Review on πŸ’‘ DAOKI 5PCS XL6009 DC-DC Adjustable Step-up Boost Power Converter Module as a Replacement for LM2577 by Flocka Parsons

Revainrating 1 out of 5

Good news: Very low price Bad news

Good news: Very low price Bad news: None of the devices were as advertised. 9.0VDC at 0.1A output. They each required at least 3.7 VDC input for 9 VDC output, as confirmed by my variable DC power supply. It worked perfectly with the A123 twin cell battery pack at 6.6VDC input. Pieces, I keep them.

Pros
  • Inspires confidence
Cons
  • Damaged
