USB Hub Charging

I just bought a new USB 2.0 4-port hub to replace my old/slow USB 1.1 4-port hub...

"Plugable USB 2.0 4 Port Hub and BC 1.1 Fast Charger with 2.5 Amp Power Adapter"
Amazon.com: Plugable USB 2.0 4 Port Hub and BC 1.1 Fast Charger with 2.5 Amp Power Adapter: Computers & Accessories

It has BC 1.1 (battery charging) capability, and can charge hardware that is compatible. It is difficult, it not impossible, to find a list of compatible hardware, but apparently the Playbook is.

Plugable| Plugable USB2-HUB4BC 4 Port USB 2.0 Hub with BC 1.1 Fast Charging
"Charges BC 1.1 compliant devices at up to 3x normal rate (1.5A) on any one port"

I have only used it once so far, but the battery went from 58% to 100% in less than 37 minutes (I wasn't watching closely enough, and just looked up and it was done!)

I have had the Playbook (64GB) about a month. I also have a 10" android tablet (Motorolla Xoom), but really like the 7" form factor.

Additional accessories that I am very happy with include:

Samsonite Classic Netbook Shuttle - holds every thing quite handily; playbook, charger, earphones, etc.!

Trexta Marquis Case - very nice/functional leather case

The forums here have been very helpful to me and I hope someone finds the information above helpful :)

Charging that much in that little time would require a charging rate of more than 12.25W, which isn't likely possible. Was it super hot after that?

I don't know what happened to get you those results, but I'm afraid nobody should take them as indicative of what that charger can actually do.

I'm not too sure how accurate my battery indicator is....it did go to 100% fast...and has taken a longer time than usual to drop below 100% after that charge. I was wondering if it had anything to do with the latest update?

Hub nor Playbook felt 'hot' during charging.

As far as I see on the spec sheets, this 'Pluggable' adapter is a 1.5 Amps charger, half the PB fast charger. Its charge time should be something like twice longer than with the fast charger -and not longer than with the normal one. Visibly, Pluggable also proposes 3-Amps chargers, which should get as fast as the PB original fast charger.
