How long does the battery last on a charge?

Eurolite does not publish a runtime figure for the B-20. Expect shorter sessions than a corded machine, and plan to recharge by USB between uses.

How much bubble fluid does it use?

About 400 ml per hour of running. A one-liter bottle covers roughly two and a half hours of continuous use.

Does it come with a power adapter?

Yes, a USB power adapter is included. You can also run it from a power bank or any USB charger.

How far do the bubbles travel?

About 1.7 m from the nozzle. That suits a patio, a small yard or a room, not a large outdoor space.

Is it good for a children's party?

Yes, for a small party. It is light, cordless and easy to carry, but the fluid runs out quickly, so bring spare bubble solution.

Is $65.95 a good price?

It is the best new price across the two stores listing it as of November 6, 2026. There is no long price history to compare against, so check the other store before buying.

Our take on the Eurolite B-20 mini soap bubble machine

The Eurolite B-20 is a small, portable soap bubble machine that runs on USB power from a built-in rechargeable battery. It throws bubbles about 1.7 m and uses roughly 400 ml of fluid per hour. It weighs 0.62 kg and has a foldable carrying handle, so it is easy to move between rooms or outdoors. The best new price is $65.95 at Amazon as of November 6, 2026, and two stores list it new.
