I’ve owned several external battery packs over the past few years and none have even come close to the quality and/or value of Anker’s packs. I now own three that I carry with me on a daily basis. I’ve taken them to web conferences, on multi-day road trips, to Walt Disney World... And they’ve exceeded my expectations each and every time.
