What exactly does USB 3.0 have to do with charging? Will it not be backwards-compatible with 2.0?

- isarrentheg 17y agoYes, but with 3.0 devices won't the outlet allow more power?
- pronoiac 17y agoEr, yes: 50% more power is provided for unconfigured or suspended devices (150 mA up from 100 mA), and 80% more power is available for configured devices (900 mA up from 500 mA).

- duskwuff 17y agoI suspect that the outlet will give you more power than that anyway - the amperage limits restrict what devices should expect to get, not what hubs may provide them with.
