Anybody use an external battery pack?

As per the title, anyone has used external battery pack for charging/extending laptop battery time?

 

External batteries are not designed for the high power draw of notebooks. Using one risks damage to both the battery pack and your computer.

So there isn't a method which can be used to charge a laptop safely without a plug(mains)
Is there any then please elaborate

 

Not really. As @saturnotaku mentioned, your average external battery is not designed to power a laptop. They are for lower-draw devices like phones and tablets. There are some specifically made for laptops, but even those seem to be for lower draw laptops/ultrabooks and won't do well with a gaming laptop.

 

Hmm there should be swappable batteries in the laptop one finish 2nd one on the go

 

Not hot-swappable, but some higher end models do still come with removable batteries I believe.

 

Any examples mate?

 

The P775DM comes to mind. Not the biggest battery ever, but still removable.

 

Not sure about nowadays but back in the days there were a few models that used an optical bay that could be used for a second battery. The Alienware Area-51 m15x had one as did a bunch of other Dells and Thinkpads.

Otherwise there are some AC powerbanks that can power some low powered laptops. It's kind of like having an external battery.

The Lenovos were the last ones that supported a battery in the ODD bay I think, but I haven't seen one in a while.

 

These are also an option. Just make sure the voltage output matches your AC adapter rating and the amperage is the same or more than your AC adapter's amp rating.

Thanks for posting that. I haven't seen those before.

 

There are few machines that can be configured with hot-swappable main batteries (Fujitsu T937, some Panasonics), and quite some which have easily replaceable batteries. ODD batteries also ain't totally extinct yet, but since the move towards 9.5mm ODDs their capacity became too small to bother, it's usually more proficient to purchase an extra main battery.

 

Any recommendations for p870km1 from HIDEVOLUTION

 

That wouldn't work for a gaming notebook (those big 200W+ adapters).

But for devices with hybrid graphics where you can completely turn off the discrete GPU, wouldn't it be possible to calculate teh maximum power draw in stress testing using iGPU (which should be less than 100W), and get a suitable bank for only hybrid MODE

 

this one seems good for upto 90W power draw: https://abyone.net/index.php?route=product/product&product_id=116
