hi, I have a Swift N20C12 laptop with a thunderbolt 4 connector. does this laptop support charging through this connector?
[Edited the thread to add model name to the title]
Some versions weren't equipped with a thunderbolt port? Does your port have the TBT4 lightning bolt symbol? If it does, it should support power delivery for charging the battery pack.
the lightning bolt symbol is there. I am asking because I would like to charge my laptop there instead of the standard adapter which is large. what parameters should a usb-c (thunderbolt) charger have?
Mainly about the same power output (watts) as the standard adapter. If you have the SFX14-41G, the standard adapter output is up to 90watts. Pretty big. Unfortunately, a thunderbolt charger of similar capacity might not be much smaller. Anker usually has about the best selection/prices.
This is my adapter.
Should I look for an adapter with the parameters 19V, 3.42A and 65W for the usb-c adapter?
You might be OK with a 45watt if you don't expect to constantly run power-hungry games or heavy-duty a/v editing software
Good luck. Let us know what you decide on and how it works out. Thanks.
Without knowing your full model number, something like the SFX14-41G-xxxx suggested above, we can't be sure what voltage the USB-C/TBT charging supports. Many USB-C charge devices don't support all voltages allowed. It's likely to work with 20V but might not with the lower voltages. 19V isn't an option for USB-C charging...
Where can I find the full model number? I have a photo of the laptop from the bottom and a photo of the charger. Here.
Your model number is Sf314-511. TBT4 ports accept any power delivery adapter with 5 to 20 volt dc output. For your model. as mentioned earlier, you can probably get away with a 45 watt adapter to cut down on the size.
Edit that third image to blank out the SNID too... It's better to get a 65W adapter, since that is what spec calls for with your laptop. Too small and it might not keep up under heavy use with the charger connected, gradually discharging the battery when it should be maintaining or charging.
