Good tip, didn't think of that. But if I accidentally plug in laptop to 18W powerbank while it's on, will damage laptop or just won't charge?

Official specs did state PPS, though I don’t have my USB tester with me, so I can’t check what’s the actual result.

A PD 100W charger can charge any PD-compatible device right? The device and charger "communicate" between themselves to draw the correct voltage and current so as not to fry the electronics.

Won’t damage. USB PD is designed to be smart and able to detect if the charger/power supply is fit to charge it.

Thanks for clarifying, no worries then.

no. you need at least powerbank with usb-c PD aka usb-c out.

that's assuming those samseng are not using proprietary shit that are famous with samseng.

also need > 18W. 45W is ok, 65W is perfect.


I started using laptops that are powerbank-chargeable since asus t100ta time. that time using micro usb as the port style, so while slow, can chage via powerbank, or at least make it discharge slower (at the expense of battery life).

protip: install batterybar.




it's free. also whenever you're buying a laptop, bring a thumbdrive with batterbar installer. install this first before receiving the laptop just so you know the laptop's battery is still 100%.

sadly no adaptor that fits my thinkpad

but since each of them comes with their own charges...didn't bother to go waste money on something that can do both

Won't damage coz no power is running thru the USB-C port at all... 18Watt is not enuff for the laptop to even power the Ryzen/Intel/Apple M1 chip....

Careful on the cable too... dual USB-C cable need to have the "e-Marker" chip for smart power distribution....

HWinfo64 is my to go tool to check for battery’s wear and tear, on top of a good check for RAM’s dual channel/latency and the monitor’s panel model.

Me saw on YT that it can go till 50 degrees Celsius... So, did ur unit gets extremely "hot" after 30 minutes usage...?

So long as your laptop is modern enough and utilising close to 19-20V input, there’s USB-C PD adapter for it.

Since such product is invented by Chinese market, the proper keyword for it is “PD诱骗” (literal translation to PD baiting?). There’s tons of selection for it on taobao, sure there will be one that fit.

If your thinkpad is using the Lenovo square port, then Lenovo even have an official USB-C PD adapter for that. No worry of bad workmanship or sub-standard cable.

Janji pakai cables reputable manufacturers?

Nothing too uncomfortable when using with my 45W laptop or 45W PD powerbanms.

Though I’m not using more than 2 ports at once, so your mileage might differ.

i know there is
but the only device i got for using USB C is only my phone and the adaptor is only 15W
so no point buying those adaptor for my different laptops yet

plus right now i got a bigger problem...my dell laptop's battery already bloated and cannot find a replacement
search the serial number in dell website returns nothing
search the model number on google return few models of battery that i don't know which fits, even my computer go to guy also

Tak perlu... janji ada certified USB-IF and e-Marker chip...



Ada banyak yg OEM bawah RM25 dari PRC....

Reputable or not, there’s 2 standards at play here.

One is unspecified USB C-C cable, they’re generally rated for 3A of current, thus under the 20V PD, the maximum theoretical power it can go for is 60W.

Another standard is c-c cable with e-marker chip. Those cable is rated for 5A, and as a result can go for the maximum of 100W PD.

Since most laptops (with discrete GPU) are 65W and above. So if you’re planning to charge laptop, better using 65W charger and those e-marker rated cable. But one thing though, those e-marker rated cable may have compatibility issue with some devices, especially when using with non-standard adapter like the PD to power input adapter mentioned before. I tried once with Samsung Note9, also not working too well.

P/S: oh, and to make it even more complicated. There’s other factor such as USB2.0 vs 3.2 or thunderbolt3 standards for cables I mentioned above.

So you must know in first spot if you want data cables or charging cable.

Haha.... so much for "USB-C" is the standard. Nothing standard about it after hearing from you guys.

So to conclude, say I have a PD charger and USB-C cable from a very recent Apple laptop, can safely use the same combination to charge a Pixel 5 phone?

No offense, but, which dinosaur Dell is this... Me have the Inspiron 7447 (year 2015) and still can get replacement via Lazada/Shopee...
