Using this Amass charging cable is easy. Just plug the XT60 male plug into the appropriate power source and the two XT60 female plugs into the devices you want to charge simultaneously. This allows for parallel charging, saving you time. When using, make sure the connections are secure to avoid power interruptions. Also, don't expose the cable to extreme temperatures or moisture as it can damage the cable. To maintain it, keep it clean and free from dirt. If not in use, store it in a dry and cool place. This way, your cable will last a long time and keep working well for your charging needs.
