This version of the S1 Dry Flush Sealing Toilet has no internal battery and runs straight off your rig's power. There's nothing to charge and nothing to remember.
Inside, it's the same S1. Solids and liquids stay separate, and one push of a button heat-seals your solids in a bag. No composting, no layering, no blue juice.
How do you power the S1 without a battery?
All it needs is your rig's 12V system. The S1 comes with its own power cable, so you just wire it into your house (leisure) battery with a 10A fuse and you're ready to go.
The sealer pulls a short burst of current when it seals, so cable size matters. If you need to extend the run, use awg14 or 2mm cable for your run length, and fit the fuse as close to the battery as you can.
The battery-free S1 runs on 12V only. It isn't compatible with 24V systems, and it can't be plugged into a household socket. If you want a toilet you can use away from your rig's power, the battery-powered S1 is the one for you.
Your S1 Dry Flush Sealing Toilet, two high barrier liners, and the power cable for wiring into your 12V system.
Patent-pending, because nobody else has figured this out yet.

Common Questions
Straight answers only.
-
Traditional dry-flush toilets bag every single use — liquid and solid together. You burn through expensive proprietary refills fast, and you're effectively paying to seal urine in plastic. The S1 diverts liquid into a separate 6.5 litre bottle and only seals solids. That's up to 80% less bag use, dramatically lower running costs, and far less plastic waste. It's the first dry-flush toilet with urine diversion built in.
-
Each liner roll gives ~25 uses. For 2 people with regular use, that's roughly every 1–2 weeks. Swap takes under a minute — no tools, no mess. Refills are available on CompoCloset.co.uk
-
The urine bottle holds 6.5 litre. For two people you will empty it every 1-2 days. The LED indicator tells you when.
-
Good news — you don't need to buy the full S1. The S1 Dry Flush Adapter Kit converts your existing Cuddy or Cuddy Lite into a sealing toilet. Plug-and-play, no permanent modifications required.
-
If you run out of bag liners the S1 has a built-in backup mode — it converts to a standard urine-diverting toilet You're never left without a working toilet.
