Bests & Worsts Reviews from Amazon

I purchased this battery pack for a 48 day Cross-US bicycle tour (from Seattle to Boston), where I knew I'd be without electricity for days at a time. This portable charger exceeded my expectations and outperformed any device that companion cyclists were using on their journeys. I used the battery pack to charge my Apple iPad and iPhone 6s - the iPhone which needed to be charged almost every night. The battery pack charged these devices at a fairly decent speed. The battery pack took quite a few hours however, to reach full charing capacity (so I'd just leave it plugged in over night when I had the chance). That said, I really didn't have to charge the battery pack very often, which became sort of a running joke between myself and the other cyclists I was riding with - we just couldn't believe how long this device lasted... sometimes weeks at a time)! Couldn't have been happier with the portable charger and look forward to using it in the future.
