Since I own a gaming laptop (XMG a505) and travel a lot while traveling, the standard charger is rather impractical, as it is quite large and unwieldy. Are there power supplies that have the transformer directly s.den outlet and still can supply a Gmaing laptop with power? (My current original power supply has 120 watts) And how is that, for example? For cars on USB adapters. If the adapter is rated at 90 watts and the USB port is only 15 watts out, can I use a USB to AC adapter to charge a gaming laptop?
You can also take a car adapter 12V to charging voltage, if you have the appropriate connector (NV-hollow connector)
Do not know me with electricity or tension unfortunately sooo good! What is a NV hollow connector?
Low voltage plug with hole. https://www.amazon.de/...0002W6C2G/
That is the same, with which you connect also your 120W Homenetzteil with the Läppi…
And would it work to use a normal car USB adapter with 24 watts output power (ie those with only USB ports) and connect a USB to AC adapter? (My current betzteil has 120 watts)
Achso
No, you do not get far with 24W. You can't make 120W from 24W.
Ok, then I have to spend a little more money! One more question: Are there power supplies with about 120 watts that have the transformer s.der outlet? (Namely none on Amazon and on the Internet)
No, over USB you do not get enough power over. Normal Usb brings max. 1A. That's just 5W at 5V. Your Läppi laughs about it. You buy a suitable car adapter for your Läppi, just so you bring enough power over…
There's no power supply for the Läppi, there's not enough space for a powerful charging electronics…
The MacBook power supplies have the transformer but s.der outlet, but probably has to do with the fact that the parts have only 65-90 watts?
