The INNORI power bank is a super high capacity unit offering 22,400 mAh of power. As a point of comparison, the battery in my Samsung Galaxy S5 is rated at 2,800 mAh. That means that the INNORI universal power bank can recharge my phone's dead battery 8 full-times. If you don't let the battery totally drain, more likely you'll get 9 charges out of it. And, that's only if you charge the one phone with it.
The INNORI model has 3 USB ports. 1 is rated at 5V/1A output, another at 1.5A, and the third at 2A. A tablet typically needs the full 2 A output to recharge, whereas most phones are good with just the 1 A.
Spec-wise, the unit weighs just under a pound at 442 g. It feels heavier but that is only because all the other power banks I've worked with don't hold as much mAh of power and are more compact. It measures 3.15 x 0.87 x 6.3 inches. (If you look on Amazon, all the measurements are off by a factor of 10. It is not 63 inches long, for instance.) The power bank can also serve as a flashlight with a quick double click on the power button. I guess it can serve in a pinch, but it isn't very bright.
In addition to white, the unit comes in a baby blue color. Personally, I don't find this shade of blue appealing for a power bank, but you might like.
Overall, the INNORI power bank is a very capable model with its 22,400 mAh of power. For a power bank, the just under a pound weight is heavy, but that's what you need to get all the power. As long as you can store it in a backpack, laptop bag, or luggage, it will serve you well. It isn't compact enough to keep in a pocket. Competitively priced at $34.
