Where the load actually goes
A phone case with a built-in stand is a mechanical product built around a specific phone: the hinge and the kickstand carry the phone's weight, and the case — not the stand — is what has to hold. That means the case structure, the material near the hinge and the fit around the camera cutout all matter. The mechanical test is a hinge test: our SK7 shaft is tested to 6,000+ open-close cycles.
A separate magnetic holder works the other way round. The load goes from the phone's back panel through the magnets, and the case — if there is one — only sits in between. That is why case thickness is the variable that matters, and why the OX-3 has magnets on both faces: the outer face grips the phone or case, the inner face grips a magnetic car mount or stand, so a thick case does not have to be removed.
For a buyer, the practical question is which one you are actually selling: a case that happens to stand up, or a holder that works with the case your customer already owns.
What each route does to your stock
A case-with-stand has to be built for a phone model, so every model you support is another SKU — and every SKU is inventory you carry, in colours, with a return risk that cannot be swapped across models.
A separate magnetic holder is a common part: one model covers a whole range of phones. That is why MOQ 50 pcs per model is workable for a first order, and why an accessory line can be launched without committing to a case mould for every model.
| Decision point | Case with a built-in stand | Separate magnetic holder |
|---|---|---|
| Where the load goes | Through the case and hinge | Through the magnets to the phone's back |
| SKU structure | One SKU per phone model | One model covers many phones |
| Minimum order | 50 pcs per model — each model counts separately | 50 pcs per model |
| Thick case on the phone | Not applicable, the case is the product | Set by the magnet design; OX-3 is double-sided for this |
| What fails first | Hinge and case material | Magnet strength and the adhesion face |
| Buying cycle | Follows phone launches | Independent of phone launches, repeats on its own |
When the honest answer is to sell both
Three situations. First: a phone-case brand that wants an accessory line without opening a new mould for every model. Second: a bundle — case plus holder sold as one retail or gift pack, which is the route promotional and corporate buyers take. Third: a distributor whose customers keep asking for the same product in both forms.
Where a bundle is the plan, the bundle is a packaging project as much as a product project: the two parts have to be packed together, and the box has to survive the trip.
What we will not do is encourage a case mould for a phone model with no proven demand. A holder orders at 50 pcs per model because it runs on tooling that already exists — 21 models are already on tooling and we run 100+ product types — so a small first order opens nothing new.
Test the decision on a sample first
Pick the model, order the sample, then test it on a real phone with the case your customers actually use — not a bare phone on a desk. Samples take 7-10 working days, mass production is 7-12 days after the sample is approved, and packing and final inspection add 3-5 days. FOB Shenzhen.
Our own two products for this comparison: the CX-5 ring holder (aluminium alloy + N52, 58 × 3.8 mm, 18 g, 360° rotation) and the OX-3 double-sided magnetic holder (aluminium alloy + N52, 58 × 4.5 mm, 25 g, magnets on both faces, N52 · 4100 GS).

Frequently asked questions
Will a separate magnetic holder hold through a thick case?
That is what the double-sided design is for: on the OX-3 the outer face grips the case and the inner face grips the mount, so the case can stay on the phone. How much a specific case reduces the grip depends on its thickness and material, so we test it on the sample — we do not publish a case-thickness number we have not measured.
What is the minimum order for a case with a built-in stand?
50 pcs per model, and each phone model counts separately, because each model is its own mould and its own SKU.
Can the phone still be charged wirelessly with a holder attached?
Magnetic alignment is what makes wireless charging work, so the mounting position matters more than the holder itself. Test your exact combination on the sample; we will not claim it works with every charger.
Which one has the lower return rate?
We do not publish a return-rate figure, because we do not have a verified one. What we can state is the process: 4 QC staff across 2 lines, and 3-5 days for packing and final inspection on every order.
What do your patents cover?
Eight granted CNIPA patents: five design patents and three utility models covering rotating, folding and pressure-relief mechanisms, plus registered trademark no. 80143576 (Class 9) and copyright registration 国作登字-2024-F-00271084. We send the numbers so you can query each one yourself.
