There was a problem filtering reviews right now. Please try again later.
Would love to get it replaced but now SOL.
That aside however, the overall performance of the pack when it worked, was great. Good design, plenty of connection options and quick charging of devices. Most likely got one out of a bad batch, to anyone buying it, I’m sure you’ll be pleased as the second one I have is 2 years old and still works great. Can’t discern much of a noticeable difference in capacity (but then again, the charge this model holds is large to begin with.)
This has an awesome charge retention.
It works fine as a giant battery. The display is always on which shows the percentage of charge you have left. I wish that would turn off to save some juice.
I'm giving this 1 star since all I cared about was pass-through power and that was false advertising.

La única pega, que el tiempo para cargarla es muy elevado, eso que la estoy cargando con un cargador potente de 120 W.
