SUNSHINE P5 Mini Smart Power Supply

A full-size supply isn't always practical for a mobile technician or a crowded bench. The SUNSHINE P5 Mini shrinks the bench supply into a mini desktop unit for phone board work.

The P5 Mini from SUNSHINE has adjustable voltage and current, a digital display, current monitoring and short-circuit protection. The listing describes it as portable and suitable for iPhone and Android phones, tablets and other devices, without stating the output range or power input.

When the P5 Mini is a good choice

• Board testing on a small or shared bench.

• Field repairs where you carry your tools.

• Spotting a short through abnormal current.

• A spare supply when the main unit fails.

What to confirm

Small supplies sometimes have lower current limits than bench units, so check the photos for its ratings and power input before relying on it for every job.

Keep its leads tidy and avoid stacking anything on top of it, since compact units have less room to shed heat. If it warms noticeably during long sessions, give it space. For a main bench that sees heavy use every day, a full-size supply may suit you better, with the P5 Mini kept as a backup.
