For those of you who make multiple/extended dives, where there are no AC outlets around ... what are your solutions to recharging the battery? Swapping battery is out of the question, since it is sealed.

This is what I'm thinking, but wondering if there are better alternatives.

Amazon.com: Rosewill Plasma Black 18000mAh Universal AC Outlet Portable Power Bank for Laptop/Smartphone/iOS/Android/PSP (PB-U1-18000-BK): Computers & Accessories
 
Something like that could work, a self contained battery plus inverter to generate portable AC. However, the back of my Photo 800 says 12 Volts by the charging port. I wonder if it would be possible to just use a simple 12V battery as a source with a pair of mini banana jacks.

Apparently Light & Motion does not recommend supplying the light with unmanaged power. The AC adapter contains the necessary smarts to regulate the charge that won't damage the cells. Bugger!

The only place I ran into problems was in the Philippines when a number of our dives exceeded 2 hours. I kept the light off until it was actually needed (except on night dives when they were on all the time). We did two dives per trip and there was time between boat trips to fully charge the lights (thankfully)
 
I hear you Bill. I generally get 2, maybe 3, dives out of the light with good power management. Boat dives are usually not a concern due to available AC outlets. It's the shore dives that get you.

Funny you responded here, as my concern is for Casino Point (Santa Catalina, CA), as place you know very well! :D
Do you know of any AC outlets accessible near the stairs? I'll be there this weekend shore diving.

Hasn't been a concern for me in the past, since my old light uses replaceable batteries.
