      I've been wanting to purchase this power supply for some time. So, when I saw that it was available I made the purchase. I was unsure about the instructions but quickly got up to speed. Charging was a breeze and I was ready to go in a short amount of time. Not sure about the lights that have any value since you want to maintain night vision but they will help at set up and when it's time to shut down and pack up for the evening. I always like to complete a test run inside before hand. The battery pack comes with a charging brick, two straps one to attach the unit to the leg of your tripod and another useful to hang the unit on some where else, and the all important power cable that attaches the unit to your scopes power. I like the fact that the power cable attaches on the outside of the power tank. I practiced doing the usual set up procedures and ran my CEGM 9.25" through it's paces and let the unit tracking for many hours until it was time to go to bed. I experienced NO problems over my test run with this power tank and am looking forward to my field tests.
