I tried this Bluetti power station with wheels – now every other charger feels outdated

It took humans some 300,000 years to figure out that rolling something was easier than carrying it. Just as it’s hard to believe that the iPhone hasn’t been around for 20 years yet, it’s just as hard to believe that we’ve only been using wheels for some 6,000 years. 

And it’s odd how few power station manufacturers put wheels on their units (and when they do, they feel like a compromise). They still expect you to lug around 80-pound lumps like a prehistoric cave dweller.

Bluetti solves this with the Elite 400 — a power station that’s built around wheels that would make the Flintstones sit up and pay attention.

What’s the deal with the wheels?

OK, so why does the Elite 400 need wheels? 

Well, this is a big system, holding a massive 3,840Wh of power in a big bank of lithium iron phosphate (LiFePO4) cells. That’s enough to run a refrigerator for over three days, a hair dryer for 90 minutes (which, if you have as much hair as I do, you won’t need!), or your RV air conditioner for 9 hours.

That’s some workload for a portable power station, and one that the Elite 400 handles effortlessly. I’ve connected all sorts of devices to mine, from high-resistance loads like heaters and ovens to devices that need a stable output, like computers, and the unit has performed flawlessly.

Take all that, and then add an inverter that can push out 2,600W of AC power (3,900W surge), and you’re looking at a unit that measures 17 x 11 x 41 inches and weighs a whopping 86 pounds. That’s well beyond the 51 pounds that the National Institute for Occupational Safety and Health (NIOSH) recommends.

There are four 20A AC outlets (the unit photographed is the UK version, so the output options differ) for mains-powered items, four USB ports (two 15W USB-A and two 100W USB-C), and a 12V/10A DC output port.

The unit has a color LCD similar to the one Bluetti uses on other power stations. It shows enough information without being overwhelming. If you want to take a deeper dive, you need the Bluetti app, which is up there among my favorites for controlling power stations. 

You can start to see why this needs wheels! 

Charging options

As for inputs, the Elite 400 can take AC, which will charge it from flat to 80% in 1.9 hours and to full in 2.5 hours. If you mix AC and add 1,000W of solar, this recharge time is slashed to 70 minutes for 0 to 80% and 1.8 hours to full. 1,000W of solar power alone takes 6 hours to fully charge the unit.

If you choose the slow, quiet 800W AC charging option, it’ll take just under four hours — but you can sleep in the same room as the power station without worrying about a fan kicking in to disturb your slumber. 

This slower charging option also helps prolong battery life, though with a five-year warranty and LiFePO4 batteries’ known longevity, it’s not a major concern.

For more than the occasional vehicle recharge, I recommend Bluetti’s Charger 2 1,200W DC-to-DC charger, which slashes recharge times down from over a day using your vehicle’s built-in 12V outlet to only a couple of hours. 

Lugging the station around

The wheels are a joy to use on all surfaces, from loose gravel to carpeted floors. Any wheels are better than having to carry a lump weighing close to a hundredweight, but these wheels cope with pretty much any surface you throw at them (except mud… I don’t recommend dragging your power station over mud!).

And wheels need some sort of handle, and the telescopic handle on the Elite 400 is perfect for the job. 

It’s not so weak that I expect it to snap or break in two at any moment, but not so over-engineered that it’s unnecessarily bulky and cumbersome. Oh, and the handle is comfortable to use — take note, other companies that put uncomfortable handles on things. 

ZDNET’s buying advice

The Bluetti Elite 400 is one of those portable power stations that’s perfect for a number of applications, from general home use to emergency power (it can switch to battery before any connected devices notice), to carting around in an RV or camping.

It’s an all-purpose unit.

You do need to be aware of the weight because 90 pounds is a heck of a weight to do anything with other than roll it around.

But you also get close to 4kW of power at your disposal and the ability to handle 20 Amps of load. Anything that you can plug into a standard outlet will work with the Elite 400, making it a no-compromise system.

The price is also good. 

At a regular price of $1,899, it’s very competitively priced for a unit that delivers that much power. Right now, over on Amazon, you get 32% off the list price, bringing the price down to an extremely competitive $1,299. At that price, this is a steal because you’re hard-pressed to find a good 3kW portable power station for that price.
