Charge USB C PD Power bank from laptop - General Accessories

Hello,
so I have a POWERADD EnergyCell 10000mAh PD Powerbank.
I can charge it using a USB C/USB C cable from my Galaxy Note 10 25W Charger.
Also I can charge it from my Laptop using USB A to USB C Cable.
But when I connect it to my Lenovo P71 via USB C/USB C, it seems to try to charge the laptop (which will not charge with 18W or the 25W charger of the Note 10).
I actually would need to tell one device, that the power should go from the laptop to the power bank.
Anybody have an idea, or a power bank which is charging that way?
My P71 still has USB A ports, but in the near future I want to charge my USB C Power Bank from my USB C Only laptop.
David.

I hope it's ok to push my thread after months.

[Review/Comparison] Choetech USB Car chargers QC3 USB (T002) & USB C (c0051)

Review/Comparison between Choetech USB Car chargers QC3 USB (Tc002) & USB C (c0051)
(Note this is tested on HTC 10 with a choetech USB C cable)
USB QC 3 charger (Model tc002)
This is a nice little charger, small form and built well. It has a little led in the middle to let you know it has power/is charging. It also comes with usb c cable which is a nice addition.
It has 2 ports, one with a blue strip around it to let you know it’s the “main” QC 3 port. This port gives off 9.1v with 0.83a. The phone recognised this as QC3 and displayed the “charging rapidly” sign.
The 2nd port has no strip around it. It gives off 5v and 1.9a, so will charge slightly slower but still for an in charge charger will charge most phones well.
USB C QC 3 charger (Model c0051)
This is a nice little charger like the above, very similar build wise the only difference being the ports themselves. Please note no cable was provided with this charger. The led also changes from blue to green when charging.
It has 2 ports, 1 usb c and 1 normal USB (USB A). The normal usb port also looks reversible which is a nice added feature. The usb C port requires a USB C to USB C cable.
The normal USB port gives off 8.8v and 1.5a. The phone did recognize this as QC3 and displayed the “charging rapidly” sign.
The usb c port I was unable to read due to not having the right connector to read volts and amps, so I used an inbuilt amp to read the charging speed (Ampere). This read as 1800mA which as comparison is around the same as the official HTC charger that came with my HTC 10. The phone however did not display the “charging rapidly” sign
Conclusions
Both are very good chargers and both available at a reasonable price. If I were to pick one I would pick the 1st USB QC 3 charger (tc002) simply because I feel the double usb a ports give you more options when charging

Will using a USB-C to USB-A cable remove the quick charging?

You need to use quality charger with 3.0A for that
a good/proper usb-c to usb-a cable is supposed to have a built in resistor to keep the device from pulling too much current through the older usb-a plug, which ofc wasn't designed with the capabilities of usb-c in mind.
therefore you should not be able to charge as fast with said cables, otherwise it wouldn't be too unlikely for your device or charger to get seriously damaged.

To be more precise, the resistor doesn't keep the device from pulling too much current, it tells the device it is connected to a legacy cable and it should limit to .5, .9, or 1.5A. The device can still choose to pull more current if it has alternate means of figuring out the capabilities of the power source. It won't be using facilities within the USB C spec, but it will still work fine.
My bedside combo of a 2.4amp charging brick, anker powerline 10ft micro usb cable, and anker micro usb to usb c adapter gives me quick charging. The cable and adapter also allow data transfer and adb from my macbook pro.

In my experience 5x says "Charging rapidly" around 1.6A. Some of the legacy USB A -> USB C cables (either direct or through micro-usb adapter) can get around 1.6A and 5x will display "Charging rapidly" but this might not be the same rate as the stock USB C native charger with which the device can pull 2.6A for the lower battery ranges like 0-40% before the phone slows down to around 1.8A (and even slower later on in the cycle)

Discovered this after returning my 5x, picking up a 6p, and installing ampere. Still functional as a bedside charger but thanks for the help tho.

Quickcharge

I have a Nexus 5X, but I bought it only with USB cable type C to USB type A for the computer. The charge is quite slow with a Samsung charger, I want to know if any QuickCharge charger with USB 2.0 with my cable type C have no problems chaging or it's possible to burn something... In my town nobody sells USB type C fast charger.
The Nexus can pull down 15 Watt of power for a quick charge. Your typical USB 2 port is rated for 2.5 Watts. So, no you cannot quick charge the phone without having a charger that is rated for it. And you should not try. There USB C to A cables not built to USB C specs and they actually try to pull 15 watt no matter what the source can deliver. This is dangerous! Just Google it and read about melt downs and fires...
You should be able to get a USB C charger wherever you bought the phone

On Amazon Look for USB Charging Station that can charge 6 Phones at the same time. It has 2 Quick Charge ports and comes with 1 USB C Cable.

Charging Pixel XL by using Laptop is extremely slow

I have got unlimited mobile internet and actually need to connect my mobile to laptop for USB tethering as have limited internet for WiFi tethering. I previously had used many phones but they were charging at good speed when connected with USB ports on laptops but PIxel XL is very slow.
"Charging slowly" = below 1A (at 5V),
"Charging" means between 1A and 1.5A,
"Charging rapidly" means more than 1.5A
I am using Anker USB C (male) to Micro USB Adapter (female) to connect it with usb ports of Laptop. I have usb 2.0 and 3.0 ports on laptop but it dont make any difference and charging is still slow. Is there any way to make it charge faster or even at medium speed between 1A and 1.5A ?
Thank you

I believe that 2.0 is only able to output 500 mAh and 3.0 is 900 mAh.
All the non-charging ports on my PC are 500mAh for the USB 2.0 ports.
It's how it's been with every phone I ever had.
Industry standard for a non charging USB port AFAIK.
Thanks guys for your response
So it dont matter what USB cable you use and it will still be slow charging? Its second time i am using phones that use type c charging.
My previous Samsung phones had normal usb ports and they were charging fine with laptops and charging was not this slow . Is it type c thing that make it slow when you use adaptor to covert type c into micro USB?

It's a placebo. All phones charge at 500mah on a laptop. The Samsungs probably didn't have such big batteries or had better battery life so you felt you were charging your phone less.
You would be better off carrying a quick charging battery pack.
USB 2.0 runs at 500mA at 5v, giving 2.5W
USB 3.0 runs at 900mA, giving 4.5
To put this in perspective, our oem and Google store sold chargers are 18-22 watts.
Very few pc ports (unless specified) will give you decent charging speed. My ECS motherboard has pin outs for quick charging at around 15watts.
Look for some usb hubs with power delivery.

USB C cable?

Woke up today and tried to charge my phone but turns out Google USB c cable isn't working,now I don't know what happened overnight but it's not working, are there any alternative good USB c cables which can provide rapid charging with Google charger?
I've had nothing but great luck with this cord. Have them I every room and cars.
