Review on πŸ”Œ AC/DC Switching Power Adapter with Adjustable Variable Voltage DC5525 Power Supply - 4-24V 2A 48W Speed Control Volt for Electric Fan, Drill Motor, Speed Controller, Arduino by Joseph Adaymiln

Revainrating 1 out of 5

Very inaccurate for power converter

Purchased to connect 3V battery powered smoke alarms to the mains. Revain's description says 3 to 20V / Description printed on PS says 3 to 24V. However, the voltage can only be adjusted from 4 to 24V depending on the reading and measuring with a multimeter, the 4V shown is actually 3 .95v

Pros
  • Rugged, easy-to-use, built-in LED displays real-time voltage to help you monitor real-time charging status.
Cons
  • Not all will fit
