Recommendations

Use a high-quality USB-C cable rated for power delivery to ensure reliable charging. Verify that your laptop or device accepts 45W or less from a USB-C PD source; devices that require higher wattage may charge slowly or not charge while under heavy load. Avoid exposing the adapter to liquids, extreme temperatures or prolonged direct sunlight, and unplug the unit during electrical storms to reduce risk of damage.
