    Great but comes with wrong adapter

    It is very thick and rugged. I have only had it for two months and used it 3 times and I love it. It charges fast but you have to charge it for the full time amount. It does have a partial charge right out the box so the light did work. Yes it actually is water proof. I regret to say that I have actually spilled water on it one time and it still works fine. I dried it thoroughly with a towel and waited a day to use it again. The only problem I have is if it says its made for iphone 7 like mine is then why doesn't it come with a mini plug in that fits my phone Iphone 7. Instead it comes with a usb plug which will NOT plug into an iphone 7. so if you want to use it you will have to buy an adapter or use your iphone charger as an adapter for this. So Annoying but it works great.

    My first charger stopped working well after just 2 uses. The cord and charger have to be perfectly horizontal in order to be charged or to charge the phone. Once you move the cord, it stops working. So far so good on the replacement. The cord is very short so it's not very convenient to use the phone while charging. Other than that, it does a great job charging my phone when it does work. Works fast and charges the phone fully.

    I love this product, because it is durable and has a really good battery life/charge. It is supposed to be water and sand resistant, which is also very important. The flashlight is very bright. It is compact and easy to be carried in the grip of your hand. The cord could be a little longer and the plastic housing of the micro USB could be a little smaller to fit cell phone cases.

    Used this battery while a friend was in town...it worked beautifully in Disneyland, Universal City and Catalina. As a security geek, I know better than to plug into strange ports so I was glad this battery worked so well. It's shock and water resistant and has a built in flashlight.

    This was recommended by the Teachers at my son's Middle School for their 8th grade trip to Washington. They spent a lot of time walking and site seeing and this charged his phone when away from an outlet. It came pre-charged with enough juice for 2 charges which was an added bonus.

    I purchased this charger based on what a staff member told me. Unfortunately it did not live up to my expectations. I used it for only a week and piece from the top part broke off. It took a long time to charge my smart phone. Very disappointed in this brand!

    I would recommend this for you cause it's great to have especially at night. It doesn't cost that much but it's good to have. The good thing about it it's waterproof. I am going to get another one. They have several types of them.

    I bought this portable charger for my wife due to her phone dying multiple times a day. Needless to say it still dies but that is not due to this product. If your in the market for a portable charger then this is the product for you.

    Bought this to withstand wind, rain, and frigid weather supporting the Secret Service at the Inauguration. Worked great after being up at 2 am and working all day. Flashlight integrated in waterproof case came in handy also.

    I used this once for my smartphone in an airport. It seemed o charge quickly. My only complaint is it’s a little hard to see where the power button is and the directions are pretty minimal. But t seems to do the job,

    I have had no problems with this device so far. It has worked both indoors and outdoors (although the frigid air did effect its length of time) but it charged my phone or kept it alive every time I've used it. Love it!

    Bought this to use on a trip. I got about 3 full charges out of it before I had to recharge. Indicator lights are way helpful in seeing how much charge you have left. Flashlight is a bonus.

    We bought this as a larger power source for a tablet to complement the smaller version we bought for the phone. It worked very well over a weekend where wall charging was rarely available.

    I am happy with the product. I can carry it with my LG G4 phone, though it is a bit bulky. It might be difficult for someone to carry if they have smaller hands -- or more arthritis -- than I do.

    This charger works great for my needs and the flashlight is a very welcome feature. The included usb cord was bad though, it would only work if i bent the cable. I bought a separate usb cord regardless.

    The reason I give 3 stars is because I have not tried it yet in a real need situation but I will soon and I will update my review. But so far is still charged since I charged it like a month ago :)

    It does the job. I'm in construction so the shock proof I need (in case I drop it). It's 4000mA. I have a s6. It charges it maybe 2, maybe 1.75 times. It gets me through a 10 hrs shift just fine.

    I bought this after checking out other portable chargers. Dis does very berry good. Should have gotten one for 2 devices and longer charges but this one will do the trick for starters.
