I have used various battery packs for hunts for many years. I have used brands such as Anker, Dark Energy, and various "China" brands from Amazon. I have yet to find a battery pack that gets anywhere near the advertised charge capacity. For instance, a September Archery hunt in WY, I brought with a 50,000 and a 40,000 mAh power banks from Amazon to charge my iPhone 16 Pro (3,582mAh Capacity) and a Garmin Inreach Mini2 (1,250mAh Capacity), which is about 5,000mAh Capacity between the two electronic devices. This would mean the 50,000mAh should be able to charge both devices 10 times, and the 40,000mAh should be able to charge both devices 8 times. In actual practice, the 50,000mAh was able to do each 3 times, and the 40,000mAh about 2.5 times. This was more than enough "juice" for my needs, but if these packs were at, or at least "closer" to advertised capacity, I would only need to haul one device vs 2. The Anker seems to be closer to advertised capacity, but still no where near what the label claims. I understand the cold will hamper the battery capacity so I try to keep them in a bag wrapped with clothing the best I can or in my bag at night while sleeping and charging devices. Does anyone have recommendations on Battery Packs that are darn near close to their advertised charging capacity?
