The Jackery 20.8Ah PowerBar weighs 750 g (1.5lb) and can power up to four devices simultaneously via in-built AC, USB-C and Qualcomm Quick Charge 3.0 ports. The UL certified 18650 lithium battery can recharge a Apple MacBook, 1.5 times; Microsoft Surface pro 4, 1.6 times; iPhone and Android devices up to eight times; and a GoPro, eight to 10 times.
The 77Wh capacity deliberately falls under the US Federal Aviation Administration’s safety limit of 100Wh for transporting on aircraft.
The heart of the design is a smart battery management system that allows the PowerBar to adapt to optimal voltage levels for each device when powering, and continuously manages inflow and outflow to ensure that both the device and PowerBar operate in the most efficient way.
“We want to give everyone the ability to charge all their devices without the need for a wall outlet. The PowerBar has passed strict quality control tests and is the ultimate power-up companion for work or travel,” said Zhongwei Sun, CEO of Jackery, which was founded in 2011.
