How to choose
Battery life per charge
Battery life is the first number to compare, but the listings state it differently. The Beyio runs about 30 days on a full charge, the Msxcse pumps up to 8 five-gallon bottles per charge, and the Redsack covers 15 five-gallon jugs, or 75 gallons, per charge. The FLOWEBB lists a 1200mAh battery, so compare the stated figure for each pump against how many bottles you use. A larger stated figure suits heavy daily use.
Flow speed and modes
Flow speed decides how fast a glass fills. The Redsack fills 200ml in 3 seconds, and the FLOWEBB pushes up to 2200ml per minute with a dual-motor system. The FLOWEBB adds 3 modes: a 15-second timed flow, a 30-second timed flow, and continuous flow. The Beyio stops on its own after 60 seconds, with a 3-second press and hold for continuous flow. Match the flow and modes to glasses, kettles or large kettles.
Fit and bottles
Fit decides whether a pump sits on your bottles. The Beyio fits 2.16-inch screw cap bottles and bottles from 1.5L to 18.9L. The Msxcse fits standard jugs from 2 to 5 gallons with 2 silicone pipes at 21 inches. The FLOWEBB fits 2 to 5 gallon jugs with a 2.16-inch neck. The Redsack and 3JINSERDON fit 5-gallon bottles. Check your bottle neck and size before you buy.
