A sample order is decided before the box ships. The bench-testing checklist starts when a sample arrives; what makes the sample worth testing is what you specified in writing first: the exact model and variant, the cars and supply it must work with, the documents that travel with it, and one sample for every model in a mixed range. This article covers the order itself.
Key Takeaways
- Specify model, connector, cable variant and supply side in writing — a sample of the wrong variant tests nothing.
- Send your vehicles, supply and market with the order so the sample matches your use.
- Request the documents pack with the sample; testing cannot reveal certification status.
- One sample per model, and write the production match rule into the order.
Name the Exact Variant
“A portable charger sample” is not a specification. Several EVDANCE models come in variants that change what the sample can prove, so pin each one down in the order:
| Specify in the order | Why it decides the sample’s value |
|---|---|
| Model and connector | NACS, J1772 and Type 2 models serve different cars; a sample in the wrong connector tests nothing your customers will use. |
| Cable variant | The EV-ACS4005T ships with a 25 ft or 28 ft cable. The rating label, box print and your listing all follow the variant you actually stock. |
| Supply side | The EV-ACT5006T is hard-wired or NEMA 14-50P. State which one your installers will fit. |
| Current settings as listed | The EV-ACS4005T adjusts through 16/24/32/40 A; the EV-ACS3210T through six steps from 10 to 32 A. The sample should be the setting range you will sell. |
Send Your Conditions With the Order
A sample tested against the wrong conditions produces the wrong verdict. Send the maker the facts it needs to supply the right unit and judge the result with you:
- The vehicle classes your customers drive, and the onboard charging rates they accept.
- The outlet or supply the sample will run on, including its breaker size.
- Your market, so plugs, labels and manual language match where the product will be sold.
- Any feature your channel depends on — a display, app control, RFID — named model by model, not for the range.
Request the Documents Pack With the Sample
Documents are requested, not discovered by testing. A sample session cannot tell you a model’s certification status; the paper file can. Ask for the certificates and test reports for the exact model to travel with, or ahead of, the sample — and state in the order that you will check the model number on the documents against the sample’s rating label. Which marks each listing states is mapped in our range guide to certificate ownership for private-label chargers; where a listing states no mark, the documents request is the whole answer.
One Sample Per Model — and Write the Match Rule Down
A mixed range needs a sample of every model in it. One approved portable says nothing about a wallbox, a station or an adapter. Then write the match rule into the order as your term: bulk production is to match the approved sample’s specification — the same model, variant and setting range you signed off. A sample alone cannot prove batch consistency or long-term reliability; the match rule, the production documents you agree, and your incoming inspection are the disciplines that cover those. Sample quantities, prices and lead times are quote items: EVDANCE publishes none of them, so get them in writing with the quotation. The wider ordering frame is in our OEM and private-label guide and our explainer on what sets minimum order quantities.
Choosing Which Samples to Order First
Start with the models your channel will sell first: a home portable such as the EV-ACS4005T or EV-ACS3210T, a wallbox such as the EV-ACT3204E, or a site unit such as the EV-RHDC30K-L. Once the samples land, run them through the structured checks in our guide on how to test an EV charger sample before a bulk order.
Frequently Asked Questions
Can one sample stand for the whole range?
No. Models differ in connector, settings, supply and documents. Order one sample per model you plan to stock, specified to the variant you will sell.
How many samples should I order, and what do they cost?
That is a quotation question. Sample quantities, prices and lead times are not published figures; ask for them in writing with the rest of the order terms.
The sample passes everything. Is the bulk order guaranteed to match?
A sample proves the specification can be met, not that every production unit matches it. Write the match rule into the order, agree the production documents, and inspect incoming stock against the approved sample.
