About this product
The ZKSCool CB02 is a compact, battery-powered thermoelectric cooler built for insulin vials and pens and other temperature-sensitive medication. The lid is the control panel: a ZKSCool logo, the words Portable Cooler, a power icon, AUTO, plus and minus touch keys, and an LCD window that reads live internal temperature. Inside, a removable white basket with vertical slot dividers holds vials or pens upright, and the base housing carries a ventilation grille. A black zippered insulated carry bag with a clear front label window is supplied with it. Retail listings for this model publish: 0.6 L / 36.6 cu in capacity, an adjustable range of 36-68 F (2-20 C) with a one-touch lock at 41 F (5 C) to stop accidental changes, semiconductor (thermoelectric) cooling, up to 8 hours of cooling per charge, external dimensions of 9.9 x 4.4 x 4.5 in, an internal compartment of 7.06 x 2.87 x 1.81 in, and interior capacity for up to 20 insulin vials, 12 small pens, 8 medium pens or 3 extra-large pens. The retail configuration is the unit plus a removable lid, home charger, car charger (12 V), carrying case and rechargeable battery. Trade-press coverage of the brand at CES 2025 described a 12 V cooling chip with an aluminium inner tank and an over-temperature alert. Who resells it: pharmacies and diabetes-supply retailers, DME and home-medical dealers, travel and outdoor retailers, fertility-medication channels, and health e-commerce. It sells year-round with a summer-travel peak, and the carry case makes it presentable as a gift or care-package item.
