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.
This video is amazing, bravo.
thanks for this, might try this!
That's a nice looking power bank. I love the low profile
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!
😁
Thanks for this video!
Great tutorial very helpful!
Glad it was helpful!
Great. You are so helpful ;)
Glad to hear that!
Exactly what I was looking for! Thx
I'm glad it was helpful. 😄
nice. i will copy this
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
There is no direct communication between the charger and the laptop. The PD to DC cable I recommend contains a circuit that senses the required voltage and handles the handshake and communication with the charger to ensure the correct voltage is delivered.
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.
I'm sorry, if I made you misunderstand. I'd recommend using the info from the original laptop charger as a starting point to figure out the minimum power needed.
It's totally fine to use a USB-C charger that can deliver more power than required.
By the way, back when I made the video, even 100W chargers were big and pricey. So, I'd like to have something small and easy to carry around.
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?
Indeed, currently most charger can output at 20V 5A which might work for slower charging. But using it when the battery is low or during high CPU usage might be challenge.
Moreover all the DC to PD adaptor in the market now only accept at 100W max.
@@simplymaker Oh well. I am planning a sustained bikepacking trip (several months to multiple years) and I didn't want to have to lug 3.5kg worth of computer equipment with me, nor do I want to buy a new laptop. I don't mind a slow charging speed, and I guess I'd have to avoid gaming on it with a 100w power supply, but I was reading that having too low a wattage supply can cause problems for a laptop and possibly damage it.
Worst case scenario, my legs just get an extra work-out.
I tried it on a deskmini x300 which comes with a built in 120w adapter. The power bank I use is 100w and only reaches the BIOS
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?
I'm glad you found the video helpful! To answer your question, a 65W charger should be fine for a 65W power bank.
The main benefit of a higher watt PD charger is that it can deliver higher voltage to supported devices. In the case of a laptop, if the charger can't provide the required voltage, it won't work. For devices that need a specific charger, the recommended minimum wattage is usually specified in the manual.
However, for general devices using a native PD port, it can adjust the voltage based on the input. The worst-case scenario is it will charge slower, but it will still work.
A higher watt charger is also beneficial when using a multi-port charger to charge multiple devices at the same time. Just be careful when select the charger, as I mentioned in the video, the wattage advertised on multi-port chargers is usually the combined maximum wattage, not the single port output.
my acer nitro 5 dc input rated as 19.5 volt in 9.23A = 179 Watts, so are there any type c power adapter that can substitute it?
Sorry, but as of now, the maximum output on a single port PD charger that I come across is 100W.
Out of curiosity, what happanes if you use a lower end charger?
My laptop is 65w (@20v), but what happens if I use a usb charger that is lower voltage or wattage?
For example, what if i use a charger thats only 45w@20v, a 20w@10v, or in an emercency, i use like a standard 5v2a(10w) 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.
I think it's no risk on your laptop, it just not charge or charge slowly. But on chrager side it may overload your charger.
Did you find out?
Do you know why 100w USB-C Adaptor shop says that it also supports 18-20 volts devices?
I think they were referring to the PD version. Since PD 2.0, it supports output up to 20V 5A.
I have a solar panel with a DC port that can put out up to 18v at 2.3ampere. will this work for charging my powerbank
The solar panel output will vary depending on weather conditions, so it might not charge without sufficient sunlight. Additionally, you'll need a voltage regulator to convert the solar output to match your power bank's charging specifications.
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.
😢
You can give this one a try:
s.click.aliexpress.com/e/_DEprJ8t
It's a bit bulky and designed for desktop use.
Please note that, I haven't tested it yet, so I'm not sure if it works when you use multiple ports simultaneously. Currently, it's hard to find a decent 100W compact travel charger.
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?
20v 5a should work.
any suggestion for my laptop acer aspire 7......19.5v=6.92A 135 watts
Sorry, I haven't come across a 135W PD charger yet.
My laptop has a 45w battery and it really sucks video editing on it. Its unusable. It has a 150w charger and works fine when plugged in. If I connect a 65w powerbank with this, do you think I will get better video editing performance?
I think most laptop draws power from its battery even when plugged in. Regarding performance, have you checked the OS power management settings? They might prioritize maximum performance when charging but limit it on battery power.
If your power bank can charge your laptop, it should perform similarly to being plugged into an outlet, though high-performance laptops might drain the battery faster.
@@simplymaker Everything is set to max performance even in control panel.
Update: I can confirm that my performance improved with a powerbank but Its only 2200mah so it drained after an hour of video editing but it leaves me with a fully charged laptop once it dies
Is there a way to reduce the charging speed to increase my power bank battery life?
I Have a gaming laptop whose Watts is 240, i need to use it in college for simple tasks not gaming. Can i use this method to charge or it will cause issues?
Yes, if you have a charger that matched your laptop power requirement.
Some gaming laptops have USP-C PD input ports already for this.
can i use 45 watt charger with to charge my laptop that charger with 170 watt ???
thats too low
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?
No, it will not.
If you remove the laptop battery, would the powerbank power the laptop?
The power bank works like a power adaptor. If your laptop can work without battery when plug in power adaptor the power bank should work as well.
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
Having the same problem here...
What happen if i use 45w (20v..2.2amp) instead of 65w (20v.3.25amp)
All be good, just slower charging or even discharging in super hard tasks
@@alexandrshevchenko2061 thnks bro
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?
It's ok if it is PD adaptor. However, for a regular AC to DC power supply, I recommend using the one that came with your laptop.
Using a power bank or adapter with a higher wattage (20V 5A = 100W) is generally safe for your laptop, as long as the voltage is within an acceptable range (19V vs. 20V). Your laptop will only draw the amount of power it needs (19V 3.42A = 65W) from the power source.
it's also important to ensure that the connector and polarity are compatible. If in doubt, check your laptop's user manual or consult the manufacturer for confirmation.
How beautiful the world would be if we won't need to charge any device ever.
What happens if you pick a wrong charger by mistake? If the risk is high I won't recommend doing this.
If you accidentally use the wrong charger, it could damage your device, especially if it's an AC to DC charger with a higher voltage. But with a PD charger, the risk is lower because it adjusts the voltage to fit your device (the voltage steps depend on the PD version, as I mention in the video).
The worst that can happen is it won't charge. Still, it's best to stick with the recommended charger for your device to be safe.
OK
I didnt understand the purpose.
I thought You are replacing Power inpit port in uour laptop with a USB C .
Bit where is the video for removing and Soldering,
One good purpose is you can use small portable powerbanks for your non usb pd laptop
this was a big waste of time

I prefer the AI voice.
Nice video but i have a question , my laptop’s original adapter is work 19.5Volt , but type-c chargers usually 20Volt , if i use this 20V charger do i have a problem?
It will work, if you use usb-c charger with adequate wattage.
@@simplymaker Will a half volt high damage the laptop?
In normal case, it should handle extra 0.5 volt but I cannot garantee that. To make sure, use multimeter to measure your fully charged laptop battery. I think it will be around 21v.
@@TvGicik have you bought a 45W adapter?

Both power bank and charger should work. Just make sure that single usb output is more than 45w.
