    Good battery backup for travel. I was able to charge phone and ebook reader off of one charge. It is a little on the heavy side but has a slim profile for fitting into handbag or backpack.

    Fast charging of my phone and it only uses a fraction of the fully charged Anker powerCord III. I'm really happy with this one. I would buy it again.

    So far it’s been good. Usually will last for a day if used often. Although compare to others I’ve had in the past, it’s not that much better. Very light weight to easy to carry

    We have two of these power banks, and they are fantastic. We have used them on all-day excursions, and they helped us keep taking photos, kept our phones charged, etc. Very impressed on how long it takes to run these power banks down while charging our Google Pixel phones (probably wouldn't last as long with a bigger device like a laptop, though).
