About Shenzhen Cool Line Technology Co., Ltd. - Computer Cables Supplier in China

Based in China, Shenzhen Cool Line Technology Co., Ltd. lists ten active products in its online catalogue. All items are variations of USB cables, ranging from metallic nylon‑braided constructions to leather‑braided and zinc‑alloy housings, with several models incorporating LED indicator lights or magnetic connectors. The product titles include Metallic Nylon Braided USB Cable, Magnetic USB Cable (USB‑A to Lightning), Jeans Stitched USB Cable, Zinc Alloy USB Cable, TPE USB Cable with LED Indicator Light, Metal Spring USB Cable (USB‑A to Lightning), Leather Braided USB Cable, USB Cable with LED Indicator Light, Zinc Alloy USB Cable with LED Indicator Light, and TPE USB Cable (USB‑A to Lightning).

The supplier’s top categories are recorded as Computer Cables, Electric Lamps, Tubes, Bulbs, Lights & Light Fittings, and Agriculture, but the current catalogue only details computer‑cable products. No other product types are enumerated in the supplied data, so the description is limited to the ten USB cable variants. The catalogue does not specify dimensions, data‑transfer standards, or connector types beyond the USB‑A to Lightning pairing, leaving those details to be clarified with the supplier.

Product Range and Specialties of Shenzhen Cool Line Technology Co., Ltd.

Shenzhen Cool Line’s USB cable portfolio covers a range of material choices that are common in the global market. Metallic nylon braiding provides abrasion resistance and a premium feel, while TPE (thermoplastic elastomer) offers flexibility and weather‑proofing; leather braiding adds a luxury aesthetic, and zinc‑alloy housings improve connector durability. LED indicator versions typically embed a low‑current diode that flashes on power or data transmission, and magnetic connectors are used for quick‑release applications. In the broader industry, USB cables are produced to USB 2.0 (480 Mbps) or USB 3.0/3.1 (5 - 10 Gbps) specifications, using 28‑AWG or 24‑AWG conductors, with shielding such as foil or braided copper to reduce EMI. Standard lengths range from 0.5 m to 2 m, and connectors are often gold‑plated to improve conductivity. Buyers usually look for compliance with CE, RoHS, FCC or UL standards, and may request data‑sheet details on voltage rating (typically 5 V, 1.5 - 2 A), insulation resistance, and bend‑test results.

Trade and Export Information - Shenzhen Cool Line Technology Co., Ltd.

China remains the world’s largest exporter of consumer‑grade USB cables, shipping the majority of units in 20‑ft or 40‑ft containers. Major import markets include the United States, the European Union, Japan and South‑East Asian nations, where electronics OEMs and aftermarket distributors source bulk volumes. Export shipments are classified under HS Chapter 85, heading 8544 for “Insulated (including individually) wires, cables and other conductors,” with sub‑headings for data‑transmission cables. Buyers typically request CE marking for the EU, FCC certification for the US, and RoHS compliance to confirm restriction of hazardous substances. Packaging conventions involve poly‑bagging of individual cables, then stacking in cartons of 500 - 1,000 units, with outer palletization for container loading. Freight terms most often use CIF or FOB, and customs inspections frequently verify the presence of safety test reports and conformity certificates.

Sourcing from Shenzhen Cool Line Technology Co., Ltd. - Buyer Guidance

When evaluating Shenzhen Cool Line’s USB cables, buyers should request a product data sheet that lists conductor gauge, shielding type, rated current, voltage, and LED power consumption. Test reports for electrical safety (e.g., IEC 60950‑1 or IEC 62368‑1), tensile strength of the braid, and environmental durability (temperature cycling, humidity resistance) are standard documents to verify before placing an order. Samples should be examined for connector fit (USB‑A to Lightning), LED brightness, and material finish, especially for leather‑braided or metallic‑braided versions. Typical minimum order quantities for custom‑label or bulk purchases range from 500 to 1,000 units, with lead times of 20‑35 working days after artwork approval. Confirm that the supplier can provide CE, RoHS and FCC test certificates, and ask whether third‑party inspection (e.g., SGS or Bureau Veritas) is available prior to shipment.

What types of USB cables does Shenzhen Cool Line offer?

The catalogue lists ten variants, including metallic nylon‑braided, leather‑braided, zinc‑alloy, TPE, and jeans‑stitched cables, with several models featuring LED indicator lights or magnetic connectors for USB‑A to Lightning connections.

Are the USB cables compatible with USB 2.0 or USB 3.0 standards?

The product titles do not specify the data‑transfer standard; buyers should request the exact USB version and corresponding data‑rate (e.g., 480 Mbps for USB 2.0 or 5 Gbps for USB 3.0) from the supplier.

What certifications should I ask for before purchasing?

Typical certifications for USB cables include CE marking for the EU, FCC compliance for the US, RoHS declaration, and UL or IEC safety test reports. Verify that the supplier can provide the relevant certificates for each cable variant.

What is the usual minimum order quantity (MOQ) for these cables?

Based on industry practice for custom‑branded USB cables, MOQs generally start at 500 units per SKU, though the exact figure should be confirmed with the supplier for each specific model.

How long does it take to produce and ship an order?

Lead times are commonly 20‑35 working days after final design approval and receipt of any branding artwork, followed by container loading under standard CIF or FOB terms.

What packaging formats are used for shipment?

Cables are typically poly‑bagged and packed in cartons of 500 - 1,000 pieces, with pallets prepared for 20‑ft or 40‑ft container loading. Outer cartons include product codes and country‑of‑origin markings.

Can I receive a sample before placing a bulk order?

Yes, suppliers usually provide a single‑unit sample or a small sample pack for evaluation of connector fit, LED function, braid quality, and overall build, with sample costs often refundable upon larger order placement.

What documentation is needed for customs clearance?

Customs authorities usually require a commercial invoice, packing list, certificate of origin, and any applicable conformity certificates (CE, RoHS, FCC). An inspection certificate from a recognized third‑party agency can also facilitate clearance.
