When you search for caravan accessories, you’ll quickly come across terms like “heavy duty”, “extreme protection” and “suitable for any vehicle”. Such descriptions don’t always tell you enough about practical usability. For example, a tape might look wide enough, but not be suitable for a wet surface. An inverter might show a high peak power, while the continuous power is much lower.
With this guide, you can assess maintenance, moisture, cooling and power products based on verifiable features. This way, you choose accessories that suit your caravan, campervan, boat or vehicle.
A 12V inverter often lists a high peak power. This is the power that can be available briefly, for example when starting a motor. For long-term use, the nominal or continuous power is more important.
An inverter with 2,000 watts peak power and 1,000 watts continuous power is therefore not intended for connecting a 2,000 watt load for extended periods. Also check whether your household appliances are suitable for use via an inverter.
A roll of waterproof butyl tape won’t fix poor preparation. Dust, grease, old sealant and moisture can reduce adhesion. With many butyl tapes, the surface must be completely clean and dry. The tape also needs to be left undisturbed for a certain time after application and protected from rain.
Therefore, use leak-sealing tape mainly as a targeted repair or seal. For structural damage to a roof, wall or window, the construction itself needs to be inspected.
A large portable cool box isn’t automatically practical in a caravan. Pay attention to the available space, the weight, the power connection and the type of cooling. A compressor cool box works differently from a simple thermal cool box and may be suitable for long-term cooling, but it does require a suitable 12V connection and enough ventilation space.
For small seams and localised leaks, 50 mm wide tape can be handy. For a larger overlap, for example on a roof edge or awning, 100 mm or 150 mm width offers more coverage. In addition to the width, also check the length and thickness.
The TAPEBEAR variants in this selection use butyl rubber with an aluminium foil and polyester or non-woven backing layer, according to the product information. The stated temperature range of some variants runs from -40 °C to 80 °C. That is a product specification, not a guarantee that every surface or repair is suitable under all conditions.
Also pay attention to the surface: PVC, EPDM, glass, metal, wood and plastic can require different preparation. According to the product information, the tape is not intended as electrical insulation.
A power supply for a caravan must match the battery and the connected devices. Check:
Use sufficiently thick cables and do not place the inverter in a damp location. Never connect it directly to the mains electricity supply.
A caravan moisture absorber works without electricity and can help to capture moisture in an enclosed space. Place the unit securely and check the reservoir regularly. The liquid that forms can cause stains and must not come into contact with materials such as leather, wood, natural stone or metal.
A moisture absorber does not replace ventilation, leak checking or drying after rain. If condensation or a musty smell keeps returning, it’s wise to find the cause first.
Why this fits the profile: The 50 mm width is manageable for small seals around windows, awnings, pipes and localised leaks.
The product information clearly states that the surface must be clean and dry and that the tape is not intended for electrical insulation.
50 mm wide, 5 metres long and made with butyl rubber, aluminium foil and non-woven reinforcement.
Why this fits the profile: The extra-wide roll is aimed at larger sealing surfaces, such as caravan roofs, windows, gutters and awnings.
The 150 mm width reduces the chance that you’ll need to place several narrow strips side by side for a wide gap.
Aluminium foil, polyester and butyl rubber; according to the product information suitable for PVC, EPDM, glass, wood and metal, among others.
Why this fits the profile: This inverter is intended for users who want to run multiple devices or equipment with a higher starting load from a 12V battery.
The specifications distinguish 4,000 watts peak power from 2,000 watts nominal power, so you can better match the load.
12V DC to 220V AC, dual digital displays, two temperature-controlled fans and multiple protection features.
Why this fits the profile: This device works without electricity and is therefore suitable for a caravan that is stored unused or closed up.
The operation and maintenance are straightforward: place the tablet, check the reservoir and replace the refill when it is saturated.
Reusable holder, 450 g moisture-absorbing tablet and application in caravans, boats, garages and cupboards, among others.
For food and drink, alongside a fixed caravan fridge, you could also consider a portable compressor cool box. According to the product name, the BINGI cool box has a capacity of 22 litres and works on 12/24V DC. The AAOBOSI models offer larger capacities: 45 litres or 110 litres, with the 110-litre version listing two zones.
Before buying, compare the dimensions with your storage space. Also check the energy consumption, cable length and the ability to place the unit stably. For a short picnic, a compact cool box is often sufficient; for longer trips, a larger compressor model may be more practical.
Other useful camping accessories and campervan accessories include spare cables, cleaning products, connection adapters, ventilation grilles and a simple caravan repair kit. When choosing, don’t just look at the price, but also at the connection type, size and material compatibility.
We have compiled a full, up-to-date list of products that fully meet these strict selection criteria and current European safety regulations.
Start with products for the most likely problems: a suitable repair tape, a moisture absorber, appropriate power cables and a cooling solution. Also check the dimensions and connections before you take anything with you.
The lifespan depends on the surface, temperature, UV exposure, movement and preparation. Store an unopened roll in a cool, dry place. An applied strip should be checked regularly, especially after frost, heavy rain or moving the caravan.
The cost mainly depends on the power of the connected device, the duration of use and the battery capacity. A device with a higher wattage will drain the battery more quickly. Therefore, look at the continuous power and the battery capacity before choosing an inverter.
