OUMASK 1.5L Portable Washing Machine vs Novlewign Portable Washing Machine

These are two very different machines despite the shared "portable" label. The OUMASK is a real 1.5L top-load washer with a 3000mAh battery and three wash modes, so it can agitate and rinse small loads like underwear or socks. The YIEMEEN (Novlewign) is a tiny ultrasonic puck about 4 inches across that vibrates in a basin of water; it has no tub and no drain. Buy the OUMASK for actual washing. Buy the YIEMEEN only if you want the smallest possible gadget for light soaking on the road. Owners of ultrasonic units like this commonly report weak cleaning and short battery life, and the OUMASK's 4.5 rating from 24 ratings is a small sample.

• Choose the OUMASK if you want a self-contained washer with a tub, a battery and wash cycles for underwear, socks and small loads in a dorm, RV or apartment.
• Choose the YIEMEEN if you want the smallest, lightest option for soaking a few items in a sink or basin while traveling, and you accept that it does not wash on its own.
