Bluetti has been on a winning streak lately, releasing a series of excellent power plants and solar products. I’ve already suggested that the new Elite v2 range offers arguably the best mid-sized power plants on the market. The Chinese energy storage company is now trying to innovate with the Pioneer Na, announced at IFA 2025 in Berlin. Bluetti claims it is the world’s first sodium-ion battery, designed specifically for use in subzero temperatures. So, does this innovation deliver the performance and overall quality that Bluetti is known for? Popular science was among the first to get its hands on a review unit, and here’s what we think.

How we tested the Bluetti Pioneer Na

The first thing I should note is that I used the Pioneer Na during a particularly mild September, so the opportunity has not yet arisen to test its promise of freezing functionality. But I ran it full force a few times, checking its performance specs against those claimed by the Bluetti and seeing how it handled different combinations of appliances and appliances, like a phone, laptop, coffee maker, hair dryer, electric drill, and so on. I also judged it on factors like port variety, portability, design, and durability, and compared it to the scores of powerhouses I’ve reviewed previously.

Why should you trust me? I’ve spent nearly 30 years using solar and mobile equipment in a hobby and professional capacity, and have tested dozens and dozens of portable power stations from all the major manufacturers. This first-hand experience has inspired nearly a decade of reviewing solar generators for companies like Popular science, Popular mechanicsand many more.

Na Na Na Na, Na Na Na Na, Hey Hey Hey… Hello?

“Na” is the symbol for sodium, and unlike a lithium battery, which cannot charge below freezing or discharge below 4 degrees Fahrenheit, a sodium-ion battery can operate at significantly lower temperatures, charging down to 5 degrees, discharging down to -13, and storing stably down to -20. That being said, operating in particularly cold temperatures diminishes its capabilities somewhat, reducing its discharge capacity by up to 20%.

Another advantage of choosing sodium concerns durability. Sodium is much more abundant and easier to obtain than lithium, although it does not offer the same energy density. As a result, a Na-ion portable power station will be slightly larger and heavier than a lithium model of the same capacity.

The construction

One of the qualities I like most about Bluetti is their sturdy and stylish design, and the Pioneer Na confirms this. It sports an attractive new blue color that I suspect will now distinguish the brand’s sodium lines from lithium. And it’s a sharp aesthetic.

And as I’ve said before, one of my favorite aspects of Bluetti’s recent powerhouse releases is how sturdy the craftsmanship is. I’ve tested no shortage of powerhouses that feel like they’re made of cheap plastic or have alarming interiors, but that’s not the case with the Pioneer Na. It is solidly constructed and its lifespan of over 4,000 cycles places it among the leaders in the industry.

Performance

Based on my testing at non-extreme temperatures, the Pioneer Na meets its marketed specifications. It was able to power multiple devices at once while pushing it to the limit of its operating capacity, and then it didn’t seem to struggle when brief power surges forced it into lifting mode. Its charging speed is lightning fast, going from zero to full in just over 40 minutes. And it generally performed as I would expect a lithium model to.

Its 900Wh capacity isn’t huge, but it’s the perfect size if you’re looking to withstand a few hours of power outage or need a convenient, portable power source for charging devices or using small appliances while camping. With four AC outlets, five USB-A and USB-C ports of varying output power, and a car outlet, it has plenty of outlet options relative to its capacity.

So, who should buy the Bluetti Pioneer Na?

The Pioneer Na performs as well as any lithium station of similar capacity from the company, so when it comes to general use, it’s ideal for anyone who needs a mid-sized power station that’s larger than a small power bank but compact enough to still be very portable. It’s the kind of thing you take camping to run a few appliances, or have at home for short power outages or when you need a power source where there isn’t an outlet.

But it becomes especially attractive if you plan to use or store it somewhere where the temperature drops below freezing. I was disappointed by the power plants not working in cold weather, so to that end its sodium chemistry is a major plus.

The Bluetti Pioneer Na is set to release on October 15 (price to be determined), just in time for the winter chill.
