PROS
Simple to use. Intelligent chip that adapts output current depending on attached device. Practical to carry around. Nice way to "recycle" old 21700 batteries.
CONS
none so far
Since I have a lot of old 21700 batteries (used for vaping) this is a nice way to extend their life cycle.
With time, used batteries in vaping equipment tend to lose some of it's performance and I opt to replace them. But for this type of equipment, with low current needs, old batteries are more than sufficient and are a very cheap method to gain a nice battery pack for charging mobile devices during the day when outside.
