Marine Metal RB-1 Rechargeable Bubble Box Live Bait Aerator – Water-Resistant Portable Air Pump

Meet the Marine Metal RB-1 Bubble Box

The RB-1 is a rechargeable live-bait aerator designed to keep bait lively by delivering steady oxygen in your bucket. Its compact, water-resistant shell is built to stand up to the rigors of a day on the water, from early mornings on the dock to saltwater rinses at the end of a trip.

Flexible performance for real-world use

With four speeds and a pulse mode, you can tailor airflow to your bait bucket size and activity level. A large self-weighted air stone ensures bubbles reach the bottom where bait rests, promoting lively movement that can make handling easier when you’re rigging or casting.

• Up to 15 gallons of aeration capacity per session.
• USB-C recharge means you’ll never need disposable batteries again.
• Can run while charging for extended outings.

Power, endurance, and quiet operation

On a single charge, expect about 40 hours at the lowest speed and roughly 10 hours at the highest, depending on mode. The unit operates quietly, with sound levels around 50–51 decibels, so it won’t crowd the waterside ambience.

• Battery life indicators show battery life, airflow, mode, and charging status at a glance.
• Saltwater and freshwater use compatible, expanding where you can take it.

Design details and what’s included

Included with the RB-1 are a self-weighted air stone, roughly 3 feet of airline tubing, and a 40-inch USB-C charger. The clamshell packaging doubles as a dry box to protect the pump when not in use or during transport.

• Protected from splashes thanks to a water-resistant build.
• Light-weight, portable, and simple to set up in seconds.
