FAQ

1. Can these fridges run solely on solar panels? All models support 12/24 V DC input and have low ECO power consumption (30‑45 W). Pairing a 100‑W solar panel with a suitable battery (e.g., 100 Ah LiFePO4) can sustain continuous operation for most units.
2. What temperature accuracy is required for vaccines? Most vaccines require 2‑8°C (35‑46°F). The reviewed units maintain temperature within ±2°F of the set point when powered, making them suitable for short‑term transport.
3. How long can the fridge keep items cold without power? Thermal retention varies; users report 12‑48 hours depending on ambient temperature and pre‑cooling. The BougeRV 42 qt retained frozen temperatures for over a week when pre‑chilled and insulated.
4. Is a separate battery necessary? While the fridges can draw directly from a vehicle, a dedicated deep‑cycle battery or portable power station extends runtime and protects the vehicle’s starter battery.
5. Do any models have Bluetooth or app control? Only the EUHOMY 19 qt includes Bluetooth and a companion app for remote monitoring, which can be advantageous for clinicians monitoring vaccine temperature.
