bPowered UP Power Bank – TRUE-12000 mAh-Dual USB- Premium Ultra-Thin Portable External Battery Charger- Compatible w All iPhones, iPads, Android, etc

I have had two of these units myself since Christmas, and BOTH have failed. The port to charge is simply poor quality. I have been very gentle and careful with the second one, since I know the weakness from the first unit, but it didn't matter. The port just pushes inside the unit, and it's no good. The company was easy to deal with when I asked them to replace the first unit, but the exact same problem has happened to the second one. JUNK! I do not want another one, and I am very sad that I bought them for my family for gifts!

I'm so glad that all the 5-star reviews about this product are true. This power bank really has a huge capacity. It charged my Samsung S7 from 15% to 100% twice, and both times were under 2 hours, I believe. One time, I charged it from 20-50% while it was charging my iPhone 5S, simultaneously. All of these happened, and it's just now that my powerbank ran out of battery (I'm charging it now, and it's almost full already but I've only been charging it for 4 hours. 4 hours only!). I am confident that this powerbank will definitely last me for a few days if I take it with me on an outdoor trip. Thanks so much, BWise!

I've had it for only 2 months and the charger micro usb port has broken inside the charger. I don't think I can crack this thing open to fix the port so it will basically die and then I won't be able to recharge it. Useless

As others have said, the product itself -battery- and packaging are amazing. The battery has a nice heft with a great exterior, charging speed is as expected. The reason for the 3* review is because of the cord. Not one, but TWO, of the aluminum head covers slipped off as I unplugged my phones. I have not tested the 3rd as I no longer have older gen Apple devices. I plan on gluing them back onto the head of the charger, a simple fix, but this should not happen in a product at this price range.

BOMBASTIC POWERFor the price, this is a true backup when you are out and about so as to not have to find a power source to plug in your phone or other devices,I couldn't be happier.When I go somewhere that I have to wait I like to play games on my phone, but games are a power drain. This solves the issue. Since it is the size of a large cell phone, it easily fits in your purse, The ports (connecting cords) are extremely sturdy.I was also impressed by the pristine packaging it came in, a nice study "gift box" of sorts..could easily be a nice office gift.

This is a great battery. I bought it for my wife and she loves it. This size is perfect for keeping in her purse without adding a lot of bulk or weight. A few months after we got it, the micro-USB port came loose inside the battery. I contacted bPowered Up and they couldn't have been nicer. They shipped a new one right away, and it arrived in five days. Michelle emailed at each stage to make sure we were informed. Phenomenal customer service! I'll be going back to this seller for sure, because these male great gifts.

For my battery in a Samsung Avant it won't charge 8 times. I think if you turn the phone off and let it charge you might get 6 charges with a battery of the size of the one in the Samsung Avant. It will give you about 4 charges if you are using the phone alot while charging. I listen to music a lot while charging or browse the net, so in my opinion it does what I want it to do. If you have a small battery like in an old flip phone you will probably get 8 or more charges.

Just came through Hurricane Matthew and really used this charger for the first time. It recharged the cell phones x 4 and still had 3/4 of the power left. And it is very fast- less than 1 hour to recharge a phone on 40% battery. I am going to get another one of these as a backup. This is by far the best charger of its type that I have used.
