Fumpa electric pump
Australian-based company Fumpa’s smart idea is a self-contained lithium polymer battery-powered compressor that’s ideal for travel.
I’ve put it into service when out riding my gravel bike. At 42 x 74 x 87mm it easily fits into a rear jersey pocket, and at 379g it’s not exactly heavy either.
Fumpa also offers a mini-version for £109, which is even easier to carry when riding.
The unit itself is very well put together with a solid anodised alloy body (and matching valve head). The unit has a digital gauge built-in that reads in psi, kPa or bar, and the screen also shows battery level when you turn it on.
Operation is simple: push-fit the valve head (Presta only), press the button and the compressor simply jumps into action, it’s pretty loud but efficient with it, inflating a 25c clincher tyre to 88psi in 24.6 seconds and a big 47c 650b tubeless gravel tyre to 45psi in 24.3 seconds. It can achieve a max of 120psi.

The Fumpa Pump is effortless to use, and I even found its flow rate was enough to seat a tubeless tyre that had ‘burped’ off the rim when out on a gravel ride and fully deflated.
The pump’s gauge is reasonably accurate, though it generally errs on reading lower than the actual psi. On the gravel tyre a reading of 55psi was, in fact, 61 psi (using a PRO Digital gauge to check).
The pump is charged via a micro-USB cable (550mA) and charging takes close to three-and-a-half hours to fully charge. However, the red charge light doesn’t go off or change when fully charged, which is something I’d like to see.
A fully charged unit was good for 10 inflations from zero to 95psi on a 25c tyre. The reason this little pump packs so much punch is because inside is a 12-volt motor.
The downside of this smart little unit is the price: £149 will buy a top-end track pump.
In its favour, when travelling it’s more convenient and off the beaten track it’s superb for big-volume tubeless tyres where a mini-pump falters, or you empty C02 cartridges quickly.
Fumpa also says that the battery is replaceable and it claims up to six years’ use out of a single battery.
