Application:
Consumer Electronics
Flashlights: 21700 Li - ion battery packs are commonly used in high - power flashlights. Their high energy density allows for a long - lasting and bright light output. For example, a tactical flashlight might use a single or multiple 21700batteries to provide a powerful beam that can reach hundreds of meters. The rechargeability of these batteries is also an advantage, as it reduces the cost and waste associated with disposable batteries.
Portable Chargers (Power Banks): Many power banks are designed to use 21700battery packs. These batteries can store a significant amount of energy, enabling the power bank to charge smartphones, tablets, and other small electronics multiple times. The standard size of 21700 batteries makes it easy to replace or upgrade the cells inside the power bank.
Laptops: Some laptop manufacturers use 21700- based battery packs in their designs. The high energy density and relatively stable voltage of these batteries help to provide a longer battery life for the laptop. The cylindrical shape of the 21700batteries can also be arranged in a way that fits well within the laptop's chassis.
Bluetooth Speakers: High - quality Bluetooth speakers often rely on 21700battery packs to power their audio amplification and wireless connectivity features. The batteries can supply enough power to play music at high volumes for an extended period.
E - readers: The compact size and high energy density of 21700battery packs make them suitable for e - readers. They can provide the necessary power to keep the device running for weeks on a single charge, depending on the usage pattern.
