Frequently asked questions
Can both jacks deliver 2A each?
The rating is 5 V, 2 A total output shared between the jacks. Keep the combined current within 2 A and do not assume each jack delivers the full 2 A.
How do I connect it safely to a board?
Check the polarity first: the center pin is positive. Use a plug matching the 5.5 × 2.1 mm size, and confirm the target board accepts a 5 V DC barrel input before connecting.
