Omen Max 16 (16-ak0770ng) USB-C max wattage

[Freschluft]

Hey there!

I bought the Omen Max 16 (16-ak0770ng) model and am very content with it.

As I mostly use it in the office and leave the big charger at home, I wonder what the wattage limit of USB-C charging is for this particular model.

On HP's website, it is clearly stated that the AMD model supports USB PD 3.1 (EPR), just as the Omen Transcend 14. This would normally imply that, like the Transcend, it should be able to USB charge at 140w vs. Just 100w on USB PD 3.0 models.

Could you kindly answer this question?

Thanks a lot and warm regards

Hi @Freschluft 

As indicated in the service manual, 100 watts or more are required. Page 3

Maintenance and Service Guide OMEN MAX 16 inch Gaming Laptop PC Model number: 16-ak0xxx

Power delivery (100 W input

Thanks for your response. 

But my question is not about MIN wattage but MAX wattage. 

100 watts or more, great. But what does "more" indicate on the case of this very Laptop? 

[resistencia]

The power delivery indicates 100 watts. It is easier to find chargers with 100 watts of power. A USB-C charger with higher power is supported without any problems, but they are more expensive and difficult to find.

It must be a connector that supports 100 watts. Other models require a significant investment because they must have the same wattage as the charger, otherwise they will not charge.

Hi!

@resistencia, I believe this user is asking what would happen if he charged the system with a 1000W USB-C charger (in theory, if it existed). Answer is nothing different. The charger would be extremely cold, and only give out 100W. Unless the motherboard is wired to accept higher wattage, surplus is not used. Manual (given above) page 3 clearly states 100W input capabilities. This is max.

[Freschluft]

Hm this is weird because the product number of the manual is correct and I can see where you found the 100w. But on the same page, it states that this manual is for the Intel versions and for the Intel versions it also states on HPs websites PD 3.0 which is in line with the 100w. But if you go on the HP website to an AMD version, you'll find PD 3.1 (and as a downside no Thunderbolt 4) so they actually might be using different ports and motherboards (of course, after all, it's Intel vs AMD)...

Do you see what I mean? English isn't my mother tongue so I hope it's clear enough

Freschluft, looking at specs and overanalyzing them won't help you on this matter.

A  seasoned HP Expert here on the forum once told me that all that matters is if the laptop is actually sold with an HP USB-C charger. Otherwise USB-C charging might not work at all, or in the best case scenario it will be considered an auxiliary power source. Things are pretty simple here. HP seems to offer no OFFICIAL usb-c charger. Therefore, stick to the high wattage barrel charger.

Hi @TzortzisG 

Power delivery works in two ways: one is to provide more power to smartphones or monitors. Then there is the input, which, as indicated in the manual, is 100 watts in this case, which is good because, in theory, this model uses a 280 or 330-watt AC charger, making it almost impossible to find a USB-C charger with that power. So the user could, for example, find a 140-watt USB-C charger. This does not mean that it is sending 140 watts through the port, but rather that the charger has the necessary power to charge the laptop. It is more or less how a cell phone works: using a 1-watt cell phone charger is very different from using a 25-watt cell phone charger.

As a curious detail, I have two iPhones, one with a battery at 70% capacity and the other at 94% capacity.

The first one requires a 25-watt charger to charge; if I use less, it won't charge because the battery needs to be replaced. The one with the better battery charges with any charger.

I know that many users get fixated on official HP specs, although many times specs can be wrong.

Anyways, visiting the HP Store for one of these systems (AMD) does inform one that PD is 3.1, but it also verifies that USB-C charging (although it works) is only a last resort auxiliary method:

[resistencia]

Yes, HP is often unclear about specifications or makes mistakes. If you look at the service manual, it says it has two slots for PCie 4x4 disks, but when you look at other information, you see that this is false. The second slot is 4x2, which is half the speed.

And that note isn't included in the link you're offering us.
