Temperature adjustable. There is a device that allows you to switch between off, low and high modes. You can change the temperature by adjusting the controller to suit your different needs. |
Long-term use with power bank. It keeps the lens warm so that no condensation build-up. Perfect for any night time long exposure. Effective to keep dew or frost away from your lenses. It seems to work well, even if the outside temperature is quite low. |
Long power cable. The cable was long enough to reach the ground with the tripod fully extended, so you can use a heavy power bank and place it on the ground or put the power bank in your pocket. |
