Just curious if there's a portable power pack that'll work on phones and android tablets alike?
Yes. It depends on your devices, on what is available.
Here is a power pack that fits any device that uses a micro USB and or a USBA port.
Portable power pack
If you list your devices i am sure we can find some for you.
Oh, no, Im just curious, I dont have a tablet at the moment, I do have a HTC Thunderbolt though-still going strong after 19 months woo! I just wasnt sure if power packs for phones worked differently than one for a tablet would is all.
What you would need to do is just make sure the out put of the power pack is strong enough to charge the device. Most power packs are but you never know.
You should be able to use a power pack or external charging pack with all your mobile devices. As long as your power pack is providing enough power to trip the charging circuit, the amount the device will use is whatever the power pack has specified. You probably might want to do some research because some are made for smaller devices, and some can even charge a laptop.
I have a Ravpower 10000mah power bank and it has been able to charge all my smaller devices with no issues. It has 2 ports, one port output is 5v1a and the other one is 5v2a. I have a iphone 4s, galaxy 3, kindle fire and kindle touch and it has been able to charge all with no issues.
There are way too many options now, your best bet is to wait for sale and get that.
Zagg makes several different models that will do that too.
This product is pretty interesting because you can have unlimited charging by adding more batteries. It is called Exogear Exovolt Plus Stackable Battery Pack. I found it from below link but you might also find it by google it.

NewTrent.com makes external battery packs compatible with both tablets and smartphones at the same time, I believe.
Their easypak has a 2.1A port for tablets and 2 1A ports for smartphones, so you can charge 3 devices at the same time.
There are a lot of choices, if charge the phone, 5000~8000 mAh is good enough, if charge tablet, I would sugget bigger capacity, such as 12000~20000 mAh.
