Like I said, Coleman probably doesn't actually manufacture any of them. They just rebrand the ones made by someone else. They most likely only sell them to resellers like the FLAPS, Wal-Mart, Harbor Freight, etc. The Coleman PowerMate website only shows their generators and such, no battery stuff. Harbor Freight has several listed. A couple are Coleman. They all look the same. I don't see any with the built in 110volt inverter. http://www.harborfreight.com/cpi/ctaf/Category.taf?CategoryID=444 They have a small one with a 10Ah battery and no compressor for $29.99 It's Coleman PowerMate branded They have the compressor one with a 17.5Ah battery for $49.99 Chicago Tools branded They have a "big honkin" non-compressor one with a 24Ah battery for $59.99 No brand listed, probably Chicago Tools They have a "waterproof" booster for $69.99 - no Ah listed for the battery but it's small. It's Coleman PowerMate branded (PMJ8660) And they have a really small 10Ah Coleman for $39.99 but it's in a "sleek black case" so they can charge more even though it's "smaller" than the others <grin>. Personally, if I ever get the Rivi running, I'll add an Optima deep cycle battery as a secondary and buy separate inverter/compressor/etc. The Optima can be used for jumps if ever needed and used to run accessories so jumps WON'T ever be needed. I'll probably cut the regular "ligter plug" type 12V plugs off any of my stuff that uses it and install locking style connectors for better contact for use in the bus. Push and twist, no jiggling loose while driving. I hate the "lighter plug" type, always seem to end up with at least one that never makes good contact. I'll make a couple of adapters in case someone else needs to plug in.
