    Absolutely zero problems with this product. I've taken this on many vacations the last 2 years I've had this and it has never disappeared. Great buy indeed!

    I need extra battery charge for my phone during the day. This supports that easily so then I tried it on the tablet. Works great. Next on my all-in-one computer, again works great. Does what I needed and more.

    Great large capacity - up to 7 phone charges or 2 tablets. Bought it as back up for a hurricane multi day power loss. Also great for tailgates when all the guests want a top off before going into the stadium.

    This device is awesome. I took it on a trip to Mexico and it worked great. It charged my phone, my camera, and my go pro. It’s a little bulky but worth it. Charged everything I had and still had juice left

    I Iove this portable charger. I took it with me when I went to Coachella and I was able to charge my phone several times without having to recharge the charger. I love it so much I am buying one for my daughter.

    I literally don’t leave my house without it! The two ports make it great to share the charge with other people and it really does last a while before you have to charge the portable again!

    Great charger, holds for multiple days depending on your usage and number of devices. Only con is it takes forever to charge, I left it overnight around 6-7 hours and it still wasn’t done.

    I have only used this once at Universal studios and was able to get 2 charges to an IPhone throughout the day. Wasn’t full charges as my friends would use it for like 45 min at a time a few times, but even after that and leaving in drawer for a week, still at full status. Out of box it was at 2 dots, 4= fully charged and took a couple hrs to charge from the halfway point.

    Fits great in a backpack or suitcase pocket. Convenient to use charging multiple devices all at once. Would be perfect for camping. Whenever its a challenge to find charging this works.

    Definitely provides quite a charge. When i'm out and about, I can charge both my Samsung galaxy S9+ and LG bluetooth headphones to full charges several times without having to worry about finding an AC outlet.

    Used it several times, but it never went below two lights! Charged it anyway and it's still almost full two months later after three uses! I've been skeptical about these chargers, but this is great!

    We travel all the time and between three of us we needed a charger that lasted and charged all our phones. This one does that!! We can all charge our phones to a full charge at least twice with one charge.
