It doesn't supply 9v, it provided 5, 12, and 19v.

whoops.  right.  so, it will run the R-44 on 12v and fade the rest as heat?

i'm guessing the 14000mah number is based on 5v, right?

also, who knew these could jump start a car?   ???

got it in.  need to go to ratshack and find a tip that fits.  will update.

Update:  it takes an adaptaplug tip "N" as the output.  powers up my R-44 perfectly.  running a duration test now.

How'd things turn out? Runtime? Any chance of pics with the battery next to the r44?

14000mah is probably based on the 3.2v-3.4v internal cell voltage, which is the typical marketing speak these days

so this battery is probably about 44.8 - 47.6 Whr

It has a circuit in it to handle HIGH Amp's TEMPORARILY to start a car - a normal ~12v Lithium battery would probably melt/explode or shut off if you tried to start a car with it

forgot to update.  it ran the R-44 for a few hours.  but not nearly as long as a 5400mah dvd battery.  overall bust i think.
