Katinny Portable Power Bank 10000mah with dual exports 1 flashlight (White)

Got a white one and it looks very pretty and elegant. The size is just about right and easy to carry around. Charging is fast and safe and would definitely recommend to everyone.

It's a very nicely designed portable charger and it is convenient to carry around. Recommend it!!!!!!

This "Piano Keys" 10,000mAh external battery charger from Katinny seems very well constructed and is priced very nicely as compared to others with this same, large capacity. It is larger, though still of a convenient size at about 5.5 inches long, 2.5 inches wide, 1 inch thick, and weighing in at about 9.5 ounces. This backup battery is an easy carry in your back-pack, brief case, or duffel bag and you travel and it comes with a micro USB cable that allows you to plug it in to your wall power adapter unit for charging.I tested this battery using an HTC Droid DNA and my son's Samsung Galaxy S3, and it performed well.Upon receiving the battery, we plugged the unit into our wall adapter and three of its blue LED lights came on (of four total lights), signifying that it was about 75% pre-charged at the factory. We let it charge for a couple hours and came back to check, and it was fully charged.Operating this battery is a very easy -- the two phones we used in our test have micro USB ports, so we just plugged the supplied micro USB cable in to each device. This battery is not in 'always on' mode, so you have to make sure that you press the on button on the battery's case after connecting it to your phone. For for devices that did not have micro USB ports, like our daughter's iPhone 5c, we would just use the cable that came with her phone to get the job done. Simple, easy and effective.The storage capacity of this battery is 10,000mAh which is huge for our needs and would be perfect for charging the devices we have a about four times over. It is just great for emergencies and excellent for for a long getaway weekend too. The charging times we experienced were average - about the same as many 1A wall chargers -- on average it charged our units (with their 2200 - 2600 mAh batteries) at a rate of about 1/2% per minute, or about 30% recharging per hour, from its 5v 2.1A USB output port.The battery pack did not get hot when being charged or when charging the phones. While charging, the blue LED lights actually stay on to provide and indication of how much juice is still left to be used. The lights are easy to see, and the power bank is easy to use. The integrated flashlight is not bright at all, but might provide enough glow to help you get your key in the door lock on a dark night.The Amazon listing notes that Katinny covers this battery with their "30 days money back and 12 months worry-free product guarantee", so if an issue arises within that timeframe I will return here to update the review and let you know what the issue was and how resolution was handled. I did receive this battery gratis from the seller and put it to use to objectively find out how well it performed. My statements here reflect that testing.We found this Katinny Piano Keys power bank to be stylish, effective and easy to use, and it's 10,000mAh battery does the job as described by the manufacturer in very quick fashion. If you are looking for a battery pack of this capacity, size, style and charge rate, for use as I have described above, then I recommend giving this one a try based on our experience with it.Recommended.Go for it.

I was provided a Katinny Piano Keys 10000mah Power Bank (White Version) free for testing and review and was asked only to give my honest review, so this is what I found.What You Should Know Before You Buy:♦ Medium sized power bank with a 10000mAh capacity. About the same size as an iPhone 6 and about 3 times thicker.♦ Has two charging ports (a 2.1 Amp and a 1 Amp) for simultaneous charging of two devices.♦ Unique piano keys design with white unit and three black panels that look a little like piano keys. If it wasn't labeled as "piano keys", I would have just thought it was a random design.♦ Large capacity that has plenty of power to charge a phone 3-4 times and an iPad most of the way.♦ Good charging speeds as compared to competing power banks for both iPhones and iPads. Added 9% in 10 minutes to an iPhone 6.♦ Has a built-in flashlight.Conclusion:Overall, the Kitinny Piano Keys Power Bank worked well. It has a large capacity and two USB ports for charging. It has a "piano keys" design, but if you aren't into pianos, it can easily pass as just a random design. I tested the power bank with my iPhone 6 and iPad 2 and both charged just fine. The power bank added 9% charge to the iPhone in 10 minutes which is a in-line with other power banks. It also has a small LED flashlight built in which could come in handy in a pinch. If you are looking for a larger capacity power bank with a unique design to charge your phone or tablet, this one is a nice choice.

Fantastic Product! Honestly, this is a product that I figured I would try out just because. Now, that I have it and have used it I come to realize that I love it and wonder how I every lived without it!It is the length and width of my Samsung Galaxy 3 and its double the height; it kind of looks like the battery of a laptop. The top is just like how it is shown in the picture; it looks like piano keys. I think its cute looking. As long as I have a purse that my phone fits in, I know that the charger will fit as well.It takes a while to charge but the four lights do indicate the life of the battery so if you dont need it to be fully charged you could carry it and just use it as is. I mainly carry this for my cell phone and my bluetooth and I am able to charge my phone to 100% (usually from below 10%) about 2x and my bluetooth 2x as well. Also, it has a mini flashlight on it, and you could use it while charging or not.Note: I received this product at a discount in exchange for my true and unbiased review.

How I love power banks that can give my HTC One M8 two full charges. It means I can use it once and not have to worry about recharging the power bank right away. If I'm busy or away from home, I still have another full charge for my phone when I need it. The Katinny Piano Keys power bank does it, and it can charge two devices at once. Just today, I charged my phone and my Kindle Fire HD 8.9" tablet together without a problem.Some cons: The glossy surface mars easily, as these types of surfaces usually do, and the power button is easily triggered in a purse. I've opened my purse to see the power bank's flashlight on, an annoyance I prefer not to have.This product was provided for review by Katinny.
