I was looking for a Li-ion power source adapter and found this in the process.

Looks like it would serve as a UPS for a rPi in many situations.  The
listing isn't big on specs, but they seem to show it will drive well over an
amp in a pass through mode.  They talk about a couple of amps on each of two
ports in power bank mode.

I know this has been kicked around a bit here, but I  don't know if anyone
found an economical solution.  This unit is around $10 and a Lithium battery
will cost around another $4 or $5.  You can either use the standard 18650
type or one of the Lithium polymer flat cells.  Both seem to be available
cheaply with about 3000 mAHr capacity running a typical pi for around 2 hours.
