This battery pack and wall charger combo is a beast. It has replaced my other chargers that I bring with me when I am traveling.
Gone are the days of waiting 8-10 hours for my battery pack to recharge when this recharges in just 4 hours with the included 30W wall charger. Also, with its USB-C port as well as regular USB port, rest assured that all your electronics can be charged.
The 20,100mAh power is also the perfect amount. It can recharge my MacBook 1 charge, my Nexus tablet 2.5 charges, and my OnePlus 5 cell phone 6 charges. Besides the awesome perfomance of this battery pack, this thing looks good too. It has a nice matte black finish which helps with the deterrent of smudges and fingerprints.
Did I mention that this thing recharges in just 4 hours??? 
So go get yours today!
I will be posting my review soon.
