    Bought this item because it's a great price for the 10400 mah you get but i ultimately returned it. Loved the digital readout but it took forever for my iPhone 6s Plus to charge with it. I left it charging for over 30 minutes the first time and my phone had only increased 3%. I tried it again and it was barely faster. The phone was charging at 0.6 volts which is really slow. It could have just been my experience with it but I wouldn't recommend it.

    This is a great product for the price, a few nice fetures are the readout on the front telling how much juice is left, the dual plugs, but my favorite feature is the charging port to recharge the pack is in a location that doesnt have any angles or curves, meaning it wont slowly break its self just from charging it.

    This was given to a family member getting ready to head off to college in the fall. She seems to be very happy with it and will find it useful for phone or tablet while in school. We have yet to evaluate if it has the multiple charging power it advertises so I cannot comment on that yet.

    We took this to Walt Disney World to keep our phones charged. We had one issue with it, where it would not turn on, even though it was suppose to have 50% charge. After plugging it in at night, it jumped to 55% and charged to 100% over the night and worked perfectly the rest of the vacation.

    This is the second one of these storage chargers that I have bought. I bought a solar charger and I tried several different portable chargers to collect the charges and to recharge my devices and this one was the best. I especially like how this device show the percentage of charge.

    This was definitely a must have in our recent trip! The cameras battery wouldn't hold up for our day-long adventures so this came to the rescue every day!

    Great portable product to keep as a backup charger. Unlike some other 10000+mah batteries these are pretty light, weight wise.
