Hi @lily-da-vine - mine has been sitting on top of my ancient old motorhome providing energy for laptops and lights (LED of course, although there is one 20W neon in the mix as well, less frequently used) since about mid 2015.

I'll never be a griddy again - I'll rather go candles and a pedal gennie if ever need be. And my water comes from Above as well...

Enjoy your direct link to universal energy - much more efficient, reliable and pleasing than having to pay for dependance!
