The Luxa2 EnerG Silm 10,000mAh Power Bank is a great gadget with a solid construction and build. These power banks are often hard to review in such a short amount of time. While working on other reviews, I was able to travel with it and use it daily to grasp the feel of everyday use. While this is more of an extreme for some, it's hard to predict what the average user will use it for. I am on my phone half the day and found times where I was away from a power outlet for 12 hours while at my day job. That being said, Luxa2 does a great job of providing devices that fills the gap between unwanted downtime. I was able to charge my phone and other devices in just the same amount of time from a outlet, and while it was in my pocket! Combine that with a half life of 1,000 cycles, this power bank will outlive it's warranty as it's simply not possible to get that many charges out of it, even if used everyday. Many brands I've come across provided very limited warranties, leaving you to wonder if it will hold a charge the next day.
