TAMO Portable USB 2200mAh Battery Stick

Says charges 2.1A in description, but in specs, output listed as 1A.

Which is it?

This does not hold a charge for long nor am I convinced it’s a full 2200mAh. My Galaxy s6 has a terrible battery. I walk about 1.3 miles from home to work. During my walk, streaming music and letting pokemon go (I know…) run mostly in the background, I get to work with about 60% battery life left. Within 10-15% more, the phone would just shut off, needing charging.
The same walk with this connected lets me get there with it fully charged still, but by the end of the day I plug in to walk home, starting with the phone at 100%, and the phone could sometimes be down to 80%… while on the battery.
Getting this was a relatively cheap stop gap for getting my new phone and sending the GS6 somewhere to replace the battery, but I am pretty disappointed.
The flashlight is handy for walking home in the dark of winter, though I’ve not used it yet. This might just become a chargeable flashlight that just happens to charge devices in an emergency.
