A detailed comparison of three ultralight 10,000mAh batteries—the Haribo gummy bear, Nitecore NB10000, and Iniu Pocket Rocket—reveals that while the Nitecore is the lightest and most energy-dense, it has practical drawbacks like overheating and lack of a built-in cable. The gummy bear offers good value with a built-in cable and reliable performance, making it a preferred choice for backpackers, while the Iniu provides a balance of weight, capacity, and versatility, earning it the author's top recommendation.
Researchers at Boston University have proposed a new charging scheme for quantum batteries using rectangular hollow metal waveguides to overcome environment-induced decoherence and charging distance limitations. By leveraging principles of quantum mechanics such as entanglement and coherence, the study aims to achieve stronger charging power, higher capacity, and larger work extraction compared to classical batteries. The proposed quantum battery model utilizes waveguides to mediate energy transfer between the battery and charger, addressing challenges related to decoherence and charging efficiency. The research opens the possibility of remote-charging and anti-aging quantum batteries with improved effectiveness and durability, paving the way for lighter and thinner devices with greater facilitation.
