    Worked really well! Charges faster when you charge 1 device at a time; worked well in the backcountry at the Grand Canyon, slightly slower charge due to the heat

    Great product! Used it to fully recharge 3 phones in less than an hour, and it has only used 1/25 of its stored energy. Highly recommend!
