Portable Battery Bank for Laptop

[JoshCoopster]

Hi all,

 

I'm looking at getting a portable power bank to recharge my laptop whilst away from the mains.  I currently have a MSI ge72 6qd but am looking to upgrade "soonish" to a MSI GS75 or Razerblade Pro 17. 

 

Any advice on how many watts I'd need to get a decent rate of recharge / life extension? 

 

Currently looking at something like: https://www.amazon.co.uk/dp/B07WV2WB9T/?coliid=I3IP1XTPORHSN0&colid=2EALSMIBF7KMQ&psc=1&ref_=lv_ov_lig_dp_it

How about don't use a gaming laptop if you want something with good battery life.

 

 

No but seriously if you're using this as a school laptop or something I would sell/return it and get something more reasonable, like a Thinkpad.

That battery bank won't do. It has a max output of 100W, and most gaming laptops need at least 120W.

 

If you want more battery life out of a laptop, you're going to have to tune it such as undervolting the CPU and GPU to the limit. And even then that may not buy you a lot of time.

The laptop is used for a both work in the day and as a gaming rig in the evenings - although I don't imagine gaming away from a fixed plug socket any time soon.

 

Is it not the case that the laptop will draw lower watts whilst doing less intensive tasks (such as working on word and excel) and a lower watt power supply would charge the unit - just slower?
