Will it work with my vacuum storage bags?

It fits most bag valves on the market, with a 1.64-inch exhaust port. Check that your bags have a round valve of similar size; flat or very small valves may not fit.

Does it need a power outlet?

Yes. It plugs into a socket and runs on mains power, so there is no battery to charge. That makes it best for home use or places with power.

Can it seal food or inflate air mattresses?

No. It is made for pulling air out of vacuum storage and seal bags. It does not heat-seal food bags or inflate inflatables.

How is it better than a hand pump?

It removes air faster and with no manual effort. You plug it in, open the switch and hold it to the valve while it compresses the bag.

Is it good for travel?

It is compact and easy to pack, and it helps shrink luggage contents. Remember it needs a power outlet, so it is less useful where no socket is available.
