    This works well and charges fast. I used it on vacation and it lasted the whole way there and back (since I only used it in the car).

    We frequently go to long car rides and kids often complain about their ipad and nintendo switch run out of battery so quickly. Once the battery drains, it is so hard to recharge ipad or nintendo switch in the car. I purchased this product to try out this time. It works great. iPad charges much better. No more cries about 1% charge left. Make sure you plug in ipad cable to quick charge usd port (reddish one) and click on power button ( only button that you cant miss). For charging, i recommend usb-c charger like it comes with nintendo switch or macbook pro. The cable comes with is ok but not adequate for quick charging. Once it charges quickly, blue light will be on and blinking light will show the progress. I had no issues charging ipad, nintendo switch, macbook or iphone. It does a great job. If you have kids and long car ride, I recommend this product.

    I bring this fast portable charger everywhere. It can charge my 4,000 mAh phone battery fully around 2 times or more on a single charge. Great for travel or camping where you'll need extra energy.

    It’s so good, my husband keeps taking it from me to use at work. During our week vacation it kept our iPhones charged without having to recharge the battery pack. It has some weight on it, but great quality. Will buy a couple more so each person in the family can have their own.
