Modiwell EVO LE-310 Review: A Portable Camping Toilet Worth It?

Not every trip has a toilet on hand. Tent campers have never had one at all, and plenty of van conversions skip it too - either to save the space and cost of plumbing, or because retrofitting a cassette system into an already-finished van isn't simple. A portable camping toilet is the usual fix, and a dry flush model like the Modiwell EVO LE-310 fills that gap without needing any plumbing at all - no water lines, no black tank, no fixed installation, just something you pitch next to the tent or stow in the van when it's not needed and set up in a couple of minutes when it is.

What is a dry flush toilet?

It's a separate category to the camping toilets most people already know. A chemical cassette toilet (the bucket-with-a-seat style camp toilet) needs chemicals to control odour and a dump point to empty into once it's full. A composting toilet separates liquid and solid waste and relies on ventilation and drying time to manage smell, which makes it more of a semi-permanent fixture than something you pack away.

A dry flush toilet skips both of those trade-offs. Each use gets sealed into its own individual bag the moment you're done - no chemicals, no waiting for anything to dry out or compost, and no tank to empty at a dump point. Because every use is sealed on the spot rather than sitting in an open tank, there's no odour build-up between uses the way there can be with a cassette toilet that's been out in the heat for a few days. The trade-off is ongoing cost - you're buying refill bags rather than just rinsing a cassette - and that's worth weighing against how often you'd actually use it.

What it is

The LE-310 is a portable dry flush toilet - no water, no chemicals, no black tank. Each use gets sealed into an individual bag through a heat-sealing mechanism, and the sealed bags go into general waste rather than a dump point. The bags themselves are certified compostable, and Modiwell's own comparison puts disposal on the same level as "handling diapers" rather than anything you need gloves or a hose for. One thing specific to Australian orders: due to local customs rules, the coagulant sachets that ship with US orders are swapped for an equally-rated super-absorbent paper instead - worth knowing so you're not expecting the same packaging shown on their US product photos.

It folds down via collapsible legs for storage - 44.5cm × 40.5cm × 27.5cm folded, opening out to 44.5cm × 40.5cm × 80cm in use - and weighs 7.5kg, so it's genuinely something you can stow in a cupboard rather than a fixture you build around. It's rated to support up to 150kg. For anyone packing a 4WD or a tent where every bit of boot space is already spoken for, that folded footprint and 7.5kg weight matter a lot more than they would in a caravan - it's the difference between finding room for it and leaving it behind in favour of a bulkier chemical toilet.

Where it earns its keep

• Tent camping - no toilet block nearby, no cassette to carry, just something you can set up beside the tent and pack away again. It's also a genuine relief if you don't have a hose or a tank to rinse out afterwards, since a sealed bag just goes into general waste instead.
• Vans and campers with no toilet built in - a proper facility without retrofitting a cassette system or running plumbing into a van that's already finished.
• Remote touring and free camping - anywhere away from public facilities for days at a time, without needing to plan around where the next one is.
• Tight builds where a fixed toilet cubicle doesn't fit - it folds flat and only comes out when needed, rather than taking up permanent floor space.
• Backup for an existing setup - even with a cassette or black tank already on board, handy to have on hand if it's full or a dump point isn't nearby.

How it's powered

The sealing mechanism runs off a built-in 57.5Wh lithium battery - Modiwell rate it at 70 to 100 sealing cycles per full charge, recharging in 2 to 3 hours via a 14V 2A DC charger. For most trips that's plenty of runway between charges.

Worth knowing before you buy: the battery is built into the unit, not removable. One buyer review flagged this directly - they'd have preferred a swappable battery (like the LE-310's main competitor, Laveo, uses) so they could charge it away from the unit itself, or keep the battery out of a below-freezing space while the unit's in storage over winter. If you're storing the toilet somewhere that gets properly cold, or you won't always be near a power source to charge the whole unit, that's a genuine limitation rather than a nitpick.

There's also a documented safety feature worth knowing about upfront: an "Error Code E4" cutout that stops the heat-sealing bar if it detects an obstruction, to prevent injury. It's a sign the sealing mechanism is doing what it should if it ever comes up, not a fault - but it's the kind of thing you don't want to be troubleshooting for the first time mid-trip, so it's worth reading Modiwell's guide on it once before you're relying on the toilet daily.

What buyers say

Feedback on Modiwell's own site is limited (a handful of reviews at time of writing) but specific rather than generic. One buyer, around 183cm and 100kg, said it was "plenty big enough," calling it the "best solution out there for the price" and noting "100 percent better than a cassette and bucket" - with the caveat not to leave used bags sitting in heat for long. Another, building out a Sprinter van, highlighted how straightforward it was to learn and set up, and specifically that it needs no plumbing or black tank at all. A third called it "a completely different tier of portable toilet," praising the folding-leg design as a space-saver and confirming no odour at all once a bag is sealed.

Customer service comes up unprompted in nearly every review - buyers specifically called it "world-class" and said the team was "responsive, friendly, and helpful." Worth knowing if something does go wrong with the unit.

Accessories worth knowing about

Modiwell sells the LE-310 largely on its own, with a handful of accessories separately:

• Refill bags - sold either as bags only (from $27.99, 60 uses) or bags plus coagulant (from $34.99, 60 uses) for solidifying liquid waste. The coagulant version costs more but saves buying it separately if you're using the toilet for solid waste regularly. Worth ordering alongside the toilet itself rather than waiting until you're low - a reorder ships on the same 7-14 business day timeline, so there's no fast way to top up mid-trip if you run out. A simple habit that avoids this: reorder once you're about halfway through a pack, so there's always a buffer in hand for a trip you didn't plan for.
• 12V car kit power supply ($12.99) - a cigarette-lighter adapter for charging the unit directly from a vehicle. Worth having if you're relying on 12V power rather than mains - tent and 4WD setups especially, where there's no 240V socket to plug the standard charger into.
• Carry bag & waterproof cover ($39.99) - built specifically for the LE-310, with double-zipper construction and waterproof fabric, for anyone transporting it rather than leaving it fixed in place.
• Reusable urine tank ($39.99) - diverts liquid waste separately from the sealed bags, which stretches how many uses you get out of a pack of refills.
• Safety rail / stable support ($99.99) - a support frame rated to 136kg with a non-slip handle. This one's aimed more at home, rehab, or accessibility use than camping - worth knowing it exists if the toilet's doing double duty, but not something most campers need.

All of these are listed alongside the Modiwell EVO LE-310 itself once you're on their site.

Should you get one?

If you're tent camping or your van doesn't have a toilet built in, the LE-310's spec sheet backs up what buyers are saying: sturdy, straightforward, and properly odour-free once a bag's sealed. The built-in (non-removable) battery is the one real trade-off against its closest competitor, worth weighing if you store the unit somewhere cold or won't always be near power to charge it. It's currently listed at $729.99 USD (roughly $1,100 AUD, depending on the exchange rate), backed by an 18-month extended warranty and a 30-day return window for quality issues.
