Review on Quick-Fill Electric Air Pump, 4000mAh Rechargeable Air Mattress Pump by Dr.meter - Perfect for Outdoor Camping, Inflatable Couch Bed, Boat, Pool Toys, Snow Tube, and Swimming Rings - USB Powered by Brittany Sanchez

A few things to consider before purchasing this pump: The on/off switch is in a very awkward position. Of all the places the switch could be, on this pump it's right next to the injector. Has the person who developed this pump ever tried to use it? It's like having to turn on the pump before inserting the nozzle into the item you want to inflate. Be aware of nozzle sizes, especially if you are inflating something large and/or have a large opening to insert the nozzle. The nozzles are short and of the 3 that come with the pump, 2 are for smaller holes. It is possible to stack one nozzle on top of the other to increase the length, but if you are inflating something large, using a smaller nozzle to extend the larger one will also slow down the inflation speed of the inflatable as there will be less air. can happen. If size isn't an issue for you, consider something larger. This pump is short, so it will most likely need to stay on the whole time you're inflating something big. A larger pump can be placed on the floor and still reach the fill hole. While the pump appears to work well, this is a problem for what I bought it for - inflating an air mattress. If you're buying it for small inflatables like pool toys it might be fine, but the location of the power button can still be an issue.
