Site This Charger Needs
The unit’s plug is a NEMA 14-50P, so the site to book is a 50-amp full-hookup site — that is where the matching 240 V outlet lives. When you book, say the EV will charge at the pedestal and ask whether the park allows it — policies differ park by park. If a park says no, plan a public session instead — our guide to where to find EV charging stations covers the options.
The other common pedestal outlet, the TT-30, is a 120 V RV outlet. This charger’s plug does not fit it. On a 30-amp site your fallback is the car’s own standard cord at Level 1 pace, or a public charger nearby. Do not improvise adapters between outlet types; use only an adapter made for EV charging, and check with the charger manufacturer first.
Match the Four Settings to the Pedestal
Charging is a continuous load, so a charger should draw no more than 80% of the breaker’s rating. The pedestal’s breaker also feeds the RV itself:
| Situation at the site | Setting on the EV-ACS4005T | Why |
|---|---|---|
| 50-amp pedestal, EV is the main load | 40 A | 80% of the 50 A breaker: the unit’s full 9.6 kW |
| 50-amp pedestal shared with the RV’s air conditioning | 32 A or 24 A | Leaves headroom for the RV’s own loads |
| Older pedestal, unknown condition | 24 A or 16 A for the first session | A gentler first draw on an unknown pedestal |
| 30-amp TT-30 site only | Not this unit | The 14-50 plug does not fit a 120 V TT-30 outlet |
How outlet type and setting decide real speed is covered in how portable EV chargers work. At full setting, Level 2 adds roughly 10–20 miles of range per hour (U.S. DOT) — do the arithmetic against your own daily miles.
At the Site: Reach, Weather and the Overnight Session
- Park for the cable. The 25 or 28 ft cable decides which way the car faces: pedestal on the charge-port side keeps the cable off the ground and out of walkways.
- Keep connections up and dry. The unit is IP66-sealed against rain and dust; the plug connections still deserve care — keep them out of puddles and standing water.
- Step down in the evening. If the RV’s air conditioner or heater starts cycling, drop a setting rather than finding the breaker’s limit at midnight.
- Check once before bed. Confirm the session is running at the setting you chose, then let it finish.
Why This Unit Suits the Trip
The EV-ACS4005T 40A NACS portable charger earns its trunk space because one unit covers both ends of the trip: full-speed charging on your own 14-50 outlet at home, then the same outlet type at 50-amp sites along the route, with setting steps to share a pedestal politely. Its display confirms the session at a glance, which matters when the “garage” is a gravel pad. A finer-grained alternative for older or shared pedestals is the EV-ACS3210T 32A portable charger, with six steps from 10 to 32 A. Both are IP66-rated; what the IP codes mean in practice is in our guide to portable charger waterproofing.
Frequently Asked Questions
Will the park charge me extra for the electricity?
Policies differ — some parks include hookup electricity in the site fee, others treat EV charging separately. There is no standard rule, so ask when you book.
Can I charge if my site only has a TT-30 outlet?
Not with this charger: its plug is a NEMA 14-50P and the TT-30 is a 120 V outlet of a different shape. Use the car’s own cord for a slow overnight top-up, or charge at a public station before you arrive.
What if the pedestal breaker trips overnight?
Lower the setting before the next session and tell the office — repeated trips mean the combined load is too high for that site. A stepped-down session that finishes beats a full-rate one that trips.
