Are 5 watts really going to damage my laptop?

[eera5607]

Hi everyone!

I have an Asus laptop that can be charged via USB-C PD. The manual says that:

and says this:

I also have a power bank that I would like to use to charge the laptop just 1 or 2 times a month. Maybe less. This is the output information of said power bank:

 

So, it can deliver 60 watts (20V 3A) and the power rating listed for the laptop is 65 watts (20V 3.25A). My question is: is that difference of 5 watts significant enough to really damage the battery? 

 

Thank you!!

Well I'm not sure about 5 watts but one thing I could see is if the wattage is higher than what is rated, it can over time damage the charging system. If you ever watch a Louis Rossmann YT video on him repairing MacBooks because they cannot charge anymore, its because the customer is not using the charger that came with machine.

being under in amperage is fine, if you wanna be super safe just avoid doing any heavy load while using the power bank (even tho its probs fine).

Thank you. In this case it would be 5 watts less than rated by Asus. Is less wattage going to damage the battery? The voltage is the same. The difference is the amperage (3A vs 3.25A).

Oh oops, read the question and thought it was based off that compared to 3.25A. 0.25A lower should be ok I believe.

Thank you. Yes, that is what I tough. My main concern is that is going to overheat the battery as sometimes happens if you use a slower charger on a phone.

I would highly advise you don't use knock off chargers. They're usually very shit and can indeed cause damage. Same for cheap battery banks, they are designed for replaceable phones, not expensive laptops. Proceed at your own risk

Thanks. Would you trust this one? https://www.amazon.com/Portable-RAVPower-20000mAh-High-Capacity-Compatible/dp/B082PGS78L/ref=sr_1_3?dchild=1&keywords=RAVPower+PD+Pioneer+20000mAh+60W+2-Port+Power+Bank&qid=1593654021&refresh=2&sr=8-3 

 

I have use for a few months and seems to be fine and of decent quality. It has 4.8 stars on Amazon, and it is advertised as a power bank even for laptops.

I wouldnt trust it with anything other than my 100$ phone, let alone an expensive laptop
