Aiya dont bother arguing with him.

Later he throw you energy ballz.

Tumpang thread. I'm planning to buy a lenovo yoga slim 7i carbon laptop, and it has usb-c charging. Is it possible to use a standard 20,000mah powerbank to charge it on-the-go?

60W fall short of the general market standard of 65W.

If you’re bangsawan, can consider getting 100W PD charger too.

Ugreen >>> all

Those bangsawan brands like Anker, Belkin and etc aren’t as proactive in making a variety of high specs PD charger than Chinamen brands like Ugreen/ZMI/Baseues did.

laptop power bank exists for quite some time, even for old laptop
the only troublesome part is
- harder to buy here
- more expensive, good one usually RM200-400
- usually bulky
- different laptop = different charger plug head, but not a big issue if you only have 1 laptop and 1 phone (it comes with usb port)

now USB type c make things even better
like you can charge your macbook using normal phone power bank, it will be VERY slow but it still charge
some use normal power bank to charge it while it sleep, or just to run few more hours of power
and PD power bank becoming more common

Yes, I charge my iPhone and MacBook with the same USB-C charger.

As long the PB have Type C and supports PD then ok.

Fixed

There’s non-GaN but still PD charger out there. Even Apple’s 87W charger also not yet using GaN.

Sharing me's chargers (100W and 65W), powerbank (65W) and USB-IF/E-Mark 100W dual USB-C cable...

Laptop chargers for desktop and on-the-go variants...

Office desktop:
PROLiNK PDC410001 100W 4-Port USB Charger (Power Delivery with PPS; supports Samsung PD PPS 45W):



On-the-go and smaller 65W charger, me opted for Baseus Gan2 Lite (supports Samsung PD PPS 45W). Below is for the Pro version:

[attachmentid=10741961]
p/s : Was studying the UGreen 65W GaN 4-port charger, but unfortunately, it does not support Samsung PD PPS 45W (please verify...)

Laptop powerbank, ZMI PowerPack 20K Pro (also supports Samsung PD PPS 45W and USB Hub for external HDDs or thumb-drives):

[attachmentid=10741966]

USB-IF/E-Mark certified dual USB-C cable = Pepper Jobs - C2CE1M USB 3.1 GEN 2 USB-C to USB-C Cable.

Micro-USB cable = McDodo Auto-Disconnect CA616


Laptop : HP ENVY 13 X360; USB-C port supports the "Alternate Mode" (Display and Power Delivery).

The keyword is USB-PD and 45+W, you can check the specs list and look for those that can output 20V x 2.25A and above.

I bought this recent 12.12 sale for a stealing offer of under RM170, it normally cost more than RM300. 65W PD powerbank isn’t cheap, even if you go for China brands like Baseus, it will still likely set you back for RM180++

Yes powerbank has PD, but why is PD needeed? If without PD will not charge laptop?

Ensure the laptop/device's USB-C port supports charging. No point buying the charger/powerbank if the laptop USB-C is doing data transmission only...

It’s because laptop charging through USB-C depends on the USB-PD protocol.

Without it (on both laptop or charger), you can’t charge the laptop.

Thanks, I'm using this powerbank now. https://shopee.com.my/product/108097613/272...04-1610870003.9
I googled it and the amazon result says got PD support, but im doubtful, hmm.

my dell and my thinkpad are using different charging port...and it's not USB-C

With PD, the laptop will negotiate with the PB for higher voltage/current automatically.

Without it, the laptop may not be able to charge due to insufficient current or wrong voltage.

yes, it's called charging over usb C

PD got many voltage one.

If you’re planning to charge laptop, you’re looking at those that have high voltage output (20V or 15V one). Most laptop’s PD is based on 20V, some others like surface or Apple may based on 15V.

18Watt output can only charge laptop when the laptop is turn-off/standby... We need at least 45Watt to charge laptop when it's on...

Ok thanks, so I better not try my luck to charge it with this powerbank then. Later kebaboom the laptop.
