AstroAI Cordless Air Pump Review: Easy Pool Inflation, Even Easier Deflation

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Quick take

A cordless, rechargeable air pump from AstroAI made our backyard kiddie pool a quick job: it filled up in well under a minute in the video. The feature I ended up valuing most was deflation. A second port sucks the air back out, so packing away a wet pool or pool float no longer means squeezing it flat by hand. Two catches: it is loud, and it would not charge from the USB-C to USB-C cable I tried.

What I tested

AstroAI rechargeable (battery-powered) electric air pump with three nozzles
A large inflatable family pool with a canopy
Charging with the included USB-A to USB-C cable and with a USB-C to USB-C cable

What I found

Fast enough, and no cord. I had used a cordless power-tool blower, a foot pump and corded pumps before. The blower nozzle never fit the pool valve well, and a foot pump is not realistic for a pool this size. Speed felt about the same as a corded pump, but without the cable.

The three nozzles included with the AstroAI cordless pump

The thin nozzle is well thought out. Of the three nozzles, the thinnest goes deep into pinch-type float valves, and its tip is slightly soft so it does not damage the valve.

Deflating is the real win. Switch the nozzle to the other port and it pulls the air out. That is handy at home and at the beach, and there is a carry bag for taking it along.

Deflating a family pool with the AstroAI cordless pump

Watch the charging cable. The charging light came on with the included USB-A to USB-C cable, but nothing happened with the USB-C to USB-C cable I tried. A small adapter is included so the USB-A cable can plug into a USB-C charger. If you travel with only a USB-C phone charger and cable, bring the included cable.

Who it’s for

Families who set up an inflatable pool often in summer
Anyone who hates squeezing the air out of floats after a day out
People who want a pump they can take to the beach or a campsite

It is not for bike tires or anything that needs high pressure, and it cannot be used as a power bank.

Watch the video

The video is in Japanese. Inflating the pool starts around 1:20, deflating around 2:40, and the charging cable issue around 8:40.

Limitations

It is loud. Outdoors it was fine, but it may bother people nearby in quieter places. I did not measure battery life or exact inflation times.

Products

I could not find this exact AstroAI cordless pump on Amazon Japan when writing this, so there is no product link. Look for a rechargeable pump that both inflates and deflates, and check which charging cables it supports.
