I had been wanting to buy a battery pack for a while now. I did some research, as I always do when buying something. I saw this pack and I just loved it. I know there are some that come with a wall plug and all, but this just seemed like a better buy for me. I travel every now and then for work, and just for fun, and I have a lot of things that need charging. I have my phone of course the Samsung Galaxy S7 Active, my tablet the Samsung Galaxy S2 8.0, my smart watch Samsung Gear S2, my GoPro Hero 4 Silver, and my Bluetooth headphones. Its been great for all those things!!
I will say this, It takes quite a while to charge the pack itself. I haven't timed it but I want to say it is roughly like 12 hours or so, so I only charge it at night, and only when its fully dead. I like that it has a battery level indicator on the side, and yes it does last a good while and I can get multiple charges for my various devices out of it. Another great feature is that is has 3 ports for charging. One is a fast charging or something like that, and the next one is a little less fast, and the other is just a normal USB port. It is a little heavy, but I always have it in my backpack so I don't feel the weight so much.
