While smartphones these days are getting better in the battery department, there is still room for quite a bit of improvement as the batteries in our devices could stand to last a little longer than they do on average. That being said, there is a solution of your battery doesn't last as long as you need it to, and that's a battery pack. Generally battery packs can end up costing quite a bit if you pick one up that has a large battery capacity. Right now, though, you can actually grab two different battery packs from Jackery that are on sale for today only. This is the Jackery Thunder 20100mAh battery pack for just $29.99, or the Jackery Thunder 10500mAh battery pack which is on sale for just $22.49.
Both of thesebattery packs support Quick Charge 3.0 so if your phone supports this charging standard, then you'll be able to charge up its battery very quickly which can mean all the difference. Both packs come with dual-USB charging ports so you can charge two devices at once if you need to, and each pack also has a set of LED indicator lights on the front which can help you identify how much battery power that the pack itself has left before it needs to be charged back up for later use. You'll also find that each pack comes with a nice large power button for turning them on.
