Cable for charging. However, they are not suitable for charging. In testing, I saw a 0.45V drop across the cables when loaded with 1A. Assuming the power supply doesn't drop below 5V, you will be under the USB voltage specification (4.4V) of just over 1 amps drop. Regardless of the specification, these cables draw about half a watt of power when loaded with 1 amp. The build quality in production is normal. Not good. It's pretty obvious that these are cheap cables. But that's to be expected for…
