    The USB-C cable inside is very handy. I have never used a power bank before so it was simple and easy to use.

    This thing is a beast! Charged my phone, charged my bluetooth speaker and charged my square reader all at the same time. Rapid re-charge all at once. Still plenty of juice left in the tank. BEAST!

    Nice power bank. On the heavy side but lots of power. Used on a dew heater for my camera lens to keep the frost from forming in 12 degree weather while photographing the recent meteor shower. My supposed 10,000 mah pack lasted less than 4 hours at room temperature when tested with the dew heater. This one used less than 1/4 of the capacity in 5 hours at 12 degrees. Quite happy with the results. Frost on everything but my lens.
