VTOMAN FlashSpeed Pro 3600 review: A power station big enough for a motorcycle and small enough for a GoPro
Portable power stations have gotten impressively capable over the last few years, but every now and then you run into one that genuinely changes your sense of scale. That’s the feeling I had while testing the VTOMAN FlashSpeed Pro 3600, a 3.1 kWh, 3.6 kW monster of a power box that – despite weighing as much as a medium-sized meteor – rolls around surprisingly easily thanks to its integrated handle and wheels. And at its current price of $1,399, it’s one of the better deals I’ve seen in the high-capacity power station space.
I’ve tested plenty of power stations, but this one gave me a chance to really push the limits. Not just by plugging in the usual household devices, but by powering an actual electric motorcycle and even one of my electric tractors. And of course, after running big tasks, I also used it to enhance the little things – phones, cameras, drones – proving that even though the FlashSpeed Pro 3600 is built like a tank, it’s still great for the smaller, day-to-day tasks too.
Running my LiveWire Del Mar
One of the biggest tests I put it through was charging my LiveWire Del Mar electric motorcycle. That’s not something most smaller portable power stations can even pretend to do, but with 3,600 watts of AC output and a LiFePO4 battery pack big enough to shame some city cars, the VTOMAN didn’t blink to Level 1 charge me up.
I plugged the Del Mar into it using the bike’s onboard AC charger and a travel plug, and it actually worked – not blazing fast, but at the same speed I’d get from the wall, or roughly 1.5 kW of power. Of course, that drained the battery in under two hours, but it was enough to get nearly a third of a full recharge into my bike, which could be helpful in a pinch. That might not me a standard use case, but it was a fairly large power draw and something that often trips other power stations I test, so it shows that the VTOMAN can deliver.

The inverter even seemed to handle the load easily, staying cool and stable the entire time. This is the kind of capability that’s genuinely valuable: take it camping, trackside, or to a remote job site, and you actually have a real source of vehicle-level charging, not just a glorified phone bank.
Powering my NESHER L1400 electric tractor
If that wasn’t enough, I also put it to work on something even more unusual: my NESHER L1400 electric articulating loader. This is an honest-to-goodness electric tractor that I use frequently for work, so plugging it into a “portable” power station almost felt ridiculous.
And yet… it charged it up just fine. Again, we’re talking about a small portion of the battery, since the tractor has around 50% more capacity than even my motorcycle. But since this is very much an “in the field” vehicle, it’s not inconceivable that you might try pushing it too deep into the red zone to try and finish a job, potentially requiring a power station like this to put another 20% or so into the battery, or enough to let you drive back home for a full recharge at the barn or shop.
Just like with the motorcycle, the tractor charged through its onboard AC charger, and the VTOMAN delivered a steady, reliable stream of power. This opens some real possibilities for contractors or landowners who need remote, silent, mobile power for big tools or electric equipment.
The little stuff matters too
Once I finished doing the big-boy tests, I went back to more normal use cases. I charged my phone, GoPro, camera batteries, and even ran a 1,500W electric kettle just to see how the inverter spike handling worked. VTOMAN claims up to 6,000 watts of surge, and it handled appliance startup loads exactly as advertised.
I also charged a drone battery, powered a small air compressor to top up fat-tire e-bikes, and ran a laptop and external monitor setup for a few hours outdoors. The built-in USB-C 100W ports are fantastic – enough to fast charge modern laptops without needing a power brick.
Basically, if it plugs in, this thing will run it.
Charging the power station
Charging the 3,096 Wh pack from a wall outlet is surprisingly quick. VTOMAN claims a sub-two-hour full recharge, and my experience lined up pretty closely with that. It pulls serious wattage, so you’ll want to plug it into a proper circuit, but the speed means you can actually refill it between jobs or overnight without waiting forever.
I like that it doesn’t require its own charging brick, but rather just a standard AC cable, which it can conveniently store in the little storage compartment under the top lid. I recommend using that cable and not any random cable you have lying around, since the included cable uses thick enough gauge wiring to support the heavy charging current.
The LiFePO4 battery chemistry is another big plus. It’s long-lasting, thermally stable, and should give you many years of use. With over 3,000 cycles before it starts losing noticeable capacity, this is the kind of unit you can keep for a decade if you treat it well.
The display could be better outdoors
If I had to nitpick – and I always do – the screen is the weakest part of the experience. Indoors it’s fine, but outdoors in bright sunlight, it suffers from low contrast and visibility issues. I found myself shading it with my hand to check remaining time, input/output wattage, and the AC/DC toggles.
The data it provides is good. The readability in bright light is not. A slightly brighter or higher-contrast display would make a big difference for real-world, construction-site, or camping use.

Heavy… but thoughtfully so
At roughly 38 kg (over 80 pounds), this is not a light device. Lifting it is a two-hand operation unless you’re built like a forklift. But thankfully, VTOMAN clearly understands this: the integrated roller wheels and suitcase-style extending handle make it shockingly easy to move around.
It’s not something you’re tossing into the back of a hatchback on a whim, but if you roll it from garage to driveway, or around a campsite, it’s manageable.
Price: legitimately impressive
What surprised me most, though, is the price. For a power station with this much capacity, this much output, and LiFePO4 cells, it’s significantly cheaper than equivalent units from EcoFlow, Bluetti, or Jackery.
It may just be the current crazy-good holiday sales, but at $1,399, this is a killer deal. It’s one of the best cost-per-watt-hour values I’ve seen lately, especially considering the high-output inverter and fast-charging ability.
Final thoughts
The VTOMAN FlashSpeed Pro 3600 feels like one of the more capable, affordable large-format power stations I’ve tested. It’s powerful enough to charge a motorcycle and an electric tractor, yet refined enough to keep your laptop and camera gear going for days. And with the telescoping handles and built-in wheels, it’s easy to move around on both concrete floors and gravel driveways. Ask me how I know…
The downsides are still present though, including the hard-to-read outdoor display and its very substantial weight. But they feel minor compared to what you get for the money. If you’re looking for a serious, long-lasting, do-everything power station, this is absolutely one to look at.
