USB-C PowerDelivery PowerBank (X1 Yoga 2nd Gen)

Why is it not possible to charge the notebook battery with 30W @ 20V?

Why only 45 W and 65 W @ 20 V?

 

I wanted to use this PowerBank with PD support "Anker PowerCore+ 26800mAh Powerbank with Power Delivery"  but only 30W @20V Output. So at the moment it doesn't work if the notebook is on. On standby it works and charges the battery with 30W. Why only when the notebook is off or in standby??

Is it possible to fix this problem with a firmware update? Will an update exist in future?

Hi AndyW1, and welcome to the Lenovo User Community!

 

Everything you've described is consistent with the published specifications of the machine - requiring a minimum 45W @20V to operate, I suggest finding a power adapter which meets the specifications.

I don't work for Lenovo. I'm a crazy volunteer!

Anyone got any suggestions for a reputable powerbank yet for the X1C5/Y2 yet? This is the only one I've found: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Yoga-2017-power-bank/td-p/3730846

Yeah, but if the system is off or in standby it loads the battery. So that doesn't make sense in my opinion!

 

@veriton: thanks, but I saw that topic, too. But the suggested power banks also doesn't support 45W or neither support the power delivery protocol.

@AndyW1: the https://files.xiaomi-mi.com/files/zmi_10_powerbank/Zmi10%20EN.pdf one at the end of the thread might charge an X1C - at least an Amazon review suggested it worked. I'm hoping to see a little more choice/evidence first.

Re: USB-C PowerDelivery PowerBank (X1 Yoga 2nd Gen)

Hi,

 

New on the market, Xtorm XB203 gives 26.800mAh USB-C with 20V-45W. Will this work?

 

Spoken to Lenovo support, they won't recommend this or any other powerbank because if accidently put into the other port, USB-C port (DisplayPort), power is distibuted differently on motherboard with consequences. I'am not sure about this, why would Lenovo design an external adapter with USB-C connector which could also put in the other port?

 

Greetings

Robert

Well, with this one it should theoretically be possible to power the notebook. But it's really big and also to expensive for my purpose. But thanks! 

 

In my notebook I have 2 USB-C ports and both have the same capabilities and could also be powered, so there is no distinction between them.

I've been looking at:

https://www.gearbest.com/power-banks/pp_662137.html

which is called 20000mWh (=20Wh) but if you look at he comments it says it's really 12Wh, but at least one person mentions using it to charge an X1C (i.e. X1C5) successfully.

 

Note: the X1C's internal battery is 57Wh which gives you an idea of the powerbank's capacity.

 

I also found a Xiaomi 20000mWh on the same site on my phone, but can't find it again (edit: ignore that- it was the Xiaomi Power Bank 2C which only has USB-A output)

I've just ordered a  ZMI Power Bank Unit - BLACK 217438201 (https://www.gearbest.com/power-banks/pp_662137.html?wid=21). Note that the GearBest website quotes prices in local currency but it looks like it bills in USD (currently $63.58) so that may influence the card you wish to pay with. It could take 20-40 days to arrive from China, but I'll post back here once I've received and tried it.
