The M01 is a 20L travel compression bag with a built-in electric pump. Close the airtight zipper, open the valve and hold the button for two seconds; the pump pulls the air out and packs clothes down so a week's worth fits in a carry-on. It is lighter and simpler than hand-roll or hand-pump bags because there is no separate pump or power bank to pack, and it folds flat when empty. The catch is the lithium battery: it must fly in the cabin, never in checked luggage.

Rated 4.5 out of 5 from 977 ratings, buyers mostly like how much space the built-in pump saves and how easy it is to use. The main complaint is the cabin-only battery restriction.
The M01 is a 20L travel compression bag with a built-in pump. It compresses clothes to a fraction of their size, so a week's worth of clothing can fit into a carry-on.
The pump runs on a built-in lithium battery, so it needs no cables or power bank. Close the airtight zipper, open the air valve, and hold the button for 2 seconds. The pump removes the air automatically and seals the clothes compact and ready to pack.
The bag is lightweight and folds down when empty, so it fits inside another bag without taking up space. It is used for travel, business trips and backpack packing. The built-in lithium battery means it must be carried in cabin luggage only and is not permitted in checked baggage on flights.
