ZDNET's key takeaways

A very transportable power station now $399 on Amazon
Decent 512Wh capacity and 600W output (1,200W surge)
Designed to fit into an (included) backpack built to carry heavy loads

Power stations are all the rage and finding their way into homes, RVs, cars, trucks, and even tents. They are the perfect way to transport AC power to places where there isn't a convenient power socket.

Until now, however, transporting them has meant rolling them on built-in wheels or taking the less glamorous approach of lugging them with a built-in handle. This is OK for short distances but rapidly becomes inconvenient if you need to transport the power station more than a short distance. Perhaps you're taking power to a site inaccessible by road, due to an emergency, or because you want to provide plenty of power for a group of people.

At the core of the Handsfree 2 is a 512Wh power station, but rather than being the usual box shape, this one has been constructed into an ultra-thin form factor. However, that ultra-thin design doesn't mean that you have to compromise.

The power station is an ultra thin design, and quite unique.

You're still getting a power station with an LCD panel to show you all the important information, an AC outlet good for 700W of continuous output (1,200W surge), two USB-C ports, a USB-A port, and even advanced features such as UPS-level switching and pass-through charging.

The LCD is clear and bright, even in sunlight.

The charge capacity is enough to recharge a smartphone about 15 to 20 times, a laptop or drone half a dozen times, and an action camera such as the GoPro about 30 times. When you get back to an AC outlet or a solar panel, the Handsfree 2 can be recharged rapidly -- 45 minutes to reach 80% capacity -- so you can get back on the move again.

The outputs are on the side and easily accessible.

Then there's the backpack. This 60-liter backpack (or 3,600 cu in) is designed to carry not only the power station but whatever else you need, up to a maximum of 30kg. If you're not used to backpacking, let me tell you -- that this is a fair load.

The power station fits into the back of the backpack, close to the harness, keeping the weight against your body, in the most ergonomic position. There's a side panel that enables the power station to be accessed and used without taking it out of the backpack.

There are two layers inside the backpack, one for clothes and flat items such as laptops.

Layer one of the backpack is for clothes and items such as laptops.

The next layer has dividers for cameras, but these dividers can be removed.

The second layer features removable dividers.

The backpack is constructed from splash-resistant Oxford fabric, waterproof zippers, and a rain cover that can handle medium to heavy rain.

The zips are waterproof and slide easily.

The rest of the free space in the backpack can be used for other essentials such as camping or photography gear and emergency supplies.

So what's this kit like?

Starting with the power station, the 512Wh capacity checks out for me, as do the rated outputs. While a 700W AC output isn't going to handle super-heavy loads like large kitchen appliances, it's enough to handle small power tools, lights, laptop chargers, and the like.

The power station's display is clear and easy to read, offering an at-a-glance overview of what the power station is up to. All the controls are conveniently placed on one side of the power station so they can be accessed through the flap on the backpack. There's a handle for lifting and carrying the unit about.

As far as power stations go, it's a great unit that lives up to my expectations and the Bluetti name.

Next, the backpack.

The backpack is well-constructed from quality materials. I've seen, handled, and used a lot of backpacks over the years, and I'd say that this one rivals the best in terms of quality. It may not be quite as good as an Osprey or Mystery Ranch, but it's a well-thought-out, well-made backpack.

What about comfort? This, I fear, is an area where my opinion doesn't mean much because comfort is such a subjective thing. I find the backpack reasonably comfortable: not the most comfortable, but never uncomfortable either. However, backpack comfort depends on so many things – from body size and shape to ailments and injuries – that your mileage can and will vary.

A smaller, lighter version – the Handsfree 1 – features a 268.8Wh/300W power station and a 42-liter backpack, offering a more modest amount of on-the-go power.

ZDNET's buying advice

To be honest, I approached this product review with a skeptical eye. After all, power stations are bulky and heavy, and I didn't see the Handsfree 2 approach being all that practical. However, the design of this power station and the quality of this backpack make the Handsfree 2 a workable system for anyone who needs to lug power to places where it's not practical to take a vehicle.

As a Bluetti unit, this is a quality power station constructed using quality components by a company with a track record of making exceptionally good equipment. The Bluetti Handsfree 2 is currently available for $399 from Amazon (use the $200 on-page coupon), while the Handsfree 1 is available from Bluetti for $299.

Which model should you opt for? That depends on how much power you need and how strong you're feeling.
