Our verdict
Memory presets change how a bench supply feels to use: 3.3V, 5V and 12V become a button press rather than a careful dial adjustment, and the key lock stops an elbow from changing a setting mid-test. For a repair bench or anyone who powers the same circuits repeatedly, those conveniences are worth the small premium.

Getting started with the WANPTEK TPS-C 3010H Bench Power Supply with Memory
Store the voltages you use most — typically 3.3V, 5V and 12V, each with a sensible current limit — as presets on day one. Enable the key lock once a test is running. With the output switch, make it a habit to switch the output off before touching the wiring, then back on to resume.
Who it's for
Repair benches and makers who switch between the same voltages often.

WANPTEK TPS-C 3010H Bench Power Supply with Memory: common questions
What are memory presets on a power supply?
Stored combinations of voltage and current limit that you can recall with a button. They save time and reduce setting mistakes when you regularly power circuits at standard voltages.
What does the key lock do?
It disables the front-panel controls so a setting cannot be changed accidentally during a test — useful on a busy bench.
Do I need presets as a beginner?
Not strictly. They become valuable once you regularly work with a few standard voltages. A simpler supply with a current limit covers the essentials for learning.
