Question: Why is MagSafe 1 60W/85W Adapter ( including the power supply of Thunderbolt &Cinema Display) only charging at 45W for MacBook Pro 13"&15"? 

Answer: In MagSafe 1 Adapter specification, it is 16.5V-18.5V/4.6A. However, the MacBook Pro require the 20V option. Referring to the USB C PD standard,  when using the combination of 60W/85W MagSafe 1 Adapter to MacBook Pro. It will output 15/3A 45W to charge the MacBook Pro.

Question: Why the 45W MagSafe 1 (L Sharp) or MagSafe 2 (T Sharp) is unable to charge the MacBook Pro 13” and MacBook Pro 15”?

Answer: The 45W charger output after connecting via AnyWatt, due to the power requirements of MacBook Pro (60W&87W) will go into protected mode (not output) as the power draw far exceeds its output.

Question:Why the 45W MagSafe 2 (T Sharp) can charge the New MacBook 12” and not the MagSafe 1(L Sharp)?

Answer: This is because the MagSafe 1 (L Sharp) maximum voltage is capped at 14.5V and when connected to the AnyWatt it will lose some of  this voltage and the power draw from the MacBook is higher than the output.  The MagSafe 1 will then go into protected mode.

The MagSafe 2 (T sharp) has a output of 14.8V which is enough after connecting to AnyWatt to charge the MacBook 12

Question: How to enable 85W MagSafe 2 (T Sharp) to charge at 60W?
