Direct answer
Chinese origin is neither a quality grade nor a complete price comparison. Some Chinese suppliers may quote competitively, but a buyer can judge value only after normalizing the exact configuration, test and document scope, Incoterms, freight, installation, software, warranty and support. Compare landed total cost for a configuration that has passed the same acceptance gates.
Normalize the quotation before comparing price
Two chargers with the same nameplate power can have materially different supplied scope.
| Quote line | Normalize these details |
|---|---|
| Electrical | Input range, output voltage/current envelope, power sharing, efficiency test point and standby behavior |
| User interface | Connector count, cable length, display, RFID, QR or payment hardware |
| Connectivity | Modem, SIM boundary, Ethernet/Wi-Fi, protocol version and CSMS integration work |
| Environment | Enclosure, temperature range, cooling method, mounting and protection options |
| Commercial | Incoterms, packaging, spares, warranty handling, software fees and excluded site work |
Test quality in stages
- Document review: exact model, drawings, bill of supplied options and applicable project evidence.
- Sample inspection: workmanship, labels, cable reach, basic protections and configured functions.
- Factory acceptance: charging sequence, output points, alarms, communications and recovery tests agreed in advance.
- Site pilot: vehicle, CSMS, payment or access workflow and local operating conditions.
- Batch acceptance: configuration traceability, inspection records and controlled handling of changes.
Compare landed total cost—not unit price
Landed TCO = equipment + options + compliance work + freight and import + site works + software/connectivity + commissioning + planned maintenance + downtime risk
Use the same period, utilization assumptions and service boundary for every bid. Record uncertain inputs as ranges rather than hiding them in a single total.
What to confirm before you buy
- Exact configuration to compare
- Incoterm and delivery location
- Software, warranty and spares scope
- Sample and FAT acceptance criteria
How to compare a SUNFULL quotation fairly
Evaluate SUNFULL on the same configuration sheet and acceptance plan used for every supplier. The quotation should identify the exact product path and project-dependent items; details such as certificates, output curves, cooling and test records should be reviewed for the proposed model during technical confirmation rather than inferred from a category page.
Request a deviation list, delivered-scope list, current technical files and the agreed sample/FAT acceptance record before comparing final cost.

DC fast charger comparison range
Use the category to compare alternative DC power and site-duty paths before selecting an exact model.
Project check: Range-level marketing copy does not replace the quoted model's data and acceptance evidence.Review this project path →Ask for a normalized quotation
Send the same configuration sheet you use for other suppliers. SUNFULL can then identify the proposed product path, included options and project-dependent evidence for a like-for-like review.
