I think a matrix, just by itself, will just cause confusion in less effort. It certainly visually shrinks the options but it is still a confusing long list and still needs a geeky level of knowledge. I think we should remove the geeky aspect.
Here is my matrix
This matrix I produced is focused on what matters to me, which is energy density and speed.
I think what most will need is not a matrix but they begin with a few questions of what matters to them and then it runs a stacking filter and narrows down to one or a couple of likely products.
These questions should be:
- select from common devices (iphones, Samsung, etc) and if your phone now shown then enter the mAh (you can find off the 'net fairly easily) and if its QC etc.
- how many recharges you want.
- possibly if you care about say speed or cost
- it then shows a screen with the selectoins you made at the top of the screen which you can change/remove to widen/change your selections.
The filters in some cases should be additive so you add a phone and a tablet or a phone and say BT headphones.
Then really, the 80/20 rule will kick, popular phones and they just know what they want to accomplish, would serve most folks. Geeks can just not narrow the search done by Anker and peruse all products and make their own calculations.
Doing this for portable chargers, and chargers, would then work in the additive, so e.g. when you're saying 5 devices to charge it drives to more sockets portable chargers and more sockets chargers.
