Help, not sure what to buy?

First I am curious what the difference between the POowerport speed charger and Powerport + charger. They are the same cost but one has blue and one is green?

Also what’s the difference between these 3. They all look similar?

The difference between the two is that for the Powerport Speed 5 charger it has 5 ports, & 2 out of the 5 ports have Quick Charge 3.0 capability. For the Powerport+ 6 it has 6 ports & only has 1 port out of 6 that has Quick Charge 3.0 capability.

As for the difference between those 3 Powercore 10000 power banks: the Powercore Speed 10000 QC is the 3rd & latest model that utilizes quick charge 3.0 as well as technology to “ensure it stays cool when charging and recharging.”

The PowerCore 10000 with Quick Charge 3.0 was the 2nd model that updated the look & made it slimmer than the previous 1st model to be about the size of a credit card.

And the PowerCore+10050 with Quick Charge 3.0 was the first original model to incorporate quick charge 3.0 technology. Its slightly bigger & bulkier compared to the newer models.
