What’s in the box
Mini combines the pump, water sensor, battery and solar panel in one unit.
Setup & product manual
Position Mini at the collection point, secure it as instructed and route the discharge hose safely outside the boat. Check the charge, hose and sensor before leaving it in use.

RainTaker is to use
A short lake demonstration from Joe, with Mini on the floor of an inflatable tender and its discharge hose routed over the side.

Dinghies &
inflatables
Less rainwater waiting in the boat you use every day. Mini senses collected water and pumps it away between trips.

Rigid inflatables
& tenders
Independent power for a small boat. Mini uses its own battery, so you can leave your house bank switched off.

Small boats
Your next trip starts with a dry boat. A compact, portable system for the small boat you rely on, with no connection to its electrical system.
Check the fit for your boatA flooded boat
costs more than
a lost day
Rainwater adds weight. Left to collect, it can swamp a small boat. Recovering it, replacing damaged gear and losing access to your tender can turn a simple trip into an expensive problem.
- Recovery and repair costs.
- Damaged gear and equipment.
- A boat you can’t use when you need it.
Mini gives collected water a way out automatically, using its own power supply.

Rain in
Water out
Set Mini at the collection point. Route the hose. When water reaches the sensor, the pump gets to work.
- 01Collected water is detected.
The sensor responds to water at the unit.
- 02The pump sends it overboard.
Stored battery power drives water through the hose.
- 03Ready for the next cycle.
Low charge? The controller can pause and retry while water is still detected. Keep charge, placement and hose routing checked.

Everything
RainTaker does
Choose Mini 
Independent battery power
An onboard battery powers the pump. No connection to your house battery is needed.
Built-in solar charging
The built-in solar panel replenishes the battery, ready for the next cycle.
AC wall charging
Wall charging gives you another way to prepare Mini before putting it in place.
Saltwater capability
A compact, portable system for dinghies and small open boats, including coastal tenders.
Built & tested in the USA
Handbuilt and checked in RainTaker’s testing facility, with two years of warranty coverage.
Solar by day
Ready after dark
Choose Mini The panel replenishes the battery in daylight. Stored energy powers the pump when water arrives, including after the sun has gone down.
01Solar panel
Sunlight replenishes the onboard battery.
02Onboard battery
Stored energy stays ready after dark.
03Water out
When water arrives, the battery powers the pump.
Continuous runtime with no sun
Approximate continuous pumping from a full charge. Automatic on/off cycles can continue as stored energy allows.
Nominal pumping capacity
A marine pump to move collected water out of your boat.
Pumps Pauses
Retries
When charge is low, Mini can pause and retry while water is still detected, including after dark. Low-voltage protection preserves the battery; daylight charging can restart pumping when enough power returns.
Solar or wall power
Two ways to recharge
Let the built-in panel top up the battery in daylight, or use compatible AC wall charging before setting Mini out.
Mini pumping test
An extended indoor demonstration of Mini pumping on its onboard battery, with no sunlight during the test.
Filmed with a fully charged system. Results reflect the conditions shown; charge level, hose routing and discharge height affect performance.
Keep the cover
from becoming
a collection point
A cover keeps rain out of the boat. Mini can give pooled water on a suitable cover a way out, too.
Check cover support, safe placement and hose routing against the Mini setup instructions.

Your experience helps someone choose.
Mini is designed for dinghies, RIBs and small open boats. Boat length alone does not decide the fit. Check the available space, collection point, discharge height, hose route and expected water volume against the setup instructions.
Yes. Mini is saltwater capable. Follow the product manual for setup, cleaning and care in marine environments.
No. Mini powers its pump from its own onboard battery. It does not need to be wired into your boat’s house battery. You still need to check its charge and maintain your boat’s normal bilge equipment.
Yes. The pump uses energy stored in its onboard battery, so it does not need direct sunlight while pumping. Available reserve depends on starting charge, water volume and the discharge setup. The solar panel replenishes the battery in daylight, and compatible AC wall charging offers another way to recharge.
Around 25–30 minutes of continuous pumping from a full charge, without sunlight. This is pumping time, not the length of time the system can remain in place. In normal use, the sensor runs the pump when water is present; charge, water volume and hose setup affect available operation.
When battery voltage falls, the controller can pause the pump and retry while water is still detected. These shorter cycles can continue after dark using the remaining stored energy. Available pumping depends on the charge remaining in the battery.
Low-voltage protection stops the pump before the battery is fully discharged. When daylight provides enough solar charge and water is still detected, the system can resume pumping automatically. Restart timing depends on the light available.
Yes. Mini has a buoyant body and can float if the water level rises around it, including while waiting for enough charge to resume. Follow the setup guide for placement, securing and hose routing. Floating is a product characteristic, not a guarantee against flooding or sinking.
The controller only starts a pumping cycle when there is enough power to move water. If voltage drops below its operating threshold, it pauses rather than continuing to run with too little power. Actual flow still depends on the hose route and discharge height.
A capacitive solid-state sensor detects collected water and activates the pump. It uses no mechanical float switch. Keep the sensor and intake clean, and follow the setup and testing instructions; automatic sensing still needs routine inspection.
Mini uses a NiMH onboard battery to store energy for pumping between charges. Follow the manual for charging, storage and battery care.
A proprietary solar charge controller manages charging, and fused marine pump circuitry provides electrical protection. Follow the manual for charging, setup and maintenance.
Yes, on a suitable supported cover. Place and secure the system at the collection point, with enough support for its weight and a safe discharge route. Follow the setup instructions for placement.
Mini brings together the pump, water sensor, battery and solar panel in one unit. Use the setup-guide link above for charging, positioning, hose routing and regular checks.
Treat Mini as supplemental water-removal equipment. It does not replace the boat’s primary bilge system, maintenance, regular checks or emergency response. Heavy water ingress can exceed any pump’s capacity. Choose and use the system within its approved limits.
