Peak power is the maximum power the power station can sustain for a short time and is also called peak surge power. For instance, when a device with a motor is turned on, the motor uses more power to start up than it does when it is running. The PowerTitan has two AC outlets, two USB-A ports, one USB-A Quick Charge 3.0 port providing up to 18 watts and one USB-C Power Delivery port providing up to 60 watts (enough to charge my 13-inch MacBook Pro). There are two 12v DC outputs — a cigarette lighter socket that provides 10 amps and a DC6530 port that provides 8 amps. All seven ports can be used at the same time as long as the power draw from everything remains under 400 watts. There is a button for each bank of ports (AC and DC) that must be pressed to turn those ports on or off. The PowerTitan can be charged from an included wall charger or USB-C PD in 5.5 hours. It can be charged from the cigarette lighter socket in your car in seven hours or from a solar panel as fast as five hours (depending on the amount and capacity of the solar panel). The PowerTitan has MPPT (maximum power point tracker) technology to maximize the efficiency of charging from solar panels. You can keep track of the power station's status through a 4-inch color LED screen. You'll see the power going in and out (in watts) as well as the percentage of battery power remaining. There are also icons that light up to show which ports are in use. The case of the PowerTitan measures 10.2 by 6.7 by 7.2 inches, and it weighs 9.5 pounds. As for what it can power, Aukey says the PowerTitan can charge a laptop four times, keep a mini fridge running for 20 hours, charge an iPhone 11 30 times and keep a TV running for 4.5 hours. Pros: Light, integrated handle, plenty of outputs, USB-C charging. Cons: None Bottom line: It's the smallest Aukey power station, but it has big features. The larger of the Aukey Power Stations, the PowerZeus, packs a battery capacity of 518 watt-hours with a total maximum power output of 650 watts. The PowerZeus has exact same number of ports as the PowerTitan. The two AC outlets have a maximum output of 500 watts with a peak of 1,000 watts.
