WYLIE WL-638 Pro DC Power Cable for iPhone and Android

Despite the listing's talk of rapid charging, the WYLIE WL-638 Pro is a DC power cable for the repair bench: it connects a phone or board to a power supply so a technician can test it. That's the job to buy it for.

The WL-638 Pro is a DC power cable from WYLIE. The listing names the iPhone 6 to 16 Pro Max and some mainstream Android models, without listing which ones, and says its connectors and insulation are built for frequent use.

When the WL-638 Pro is useful

• Powering a phone that won't start on its own battery.

• Checking current draw to find a short or a failed boot stage.

• Testing a phone while its battery is removed or damaged.

• Replacing a worn or broken bench power lead.

What to confirm

The listing doesn't describe the connectors, how many are included or how it attaches to your supply, and it frames the cable as a charging accessory. Check the photos to see what's actually supplied, especially if you rely on it for Android models.

On the bench, set the supply to the phone's battery voltage and keep a low current limit until you know the board is healthy. A cable like this doesn't protect the board by itself; the supply settings do.
