How this product scores for different use cases
USB 5V power means very low motor output, likely quiet operation. No noise level spec is published to confirm this.
The 8.26x8.26x7.87 inch footprint fits any counter. But it cleans only cups, not full kitchen dishware.
At $56.78 the price is low, but it cleans only cups and cannot replace a standard dishwasher even at the budget tier.
This unit holds only tea cups and small items in a 4L tank. It cannot wash plates, bowls, or family-sized loads.
No premium features, no stainless tub, no sanitize cycle, and no quiet operation spec. Not suited for this use case.
No WiFi, no app control, no delayed start, and no smart home integration of any kind.
Our Verdict
This is a USB-powered cup washer, not a traditional dishwasher. It fits tea cups and small items only.
The 5V USB connection means it works anywhere you have a USB port. That includes power banks, laptops, and desktop computers.
It runs a 20-minute cycle with 360-degree spray. That works for tea sets but not plates or bowls.
At $56.78 the price is low. But standard countertop dishwashers start near $200 and clean full dish loads. This product serves a different and much narrower function.
What We Like
- Runs on 5V USB power. Use it with a power bank, laptop, or any USB charger.
- Built-in 4L water tank. No plumbing or sink hookup needed.
- Tiny 8.26 x 8.26 x 7.87 inch body fits on a desk or small counter.
- 360-degree spray covers cups fully in one 20-minute cycle.
- Priced at $56.78, far below any plumbed countertop dishwasher.
What Could Be Better
- No place settings capacity. Standard countertop dishwashers hold 6 to 10 place settings.
- No sanitize cycle. Most countertop dishwashers over $200 include high-temp sanitize mode.
- No heated dry function. Competing countertop units dry dishes with a heating element.
- No Energy Star certification. Standard full countertop dishwashers often carry this rating.
- No delayed start. Most countertop dishwashers allow you to schedule a wash cycle in advance.
