Fast charging with a great design
Two USB ports
Charging via microUSB and USB-C
Not a design for all
With 10,400mAh on Inside, two USB outlets and fast charging technology, the Pebble P1 Pro can be one of the best versatile power banks you can buy at this time. This has nothing to do with the deceased watch brand, but it is called Pebble because of its curved edge design.
This should be able to recharge most phones at least two and a half times with a single charge, plus this power bank can be charged by either microUSB or USB-C, so you will not need to have a specific cable with you to pump it again when it has run out.
Poweradd Pilot 2GS 10,000mAh
Still quite heavy
Poweradd also offers a great slim portable charger, and is one of the cheapest options on this list, but it does count with a substantial 10,000mAh cell inside.
