Water and battery, by the numbers
Two numbers decide how a portable bidet actually performs day to day: how much water it holds per fill, and how it's powered. Here they are without the marketing language — 250 mL and 450 mAh, and what each one means in practice.
Reservoir: what one fill actually covers
The built-in reservoir holds 250 mL. At a steady 500 mL/min, that's roughly 30 seconds of continuous spray — a full clean for most people without a mid-use refill. It's a starting point, not a hard ceiling: the included universal bottle adapter twists onto any standard water bottle, so more water is always one twist away, whether that's a hotel-room bottle or a tap.
This is worth knowing precisely rather than approximately, because "one fill" means something different depending on the flow rate behind it. A slower manual squeeze bottle needs a larger reservoir to deliver the same total water; a steady electric pump can do more with less, which is part of why the reservoir doesn't need to be large to be sufficient.
Battery: what the number means and what it doesn't
The battery is 450 mAh, rechargeable over USB-C. That figure describes the battery's capacity, not a fixed number of uses — actual runtime depends on how long the pump runs each time you use it, the same way a phone's battery percentage doesn't translate to an exact number of hours regardless of what you're doing with it.
What that capacity is built for is multiple uses between charges under normal use, not a single trip to the outlet after every clean. And because it charges over standard USB-C, topping it up doesn't require a specific wall adapter — a phone charger, a laptop port, or a power bank all work.
The numbers, in one place
| Reservoir | 250 mL |
|---|---|
| Flow rate | 500 mL/min |
| Battery | 450 mAh |
| Charging | USB-C |
Is 250 mL enough for one use?
Yes, for most people. The pump runs at a steady 500 mL/min, so a full reservoir is about 30 seconds of continuous spray — enough for a complete clean without needing to refill mid-use. If you want more, the universal bottle adapter lets you twist onto any standard bottle for as much water as you need.
How many uses does one battery charge last?
The battery is 450 mAh and recharges over USB-C, the same cable most phones use. Runtime depends on how long you spray each time, so rather than quote a fixed number of uses (which varies person to person), the honest answer is: it's built for multiple uses between charges, not a single one.
What happens if the battery dies mid-trip?
It recharges from any USB-C source — a phone charger, a laptop port, a portable power bank, or a car USB socket. There's no proprietary cable and no dedicated wall adapter to lose, which matters more on the road than it does at home: the cable already charging your phone will charge this too. If you're somewhere without power at all, a small USB power bank covers it, since the battery is a fraction of the size of the one in a phone and takes correspondingly less to top up.
