Fast two-way inflation: the manual hand pump delivers air on both the up and down stroke, cutting inflation time and effort for rafts, inflatable beds and other items. High-pressure performance: engineered to generate the pressure needed for large inflatables, the pump makes it easier and quicker to assemble inflatable boats, air beds and swimming pools. 4 L air capacity: a larger chamber moves more air per stroke, reducing the number of pumps required and speeding up the job. Multiple nozzle compatibility: includes a set of nozzles to fit a variety of valve sizes so you can use the same pump for different products. Durable, wear‑resistant construction: made from high-quality materials to withstand repeated outdoor use at the campsite, beach or on the water. Why you need it Saves time and energy when inflating bulky items that would otherwise take many slow strokes. Works with most common valves thanks to the included nozzles, eliminating the need for multiple pumps. Built to last so it performs reliably across seasons and trips. Practical applications Camping: quickly inflate air mattresses and sleeping pads at the campsite. Beach and pool days: fast inflation of pool toys, floats and inflatable loungers. Boating and water sports: efficient setup of rafts and inflatable boats before hitting the water. What it does for you Faster inflation with less physical effort thanks to two-way operation and a 4 L chamber. Reliable high-pressure output for properly sealed, ready-to-use inflatables. Versatile and robust design that adapts to different products and withstands outdoor conditions.
