Carl...my 10-14-100 Batterygeek is similar in Watt Hours to this unit...I get 14hrs with one pair of mic's on Phantom and Line in from V2 on a second pair from it...but it's no longer made...
Yeah, this looks like a pretty good replacement for the battery geeks. Love my 10-14-115 and sad to see it's no longer available. 98 Wh is going to last forever and I like the fixed 12v (versus selectable) plus USB options.
The only thing that bothers me about the design of this battery is the on-off switch and its side location. At 8.5" long, it might be hard to run this battery upright in some gear bags and I prefer to have any switches facing up.
