Definitely doesn't apply enough charge.

Holds a good charge but I felt I had to recharge them a lot

Doesn't provide enough charge

I like hiking, sometimes I hike from morning to afternoon/night, and of course I like to take picture/video anytime when I see something good, the battery easy to run out when on hike, so this portable charge help me a lot.

We left them charging overnight and when we got to our venue and plugged them in, they didn't work.

I plugged another cord in and it doesn't charge my phone as well as with the cord it came with.
