Finding an adapter such as that shouldn't be too much trouble.
As a note, 2000mA = 2 amps. Any adapter that will send through 2 amps
(2000 mA) or greater should work for you. For instance, you could
purchase an adapter that provides 3.5 amps (3500mA) of throughput, and
your device would only use what it needed, though higher throughput
will generally mean a higher price.
Unfortunately, I can't point you to a specific item, because AC-DC
adapters can use several different "plug" tips. However, there are
resources out there to help you figure out which electrical tips
you'll need for your specific devices.
Targus Adapters & "PowerTips"
Targus, Inc. is one of the leading manufacturers of adapter products,
available at many stores across the US, including Office Depot and
Best Buy. If you check out their web site's power accessories
section, you can use their "PowerTip Configurator" (linked near the
top of the page) to see which Targus tips would fit your devices.
Then most any "Universal AC Adapter" listed in that section should
work with your device if you purchase the additional PowerTip(s)
required by your device(s). Just make sure that the particular
adapter you choose can handle greater than 2 amps of power throughput.

Other brands of adapters should also be available at most consumer
electronics stores. In particular, check for universal notebook
computer ac adapters, as they are designed for power-hungry computers
that necessitate the 2+ amps your devices need.
Please let me know if I can be of further assistance.
