Electric Countertop Composter Comparison

We reviewed five electric countertop composters directly on their Amazon listings on July 30, 2026. The specs, pricing, and performance claims below come straight from each seller's product page, not from independent lab testing.

Our Picks

Which one fits your kitchen?

Each pick separates what the seller lists on Amazon from BlackGold's own editorial reasoning, so you can see where the facts end and our judgment begins. We did not test these units. The reasoning compares the listed specs against the kind of household each one suits, and every pick comes with its drawbacks.

Best for a small apartment

Ouaken 4L Electric Composter for Kitchen — White

Ouaken 4L Electric Composter for Kitchen — White

$219.99

Who it’s for: One or two people, a compact kitchen, and a unit that may run while someone is in the next room.

Seller-listed (Amazon, not tested by us)

  • Capacity: 4 L, the smallest tier of the five
  • Noise: seller claims below 40 dBA — the lowest numeric claim in this comparison
  • Modes: Crush, Ferment, Clean
  • Filter: Large-capacity carbon filter — the seller says up to 5 months of use

BlackGold editorial reasoning

A small bucket suits a small household: scraps get processed before they sit, and the lowest stated noise figure matters most where the unit is a few steps from your sofa or bed. Growell lists no dBA number at all, so it cannot be compared on noise. The 4L white and black Ouaken listings show identical specs, so we point to the lower-priced one.

Drawbacks to weigh

  • Footprint is not captured in our listing data. Check the dimensions on the Amazon page against your counter and cabinet clearance before ordering.
  • The dBA figure is the seller’s claim, not a measurement we took.
  • Three or more people will fill 4 L quickly.
  • The carbon filter is a recurring cost.

Not for: Households of three or more, or anyone who wants to add scraps all day.

Best for a family kitchen

GEME Smart 19L Electric Composter for Kitchen

GEME Smart 19L Electric Composter for Kitchen

$899.99

Who it’s for: Three or more people cooking regularly, with scraps arriving throughout the day.

Seller-listed (Amazon, not tested by us)

  • Capacity: 19 L, versus 4 L to 5.5 L for the others
  • Run mode: continuous, add scraps anytime, with no selectable cycles
  • Seller describes up to 11 lb daily capacity and 6–8 hour processing
  • Filter: permanent built-in filter, which the seller says never needs replacing

BlackGold editorial reasoning

Cycle-based 4–5.5 L units make a family plan around batches. A 19 L continuous unit is the only one here where that planning goes away. It costs $899.99, but per listed litre it is not the most expensive option: about $47/L against $55/L for the 4 L Ouaken. Listed litres are not usable litres, so treat that as a rough guide. On a tighter budget, the 5.5 L Ouaken OK-255 at $279.99 is the step-down option, with Standard, Quick, Crush, Clean and Store modes.

Drawbacks to weigh

  • The highest price of the five at $899.99. Reconfirm the price and any coupon on Amazon.
  • “True compost”, 95% reduction and cleaning-free use are GEME’s own claims, not independently verified.
  • No dBA number is listed, only “whisper-quiet”.
  • Footprint is not captured in our listing data. A 19 L unit needs real counter or floor space, so check the dimensions.

Not for: One- or two-person households, or anyone who is price-sensitive.

Best for a lower starting price

Ouaken 4L Electric Composter for Kitchen — White

Ouaken 4L Electric Composter for Kitchen — White

$219.99

Who it’s for: Readers who want to try countertop composting without a large outlay.

Seller-listed (Amazon, not tested by us)

  • Price at review: $219.99 (seller-displayed list price $279.99)
  • Availability: In Stock — ships from Amazon, sold by Ouaken LLC
  • Capacity 4 L; modes Crush, Ferment, Clean

BlackGold editorial reasoning

This is the least expensive exact model among the five that were available at review. It is also our small-apartment pick: the same model wins on both counts because the black 4L listing shows the same specs for more money. A low price is only good value if the size fits. At about $55 per listed litre, it is not the cheapest way to buy capacity, so buy it for a small household rather than as a bargain on volume.

Drawbacks to weigh

  • Displayed list prices are the seller’s reference points, and discounts change often.
  • Price was reviewed on July 30, 2026 and may differ now. Check Amazon for the current figure.
  • Cheapest does not mean best for a household of three or more.

Not for: Larger households.
