I inflated a baby pool... 1 by 1 with 2 layers... it inflated it in 1 minute and deflated it in half a minute... As for noise, it's like a hair dryer on medium setting... Seems fair to me

Quite a good pump. Its battery has lasted a long time. I have inflated and deflated the mattress several times. And it still has battery. It does the job

I left it charging in the socket for two days and the lights on the battery remained stationary, so it probably doesn't charge the battery.

Until now I had only tried pumps powered by a car lighter and/or socket. This one is even more powerful, something I did not expect. When I saw its power, I thought the battery wouldn't last even for a second air mattress. I inflated a double mattress, two singles, two fairly large individual inflatables for the kids, and out of the 4 lights, only one went out.
Another great convenience is the deflation, as it deflates things so easily instead of you wrestling Greco-Roman style with an inflatable turtle, let's say, and they fold up very easily.

I bought it to assist me with travel/luggage.
As for size, it's small, but it has a serious size that doesn't work for keeping it in the backpack.

As for whether the air escapes from the bag with the clothes, it does its job well. It needs another 5-10% to be perfect.
Definitely, for its size, it is very good!

Well... I started very skeptical because I have 5 different brands of sleeping pads and I was sure it wouldn't work for me. However, it inflates very quickly, from Klymit and Robbens to the cheap 20cm thick pads from Jysk and Outwell. It comes with three spare parts, which is enough for what I had, even for inflatable beach mattresses. It has a type C charging and after playing for about 10 minutes, the battery is still at 4/4 and it has inflated 4 single and 1 double sleeping pad. It is of medium quality, neither tactical nor Chinese, somewhere in the value for money range, but decent. If you open the valve, the sleeping pads deflate perfectly without any cells. It is lightweight for camping, but I wouldn't carry it for hiking. If you are going to inflate a 10-breath Klymit, it's not worth it, but if you have to inflate a double or several 10cm ones, it's worth every euro.

It produces about 250 liters of air per minute, (inflates a mattress 2x1.5x0.25 in about 3 minutes) its battery lasts about half an hour of continuous use and charges in about 4 hours. It can also be used for deflation (the nozzles also work for air extraction).

Excellent!
