Why Your Old Battery Fails in January (And How Sodium Fixes It)

It is currently -10°C in parts of the Midwest, and we are seeing a flood of forum posts asking the same question: “Why won’t my power station charge in the garage?”

The answer lies in chemistry. Traditional Lithium-ion batteries have a safety mechanism that prevents charging below freezing to avoid permanent damage. But in 2026, BLUETTI has solved the “Coldgate” problem with our new Sodium-Ion (Na-ion) technology.

The -20°C Difference

Unlike traditional units that turn into expensive paperweights during a blizzard, the new BLUETTI Pioneer Na retains over 80% of its capacity even at -20°C (-4°F). It is the first power station designed specifically for:

• Winter Camping: Keep your electric blanket running in a snowed-in tent.
• Emergency Car Kits: A battery that can actually jump-start your car after sitting in the trunk all night.
• Ski Lodges: Reliable off-grid power for unheated cabins.

Pro Tip: If you live above the 40th parallel, swapping your emergency kit to Sodium-ion isn’t just an upgrade; it’s a safety necessity for this winter.
