ANKER Prime 12,000mAh 2-Port 130W Powerbank

Performance-wise, the device operates as advertised: it does 130 watts total output, with 65 watts max per port. My old MacBook agreed that it was being charged at 65 watts, while my phone drew between 4 to 10 watts. Don't be surprised if you see the wattage fluctuate because it won't stay exactly pegged at 65 watts, or whatever the max draw is of your connected device. My only real-world testing so far is simultaneously charging a 2019 MacBook from 80 to 100%, and an iPhone from 65 to 100%. It did the job in a little less than thirty minutes, and depleted itself to about 8%. The interface is simple and easy to navigate, and the bank feels like the perfect shape and size in the hand. However, for its size (the dimensions listed are accurate) and weight (365 g), I agree with another reviewer who said this thing feels like it could/should have a higher capacity. The first screen you see after pressing the side button is either the overall battery charge (if nothing is connected), or the following (if you do have a device connected): percentage of charge remaining, battery remaining in hours and minutes, and the wattage going through each USB-C port. The second screen shows overall battery information: health as a percentage, number of cycles, and the battery temperature in degrees Celsius and Fahrenheit. The third and fourth screens let you choose the screen timeout (30 seconds, 1 minute, 5 minutes, 30 minutes) and the screen brightness, respectively. Then you're back at the first screen. It's also worth mentioning that the power bank I received indicated it already had 12 cycles on it, and I assume that's just part of testing before it left the factory. This thing loses a half-star because the more I think about what that other reviewer said, it does feel like this could have more juice, but you clearly know you're buying a 12000 mAh power bank. It loses another half star because it has that same glossy piano-black plastic that you see in cars -- which looks good, but also scratches if you so much as look at it the wrong way. That said, it does come with a fabric draw-string bag for storage. Update: I had to order a replacement because one of the charging ports on the original wouldn't work at all for charging the device, and would display a "UVP" (undervolt protection) error. The replacement device is able to recharge via both ports, no problem. Also, the replacement device arrived with 0 cycles on it, whereas the one I originally ordered had 12 out of the box. Anyway, Anker customer service was great in helping me diagnose the issue and suggested I could return it via them, or through Amazon.
