    What is the lithium content in these batteries? I am looking to fly with one of these, but want to make sure it is okay.
    "Up to two larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on." is the guideline

    If you wish to plug it into the wall, what do you use? I see it comes with a cable, but no adapter? Should I use my iPad charge adapter? That is 2.4Amps and 5.2V, I believe, but this says input power is 2.0Amps and 5.0V.
    Michael D on Mar 26, 2017
    BEST ANSWER: Thank you for your question. It would be recommended to use a 5V/2A wall charger. You could use the 5.2V/2.4A wall charger but over time it could decrease the longevity of the battery. Also you can charge it with a 5V 1A/1.2A charger or via a computer but the charging times will take longer with lower amperage. I hope this helps.
    20000mah will not charge or charge other devices. Only flashes 4 bars then 3 then goes off. Is there a way to reset? Trying to run battery down with led light to see if it will reset. . Been on for a week straight now and has not killed the battery. I bought this for tripped I'm dieing without it.

    BEST ANSWER: Hello, thank you for your question and I am truly sorry for the inconvenience you're encountering with the item. Have you already tried a different set of devices on it? What about a different power charger? If you were within the 1 year warranty, we can replace it if those solutions do not help, please let us know. Thank you!
    Will it work on an iphone7?
    A shopper on Jan 24, 2017
    BEST ANSWER: YES! It will work with any USB powered device, as USB is a worldwide standard. I've used it for recharging iPhones, iPads, Kindle readers, and for recharging smaller power banks. This unit, whne fully charged, can recharge an iPhone many times, and I've quite always used it with two devices at the same time.
    It's a very good product, it's a little too big and heavy for normal pockets, but I carry it in my backpack without problems.
    I have the 15123 charger. What is the purpose of turning on the led light on the charger?
    James M on Mar 25, 2017
    BEST ANSWER: I assume you are referring to the single LED light in front of the charger. That light is like a small flashlight, if you ever happen to be in a dark place without any other source of light. Double click the side button to activate/deactivate.
    Would I have to press a button to start charging my devices or do I just have to plug them in? I'd like to use this as a battery for my dashcam in my car. So I need something that would recharge and power my device at the same time while my car is on. When I turn my car off, I need it to still supply power to my device without any additional interaction from me.
    Daniel P on Feb 11, 2017
    BEST ANSWER: Hello, thank you for your question. This unit does not have a power button and will charge/power your devices as soon as they are plugged in. I hope this helps, and of course if you have any more questions feel free to contact us!

    Liked it, then it died
    This was the first power bank I've ever had. I was really liking it until it just stopped working. Won't charge any devices. Lights come on, I can't charge it. But when I plug a device into it it flashes like it has no charge. Flashlight works, tried with different cables. Don't know what the issue is

    Battery fails to charge on multiple chargers
    Battery fails to charge fully and sits at one blinking light after a few weeks of use.

    Love these battery packs
    This is the second one of these I have bought - the first one is still going strong. They go for about 5 times the price at your local electronics retailer. It will charge anything you can plug into a USB.

    Great unit
    I just used on a 30 hr international travel & it kept phone charged as well as a few other people's phones & ipads & only about half of it's charge.

    Value and reliability in one convenient package.
    Product works well- long lasting. I appreciate that it can charge two devices at once. Remember that if it can charge an iPhone ten or eleven times then it will take ten or eleven times longer to recharge but the price and reliability make it completely worth while.

    Bigger than expected, but awesome
    This is a really nice charger. 20000mAH is a lot of juice!

    Works well
    No complaints so far. It works as advertised. I don't use it much so 20000mAh was a little overkill, but I got it on sale!

    Large but powerful
    This battery is BIG, and fairly Heavy for a backup battery but you can charge your phone and tablet several times over with this power cell. Never worry about needing to charge your phone if you have this with you. Can provide five or six charges to larger devices with how much power this holds. I would recommend this to anyone.

    Great product! Provides multiple charges before needing to recharge the unit. Would highly recommend for value and quality.

    Fantastic charger.
    Unbelievable charger and value. Just back from 4 days in Vegas. Had this in my pack and charged my iPhone and my friends Androids with no issues and only used two bars in our busiest day. Less then $20 for this charger is beyond value. You would pay double for a similar charger with less power at big box chains.
