Buy the Cooluli Mini Fridge.

Same 4L, 6-can job, but it actually gets cold and keeps working while the Iceman is a coin flip.

What was compared

1. Way fewer stopped working complaints
Iceman reviews repeatedly mention units that stopped working after a few months or barely cooled at all. Cooluli carries 28,186 ratings at 4.3 stars, a track record the Iceman simply does not have behind it.
2. Actually gets cold, not just cool
Cooluli owners describe it hitting 32 degrees, even colder in some cases. Iceman reviewers call it out for having no thermostat and staying too warm to trust with real food.
3. One more way to power it anywhere
Cooluli adds an exclusive USB option on top of 12v AC/DC, so a power bank or laptop port works when there is no outlet. Iceman is stuck with wall plug and car charger only, fine most days but one less option when you need it.
4. Same 6 cans, ten dollars back in pocket
Both are 4L, 6-can coolers with cool and warm modes. Cooluli lists at $49.99 against the Iceman's $59.87 for the identical capacity, so the extra spend buys nothing you can use.
5. Yes, it is cETL certified. Doesn't fix breakdowns.
Iceman leans on a cETL badge and a 1-year Chefman warranty, plus a paid Asurion plan as backup reassurance. That certification proves it won't start a fire, it says nothing about whether the compressor lasts, and reviewers say plenty do not.
