Ben Thanks for the tip: the PowerAdd was removed from Amazon when I was first looking around, but seems to have reappeared at a reasonable price, so I bought it, as it was a sure thing to fit snugly in the carry handle slot (as demonstrated. i made some mock-ups of other power banks, but none of them would be so integrated. I’ve found that the knobbly finish on the amp makes mincemeat of the (rather pretty) battery case. Ho-hum!

Cameron I guess you’re looking at plugging in via the AC feature of these units? It seems a bit inefficient to me to convert from DC (power pack battery) to AC (power pack output) then back to DC (through the amp power lead transformer); I’d want to squeeze the maximum time I could out of the battery! I was thinking more of those power packs that have the 19v DC o/p feature, but I’m a bit concerned that they only have about a 4 or 5 amp load capacity before shut-off features kick in. I don’t know what the peak wattage of the BG-75 is, but 95w would shut down the power (5A max assumed).

The PowerAdd Pilot pro2 recommended by PJB is now becoming difficult to get hold of, and the pro3 does not have the 19v functionality. Has anyone tried other suitable power sources recently?
