P50 - charging from portable power bank

Q: P50 - charging from portable power bank

Hi,just wondering if it is possible to charge my P 50 using a portable power pack whilst camping etc?Ideally, one that doesn't require my 170w, slim tip charger; but a solution of any sort would be great. I had in mind a powerpack which could service my laptop, as well as phones, USB devices and so on; but all my searching has led to dead ends.Electrics aren't my forte, so any advice appreciated, Cheers angus.

Has anyone tried this or have a story to tell about power banks?My relatively new X1C does quite poorly on battery if I'm doing real work, e.g. compiling and running apps with Visual Studio & SQL Server.  Fiddling with the battery settings doesn't make that much of a difference so I thought why not carry a brick with me when on the road? I'm just starting to look into it but real stories from real users are just so much better than generic 'reviews' or hidden adverts that have become all too commonplace in the last few years.

Hello,

This problem is from a friend of mine but he doesn't has a computer now. Yesterday he was charging his powerbank through his Laptop (Asus bought 3 months ago) USB port. After a while the computer was shutdown and won't turn on, even when it's plugged through its power adapter.

Is there any solution to this?
Thanks!
 

A:Laptop wont turn on after charging power bank

Hi and welcome to TSG.

As annoying as it can be to have to do it, your best option if it appears totally dead is to RMA the laptop if it is only 3 months old. Fiddling about with it too much trying to diagnose the problem could end up invalidating any warranty your friend has.

The only simple checks I would do are to try and power it up with and without the power cord connected.
Then remove the battery (assuming it is a removable one) and try it again with the power adapter attached.

It could be a problem with the laptop or that the power brick has just failed, it happens occasionally.

I just purchased a RavPower 26800PD from Amazon: https://www.ravpower.com/26800mah-Type-C-external-battery-charger-black.html It shows as having 30W of Type-C power for charging USB-C laptops. I have connected it to my Laptop but don't see any indication of charging.  I do hear a tone but see nothing in my battery icon or notifications windows. what I have tried:Fully charged batteryPressed the restart button on batteryDifferent USB-C to USB-C cableConnected laptop with a USB-A to USB-C cableLooked for updates to the laptop (only BIOS is new)The Lenovo USB-C charger works fine.  A key purchase reason for this laptop was to be able to charge over USB-C.

I have no experience with that charging bank, but it appears to be underpowered.  You need 20V 2.25-amps (45W).  The maximum output at 20V is 1.5 amps (30W).

Hi,I am going to use my X2 10 (10-n155sa) to travel to Africa, and while there I will be unable to have access to electricity for several days at a time to be able to charge the laptop. I need a compatable battery Usb battery pack that will allow charging of the X2 10 while on the move. I understand Hp have locked out charging from normal third party usb c battery banks with drm? (the few off the shelf third party usb c battery banks I have tried do not work, including converting usb 2 to usb c), so I am asking them what solution they have available to the problem they have created? Do they have their own Hp branded usb battery powered solution available for purchase? It is imperative that this laptop is charged while a dedicated a/c source is not available as the laptop will be crucial to site functions within the field.  A laptop with a flat battery and no way to charge it is a useless paperweight. I am sure I am not the only one in a similarly presented situation, with no current way to charge from a usb power bank, even if just for generic traveling without access to ac for several days. Or does anyone know of a known third party combination that allows charging of a 10-n155sa via an external usb c battery bank. It does not matter if it takes several hours to charge and only charges when it is off, as long as there is a workable solution. Thank you for any responses to this problem...

Hi Guys, I have had to change my battery, got a brand new DELL battery but I can't get it to charge...I'm running Windows 10 PRO. I have tried the fixes listed above but unfortunately NONE has solved my problem. Any suggestions?

A:XPS 12 9Q23 Power Charging Disabled / Plugged in, NOT CHARGING

Hi DAEMONROD.
Where have you purchased the battery from? Does the old battery charge fine when plugged in?
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible? 
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. Check the battery health in BIOS (if applicable).
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Test another power adapter and check. If the adapter fits in loose, then the dc port needs to be replaced. You would need this part.
Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.
Let us know if you have any other queries.

Good day and welcome to the community.
 
The Yoga 3 Pro looks for 20V input, 4x what that power bank can output. Also, the proprietary cable has extra contacts.
 
There may be power banks that can supply the proper voltage, but I think it unlikely that one has the proprietary receptacle configuration to match the cable.

Hi all, got this power bank (40AL140CWW) for my P1. It is listed as acceptable for the system on the Option Compatibility Matrix (January, 2019). Got it a while back, tested it, worked fine: https://www.reddit.com/r/thinkpad/comments/9uyew4/fieldtesting_the_lenovo_usbc_14000mah_power_bank/ Using it today (charged yesterday) ... all four lights on the bank come on when I plug it into my P1, but, the system is behaving differently ... previously, the bank powered the unit and its LEDs went off one by one as the charge decreased; the main battery indicator on the bottom did not move off 95%. This time, the main battery indicator shows a decreasing level of charge, and so far, the bank still has four LEDs illuminated. Even weirder, the "remaining time" at one point seemed to indicate the battery was present (showing 8+ hours remaining) but now, even that has changed, and the system is acting like there is no power bank installed at all (shows 3 hours and 33 min [77%] remaining.) I am using the USB-C power cord that came with the bank. Is it defective? TIA, -kj-

Hello Everyone, I am considering the purchase of a specific power bank for my L540 laptop. The product is the Vinsic 30000mah. I can't seem to get clarification on whether my Lenovo laptop will successfully hook up with the PB and take the charge. As far as I can tell, the PB has a lot of muscle and is well-recommended.

It says it has 3 output ports: 1 DC output up to 19V 3.5A, with a max output current of 4.5A; and 2 Smart USB outputs, with output up to 5V 2.4A.  It also says it has 2 Input ports: 1 DC input and 1 Micro USB input. I am uncertain if the specs on my L540 make it compatible with the features listed shown above.
