Bests & Worsts Reviews from Amazon

Having used this battery pack intensively for about a week, I would say so far I'm impressed. Here is a quick run-down of the pros and cons: Pros: 1. Super quick charge (< 4 hrs to full) but with surprisingly large capacity - enough juice to feed my iPhone 7 4X or roughly one light per charge cycle for my phone. 2. Having used plenty of portable chargers in the past, I've found those real tiny ones are pretty much useless while the bigger ones are often too thick or too long, awkward to carry with the phone. This one has got just the right foot print - it's a shade shorter and thinner than my phone (see picture), so the two stack up nicely and can be carried around together like good companions :) Cons: 3. I would have liked it even more if it were in white or a lighter color, which helps the battery pack stay cool, especially when you forget and leave it in a car under direct sunlight...
