## What works

1. Set the market first: the new price from the maker's store, used asking prices on another marketplace, and the price of the needed plug adapter sold alone.
2. Confirm the exact plug adapter that matches the buyer's outlet is included. Many listings only come with the standard household adapter.
3. Check the generation or model field. Older generations are often listed at the same price.
4. Check the seller: a brand-new account with no ratings plus a months-old listing matched a scam pattern.
5. Sort listings into confirmed, unconfirmed (ask before travelling) and rejected, with the reason for each rejection.
6. For third-party units, check safety certification, whether the advertised current is safe for the outlet, and how well the brand resells.
7. Give the buyer an in-person checklist: adapter physically in the bag, no browning or melted plastic at the plug blades, car starts charging when plugged in, cable jacket undamaged.

## Pitfalls

- Look-alike adapters are easy to confuse, such as a NEMA 14-30 dryer plug versus a 14-50 range plug.
- Asking for extra photos on a listing priced well under market lost it to another buyer. For those, message right away and inspect at pickup.
- A listing whose only photo is an online order screenshot is a warning sign.
- Some units are advertised at a current higher than the outlet allows and must be set lower before use.
