I have a Samsung Galaxy S4. It has it's own charger with a detachable cable, able to go to USB ports. This one to be exact, it works perfectly. I also have a Surface pro 3 and it's charger. As can be seen from the picture, it has a USB port for charging, it also works. It's when I combine my Surface charger and my Samsung cable, that I get a problem. The lightning icon appears on my phone, but it's not really charging at all. Changing the cable with my other cables fixes it.

  • It might be that Samsung is shipped with a non-standard proprietary cable design in order to make you buy the overpriced original. – jediz May 19 '17 at 7:25

The Power which your Phone consumes outway the Power a USB Port can supply.
This problem is often faced when using an Powerbank.

Cause could be an old Battery which lifetime is coming to a close, but thats anyones guess.
I would buy myself a charger that goes in to the Wall socket. Way more convinient.
For example, it would take 5h for my Nexus 5 to fully recharge from USB and only 2 hours from the wall Socket directly.

  • Why do you think it out-ways the power a USB Port supplies? I've clearly stated that just switching the cable fixes everything. Also this same cable works with the original charger, so it's their combination, not an individual part. – Lubo Kanev May 21 '17 at 15:53
