iWalk Duo UBO3000 3000mAh Rechargeable Backup Battery with Built in Lightning and Micro USB Charging Cables, Gold

Well it's not a powerhouse - After all is only 3000 MAH, but it works great and will give me almost a full charge on my iPhone 6s. MFI certified so it works with my iPhone with no problems. Ability to use the mini USB cable to charge my headphones and other non-Apple devices is great. Product is small, thin and extremely good-looking -- almost sexy.It works intuitively. (Although it did take me a few minutes to figure out it's one tap on the power button to turn on; two taps to turn off.) The power indicator is bright bright blue, so that could be a plus or minus depending on your preference. Having the LED is handy to ensure it's on, and have a quick power readout.So far so great. I'll update as I use it more.UPDATE 5/9/18 - Two years later, this goes with me everywhere in my messenger bag, in my luggage when i travel, and in my coat or pants pocket when i expect to be out all day. It still works flawlessly, and has saved me from a dead phone many times.UPDATE 12/15/18Stopped working after about 2.5 years, which is unfortunate so I’m taking off a star on my 5 star rating

It had a long battery life, like almost two charges of my phone I think, it was thin and portable, it was very nice. One complaint was the blinking blue light while charging was annoying if it was dark in my room it would light up the whole room but that wasn’t a big deal. The problem was after like 7 weeks the power button was permanently pushed in, even though I was always very delicate with it and had a special pocket in my purse for it. The return window closed after 30 days, but they made an exception and gave me $8 (not my original $10) back. But I used it for 7 weeks still at least. I am going to put that $8 towards a better quality one that will last years instead of weeks.

My daughter has an insulin pump constantly connected to her body that she has to carry around in a pouch. She also carries an iPhone in the pouch that communicates her blood sugar to me and her father. Both need charging and we are constantly looking for the different cables and chargers. Now this little charger can fit in her pouch and she can get an emergency charge. I love that the cables are attached and that the charger is so thin and light. She doesn’t even notice the weight. Perfect for a type one diabetic who has to carry a million things.

The unit is incredibly lightweight, fits easily into any pocket or bag. I got multiple charges from this after one full charge. It makes my life easier if I’m working a 12 hour day with no access to a charger cable.

I use it to recharge my iPhone and keep it in the same pouch because it is so small. You can also use it to charge your iPhone overnight when you charge the battery by connecting your iPhone at the same time. I bought 3 if I need more power but seldom do.

Perfect for the family. Just what we need. My grandson begged me for the first of course I said no. I order 2 more & surprised him & my son. Now we have our own 1. Very. Very Thank u.Oh y do u guys only have 1 color different colors would have helped.

Didn’t seem to work well. Maybe I was expecting too much. It didn’t hold the charge very long, therefore my phone never got the boost it needed.

It portable charger won’t turn on anymore, the only way to get it to turn on so you can charge portably is to plug the portable charger in like you would charge it and that turns it on then you can unplug it and plug your phone into the portable charger to charge it. It is Horrible.

This is a really great charger. Can charge a phone and still have left over power in it.

Received as described and very quickly. Works great and my daughter is very happy.
