from a DC power point of view, how much current does your device require? Look at the rating of each conductor, de-rate if necessary to give yourself margin and choose accordingly the number of power pins.The book is Electromagnetic Compatibility Engineering. For this reason, when you choose an adapter for your laptop that meets all of the three requirements : (i) Accurate output voltage and current, (ii) Exact DC connector/tip size and (iii)Appropriate polarity.There's a great book from Henry Ott that covers this - unfortunately I'm on vacation so I can't take a picture of the relevant diagram. Inaccurate voltage and current (mAh) supply may cause of laptop’s performance and unstable voltage & current (mAh) will damage your laptop’s motherboard, battery life and other integrated electronics parts. So, please be careful to buy this device from the market before ensuring the accurate output DC capacity (mAh) which is mentioned back side of your laptop. Safeguard : AC Adapter is the vital device for your valuable laptop. Note: Please be sure about DC accurate output (such as : 16.5-18.5V –4.6A, 85W) & DC connector type (such as : MagSafe 1) before ordering.Ĭaution : MagSafe 1, MagSafe 2 and USB Type “C” are not same, Please mind What you are ordering.
