miniFumpa Manual

USB Type-C Version WDCDMV20

Please read and comply with these instructions prior to using your miniFumpa


Intended Use

miniFumpa is intended for use as a portable air compressor for pumping bicycle tyres up to 120psi.

Protect the unit from rain. Do not store outside.

Using a Fumpa Pumps needle valve (sold separately), miniFumpa can be used to inflate sporting equipment such as footballs, netballs and basketballs.

miniFumpa is not to be used to inflate large volume objects such as swimming pools, boats, beach balls and large inflatable toys.

The manufacturer is not responsible for damage due to incorrect operation.


Environmental Protection

miniFumpa contains a lithium battery. Please dispose of miniFumpa correctly.

Charging miniFumpa

Charge miniFumpa by connecting the supplied USB Type C cable to the USB Charge Port (see below). Connect the other end of the USB cable to a PC or USB wall charger (not supplied). The START/STOP button will glow red, indicating that miniFumpa's battery is charging. The START/STOP button will cease glowing when miniFumpa is fully charged. Using a 5V, 2Amp supply, miniFumpa should be recharged in 1 hour.




  • Never leave your pump charging unattended!
  • Do not operate the unit while it is connected to a charger. Doing so can damage the battery! Always disconnect the USB charge cable before use.
  • Counterfeit wall chargers pose a fire risk and can damage your pump!
  • Only charge your pump using wall chargers purchased from reputable consumer electronics stores!
  • Ensure your charger is marked with at least one of these symbols:



Turning on the pump and checking battery charge

Press the ON/OFF button until motor starts to start pumping, then release. Press the button again to turn the pump off. Alternatively, the pump will automatically turn itself off after 50 seconds. Below shows approximate pump-up times of different sized road bike tyres when pumping from flat. After pumping up a tyre, rest the pump for 5-10 minutes. The pump will become warm after use. The pump is not intended to be used to continually pump up tyres.

When the motor is running, you may notice the ON/OFF button flashing. If the button glows red continuously, then the pump is fully charged. If the button flashes slowly, then the pump is between 40-95% charged, and the user should have enough charge to pump up up at least one tyre. If the button flashes fast, then miniFumpa requires charging.

The battery charge can also be checked without turning the pump motor on. By pressing and releasing the ON/OFF button until just before the motor starts, the button will either not flash, flash slowly or flash fast, thereby indicating the battery charge. You can press the button again to turn this feature off, or it will turn itself off after 50 seconds. This feature allows the use to check the battery charge without having to turn on the pump's motor.


Approximate tyre pressures achieved by miniFumpa after 50 seconds runtime (from 0psi)

700x23c tyre - 95-105psi

700x25c tyre - 90-100psi

700x28c tyre - 80-90psi


Changing the nozzle to accept Presta Valves

miniFumpa has been designed to accept both Presta and Schrader Valves:



When you receive your miniFumpa the nozzle will be set up to accept Schrader valves. To accept Presta valves, unscrew the cap, remove the brass insert, flip the seal around and screw the cap back onto the nozzle:


Place the brass insert into the small zip lock bag when not in use, and keep in your carry bag:



Inflating a tyre

Connect miniFumpa to a tyre by pushing miniFumpa's nozzle onto the tyre's valve.

  • Initially, the user may find that the seal inside miniFumpa's nozzle feels tight around the valve. Over time, the seal will soften.
  • Push the nozzle onto the valve nice and hard. Over time, this process will become easier.

Once connected to the tyre, inflate the tyre by pressing and holding miniFumpa's push button until the motor starts. Once inflation starts the button can be released.

Below shows a video of miniFumpa inflating a mountain bike tyre with Schrader valve. We recommend pumping your tyre by locating the tyre's valve near the top of the tyre and standing over the tyre as shown in the video. This method also works best for tubeless tyres as their is less chance in sealant getting into the pump.

In the video you will notice the push button is flashing fast. This suggests that this pump's battery charge is low and requires charging.

The maximum pressure of miniFumpa is approximately 120psi (830kPa or 8.3Bar). However, there is no auto-off feature once this pressure is reach. Higher pressures may be achievable.

minifumpa automatically turns off after 50 seconds. Alternative, miniFumpa can be turned off by pressing the button.

miniFumpa can be disconnected from the tyre’s valve by firmly pulling the nozzle away from the valve.

During use miniFumpa will become warm to touch. This is normal.



miniFumpa is powered via a rechargeable lithium battery. miniFumpa includes battery protection circuitry to ensure safe operation of the battery. For a once-a-week user, the battery should last a number years.

Continual use of the pump without allowing time for heat to dissipate will significantly reduce the life of the battery!

miniFumpa's battery has the capacity to pump two tyres on a single charge.



The miniFumpa comes complete with a twelve month warranty on all parts. We will repair possible faults free of charge within the warranty period, as long as the faults are caused by material defects or defective workmanship. Warranty claims should be addressed to or the retailer whom you purchased the unit from.



  • miniFumpa won't turn on - Battery requires charging
  • miniFumpa is warm to touch - This is normal. If the unit becomes very hot, turn the unit off and allow it to cool.
  • miniFumpa is making a noise like a siren - Turn the unit off, wait 10 seconds, then turn it back on.
  • Air escapes from around the nozzle - A new seal inside the nozzle is required. Go to for new seal sales.

If the unit behaves unexpectedly, please turn the pump off and contact
