Frequently Asked Questions (FAQ)
Q.
Is it a real 40 Gbps USB4 or just rebranded USB 3.2?
Certified USB4 Gen 3×2 — 40 Gbps bidirectional, full Thunderbolt 4 compatible.
Q.
Can it charge at 240W?
Yes — E-Marker chip inside supports EPR 240W (48V/5A).
Q.
Where are your factories located?
We own and operate two factories: one in Zhuhai, China (since 2006) and one in Bình Dương, Vietnam (since 2019). Both are owned by Farreach — no third-party outsourcing.
Q.
What certifications do your factories hold?
Both factories are ISO 9001:2015, ISO 14001, BSCI, and SEDEX 4-Pillar audited. All cables are UL/ETL, RoHS, REACH, CE, and FCC certified.
Q.
Can I visit the factory or do a factory audit?
Yes, always welcome. We host 30+ client audits every year. Just email sale-9@farreach-electronic.com with your preferred dates and we’ll arrange everything (including hotel pickup if needed).
Q.
What is your production capacity?
China factory: 350k cables/month
Vietnam factory: 500k cables/month
Total: over 850k cables per month, with room to scale up 30% in peak season.
Q.
How do you ensure consistent quality between the China and Vietnam factories?
Our Vietnam factory mainly serves US clients while Zhuhai serves the rest. Both factories run similar BOMs and SOPs. Raw material batches (OFC copper, PVC compounds, fiber spools) are pre-approved centrally in Zhuhai and shipped with sealed QC certificates. Clients who audit both sites routinely comment they cannot tell which factory the product came from. This is deliberate: one Farreach standard, two roofs.
