All battery packs serve the same basic purpose, so each product has to find a way to stand out from the crowd.

Inside the very small package that is the Innori battery pack, is a pretty big 12000 mAh rechargeable battery. While there's nothing too flashy about this pack, the first thing I noticed is the fact that it is just about the same size as any of today's flagship phones — it even kind of looks like one.

Innori USB PortsInnori USB Port Amps

As you can see from the pictures above, there are three USB ports for you to plug into. Two of these have an output of 1 Amp, which is meant to charge smaller items like your smartphone or Bluetooth headphones. The third port has a greater output of 2.4 Amps, which is perfect for charging larger items like your tablets. It can also be used to charge phones at a faster rate, but not all can handle the increased electrical current.

The body of the Innori battery pack is made out of a plastic that, unfortunately, does not feel very premium. Located on the top of the battery is a power button that also has four LED lights that are used to indicate that the pack is on as well as displaying how full the battery is. Additionally, there is a microUSB port on the side of the unit that is used to charge the battery pack.

One of my favorite features about the Innori battery pack is that it can detect when you have plugged a USB cable into one of the ports and will automatically turn itself on. If for some reason you unplugged your phone but left the cable in the battery pack, it was smart enough to turn itself off in a matter of seconds.

Now that phones are coming with around 3000 mAh batteries built into them, you can expect to get a little over three full recharges out of this 12000 mAh battery pack. From my testing, I found that this Innori pack was more than capable of topping off my LG G4, Nexus 6, and my girlfriend's iPhone 6 after a full day out of the house. Of course the phone that was plugged into the 2.4 Amp USB port recharged the quickest, the other two phones charged no slower than if they were plugged into a regular AC outlet.

Purchase the Innori 12000 mAh Battery Pack

The Innori 12000 mAh battery pack is available right now on Amazon for only $20. Inside the simple cardboard box that is mailed to you, you will find the battery pack as well as a pretty cheap feeling USB to microUSB cable. This is used to charge the battery pack and can be used to then charge devices that use microUSB. While I do own several other battery packs, this is the battery that I plan to keep in my backpack permanently because it is so small and packs a lot of juice.
