Same deal as half a year ago. $100 - 40% off coupon clipped from product page on Amazon. Cheaper than the comparable Koval and Anker charging bricks.

    This device is an interesting combination which may have value for some, but featured choices which could lead to interesting results. Firstly, the USB-A ports support QuickCharge whereas the USB-C ports support Power Delivery but not Programmable Power Supply (PPS). As a result, despite the wattage ratings not only will this charger not support Super Fast Charging on the USB-C, but there are likely some devices which would charge slightly faster on the USB-A ports than on the USB-C ports (because a device might negotiate a 15W PD mode but an 18W QuickCharge mode).
    • USB-C Output
      Single USB-C port output 100W Max
      Dual USB-C port output 120W Max
      Supported outputs: 5.0V⎓3.0A, 9.0V⎓3.0A, 15.0V⎓3.0A, 20.0V⎓5.0A
    • USB-A Output
      Single USB-A port output 18W Max
      Supported outputs: 5.0V⎓3.0A, 9.0V⎓2.0A, 12.0V⎓1.5A
    The power output combinations can seem complex but I've tried to capture them from the Amazon listing below:
    • When 2 USB-C ports are in use : 60W + 60W = 120W
    • When 2 USB-A ports are in use: 18W + 18W = 36W
    • When 1 USB-C port + 1 USB-A port are in use: 100W(USB-C) + 18W(USB-A) = 118W
    • When 1 USB-C port + 2 USB-A ports are in use: 65W(USB-C) + 18W(USB-A) + 18W(USB-A) = 101W
    • When 2 USB-C ports + 1 USB-A port are in use: 45W(USB-C) + 45W(USB-C) + 18W(USB-A) = 108W
    • When All 4 ports are in use: 65W(USB-C) + 20W(USB-C) + 18W(USB-A) + 18W(USB-A) = 121W
    In short, the USB-A ports always have access to their 18W maximum power rating. The USB-C ports are getting power limited:
    • When you use both USB-C, going down from one USB-C port at 100W to 60W each
    • When you use both USB-A and only one USB-C. going down from one USB-C port at 100W to 65W
    • When you use both USB-C ports and one USB-A, going down from 60W each to 45W each
    • When all four ports are in use, limiting one USB-C to 65W and the other to 20W
    Good luck!

    I don't think any of the white labeled chargers over 100W are PPS unfortunately, and not at $60. That would be ideal for me as well, but having 100W available for laptop charging and then a separate 25/45w PPS capable has been the best solution thus far.

    Thankfully for many, the number of laptops demanding 100W is becoming a diminishingly specific subset (mostly high-power systems). My first general purpose Dell business laptop with power delivery support sucked 90W (despite lacking dedicated graphics or some monster CPU), but my OLED Samsung only needed 65W and my newest premium Chromebook only requires 45W.

    Of course, that does mean that using the Spigen I could run two of those devices at full power and charge a couple of devices via USB-A... but that's simply not the solution I'm seeking for now. Instead I'll keep waiting a bit longer for PPS to further penetrate the market.

    Good luck!
