Momcozy Portable Stroller Fan Review/Unboxing  

With it being a 8000mAh battery, its basically a power brick. So charge time is very dependent on the output of the charge source. For instance, if you’re using one of those little 1 amp bricks that used to come with phones, it would take quite some time. Of course other factors go into it too, but I would make sure you have atleast a couple amps that you’re charging it with. Glad it works well though!
