As a mobile phone data cables manufacturer and exporter, many of my customers asked me the same question – how can I check the quality of the mobile phone data cables that I purchased?some of other guys may have the same question in mind. Well, Let me show you the steps.
1. The cable is wearable or not?
You should check this to avoid potential problem may occur in the sales. You can take out a sample from the mass production products and twist and then straighten it. Repeated this process 3-5 times and you will get the difference. Normally it should bear 5 testings as a mininum. Of course, it is a good data cable if your testing is more than this!
2. The USB metal part or the connector part is easy to get rusty?
This helps to check the life of the data cable. You cannnnnot use a data cable always above 40 degrees with heating and dry air. The streams in the air usually will harm the metal parts. Put the testing sample in water or salty water for 8 hours. It is the best without any signs of rust. It is still good to see some small points because you will not put a data cable in water when in real usage.
3. Put-in and take-out times of the charger port and the USB are both important for you.
This is a technical check. You cannot plug the USB cable till it is broken. but you can try 50-100 times so see the result. Just put the charger port in and take it out. Repeat 50-100 times and you will find that some of them broken or worn if it is not good. A normal charging cable would bear more than 500 tests of put-in and take-out.
4. Cable length
It is simple. Just measure that.
5. The data cable carrying currency
This is the most important thing for a data cable no matter it is just a charging cable or a cable with data transmission. The currency means that the mobile phone charging speed. More currency can pass through the data cable and the charging would be more efficient and faster on condition the mobile phone charger can supply enough currency for the phone.
Simple way is to use a LED meter to see the charging currency directly. The more of the numbers the good the data cable. You can see directly from the number on the screens of the tester.
If we do not have a LED tester meter with us, we can also cut the data cable in half and see the inside metal wire. You know the specifications and you can easily know the quality of the data cables.
We can also test that with a mobile phone. Your phone is fully charged in 2 hours with the original charger. It is not bad to get a 2.2 hours of full charge with the same phone and charger but with new data cable. But, it is horrible to get 3 hours or more under the same condition!
6. IC life inside the charging connector
We take iphone lightning data cables for example. The longer using life for the data cable also depends on the inside IC. Some data cable ICs are not purchased from original maker. This means that it is cracked or copied. Some good ICs will experience several generations of the software update. The cheep ones will be ended just one update of the software.
