It is very portable and efficient. I use it every night and for my trips It has both the 100 watt charging for USB c and A. I do not need to carry my laptop charging anymore since this is powerful enough to handle my device charging needs. I do not like wires all over my charging area. This simplifies this for me.
The only small drawback is that it heats up a little...this is not an issue..
The fast charging on my Samsung s8 ultra is like adding a spark to jet fuel.
