This is the ECOPLUSE air pump from OneTigris (ワンティグリス). I have used it a couple of times to check its operation. The "large nozzle" is missing from the three nozzles. Please refer to the Amazon URL below or the description for product details. https://www.amazon.co.jp/dp/B0DH2GZZCD/ Please note that the outer box may have some imperfections. There are no noticeable stains or scratches, but please refrain from purchasing if you are concerned about minor details. Product Description 【Lock Mode & Portable】Travel lock function: Long press for green light flashing - unlock, long press for red light flashing - lock. You can carry it with peace of mind without worrying about accidental automatic start. It also comes with a large-capacity storage bag, and accessories can be stored together for convenient portability. Please unlock the travel lock when using it for the first time. 【High-Power Electric Pump】With a super power of 5.5Kpa and 450L/min, this portable air pump can quickly inflate and deflate in less than a minute. No need to manually pump, saving time and effort, making outdoor activities more convenient. 【Large Capacity 4000mAh Battery】Built-in 4,000mAh large-capacity battery and Type-C charging style enable fast charging. It has both inflation and deflation functions, and can supply and exhaust air for inflatable gear needed for camping, making it useful from the beginning to the end of your camping trip. 【Note】It is not recommended to use a high-speed charger (e.g., 9V, 12V) as it may cause circuit damage. The battery has a self-protection function, so it is recommended to charge it once a month to maintain battery activation. This can prevent discharge failure.
