I was gonna buy some 14k but you have to consider what you actually need and if you're okay with all that weight/bulk
unless the primary reason is for traveling/vacation or you need it to charge a laptop...you probably dont need more than 6k
the flashlight isn't an afterthought...whole thing is well put together. I'd rate ravpower up there with anker
3000mah will give you a full phone charge and enough for a tablet for an extended day
