Intex QuickFill Electric Air Pump

After I fully charged the battery before first use as recommended by the instruction manual, I atempted to inflate an Intex Stargaze Tube. After inflating, I decided to use the pump to deflate the tube, however, during deflation, it was then that I noticed the motor seemed to be dying. Before any sort of significant deflation had occured, the pump had already died and needed to be recharged. UNACCEPTABLE!!!! I bought this to inflate two Intex inflatable tubes and this barely inflated one on a single charge. To make matters worse, I shipped this item internationally and I would probably pay more than what the item itself cost to return it. Now I'm stuck with a pump that can not fulfill the main reason it was purchased. I don't know if the unit I got was defective, but based on my experience with this pump, I'd advise anyone to avoid purchasing. Updated on Wednesday the 10th of April; In response to anyone who may think that the pump was not charged properly before my first attempt, I attempted to use this pump a second and third time, each time, leaving the unit to charge overnight and I got the exact same results each time. It inflated 1 Intex Stargaze Tube and while attemtping to deflate said tube, the motor died shortly after and the tube had to be manually deflated. So I have two options. Either I throw this pump into the trash where it belongs or I keep it to use as a paperweight.
