Excellent especially the advice that makes sure you do not get scammed and end up buying a charger that is not strong enough for your laptop.

That's a nice looking power bank. I love the low profile

[DpakSharmaNoida]

How beautiful the world would be if we won't need to charge any device ever.

[MrShekoto]

Excellent information
Thanks for all the information

My question is how the laptop will handshake with the charger the adapter doesn't have the data cables for the communication, a charge starts with 5v and then pumps more if the device supports it. I think that's the handshake part, it either works with data communication, or ir just uses the resistance response

I wish I had found this video several hours ago when I first started researching this. Unfortunately, I need a 150w (19.5v x 7.7a) power supply and I'm having difficulty finding anything compatible. The connector type is a 5.5x2.5mm for a MSI GE62 2QF. Is that simply too high a wattage for this type of usb charging set-up?

[Nayan-icig]

nobody explained better than you mate👍
1 question though. i have a 33 watt xiaomi charger. will it charge my laptop, if its slow then also i don't have any problem?
my laptop charger rating is 65 watt = 19.5 v, 3.33 a.
thanks

I have a Dell G15 laptop. The current charger is 240w, but I'm thinking about trying to charge it with a 100w power brick and a USB-C to DC adapter. Has anyone tested it to see if it works?

[phoenixhenson]

This is the most educational video that I have seen on YouTube in years👏

My laptop has 19V 3.42A = 65W proprietary charger. Is it safe if I use an adapter or power bank with 20V 5A = 100W? Won't it fry my laptop?

[Hi-qkfj]

if my charger is 20V 3.25A and power bank can only output 15V 3A or 20V 5A, will it still be able to charge?

[mr.k]

Is the literature safe on the laptop?
My laptop works with 65 watts

[Orvis]

Out of curiosity, what happanes if you use a lower end charger?



I assume it won't kill the laptop, there is probobly some protection circuit l, but would it charge (at all, even if only when off) or just slowely discharge; at all like mobile phones, or just decline to charge all together?

I'm currious how windows and the hardware would react to that situation.

[andreydolg]

Thanks for video!) But not sere why you suggest to use max total power of laptop stricly even if your laptop eat 120W(on it max usage CPU + GPU) and you give him chanrger with correct voltage but less Amper(say 19.5v*3.2A(65W total)) it will work but just will required a lot more time for charge. For some laptop wich max power usage is upper then 200W it's only one way to use usb-c it accept less powerfull charger.

[julietonuoha]

Please i need your reply 😟
my laptop normal charger adapter is 19.5v × 2.31A (45 watts)
So i want to buy a 100 watts usb c charger

1) Can i use a powerbank with 20000 mah and 65 watts + the 100 watts usb c pd charger, to charge my laptop ? Will it work

2) What capacity of power bank should i get instead ( must the power bank be up to 100watts)

I use a hp 15 notebook

[electricman]

Do you know why 100w USB-C Adaptor shop says that it also supports 18-20 volts devices?

[betttygsilasie]

Thank you I followed your recommendation and it worked, Thank you very much! I actually saved myself from buying a new laptop with USB type C. But for the power bank, I purchased Anker 65 W and the adapter similar to what you showed in the video cause the item was sold out already. But everything worked perfectly. Thanks a bunch really!
😁

[karlhui]

Follow up question: if you use a USB -C charger with a higher voltage and amperage than the original power brick will it blow out the laptop?

[LeonPajuelo]

I'm pretty sure that I run out of luck because, the original charger of my laptop (Asus K55N) is 19v 3.42A, and I couldn't find any PD or GaN USB charger.
😢

[betttygsilasie]

Thanks for the video it was a lot of help, i have a que though, can a 65W charger charge 65W power bank or does the charger need to be a bit higher wattage?
