    How long does a charge last?
    Katherine W on Feb 2, 2017
    BEST ANSWER: This depends on your device. You can assume this battery bank has an actual capacity of about 90% of its actual rating, so let's say it really has 2,250 mAh. Then you check how many mAh your device has. An iPhone 7 has 1960 mAh and you can assume that charging isn't 100% efficient, so this bank will charge an iPhone 7 about once. However, iPhones tend to have lower battery capacities than flagship androids, so if you wanted to charge a Galaxy S8 that has 3000 mAh battery, you can assume it will charge only about 66%. Best to check your specific phone's mAh specification.
    What do the flashing lights mean - Charged? Charging?
    Rich B on Dec 5, 2016
    BEST ANSWER: Lights flash red, then yellow, then green as it's charging. Once you get a solid green light, it's fully charged. A solid yellow light-- still some charging power left but not fully. A solid red light-- time to charge the unit.
    how many charges for an iPhone?
    A shopper on May 29, 2018
    BEST ANSWER: I usually get one charge out of the unit. The uniqueness of this product is the convenience. The iPhone plus the charger still fit in the same pocket and the build-in connector.
    What type of input does this use and how many amps?
    Lowell K on Aug 21, 2018
    BEST ANSWER: It is a Apple Lightning connector and seems to change around the 1amp rate.

    Very portable and convenient, questionable capacity
    This battery charger is for the mobile user that struggles to get through their day on one full battery. I like the battery for its simple straightforward form factor. While no instruction manual is included, the battery operates as expected. There is a micro USB input to charge the battery (cable included). A color indicator suggests whether the battery is full or low (there's no instructions, so you'll have to guess what level green/yellow/red mean). The light blinks when it's charging and (presumably) a solid green means that it's full. One thing to note is that there is no button to turn the battery on/off. There must be a switch in the lightning connector socket that indicates whether the lightning connector is tucked away or pulled out. I normally like to have an on/off button, but I can appreciate the simplicity for regular use.
    Battery operation works as expected. My main gripe is the advertised 2,500 mAh capacity. I've tested this battery on my iPhone 6 which supposedly has a 1,810 mAh battery. So, one would expect this battery to fully charge my iPhone 6 once. I've only charged my iPhone with this battery twice. But, so far, this battery will only charge my iPhone 6 by ~75% (e.g. - iPhone battery was brought from 10% to about 85%). Even accounting for real world conditions that say charging is less than 100% efficiency, I would expect a 2,500 mAh battery to fully charge a 1,810 mAh iPhone battery.
    Another noteworthy comment is directed to those that use a case to protect their iPhone. The black plastic casing of the lightning connector may be too thick to support charging with certain iPhone cases on. (I have to remove my first-gen RhinoShield CrashGuard bumper case to charge with this battery.) I have this same issue with some of the earlier/basic Monoprice lightning cables.
    Overall, this battery is good for the price. Despite its shortcomings (in my eyes), I will likely continue to use it. In fact, I bought two (during the Black Friday/Cyber Monday sale) so that I can always have one on hand while the other is charging!

    For perspective, I haven't used many portable battery chargers. But, I consider the LinearFlux LithiumCard Pro to be the gold standard. I got one from their Kickstarter campaign but, it did not survive my daily abuse of it and I am not willing to pay the cost to get another one. While it was working, I *loved* it. But, it only lasted me for about a year. For the money, I can get 10 Monoprice emergency batteries or just one LithiumCard. 'Nuff said. :-)

    Very useful, but...
    This is a great value and provides enough charge to carry me over for the day. I recommend this power pack even thought it doesn't perform up to the level I expected.

    At a 2500 mAh rating I would expect the ability to fully charge my iPhone 7 but it does not. A first unit provided ~40% charge, a replacement provides ~70%. This is adequate but not what should be expected. To charge my phone it would need to perform at ~80% efficiency, a very reasonable expectation.

    It also comes without any instructions. It is easy enough to figure out with green -> amber -> red represented depleting charge and solid green representing full charge. when charging. But, there is not a good excuse for not including minimal instructions.

    Thin battery
    Perfect size to fit in pocket with phone.
    I use a rubber band to hold the phone and battery together and it works very well.
    The battery is actually thinner than the phone and a good fit...I have a 5s

    Great!
    Love it! I bought two of them. They are super slim and really do a Grady job of recharging my phone. Would definitely recommend, you'll be happy

    Perfect for pocket or purse
    Love the small size and weight. Its easy to carry in a pocket along with your phone. It gives you plenty of charge to get you through an emergency or until you can plug your phone in. Also feels sturdy to the touch.

    Highly recommended.

    didn't get full charge but very happy
    I used this on iphone 6S. I normally get 70%-80% charge. My wife iphone 6 Plus get about the same. I am very happy with it small form and built in charging cable. I have many powerbank at home but I'd rather use this one. I put it in my front pocket and it is so light and convenient. This is a good buy!!!
