SUNSHINE P1 Pro Max Smart Regulated Power Supply

"Smart" on a power supply can mean anything from saved presets to automatic short detection. The SUNSHINE P1 Pro Max is sold as a smart regulated supply for phone board work, but the listing doesn't explain which smart features it has.

The P1 Pro Max from SUNSHINE offers adjustable voltage and current, a digital display, real-time current monitoring and short-circuit and overload protection. It's listed for iPhone and Android phones, tablets and other electronics. The output range isn't stated.

When the P1 Pro Max is useful

• Powering a dead board for diagnosis.

• Spotting abnormal current from a short.

• Chip-level repair that needs steady power.

• A bench upgrade from a basic or failing supply.

Questions to answer first

Check the photos for the display, controls and output terminals, and confirm whether it has presets, a current-curve display or an automatic cut-off, since the listing doesn't say. Compare it with the other SUNSHINE supplies we list before choosing.

Whatever the features, the basics remain: check the settings before connecting a board, start with a sensible current limit and watch the reading as you power up.
