At present my backup power is an Npower 400w power pack.

I love it - when the power goes out it kicks on and lights a 3 bulb tree lamp.  One bulb lights the trailer and a second aimed out a window provides a yard light.

It works easily for 2 days but the drawback is it takes hours to recharge so my genny isn't right for recharging it - after the power goes back on it takes 8-12 hours for the grid to recharge it.

What I have envisioned for its replacement is a power unit that looks like a piece of furniture, a cabinet with a table lamp fixed to the top.

Inside it are a small bank of AGMs to power the lamp, a charger (genny powered), an inverter for AC plugins, and a charger for solar panel hookup.

It would have to be vented for inverter/charger cooling but with AGms it shouldn't pose an explosion hazard.

I was once pretty hip to this stuff but in my dotage I've forgotten more than I remember.

Any advice on building it massively appreciated (so I don't blow myself up).

No one ever accused me of being a genius but I think it's a nifty idea, ay?

Thanks for not laughing.
