I stuck this power station in a freezer to test its subzero claims - here's what happened next

ZDNET's review covers the Bluetti Pioneer Na, a 1,500 W / 900 Wh portable power station that uses sodium‑ion batteries to perform and be safely charged in extreme cold (charging down to -15°C and operation to -25°C). The article highlights fast AC charging (80% in ~45 minutes), a wide range of outputs, low standby consumption, long cycle life (~4,000 cycles), and notes tradeoffs including larger size, greater weight (~35.3 lb), lower energy density, and higher cost compared to lithium‑ion alternatives.
