lopek77 did say that the eBay version had a newer emitter. Now, I don't know how much of an improvement that makes, but if it's more efficient that could make having a smaller power pack OK. I'd need to have both to compare to make a proper decision there, and I don't have that eBay version.

It's possible, but won't be easy.
USB (and mini-USB) is 5 volts, where the chargers for these are 8.4 volts (two Li-ion batteries in series are to be charged with a maximum of 8.4 volts.) You'd need to boost the voltage somehow.
