Compare car wireless charger quotes using the same bill of supply, not the headline wattage alone. Ask each supplier to identify the charger model, cooling configuration, vehicle mount, power adapter, cable, packaging and sample approval scope. Shinestone is an OEM/ODM wireless charger manufacturer and supplier; the two catalogue examples below show why a 15W clamping model and a 25W semiconductor-cooled model need different sourcing briefs.
For US importers, accessory companies and promotional-product buyers, this approach makes the quotation specific enough to review before committing to samples. It does not require assuming a price, minimum order quantity or delivery date that has not been quoted.
What should a comparable car wireless charger quote include?
| Quote line | What to specify | What to clarify |
|---|---|---|
| Charging unit | Exact model and hardware configuration | Is the price for the head only or a complete kit? |
| Cooling | Semiconductor module, fan, both, or another stated arrangement | Which cooling components are included in the quoted sample? |
| Vehicle mount | Vent clip, suction arm or other selected installation | Are the clip, arm, ball joint and installation accessories included? |
| Power adapter and cable | Adapter output profiles, cable connectors and length | Are they included, optional or supplied by the buyer? |
| Decoration and packaging | Logo location, artwork, box format and included instructions | Are setup, sample and packaging charges separate? |
| Commercial basis | Order quantity, destination and agreed delivery basis | Which freight costs and other charges does this specific quote include? |
Keep each line visible in the supplier comparison. A lower unit figure for a charging head cannot be compared directly with a kit that includes an adapter, mounting arm and printed box. Ask for the missing items to be priced or explicitly excluded.
Two real model examples: specify the difference before requesting a price
| Listed feature | SST-WXC2762 | SST-WXC2701 |
|---|---|---|
| Wireless output | 25W maximum | 15W maximum |
| Key configuration | Semiconductor cooling plus fan-assisted heat dissipation | Clamping cradle with one-touch release |
| Power-source specification | USB-C input; supplied specification lists a PD 45W source | Type-C input; DC 5V/2A or 9V/2A |
| Mechanical brief | 90° rotation and retractable bottom support; confirm selected mounting accessories | Photographed version has an adjustable suction-cup mounting arm |
These are model specifications, not a side-by-side charging test. Maximum wireless output is not guaranteed for every phone. Confirm the receiving device, case, adapter and operating conditions with the selected sample.
For SST-WXC2762 semiconductor-cooled car wireless chargers, put both semiconductor cooling and the fan in the RFQ. A description that says only “cooled” leaves the configuration unclear. For SST-WXC2701 one-touch release car wireless chargers, identify the photographed suction-mount version and confirm what the kit includes. A required power-source rating does not by itself mean the adapter is included in the price.
Separate protocol claims from model-matched certification evidence
If your project requires Qi certification, ask for the exact product’s registration information and check it in the Wireless Power Consortium product database. The WPC explains that the certificate link should identify the same physical product, brand, product name and type number. See its official certification verification guidance.
A catalogue statement of protocol support is not a substitute for that evidence. Certification IDs and a Qi2.2 claim are not asserted here for either example. Agree on the documentation required for your final configuration before approving product or packaging claims.
A short RFQ brief buyers can copy
We are reviewing [model] for the US market. Please quote [quantity] units and identify the charging head, cooling components, vehicle mount, power adapter and cable included. Our target phones and cases are [list]. We need [logo location] and [packaging brief], delivered to [destination] on [requested date]. Please confirm available customization, sample charges, sample timing, MOQ, production timing, delivery basis and model-matched documents. List any items or charges excluded from the quote.
Use the same brief for every supplier. When a component changes between sample review and the purchase order, update the bill of supply and approval record. Our sample-to-production change-control guide explains how to keep configuration changes visible.
Request a model-specific quote from Shinestone
Send the model, target devices, intended mounting position, quantity and packaging brief. Shinestone will review the selected sample configuration and available OEM/ODM options before confirming pricing, MOQ and timing. If you are still selecting the installation, read the vent-versus-suction mounting guide and browse the car wireless charger range.

Buyer questions
Does a 25W charger quote always include a suitable car adapter?
No. Ask the supplier to list the adapter separately or mark it as included. For SST-WXC2762, the technical specification lists a PD 45W power source; the actual kit contents must still be confirmed in the quotation.
Can I compare the two models only by their maximum wattage?
No. Their cooling, input requirements, phone support and selected mounting arrangements differ. Choose the intended configuration and evaluate it with your target phone and case before comparing complete quotations.
Can logo, packaging, MOQ and lead time be assumed from a catalogue page?
No. Include the artwork, quantity and destination in the inquiry. Those commercial and customization details need confirmation for the selected model and project.
