Slow charging from power bank

[Caloy_]

It's really slow to charge, the percentage barely rises. The power bank's output is 2.4A while the original power brick's is 2A. I installed the Ampere app and it measured about 0.4A when charging with my power bank. When charging with the original power brick, it measures 0.8A. I tried using the cable included with the phone with the power bank but it still measures 0.4A. I tried the power bank and K4 Note power adapter on my Nexus 7 and both measured about 0.8A. This power bank also worked fine with my old phone, a Nexus 5. I'm on Lollipop.

I am also facing the same issue....Charging with a power bank is really slow for Lenovo K4 note.

Hi,

Sometimes the Usb cable might be the reason for slow charging. So, Which Usb cable are you using. Try with the one that came with phone box.

Thanks!!

I did try the cable that came with the phone. It was similarly slow.

Have you tried charging any other phone with the power bank?

Yes, I used to charge my Nexus 5 with it and I tried it on my Nexus 7 and it was fine. Sorry, but I mention all of this in my original post.

The charger has intercepted radio frequencies that have triggered it to disable. See FCC 15.19(a)(3). Search that regulation and you’ll see that portable chargers MUST be able to receive interferences, such as electromagnetic waves a.k.a. radio/micro/etc waves, that not only stop normal functionality but also cause functionality of unintended use.
