FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "2.5mm * 0.7mm" mean? This is the size of the DC tip: 2.5mm is the outer diameter (OD) and 0.7mm is the inner diameter (ID).

2. Is this cable compatible with 12V devices? No, this is a direct pass-through cable intended for 5V USB power sources.

3. What makes "National Standard Copper" different? It refers to standardized high-purity copper that ensures lower resistance and higher current carrying capacity.

4. Can it handle more than 1A of current? Yes, it is rated to safely carry currents exceeding 1A without overheating.

5. Will this work with my specific tablet? Please measure your tablet's DC port; 2.5mm x 0.7mm is a very common size for older 7-inch and 10-inch tablets.

6. Can I use this for data transfer? No, this is a dedicated power/charging cable and does not contain data lines.

7. Is the connector "center-positive"? Yes, standard USB to DC cables are wired center-positive (5V on the inner pin, Ground on the outer sleeve).

8. How long is 0.8 meters? It is approximately 80 centimeters or 2.6 feet.

9. Can I plug this into a computer USB port? Yes, but remember that most computer USB 2.0 ports are limited to 0.5A; use a wall adapter for 1A+ needs.

10. Is the cable jacket durable? Yes, it uses a reinforced PVC jacket to withstand bending and daily wear.

11. Why is my device charging slowly? Ensure your USB power source (adapter or power bank) is capable of outputting the current your device requires.

12. Does it fit the Nintendo DS? No, the original DS/DS Lite uses proprietary connectors.

13. Can it power a Raspberry Pi? Only if your Pi setup uses a 2.5mm x 0.7mm DC jack (standard Pi uses Micro-USB or USB-C).

14. What is the color of the cable? It is standard matte black.

15. Does the tip have a "yellow" or "black" end? This depends on the batch, but the dimensions remain 2.5mm x 0.7mm.

16. Is it compatible with 5V LED strips? Yes, if the strip uses a 2.5mm x 0.7mm barrel connector.

17. Can I use this with a 9V USB step-up converter? Only if the converter has the correct female USB-A output.

18. Is it safe to leave plugged in? Yes, provided the power source is regulated and the device is in good condition.

19. What is the weight of the cable? It is very lightweight, approximately 22 grams.
