Choosing a portable toilet for camping and hiking forces you to balance two things: how long you'll be away from a restroom and how much gear you're willing to haul. Uimoso's two pump-flush toilets are designed for the same outdoor situations, but they make that trade-off differently. The larger model is priced at $89.99 and built for bigger duty. The smaller model is $72.99 and much easier to move. So which one belongs in your car or backpack?
Quick verdict: Choose the larger model if you're car camping, base camping, or sharing one toilet among several people. It holds roughly 200 flushes per fill and can support a static load of 396 lbs. Choose the smaller model if you want a lighter, more packable toilet for hiking, shorter trips, or smaller vehicles. It weighs 11.0 lbs, about a third less than the larger model, and costs $17.00 less.
Both share the same PP/ABS/HDPE construction and manual-pump flushing, so your choice really comes down to how much capacity you need versus how much weight you want to carry.
Here's the full comparison:
| Feature | Uimoso 7.9-Gallon Flush | Uimoso 5.3-Gallon Flush |
|---|---|---|
| Price | USD 89.99 | USD 72.99 |
| Flush tank | 7.9 gallons | 5.3 gallons |
| Max flushes | Approx. 200 times | Approx. 120 times |
| Load capacity | 396 lbs / 180 kg (static) | 330 lbs / 150 kg |
| Weight | 16.5 lbs / 7.5 kg | 11.0 lbs / 5.0 kg |
| Dimensions | 20.9 x 15.7 x 17.9 in | 17.1 x 14.0 x 16.9 in |
| Material | PP/ABS/HDPE | PP/ABS/HDPE |
Where each product wins
- The larger model wins on capacity and strength. With about 200 flushes per fill and a 396-lb static load rating, it's better suited for group campsites or a long weekend with multiple people.
- The smaller model wins on portability and weight. At 11.0 lbs, it's easier to lift into a car trunk, carry a short distance, and pack into a tight space.
The right pick depends on where the toilet will be set up and how many people will use it.
Uimoso Portable Outdoor Toilet with 7.9 Gallon Flush for Camping and Hiking
This is the model to reach for when you're not counting ounces. The larger flush tank, paired with a 9-gallon waste tank, means you'll need to empty it less often. The manual pump pressurizes the water for a flush that helps keep waste contained and odors down. With a 396-lb static load limit, it can handle a broader range of users. The main downside is physical size and weight: 16.5 lbs and a footprint of about 21 x 16 x 18 inches. That's fine for a base camp setup, but not something you want to carry on a long hike.
Uimoso Portable Outdoor Toilet with 5.3 Gallon Flush for Camping and Hiking
If you're looking for the easier-to-manage option, this model shaves off 5.5 lbs and a few inches in each direction. It still uses the same manual pump and leak-resistant design, and the 120 flushes per fill cover a weekend for one or two people. The static load limit of 330 lbs is lower than the larger model, and the waste tank is a more modest 3 gallons, so you'll need to empty it more often during extended trips. It's the lighter of the two, a sensible pick for hikers and solo campers who want a functional toilet without the bulk.
Final choice by use case
For group camping, long weekends, or anyone who prefers fewer empties and more flush power, the larger Uimoso is the clear pick. For hiking, kayak camping, or a one-person setup where every pound matters, the smaller model makes sense when portability matters more than capacity.
