Features of the Duotone lazepump
The Lazepump comes in a neat and handy hard case ("...a beauty case has arrived for them..."), in which all the accessories are neatly and separately stowed away. What's more, you can easily pack up all the parts again without having to attend an origami workshop lasting several days. The pump has its own carrying handle and the pump's suction nozzle is fitted with a filter to protect the compressor from sand and dust. The scope of delivery includes three replacement filters, a charger and various adapters that cover the most important connections for almost all kites, wings and SUPs. The adapters are screwed firmly and securely onto the pump hose. The hose can also be flanged to the pump so that it runs to the board without tension.
Duotone lazepump: Fast and durable
The desired pressure is quickly set on the easy-to-read display, with a maximum of 20 psi possible. We select 15 psi, which is usually more than sufficient for SUP boards. This is also standard for our pump tests, as 15 psi is the maximum pressure that can be set for some pumps.
The air pump works automatically in two stages: First with a blower, which usually fills the board with air very quickly. Then with a compressor for the necessary pressure. The Duotone pump starts up like a household hairdryer at 380 volts and inflates the board completely in 1:45 minutes. We have experienced this faster, but the sound frequency is not shrill, but within a tolerable spectrum. The compressor then switches on seamlessly and gets to work all the more diligently. With a - as with all electric pumps, not quiet - but comparatively warm humming sound, the board is quickly brought up to 15 psi. The stopwatch stops at a total of 11:23 minutes. This is a good value compared to previously tested pumps and the noise level is also at the lower end of the range. However, you won't be making any friends on the beach with this pump, as it also requires backsiphoning.
This is how many boards the pump can handle
We inflate our rather voluminous test board (paddle board Touring 12'8''x31'') two more times, only then is the battery empty. On the last run, the inflation takes one minute longer, which is probably due to the decreasing battery level, but remains a good value. Three boards are therefore possible with the battery, and a cable for the 12-volt socket is also included.
2 minutes 50 seconds for one wing
For the test, we inflated a Duotone Unit 2025 to 7.5 psi, which is exactly the recommended average value for the range. The wing was ready for take-off in 2:50 minutes. This speaks in favour of the specified number of 8 wings in total, which the pump should easily manage on one battery charge, as it took a good half hour to inflate the three SUP boards.
Test summary of the Duotone Lazepump electric pump
The new Duotone leap pump is completely convincing: from the features to the performance. Our current test SUP is quite large at 12'8''x31'', but the pump still manages to pump up to a solid 15 psi three times in a row on one battery charge. Extrapolated to significantly smaller wingfoil boards or wings that require less pressure, the pump should be able to pump at least 6 wingfoil boards or 8 wings.
