How we pick and test the gear on ReferCharge

STEP 1

We buy it and fit it ourselves

Every product recommended here was bought with our own money and installed on a real car, not summarised from listing photos. Day to day that means a 2023 Model 3 and a 2024 Model Y, both ours. If a set fought us during install, shifted once it was in, or turned out flimsier than the description implied, that is something we found out with the product in our hands rather than from a review score.

STEP 2

Both sides of both refreshes

Fitment mistakes cluster around two changes: the Model 3 Highland refresh and the Model Y Juniper refresh. Our own cars sit on the older side of each, so a friend lends us a 2025 Model 3 and a 2026 Model Y to check the newer side. On those two we verify fit and clearance rather than living with the part for months, and the guides say so rather than implying otherwise.

STEP 3

One pick per category, not a catalog

Tesla accessory listings are an ocean of near-identical products from interchangeable brands. Stocking all of them helps nobody. For each category we settle on a single item to recommend, and a category only appears here once we are confident in the pick. That is why the list is short and stays short.

STEP 4

Fitment before anything else

Tesla changed the floor pan with the 2024 Model 3 refresh, changed the interior again with the newest Model Y, and uses two different center screen sizes across the lineup. A product that fits one generation sits wrong in another. Every fitment-sensitive pick is mapped generation by generation, and the card gives you a button per version so the link lands on the set built for your car.

STEP 5

Verified on the listing, never on a search card

Search result cards routinely show a marketplace price from a different seller, or a size and capacity that is no longer available. Every product and every version button here was opened on its own listing page and checked there. Version links come from the listing's own selector rather than from guesswork, so a button labelled for your model year actually loads that model year.

STEP 6

Rejections are part of the work

Plenty of obvious candidates did not make it. Suspiciously cheap high-capacity flash drives were rejected because drives in that category commonly misreport their true size, so larger Sentry storage points at established portable SSDs instead. One popular drive family was dropped when its listed capacities turned out to be unavailable. A search for Model 3 rim protectors returned hubcap replacements rather than protectors, so we shipped the Model Y card alone rather than link the wrong product.

STEP 7

Nobody pays to be here

No brand paid for placement, sent free product, or had any say in these picks. The links are affiliate links, which means a purchase can earn us a commission at no extra cost to you, but the commission does not decide the ranking. The list is ordered by how likely a new owner is to actually want each item.

STEP 8

Checked again, and dated

Listings change: prices move, sellers disappear, generations get added. Guides carry the date they were last reviewed so you can judge for yourself how current they are. When a pick stops being the right answer it gets replaced, not quietly left up.

Do you actually own the products you recommend?

Yes. Every pick was bought with our own money and fitted to a car we had in front of us. That is the whole reason the list is short: recommending something means living with it first, which does not scale to a hundred products and is not supposed to.

Which Teslas have you tested on?

Two we own, a 2023 Model 3 and a 2024 Model Y, and two borrowed from a friend, a 2025 Model 3 and a 2026 Model Y. Between them they cover both sides of the Model 3 Highland change and the Model Y Juniper change, which are the two splits most fitment mistakes come from.

What about the versions that do not fit your cars?

Hands-on use means the generations we own and live with. On the borrowed cars we checked fit and clearance rather than running the part for months. For anything beyond that we mapped the maker's own version list, opened each listing, and confirmed the model years it is cut for. That is fitment verification rather than hands-on use, and we would rather draw that line clearly than imply we have driven every Tesla ever built.

Why is there only one pick per category?

Because a list of eight near-identical floor mat sets is not a recommendation, it is homework handed back to you. Choosing is the useful part. Where a genuine split exists, for example a stick versus a portable SSD for Sentry storage, the card gives you the options rather than pretending one answer fits everyone.

How do you make money?

One way, and it is disclosed. Product links are affiliate links, so a qualifying purchase can earn a commission at no extra cost to you. We earn nothing from the Tesla referral link itself: those links are submitted by Tesla owners and Tesla's referral credit goes to that owner, not to us. The commission never decides the ranking and it does not change what anything costs you.

What if a pick is wrong for my car?

Tell us. The contact form goes to a real inbox, and fitment corrections get priority because a wrong fitment note is the most damaging kind of error a site like this can make.
