So this is my first big portable battery, by big I mean both size and having more than one charging port. It was cool that it was mostly precharged out of the box, but a friend recommended to charge it to full capacity to ensure longer life from it and a better ability to hold a charge later down the road.
So there's a few things are knocking this down from a 5 star product to a 4 star. First, price. OK $35 is reasonable, but compared with $5-$10 for smaller ones, it's a lot, even given that it's a much bigger battery. Second goes hand in hand with being a big battery. I love the capacity, but I'd like it to come with a longer charge cord. I get that one doesn't generally need a real long one, but this one that comes with it is literally less than 6 inches long. It's almost useless it's so short. And those who shop around know that a 3-6 ft cord ain't cheap. This is just a way to squeeze more money out of consumers. A plug in power adapter would have been nice, but I can also see why they didn't include one.
As far as performance goes, it is a bit slow to charge things, but amidst the mixed reviews I've read I personally have had absolutely no real issues with this in terms of performance. Would absolutely recommend for someone looking for a big, yet portable battery on a modest budget. Just expect to use your own charge cord or shell out for a new one, cause you can even tell by looking at it in the box that what comes with it ain't nearly long enough. Other than that though, I absolutely love this.
