Smallest/lightest available charger for the P52?

2019-08-20, 16:40 PM

I seem to be finding conflicting information online.

 

What is the smallest/lightest available charger for the P52?

 

Would this one work? https://www.amazon.co.uk/Lenovo-Thinkpad-135-Adapter-slim/dp/B00GGBHUEQ/ref=sr_1_1?keywords=135w+slim+charger+thinkpad&qid=1566319178&s=gateway&sr=8-1

 

Or if not, could you reccomend one?

 

Thanks!

I doubt such thing exists. 

The genuine adaptor for P52 is 170W and it has reason. 

For full option of P52 as example, CPU (8850H)'s maximum power might be over 55W~60W, and P3200's power might be near 90W at maximum. A 135W adaptor definitely can't handle that situation.

Thanks for all your help!

 

Also, you should know that I've now since been reading about the P53, and have become obsessed with it. Reviews are far and few between but it looks like a beautiful beast. I think I might try and save a little more and get it.

Helson,  that may be true,  but do the cpu and gpu draw 150 watts most of the time?  Probably not,  and how often would obviously depend on how you were using it.  Also the P52 is well known for throttling when it gets hot,  which can be quickly due to it's weak heat management.  And since you have a battery to take up any power supply deficiency,  I have wondered if a 135 watt unit might work for quite a while for normal use.  For example,  if you get 5 hours with battery only,  then you might get 30 or 40 hours with a 135 watt supply and a battery.  Is this true or am I missing something?
