JILONG | Rechargeable Electric Pump | 29P571

The Jilong Avenli Rechargeable Electric Pump (Model 29P571) is engineered as a high-performance, cordless inflation and deflation system tailored for heavy-duty consumer applications where access to grid power is unavailable. Encased in a rugged, ergonomically balanced impact-resistant ABS shell, the pump houses a high-torque DC motor paired with an optimized centrifugal turbine impeller. Unlike low-capacity pocket micro-pumps, the 29P571 is designed specifically to output a massive volume of airflow per minute at a higher static pressure, allowing it to efficiently inflate large-scale inflatables—such as king-sized queen airbeds, multi-ring family lounges, and heavy-gauge inflatable boats—without slowing down or overheating. The hallmark engineering advantage of the 29P571 model is its high-capacity, integrated lithium-ion rechargeable battery cells. The internal power matrix can be replenished via a standard USB charging port using any common wall block, vehicle adapter, or portable power bank. A built-in LED battery life indicator lets users monitor the remaining power status at a glance. Equipped with a dual-port design, the front housing serves as the high-velocity inflation terminal, while the top intake vent converts into a powerful vacuum. Swapping the nozzle to the top port allows users to actively vacuum-deflate gear, collapsing thick vinyl down to flat, factory-level proportions for neat storage.
