    I have used the 20,000 PoreCore on my IPhone and iPad and it still has charges left. Feel confident that my system has sufficient charges for even more devices as we travel.

    I bought this battery pack on the day of my trip to Las Vegas, which was an 8 hour trip. It kept phone and other people’s phones charged all day. Definitely getting myself a second one.

    This is a great battery bank, I was able to charge my iPhone 7 at least 6 times before a recharge. Although it has been a reliable device, beware of a few drawbacks. It takes a very long time to charge and no USB-C. Overall, it’s a great device, just make sure that you can live with the long charging time and the lack of USB-C

    In my case this has far exceeded the expectations! Brought my Lenovo C930 from 10% to 95% twice in one day + recharged my S10 phone and still had juice left. I'm sold on it.

    IT PROVIDES A COMPLETE CHARGE FOR MULTIPLE DEVICES AT LEAST 2 SEPARATE TIMES UNTIL IT NEEDS A CHARGE. I WOULD RECOMMEND CHARGING THIS EVERY 3 DAYS. DEPENDING ON AMOUNT OF USE.
