Petbank Automatic Fish Feeder — 16-Grid Aquarium Feeder (Black), USB Rechargeable & Moisture-Proof Portion Control

Designed for hobbyists and small-scale aquariums, this feeder replaces one-size dispensers with 16 separate compartments that hold individual servings. Its sealed mechanism keeps pellets and powders dry, while the smart timer and LCD let you schedule feedings or trigger manual portions. The unit mounts via an adjustable clamp or suction cup to fit covers and rim styles, and a built-in rechargeable battery powers weeks of uses after a single charge.

How accurate is the portion control and what foods will it accept?

The Petbank feeder uses 16 individual grids to measure servings precisely, with each cell holding up to about 2 g. This arrangement reduces dosing errors common in single-chamber designs and supports variety in aquarium diets.

• 16 separate grids for up to 15 scheduled meals
• Each compartment stores roughly 2 g for consistent portions
• Compatible with pellets, granules, powders, and small strips
• Not suitable for flakes or larger shrimp feed

Can I schedule multiple daily feedings and change frequency?

The unit’s LCD timer allows up to three feedings per day, and you can select how many grids release per feeding. You may also set the feeder to operate every day or at intervals of two to four days, letting you tailor feeding frequency to your fish’s needs.

• Program up to 3 feedings per day from the LCD interface
• Release 1–3 grids per feeding to scale portion sizes
• Repeat schedule daily or every 2–4 days for flexible routines
• Manual feed button for instant dispensing when you want to interact

What mounting options are available and how does the moisture-proofing work?

Petbank gives two mounting methods so you can attach the feeder to different aquarium setups: an adjustable clamp for rims and a suction cup for glass or covers. The dispenser’s outlet closes automatically after each release, preventing humidity and water splashes from jamming stored food.

• Adjustable clamp base for different tank rim sizes
• Suction-cup option for glass or cover surfaces
• Auto-closing outlet keeps food dry and reduces clogs
• Sealed design protects pellets and powders from moisture

How long does the battery last and is charging convenient?

Equipped with a 700 mAh rechargeable battery, the feeder fully charges in about three hours and can operate for one to two months depending on program settings. Charging uses the included USB type-C cable so you won’t need disposable batteries.

• 700 mAh internal battery for extended runtime
• Approximately 3-hour full charge with USB-C cable included
• One to two months of typical use between charges
• No frequent battery replacements required, energy-efficient

Who is this for: The Petbank Automatic Fish Feeder suits casual aquarists, busy pet owners, and vacationers who need reliable, measured feedings without daily attention. It’s ideal for freshwater and community tanks that use pellets, granules, powders, or small strip foods, and for anyone who wants programmable control and moisture protection in one compact device.
