Power consumption of the Clesana C1 with and without Clesana Power Management

Traveling self-sufficiently also means keeping a close eye on your camper’s power usage. The Clesana C1 sealing toilet is ideal for supporting independent travel but requires electricity for the sealing process, it’s important to know how much energy the Clesana C1 uses—and how much difference the Clesana Power Management makes.

Those traveling in their own camper enjoy a sense of freedom and independence. That’s exactly why a self-sufficient and reliable toilet system is so essential. A key factor here: power consumption. Especially in off-grid setups with solar panels or portable power stations, every watt-hour saved counts. Which brings us to the key questions: How much power does the Clesana C1 actually use, and what role does the Clesana Power Management play?

Innovation in Toilet Systems

The Clesana C1 sealing toilet, which operates without water or chemicals, is perfectly suited for this kind of travel. It is based on a process from medical technology that uses thermal pressure sealing. Everything—from waste to hygiene products—is securely and hygienically sealed in a high-barrier foil. This allows for absolutely hygienic and odor-neutral disposal via standard household or residual waste.

Power consumption of the Clesana C1 – without Clesana Power Management

Below is a breakdown of power consumption when the Clesana C1 is connected directly to a 12V battery. These values show that the actual energy consumption per use is low, but the short-term high power demand of 22 A can be a challenge for some self-sufficient systems.

Parameter	Value
Battery nominal voltage	12 V
Input voltage range	11,8 – 15 V
Current draw in standby	0,28 W
Max. current draw (short-term)	22 A
Energy consumption per sealing	0,55 Wh
Energy consumption per cutting	1,7 Wh

The Clesana Power Management

With the optional Clesana Power Management, the Clesana C1 can be installed using a decentralized support battery. This smart add-on module combines the functions of a relay and a DC/DC charger. When the vehicle’s electrical system is active, the Clesana C1 can operate and the support battery can be charged at 2 A via the Clesana Power Management. When the vehicle system is switched off, the Clesana C1 draws no power. Control is managed via a 12 V permanent positive cable.

Major Advantage: Enables greater self-sufficiency! Even if the main vehicle battery fails, the Clesana C1 continues to function.

Overview of technical advantages

Combines relay and isolation switch in one
Operates independently of the camper battery’s BMS
Reliable performance, even with sensitive battery management systems
Easy maintenance via the service hatch
Quick removal – ideal for vehicle change

Power consumption of the Clesana C1 – with Clesana Power Management

When the Clesana C1 is connected to a support battery via the Power Management system, peak power demand is reduced to one-tenth. This protects smaller onboard electrical systems and allows more frequent use even with limited battery capacity.

Parameter	Value
Battery nominal voltage	12 V
Input voltage range	10,5 – 14,8 V
Current draw in standby	3 mA (=0,036 W)
Max. current draw (short-term)	22 A
Energy consumption per sealing	0,55 Wh
Energy consumption per cutting	1,7 Wh

Who benefits from the Clesana Power Management?

Whether you’re a full-time vanlifer, vacation camper, or occasional weekend traveler – the Power Management is worthwhile for anyone who values reliable power supply to their toilet. In emergency situations, such as a failure of the main battery, the benefit is clear: The Clesana C1 sealing toilet can still be used even when the rest of the vehicle has no power.

It’s also a great advantage for those who don’t use their camper for months at a time. A switch allows the toilet to be completely disconnected from the power supply when not in use—eliminating standby power consumption entirely.

Conclusion: More independence, more safety, less power consumption

Using the Clesana C1 in combination with the Power Management offers numerous advantages that are especially crucial for off-grid travel. Power consumption is significantly reduced – particularly in standby mode – and the short-term power demand is minimized, which is a real benefit for those not connected to shore power.

At the same time, operational reliability increases: Even in the event of a main battery failure, the toilet remains functional thanks to the integrated support battery. The system is also easy to install, operates independently of the camper battery’s BMS, and can be quickly removed when switching vehicles making the Clesana Power Management a smart and practical upgrade. Anyone who values true self-sufficiency, comfort and reliability will definitely benefit from the combination of the Clesana C1 and its dedicated Power Management system.

About Clesana

Clesana is an innovative company from Switzerland that is redefining mobile sanitation solutions. With the Clesana C1, the company has developed a sealing toilet that uses thermal pressure sealing to deliver the highest levels of hygiene, comfort, and safety. Excretions, hygiene products and similar materials are securely sealed in a high-barrier foil and can be easily disposed of with regular household waste. This eliminates the need for supply and disposal stations, enabling true independence.

The Clesana system has its origins in the medical field, originally designed to protect Swiss waters from contamination by pharmaceutical residues, hormones, and other chemicals. As a result, the Clesana C1 holds itself to the highest standards of hygiene.

The renowned Fraunhofer Institute has confirmed that Clesana bags perform best by far in terms of odor barrier and leak protection. The high-performance barrier ensures that excretions and other contents are securely enclosed, preventing any contact with the contents for users and all those involved in the disposal process.

The Clesana C1 operates without water, conserving this valuable resource. It also completely avoids the use of harmful chemical additives. A bio-based high-barrier liner made from biomass and recycled materials will soon be available. Additionally, the C1 is manufactured entirely in Switzerland, keeping its carbon footprint to an absolute minimum.
