    FAQs about Should I insert the battery first or the power supply first

    What voltage should a power supply be plugged in first?

    If you plug the power supply in first, it is going to be at (say) 9v, until you plug in the electronic device, and then its load will bring the supply down to somewhere around its rated 5v. Note in this case, you will always be starting at a higher voltage than the rated voltage since the power supply has already plateaued at the no-load voltage.

    What order should a power supply be plugged in?

    Here it may make a slight difference what order you plug them in. If you plug the power supply in first, it is going to be at (say) 9v, until you plug in the electronic device, and then its load will bring the supply down to somewhere around its rated 5v.

    Do I need to plug a charger into AC power first?

    If you must follow a specific order, plug the charger into the AC power first, then plug the device to be charged into the charger. Why? Because I said so.

    Should a laptop charger be plugged first?

    That's one question I always asked myself but didn't have the courage / didn't bother to ask. Thinking a bit here, I would say it is better to plug it first on the power source, and then plug to the laptop. Why is that: the chargers do not output the nominal voltage as soon as it is plugged.

    What happens if you plug in a power supply last?

    If you plug in the power supply last, the inrush current will be much less extreme as you will not be shorting capacitors together. However, the output voltage of a badly designed power supply might overhoot when it gets first plugged in, subjecting the now connected laptop to a voltage transient above the allowed input voltage range.

    Can a laptop charger overhoot a power supply?

    However, the output voltage of a badly designed power supply might overhoot when it gets first plugged in, subjecting the now connected laptop to a voltage transient above the allowed input voltage range.
