230W AC Adapater alternatives/travel adapter

Hey guys I just got a Sager NP8153S which came with a 230W AC adapter (19.5V and 11.8A) and it's massive.

Are there any alternatives that are smaller? Or can I use a lower wattage adapter when I'm not gaming and if so how low can I go?

Thanks.

 

I am also looking for a lighter power adapter for travel. wlvtrojan, do you mind to share the picture of the powerbrick specifically what are the dimensions of the male connector?

Currently, I am thinking of combining an HP business 230W Smart Slim AC adapter (7.4 mm smart barrel) ( https://www.amazon.com/HP-Business-Adapter-H1D36AA-ABA/dp/B007QWI2AA) with an adapter that will bring to the 2.5 mm male connector ( https://www.amazon.com/BiXPower-X75-Dongle-Connector-Converter/dp/B00NUG5RWC). This is assuming that the power adapter for NP8153 male connector is the same size with Sager NP8652 (Clevo P650SG)

Per HP AC Adapter manual, the DC output rating is 19.50V (+/- 5.0%) with amperage output as high as 18A. Based on the voltage and amperage you posted, this combination should be sufficent.

 

Yeah I was looking at that HP one but it doesn't seem much smaller than the OEM delta that Sager provides. Are you able to find the dimensions of the HP? The ones listed on Amazon can't be right, because it's larger than the Sager one.

 

Here are the dimensions from the HP manual:
7.9 x 3.9 x 1.02 inches
(200.0 x 100 x 26 mm)

The product no is H1D36AA.

Weight: 1.79 lb (811.9 g)

BTW, you may want to read up this old thread

My original idea of using an adapter will not work based on the information on post no 184 (the adapter can only take up 6 amp continuous current).

 

The 18A it the trigger-shutdown current, not the continuous current as listed on the adapter itself (that would be 230W/19.5V ≈ 11.8A).

Still too much for that 6A adapter, but you'd hardly want to resort to such a solution anyway, except when intending to use a single adapter for different laptops. Preferable is to splice the old plug with the new cable. This is no different from common household electricity wires; cut cables, twine together and drop of solder between each rejoined wire. Then some heat shrink tubes for the voltage and ground and another, larger one to wrap around the cable housing. So ... with this method the HP would do fine.

There's also the Dell PA-9E 240W at 200x95x25mm, which can be either a Delta or Flextronics model.

Btw, can either of you list the specific model of the Sager adapter? And its measurements? Gathered a small list of small-ish, high-power adapters and don't have this one yet.

Yes, you can use lower rated adapters, within reason. Provided you force the dGPU to disabled (browsers can activate it) then -100W is doable, so a puny 130W or even 120W would do. A more accurate check is to measure from the socket with the dgpu disabled and running a cpu stress test. Take the peak, non-spike value and divide that by 1.1 or 1.2 to get at the 'real' value (10-20% is wasted during the conversion socket -> laptop).

In this range there's the 150W Razer model (150x60x22) or the Kensington 120-Watt Ultraportable (142x79x20). The Razer doesn't appear to be capable enough to reach its rated ceiling, but with 130W draw that shouldn't be a problem.

ps.
Make sure to mind the polarity when splicing, especially if the voltage and ground wires have the same colour. A simple check is measuring with multimeter on the old adapter when it's plugged in socket (but not in laptop), and do the same for the hybridized adapter after finishing the mod.

 

Thanks for the reply, I'm out of town right now and don't have the laptop with my, so I'll get you the model number in a couple days
