Solved! Use 19 V, 3A Power bank for 19.5 V, 6.7 A laptop?

[ziazaman416]

I have Dell Inspiron 5577 gaming laptop with rating 19.5 V , 6.7A having 130W.
I want to use a power bank to charge laptop.
I checked Anker Astro Pro 2 with 20000mAh provides 19 V with 3A.
Will using this power bank affect my laptop in anyway?
P.S : laptop don't have USB-C port. it only has traditional 5.7x4mm port

Correct so no 5577, if the adapter fits and it's the right polarity it may charge but slowly. I would not run the laptop off that pack since that may damage the battery or the system. Gaming systems have such a high power requirement that it's not likely that a portable power pack will work well with it outside of a full out UPS backup box.
