    Not good for ipad

    It took a long time to charge the battery using the large Apple usb charging block. The battery itself does not put out enough power to charge my iPad, which was the primary purpose for the battery for inflight use. I put in airplane mode and it took over an hour to put 15% on it, it actually depletes battery in the iPad while plugged to patters and using the iPad- very disappointed.

    It takes 2mins to charge 1%. This is slow charging compared to regular home wall charge. I have used older model anker powercore that charges super fast.

    I bought this charger last Oct 2018 for my trip overseas. I used it to charge my iphone XS since this is my primary camera for maybe twice a day for 6 days. Then again last Jan for another 4 days charging twice a day then after few days the charger won’t charge anymore. So it only lasted 20 charges total from 40% to full twice. So for this reason I’m not recommending this product. I wil try mophie.

    I bought the Powercore portable charger and used it a few times and now it won't charge anymore. See other people complained about the same defect.
