How Long Will the Bluetti EB3A Run a 12V Car Fridge?
Updated 2026-10-17 · Yes
About 14 hours. The Bluetti EB3A stores 268Wh, and a 12V car fridge averages about 18W because it cycles on roughly 40% of the time.
The numbers
| Battery capacity | 268Wh (LFP) |
|---|---|
| Usable energy | 247Wh (92% via 12V/USB DC output) |
| Continuous AC output | 600W |
| Surge rating | 1200W |
| 12V car fridge running watts | 45W |
| Startup watts | 60W |
| Average draw | 18W |
| Estimated runtime | 14 hours |
| Energy per day of typical use | 432Wh |
268Wh × 0.92 = 247Wh usable ÷ 18W average = 13.7 hours

Recharging with solar
The Bluetti EB3A accepts up to 200W of solar input. In real conditions that harvests about 750Wh on a sunny day (5 peak-sun hours).
Solar can keep up. A 12V car fridge uses about 432Wh a day at 24 hours of use, so with enough panels and good sun the Bluetti EB3A can run it indefinitely.
Tips
- Compressor coolers like Dometic, ICECO and BougeRV plug into the 12V car port, which skips inverter losses entirely.
- Running it from the Bluetti EB3A’s DC port instead of the AC outlet avoids inverter losses: about 19Wh more usable energy.
- The Bluetti EB3A uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
