    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.
