Great option for extended reserve power with some definite design flaws/drawbacks - ATN Extended Power Battery Kit

I bought this for my Thor 5 640 thermal scope, particularly to extend battery life when it's cold, which it tends to be during deer season. The biggest drawback with this is that the pouch doesn't have a grommet to pass the charging cable through, which makes getting the battery into the pack difficult due to the tight fit. The kit I bought didn't come with a coiled cable like the image in this product description shows, but I have plenty of shorter cables that work just fine. The round passthrough rubber grommet doesn't fit the Thor 5, it would have been nice at the price point for this to include grommets that work for their latest line of thermal scopes. The best thing is that the kit I received has USB-C on the battery pack, which can be used to charge the pack and scope. The 20,000 mAH battery has plenty of capacity to add additional operational time to the Thor 5's already good battery life. Took a little bit of playing around with the straps to get it to fit on the Magpul Hunter stock with a mid-height cheek riser, but it will do the trick. For what it is, it's a little expensive, a guy could get a generic 20,000 mAH pack for a quarter of the price and keep it in a jacket pocket just as easily, I suppose.
