Frequently Asked Questions About USB Charging Cables
Insights into custom manufacturing, power specifications, and cable design
01What is the difference between a charging cable and a data cable?
Charging-only cables are designed solely for power delivery and do not have data pins. They are lower cost and ideal for applications where data transfer is not needed (public charging stations, hotel rooms, fixed installations). Data cables support both charging and data transfer and are the standard for retail products.
02What wire gauge should I choose for my charging cable?
Wire gauge (AWG) determines how much current the cable can carry. For standard 1A-2A charging, 28AWG is sufficient. For 3A fast charging, 24AWG is recommended. For 5A/100W charging, 22AWG or thicker is best, especially for longer cables. We can help you select the right gauge based on your power requirements and cable length.
03What is the maximum length for a USB charging cable?
For reliable charging, we recommend up to 3 meters for standard cables. For longer runs (5m+), we use thicker wire gauges (20AWG-22AWG) to minimize voltage drop. We can design custom-length cables for specific installations.
04What is an E-marker chip and do I need it?
An E-marker chip is required for 5A/100W+ charging cables. It enables safe power negotiation between the charger and device. For standard 3A/60W charging, E-marker chips are optional but can be included for compatibility.
05Can I get a charging-only cable without data pins?
Yes, we manufacture charging-only cables for applications where data transfer is not needed. These are ideal for public charging stations, hotel rooms, and fixed installations. They are more cost-effective than full-feature data cables.
06Can I get a charging cable with my company logo?
Absolutely. We offer custom logo printing via laser engraving on metal connectors or pad printing on molded housings. Minimum order applies. Contact us with your logo artwork for a quote.
07What is the minimum order quantity (MOQ) for custom charging cables?
For logo printing on stock cables, MOQ is 500 pieces. For full-feature custom designs (custom length, color, packaging), MOQ is typically 1000 pieces. Low MOQ options available for startups.
08How long does it take to get a sample?
Stock samples are available within 3-5 days. Custom samples with your logo and specifications take 7-10 days. Sample costs are typically deducted from your mass production order.
09Do you offer PD fast charging cables?
Yes, we offer PD charging cables up to 240W. All our PD cables include E-marker chips and are tested to deliver the advertised power.
10What is the warranty on your charging cables?
We offer a 12-month warranty on all USB charging cables. For custom OEM projects, warranty terms can be negotiated based on your requirements.
11Can you make DC power cables for my specific application?
Yes, we manufacture DC power cables with barrel connectors (5.5x2.1mm, 5.5x2.5mm, 3.5x1.35mm) or bare wire terminations. Thicker wire gauges available for higher current applications.
12What payment terms do you accept?
We accept T/T bank transfer, L/C, and PayPal for sample orders. For mass production, typically 30% deposit and 70% balance before shipment.
