TabPro S charging slowly

[john7520]

Hello,

I purchased an older samsung tabpro S  (windows 10):

https://www.samsung.com/nl/tablets/others/galaxy-tabpro-s-12-inch-black-128gb-wi-fi-sm-w700nzkaphn/

Everything seems to work fine, except for 

charging. The battery quality is 95% according to various apps. Still, when I work

plugged in, the tablet discharges faster than it charges up. I tried various 

chargers and cables. Some seem to work better than others. So I got this

genuine one from samsung, after some research:

https://www.samsung.com/nl/support/model/EP-TA800XBEGWW/

But even with that 25W one, the battery level still drops slowly, when 

working on the tablet plugged in.

According to several battery usage apps, it charges at a maximum of 9W

(batteryinfoview), and used probably more, because the level still drops slowly.

Is this the correct charger to use? Any suggestions are welcome

thnx

Hello

I found the right charger. After contacting samsung customer care, I purchased an EP-TA800 charger. They said that would probably work. And it did, but according to

batteryinfoview, I still only got a 9000 milliwatt

charging rate, where the charger is 25W. Finding the actual specs of various chargers (volts/amps)

is quite difficult, eg there is no info on samsung's website that I could find.

So I googled numerous images 

depicting the backsides of the chargers with technical specs. I found that the original

charger shipped with the tabpro is EP-TA300, and that one has a max output voltage of 12V,

1V higher than the EP-TA800. So I purchased that one aswell and yes: now I'm getting double

the charging rate, 18000milliwatts, though it varies a bit. ...

Just leaving this here for anyone's future reference ....
