The ThreeH model runs off USB power with dual cooling and heating, allowing beverages to be kept cold or warm at a desk. It’s ideal for computer workstations or gaming setups where quick access to a drink is convenient. Caution: small capacity means it’s best for one or two cans at a time, not full meals.

ZLPTEAM Insulin And Medicine Cooler
This USB-powered cooler is designed for secure medication storage on the go. It maintains a stable temperature with continuous power from a USB source such as a car charger or power bank. Best for transportable medication storage; however, it relies on ongoing power, so it’s less suitable for environments with unreliable power sources.

This dual-function fridge stores skincare, cosmetics, beverages, and small snacks. It holds up to six 12 oz cans and flips to cool or warm as needed.

Limitation: basic dial controls may be less precise than digital models.
Frigidaire Portable Top Opening Mini Cooler
This renewed model provides flexible storage for up to 6 cans or 4 liters, with insulation and thermoelectric cooling. It’s suitable for skincare products, snacks, and small beverages during travel or dorm life. Better for users who want a less expensive option with reliable insulation. Limitation: performance may vary in non-ideal ambient temperatures, and “renewed” status may imply cosmetic wear.

It supports 12/24V DC and 100–240V AC, suitable for home use or vehicles with vehicle battery protection. Choose this if you need a more expansive mobile cooling solution; however, it takes more storage space and carries higher complexity than smaller models.
