    Impressive capacity for extended vaping sessions, reliable performance.

    I recently got my hands on the AW 21700 4000mAh Battery, and I'd like to share my experience using them.

    Firstly, the 4000mAh capacity of these batteries is quite impressive. It provides a substantial amount of power, making them suitable for high-powered vaping devices and extended vaping sessions. With these batteries, I found that I could go through a day of vaping without the need for constant recharging.

    In terms of build quality, these batteries are well-constructed and feel solid in hand. During my usage, they performed consistently and delivered a steady supply of power to my vaping device.

    However, it's important to note that these batteries have a 21700 size, which is less common than the standard 18650 size. While they are compatible with a variety of devices, it's essential to ensure that your specific vaping device can accommodate 21700 batteries before purchasing them.

    Additionally, these batteries have a flat top, which may not be suitable for devices that require button-top batteries. Compatibility with your device is a critical factor to consider.

    Overall, the AW 21700 4000mAh Battery is an excellent choice for vapers seeking high-capacity batteries for extended vaping sessions. Their impressive power output and reliable performance make them suitable for a range of devices. However, their less common 21700 size and flat top design mean you should confirm compatibility with your vaping device before making a purchase. As with any lithium-ion batteries, proper handling and charging practices are essential for safety.
