    Default Geeks and Engineers help me out.

    Hello, my laptop has a 5.5mm DC port for the charger. I want to buy a power bank. Now, I found this cable online:

    http://www.amazon.com/StarTech-com-U...le+to+5.5mm+dc

    I want to buy this and use it with 10000mAh regular USB power banks. Laptop's battery is 4400mAh so 10000mAh should charge it ok. Now the question is adapter volt in 19V and the port is only 5V. I know charge will be slower on Power Bank, but it will work right? I have no idea about these stuff since commerce student.

    EDIT: Cable is only 5V.

    It'll be so slow that it'll almost be unusable, so no, it isn't really going to work.

    Besides, you risk damage to your laptop's voltage transponders feeding 5v to a 19v rated port, not to mention your powerbank probably produces nowhere near the amount of amperage the laptop actually needs to charge up.

    It's fine when it's .2A for a phone, but lappies are kinda in a higher range.


    My advice? Buy another battery, and a generic 19V charger for said battery -- then take it with you when you go out. Or you could look into one of those ultrabooks with 12 hours or so of battery life in one go, if budget permits.

    I guess I have no other option.
