It would have to be a dildo, I think. They're not my favourite, but not EVER going to a store again means not relying on batteries (even rechargeable ones eventually die) and not relying on machinery to not fail.

Even something like the solar-powered bullet could break and leave you with something pretty useless.

Wind-up toys can break, too.

Dildos alone don't really do anything for me, so in this situation I think I'd just lose.

Mozzie, is that you?

That said, hm. I already have a Pure Wand, or that'd be my choice.

Hmmm hmmm, I agree, though I just cling to my vibrations too much...

And very much thinking every day (oh yeppp) which would be the most longlasting vibe ever...

Already having solar panels to have juice, still planning to have more, and still hooked up to the grid, so I very much wonder how much the different buzzers would drain the batteries (aka what gives the electricity for yer home - living in the blissfully useful mobile conditions of a fine luxurious RV to get the hell out of anywhere in case W/we couldn't make it to O/our final destination in time, away from everything other than a nearby teenytiny town) - so far W/we still plan to get more panels and batteries, rechargeables wouldn't be a big problem I guess, but what about the ones with a power cord, like massagers for example, would be funny to enjoy my time for an hour or two, then oops, my Master can't use a friggin casual light in the middle of the Night...

Also considering dildos where you have a good enough material to lead the vibrations through the body of it, with a powerful enough bullet slipped in, wonder if glass toys are really as wonderful as people rave about them in this manner, and if simple silicone dildos would work too...

I'm planning to try glass in the near future. If they're as awesome as people say, that might be it for me. Till then I'd have to say my non-mechanical go-to toy is my Tantus Acute.

LOVE YOU TOO MY ONLYMASTER!!!!!!!!!!!! ! NYUUUUUUUUUUUUUUUUUUUU UUUU!!!!!!!!!!!!!!!!!! !!!!!!!!!! ~squeeeeeeeeeeeeeeeeee eezes Him!!!!!!!!!!

Wahl deluxe want, plugs in. No batteries required.

If there's no chance to get lube or batteries or anything like that, I'd go with the Silk Medium. It's not my favorite toy, but it's a good one and about the only dildo I can use without lube if I have to (aside from the Bent Graduate, which I actually like more but it requires more careful storage, and I like being able to thrust quickly if I feel like it). Plus it'll never break like a vibe might.
