Calibre 2500mAh quick charge battery with vibration indicator for iPad

The elegant and smart quick-charge battery with 2,500 mAh comes in a sleek design and compact size. How small is it? Slightly smaller than a credit card and exactly one centimeter thick. This means it fits perfectly in a blazer or jacket pocket without adding bulk, making it truly compact. It is excellently crafted and simply exudes quality! The only openings are located on the right side, featuring a microUSB port for charging the battery and a USB port for charging your smartphone. On the top, there is an engraved Calibre logo with a small LED that indicates the charging status. This LED light pulses when the battery is charging and remains steadily lit once it is fully charged and ready for use. If you want to check the current charge status on the go, just plug in a cable, and the innovative battery will vibrate - 4 vibrations for 100% full, 3 vibrations for 75% full, and so on.
