Q: Yoga 3 Pro / UNIFUN power bank

Hi everyone, I am trying to find out if the yoga 3 pro has the ability to be charged using a power bank and the original lenovo power cord ( usb adapter). The power bank i am trying to use is a unifun power bank i have also tried the mophie with the dual usb port for smartphone/tablet. The specs for the unifun power bank are Specification:?Model: U821 ?Capacity: 10400mAh ?Input: 5V/2A ?Out1: 5V/1A(MAX) ?Out2: 5V/2 .1A(MAX) Or if there is a power bank out there that does charge the yoga 3 pro what is it?

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.

Regards.

I want to get a power bank that can charge my Yoga 920 via USB-C.  What are the requirements for a power bank to do this?  Power Delivery?  A certain voltage?  something else?  I don't want to order one only to find it won't charge the laptop.  For example, I'm considering the iWALK Secretary II 10000 mah Power Bank.  Thanks!

Just got a Yoga 700-11ISK. It's great. Love it. Want to know how I can charge it from a power bank. The battery life is good-not-great. I know it needs 20v. If I snagged a 24v power bank and used the USB C cable,  would I get a charge? Anyone have alternate suggestions? I'll solder together something totally unsafe if need be.

A:Yoga 700 - How do I charge it from a power bank?

I am getting some info from the Lenovo team on the USB Type C port if it supports audio, video or whatever application however seems to be that the Type C is just another USB port for portable devices such as external HDD.There have been discussions about charging the laptop via Type C however I don't think you can as its only suppose to charge via the AC port. Don't fry the mobo mate.

Greetings from Portugal. I'd just like to say that i've found a powerbank that can be used with the 900s (and probably others that use the same charger). The one i found, and can confirm charges the laptop, is "RAVPower 27000mAH Powerstation" that i found on amazon.It's a powerbank with a regular power plug to connect the charger, so it could be called a mini ups instead of a powerbank. Hope this helps people looking for something similar.

You can find a huge collection by searching ?power banks for laptops? on a search engine. You just need to compare things like capacity, weight, and price.  The power bank should have a USB standard charging port and a DC output port as well.

The less they weigh, the less mAh (power) they contain. In other words, to last longer requires more batteries, and the more batteries the heavier.

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.

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,

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.

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. The PB comes with 8 adaptors; for Lenovo products it lists a  7.9*10 mm adaptor. 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. Can someone with expertise advise me if I'm Ok to go ahead with the purchase based on the features? Many thanks!

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down. Culprits are bad power bric/cord/plug or power socket on mother board or power board that feeds into power button/led on. One day it blacked out and wouldn't restart to hard drive or windows stage. I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge. Left it overnight and then it miraculously charged up. pushed power button light up twice then nothing. took out power board/detached ribbon, then it fired up to windows, fixed some hd errors and has been restarting without problems. Except now there is no plug showing on battery icon when plugged in. So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up. So power socket and plug may be suspect with intermittent contact problems. Or the power board somehow is involved in this? I've ordered a new powerboard as easy screw in and cheap. My question about powerboard is does this control ability of plug to charge battery? power brick with new plug is next order from ebay. but the power socket, which see...

I usually keep my trusty Yoga 3 Pro laptop beside me with the power cord plugged in at night in sleep mode when I close the lid. This morning when I opened the laptop to turn it on, nothing. Did not start/wake, no power LED either white or amber on side. There has been no trauma - water, dropped, etc - it just decided not to wake up this morning and no power LED is especially troublesome. I have tried to hold the power button in for an extended amount of time to see if it would reset itself, but nothing. My first troubleshooting will be to borrow a friend's known-to-be-working Yoga 3 power charger to see if my charger/power cord is defective/died. I doubt that's the problem, but that's the easy first thing to check. Since I bought the laptop from Lenovo in December 2015, I think the warranty is done, but not sure. (Any comments?) If the friend's charger does not power up the laptop, I plan to open up the laptop (first time for this particular laptop although I've opened up previous Thinkpads and other laptops literally hundreds of times) and disconnect the battery, push the power button for 20 seconds or so and see if there's a discharge that may correct the circuitry. I know I have done this successfully with older laptops. However, I know that Lenovo and other manufacturers are hard-wiring components and making it more difficult to work on. So here's my questions: Will a Yoga 3 Pro power on with a functioning power charger connected and the battery disconnected? I... Read more
