This looks like the sort of thing you put next to the bed in which case you've got 8 hours to charge and fast charging therefore has no benefit.
If it's a desk product then maybe it has a use if you really don't want to use any of the three products for 45 minutes during the day which I find highly unlikely, but the need to charge during the day is rarely necessary nowadays and it's exceedingly rare you have all three products that need charging at the same time.
Plus, you will still need other chargers if you travel or are you going to pack that to go to a hotel?
A three socket extension lead and the chargers we have already will suffice and $150 can be better spent elsewhere.
Very small market for this: it's not even something you are going to want to show off.
