Anker PowerHouse II

Big capacity
The 388Wh capacity provides multiple charges to virtually any mobile device. Charge an iPhone 11 (3110mAh) 23 times, a MacBook Air 2020 (60Wh) five times, an iPad Pro (30Wh) 20 times, or a camera more than 20 times.
Charge eight devices simultaneously
With a 300W AC outlet, 60W USB-C port, three USB-A ports, a car socket, and two DC ports, PowerHouse gives you the ports you need to charge all of your devices at the same time.
High-speed charging
PowerHouse's 60W PowerIQ 3.0 USB-C port can charge a MacBook Air 2020 to 50% in just over 40 minutes - that's 40% faster than with an original MacBook charger.
Stable power supply
The built-in AC wall outlet uses a pure sine wave inverter to ensure the power output is just as good as what you get at home. Reduces audible and electrical noise in fans, lights, speakers, TVs, and other sensitive appliances.
