Battery Bank for S9

[Y0SH1]

Hello,

I was looking on amazon for battery packs for my S9 and samsung tablet. I was just curious whats a good battery pack that goes with the S9? I know some has qualcomm quick charge 3.0? Can i use that and wont damage the battery life on the s9? I know that the s9 is qualcomm quick charge 2.0 but i cant seem to find any on amazon. Also what would happen if i used a 3amp charger? What would happen if i used a charger that wasnt qualcomm quick charge and just a normal charger? Sorry for all the questions im not up dated on this technology. Im just worried about the battery cuz i used the wrong batterh bank and it damaged my s6 edge.

Thanks!

QC3 should be backward compatible with QC2.

A 3A charger will just charge it more slowly.

Backward compatible? So that means it still will be good to use the qc 3.0 with the s9? @Hadron

If the S9 is fully compatible with QC 2.0 then yes, a QC 3.0 compatible charger should work with it as well.
