The problem I have with this is the secondary usbc is limited to 20w. The other 100w insignia charger I bought I has secondary usbc at 30w

Finally jumped as the form factor has some obvious advantages being a close to the wall design, in contrast with typical high wattage designs that hang off the outlet (essentially working to unplug themselves).

The target charging will include two phones (USB-C), a camera (USB-A), and plugging an additional low wattage charger via the accessory AC outlet.

Good luck!

USB 1.1 Type A is ancient history super slow charging. I choose a charger based on what's under the hood. Nothing to see here folks. Obsolete tech.

Edit: Thank you Jon for posting the specs. Still questioning the lack of QC on the Type A ports though.

Quote from timbertop :
Dig deeper than the form factor. Not optimized for phones new or old. Missing smart voltage like PPS or QC which means shorter battery life. Your camera and its batteries likely require QC not present on the Type A ports. If you will be charging two phones at once again dig deeper. Not optimized for either long battery life or current phone charging speeds. Definitely not ideal for any generation Galaxy.
This charger does support Programmable Power Supply (PPS) with currents up to 5A supported meaning it should support 45W Super Fast Charging 2.0 when using a single port. Using one or both of the USB-A ports while using a single USB-C port would limit the USB-C port to 25W Super Fast Charging. More notable is that 25W Super Fast Charging is supported on the USB-C1 port even when the charger is fully loaded!

In addition, the USB-A ports are limited to no more than 12W through a single port while they share 15W between both ports meaning in a worst case you get basic 2.5W (500mA) charging from one of the ports if the other port negotiates to max itself out (I purposefully still use 2.5W charging as my overnight default for my phones). This is a bit better setup than those shared configurations which potentially allow for one of the ports to essentially go to zero(!).

Use One Port: 100W Max on USB-C1 or 12W Max on either USB-A
  • 5V 3A
  • 9V 3A
  • 15V 3A
  • 20V 5A
  • (PPS) 3.3-21V/5A, 100W Max
Use multiple Ports: 65W+20W+15W
USB-C1: 65W Max
  • 5V 3A
  • 9V 3A
  • 15V 3A
  • 20V 3.25A
  • (PPS) 3.3-21V/3.25A
USB-C2: 20W Max
  • 5V 3A
  • 9V 2.22A
USBA: 15W Max across both ports with either port limited to 5V 2.4A (12W)

Good luck!
Jon

Thank you for the correction, I'll fix that. Best Buy doesn't publish likely because Geek Squad is stll learning about volts and amps,

But what is available from the A ports? Looks like just dumb 5 volt to me. Too many phones and banks require QC 3 or better to fast charge, 5V-9V with some requiring 12 volt. Galaxy S10+ charges in 200 millvolt steps from 3 volts with the latest QC power supplies. I have power banks that go up to 27 watts on QC.

The good news is that either USB-A can deliver 5V at the maximum 2.4A (12W). The tricky part is that when using both USB-A ports they are limited to sharing 15W total, suggesting that when two devices negotiate charging one could get a measly 500mA (2.5W).

Of course, this is still better than some chargers which, for example, share 18W across three USB-A (meaning one device could get negotiated to ZERO).

This device otherwise lacks support for QC via USB-A. Personally I only have one device that I daily drive which even supports QC.

Good luck!
Jon
