So is this a portable battery for laptops or just a power brick?
Laptop Power Supply… unlike a power pack for a mobile phone
What does that even mean? Is it the charging brick then?
This is an AC to DC power supply unit, it does not store power and it is not a 'power bank'.
Your laptop already has a AC adapter unit, this is a 3rd party replacement.
is it even possible to get a battery pack that can charge a flat laptop battery? that would be affordable and not the size of a generator?
so you are after a external charger that can recharge a laptop battery without being inserted into a laptop??
yeah they have to be custom made though. So they are a bit pricey

I recommend Amazon for these kind of things. The aussie market is too small.

and kogan had this at one point, but no idea when they dumped it:

Use one of these in conjunction with a 12v 7ah SLA battery for $30, or an equivalent 3S lipo battery. Given it is capable of a 12v input then you're set!
fun fact: laptops are not all that fussy about the input voltage. A few volts this way or that will still work, and not let out the magic smoke.
dumb fact : they are fussy when it comes to polarity !
True, tho it's one way to find out if you are running on white or black smoke.
oh!… like voting a new pope!?
I would imagine any smoke is not good smoke
Doesn't include Lenovo's new slim charging tip, so will need an adapter
Does it have USB-C?
Does it have USB-C?
The specs say NO. This is a laptop power supply for traditional charging.
"Voltages available: 14.5, 15, 16, 16.5, 18.5, 19, 19.5, 20V output at maximum of 90W."
Image on the site shows a standard USB-A plug, so throw a USB C adapter cable in and you're golden.

It's not designed to charge notebooks that use USB type C.
USB: 5V 2A(10W Max)
Proper USB type C charging can deliver 90W at 20V.
I would buy if it was compatible with the Surface PRO4 but nope. Original SP4 supply is $125. Ouch.
Try to go to eBay and look for used SP3 adapter. It works totally fine
I had already looked at them but when you read the feedback they all seem to be counterfeit supplies that are either electrically noisy or don't supply the rated amount of current. I don't want to use a dodgy Chinese fire hazard supply from eBay etc.
That's why i used the term "Used". Look for those who have a windows 8 sticker on the adapter.
I got tricked into buying the counterfeit one and agree they are really bad (i.e. getting really hot). I learnt my lesson.
Could anyone advise if I can use this as an adapter for my Dell XPS17? My current adaptor wires are becoming lose.
try it!….. they have 1 week return policy
For someone looking for a replacement AC adapter charger for a second hand laptop purchased - what are the key things to look for to ensure it works and won't harm said laptop?
Someone said matching up voltage? WHat about the other 'specs' of laptops - knowing nothing about the electronics I am just wondering what figures or items to match up to know that the replacement adapter purchased is compatible? voltages? watts? anything else that is common lingo in describing the items?
different laptops have different specs, it is impossible to say the same thing for every make of laptop out there.
if your laptop is not mentioned in the compatibility list, it's either trial and error.
Macbooks in particular, have a smart charger with a microprocessor that regulates power flow. They cannot be used with 3rd part chargers in a safe way because the control IC is there to monitor changes in current and temperature, and it stops charging if it senses over-temperature or over-current issues. The control IC is not found in a 3rd party charger because it's apple's proprietary technology.
