The RAVPower 20,000mAh power bank delivers ultra-high capacity, providing approximately 4.5 full charges for the iPhone 15, up to 3.8 charges for the Samsung Galaxy S23, and around 1.2 charges for a MacBook Air. Designed for convenience, it features four charging ports, allowing you to power up to four devices simultaneously. A built-in smart display keeps you informed of the remaining battery power at all times, so you’re never caught off guard. Despite its high capacity, the power bank remains compact and lightweight, measuring just 4.25 x 1.97 x 1.89 inches and weighing only 0.79 lbs, making it perfect for travel or daily use.
