FOUR JACKERYS.
ONE BIG IDEA.
Why my portable power collection is just as useful around the house as it is aboard Vanilla, my VW campervan.
By NIX · A personal look at the batteries, the watts and the freedom to take electricity almost anywhere.
Power is freedom. And I like options.
Anyone who knows me knows I have a weakness for useful technology. My drones, the MacBook Air, cameras, campervan equipment and all the little gadgets that accompany modern life have one thing in common: at some point they need electricity. I could simply hunt for another mains socket. Or I could take the socket with me.
That was the attraction of the Jackery idea. What started as portable power for travelling has become something broader: a collection of four different tools, each with its own job. The small ones are brilliant for keeping my digital life alive. The large ones unlock proper household mains appliances away from the grid.
And I no longer think of them as 'camping equipment'. They are useful batteries for real life — at home, in the garden, out with my cameras, parked up for the night or halfway through a longer adventure in Vanilla.
“The clever bit isn't owning one massive battery. It's having the right amount of power, in the right place, for the right job.”
The four are the Explorer 300D, Explorer 240, Explorer 1000 and Explorer 2000. The exact product photographs in this feature are my reference images, with their plain backgrounds removed and a little NIX energy added.
Explorer 300D
My neat little digital workhorse
There is something particularly satisfying about a power station that knows exactly what it is for. The Explorer 300D is the odd one out in this collection, and that is actually its great advantage. It is compact, upright, easy to put somewhere sensible and particularly good at dealing with my collection of USB-powered technology. It is not a miniature version of the big Jackery with a normal mains socket. It is a dedicated DC and USB power source. That distinction matters.
In practice, this is the one I would reach for when I am working with cameras, charging drone accessories through their correct USB chargers, topping up my iPhone, running suitable USB-C kit or working away from a wall socket. It is ideal for a desk, picnic table, festival pitch or a quick stop with Vanilla. My MacBook Air is another obvious candidate, subject to its USB-C charging requirements and the available port wattage.
What I particularly like is the lack of fuss. When the job is mainly USB charging, converting battery power into mains AC and back again through an adapter can be an unnecessary detour. Direct USB-C can make much more sense. That does not mean every device will run at its maximum charging rate, but the 300D gives me a practical collection of high-output ports in a remarkably portable shape.
It earns a place at home too. If I am editing photographs on the sofa, keeping phones and tablets charged during a power cut, or sitting somewhere the nearest socket is inconvenient, it provides a clean, independent reserve. I would not ask it to boil a kettle. In fact, it has no mains outlet for a kettle to plug into. And that is precisely the point.
Best for: phones, MacBook USB-C charging, photography, drone charging accessories and low-voltage equipment.
Explorer 240
The little box with a proper socket
My Explorer 240 fills a different niche. Sometimes I want more than USB power but I do not want to carry one of the larger units around just to run a modest mains appliance. This is where the 240 earns its keep: it gives me a familiar UK socket as well as USB and 12-volt options.
Around the house it is useful for a small light, a compact device with a mains adapter, a modest low-wattage fan or charging electronics where USB alone is not the right answer. It is not a house-wide backup system and its 300-watt inverter has a clear ceiling. A large kettle, hairdryer, electric heater or air fryer is simply the wrong job for it. A low-power appliance, on the other hand, can feel effortless.
For Vanilla, it is the ideal sort of thing to keep accessible for an overnight stop: the power station I can pick up one-handed, move into the awning or set next to my seat, without disturbing the main leisure battery installation. It also makes sense when I am sat outside the van with a laptop, a light and a cup of coffee already made.
The lesson from using smaller batteries is that convenience often wins over sheer capacity. A big unit that stays in a cupboard is no use if the little one could do the job safely right now. I like having this as the bridge between USB-only gear and the serious mains power supplied by the bigger Jackery units.
Best for: modest mains loads, phone and laptop charging, portable lighting, short outings and light-duty backup.
Explorer 1000
The one that fits everyday life
If I had to explain why portable power stations are so useful to somebody who has never owned one, I would probably start with the Explorer 1000. It is big enough to be properly useful and manageable enough to carry into the house or out to Vanilla without turning the move into an expedition.
At home, the appeal is straightforward. I can keep communications and lighting available when mains electricity disappears; I can charge my MacBook, iPhone, cameras and the smaller devices I use every day; and I can run selected equipment for a meaningful period. A router drawing around 12 watts is a very different proposition from a 1,000-watt cooking appliance. The former can potentially run for days, whereas the latter will eat a sizeable battery very quickly.
I also appreciate how this unit complements the campervan rather than replacing its permanent installation. Vanilla already has a proper leisure electrical system: a Fogstar Drift lithium battery, Victron monitoring, an Orion DC-DC charger and solar charging. That system is for the van's own 12-volt services. The Jackery 1000 is portable AC muscle I can deploy for a separate job without casually mixing the two systems together.
And for cooking? The 1,500-watt continuous output is useful, provided the exact appliance rating and start-up demand remain within the Jackery's limits. That can cover plenty of smaller domestic gadgets, though a high-wattage induction hob or full-power air fryer may not be suitable. I always read the rating plate first.
This is the one I picture doing the unglamorous but important jobs: keeping a Wi-Fi router alive, charging several gadgets after a day out, lighting a room during an outage and generally taking the inconvenience out of life off-grid.
Best for: everyday home resilience, charging stations, selected cooking equipment, camping and longer evenings off-grid.
Explorer 2000
My portable powerhouse
The Explorer 2000 is where the collection steps up a level. When I want enough stored energy to make a proper difference, or I need to run an appliance with a more demanding mains rating, this is the Jackery I reach for. It is the heavyweight of my four-unit collection, and there is no pretending that makes it a pocket accessory. But the trade-off is worthwhile.
In Vanilla, this is the natural choice for the bigger electrical jobs. Rather than relying on the leisure battery to supply heavy inverter loads, I can keep the high-power work in a separate portable unit. An induction cooker, compatible air fryer or occasional mains appliance becomes a realistic prospect if its actual draw and surge remain within the Explorer's limits. I still watch the watts: a 2,000-watt appliance will empty even a large battery rapidly.
This is also the Jackery with the strongest case for coming back into the house. During a power interruption, I can use it as a temporary standalone source for selected appliances — for example lighting, mobile devices, my networking equipment and, if the numbers stack up, a fridge-freezer. It is not an excuse to backfeed the house through a wall socket. It is a portable source that individual appliances plug directly into.
Its most interesting attribute is flexibility. A battery that lives permanently in a campervan only helps when I am in the campervan. A portable station can follow me to the garden, the garage, a family gathering, a temporary outdoor workstation or a weekend away. That makes this more than camping gear. It is a small, movable energy asset, and I get quite a lot of satisfaction from having one available.
The Explorer 2000 also changes the way I think about power usage. Instead of asking only 'Can it run?', I ask 'How many watts, for how long, and what else might I need the remaining charge for?' That is the difference between buying a big battery and learning to use one intelligently.
Best for: the more demanding mains appliances, longer off-grid sessions, temporary home backup and flexible portable energy.

Why they belong in my house
01 / Keeping connected
My first priority in a home power cut isn't boiling the kettle — it is being able to see what I am doing, charge the phone, keep a light on and potentially keep the broadband router running if the wider network is available. A Jackery makes a surprisingly elegant temporary solution.
02 / A desk without a wall socket
Editing photographs on my MacBook Air, sorting drone footage or using my kit in a different room is easier when charging is not dictated by furniture and extension leads. The 300D is particularly well suited to compatible USB-C devices.
03 / Garage, garden and outdoor jobs
Portable lighting, a small device charger or a low-power piece of equipment can be far more convenient with a self-contained battery nearby. I still protect the Jackery from rain, damp and blocked ventilation — portable does not mean weatherproof.
04 / A little bit of resilience
Having a charged reserve is reassuring. A fridge-freezer, low-power fan, lighting or communication device can be selected according to the appliance rating and available watt-hours. I would never treat a portable Jackery as a whole-house wiring substitute.
The Jackery collection meets Vanilla
Vanilla is more than a Transporter with a bed in it. My VW T6.1 is a properly developed little travelling system, complete with a Fogstar Drift 105 Ah LiFePO₄ leisure battery, Victron SmartShunt, Orion 30 A DC-DC charging and a 200 W solar panel managed by Victron equipment. That gives me a permanent 12-volt foundation for the van's normal services.
The Jackery collection brings something different. I can run a separate portable appliance without taking a large load directly from the leisure battery, or bring a charged power station into the van for a few days away. The 300D can look after USB and camera equipment. The 240 is a handy little AC reserve. The 1000 tackles plenty of common jobs. And the 2000 is my bigger cooking and backup resource.
In theory, having solar, alternator charging, a lithium leisure battery and portable power stations gives me several distinct ways to manage energy. In practice, I am careful not to casually cross-connect them. My Sargent mains charger is isolated because it is not configured for my lithium installation. If I use a Jackery to supply a charger, it is through a correctly configured and suitable charger with the necessary protection, not by improvising a backfeed into the van.
What I would actually do on a three-night stop
During the day: Let the dedicated Victron system look after Vanilla's normal 12-volt load and harvest whatever solar is available. Use the smaller Jackery when I am out photographing or recharging portable gadgets.
At mealtimes: Put the larger Jackery to work on a compatible electric cooking appliance and check its real-time output, making sure I am not spending the whole night's energy on one meal.
After dark: Run the fridge and Webasto from the appropriately installed leisure system, keep the bigger portable reserves available and use USB charging rather than unnecessarily leaving an AC inverter active.
For those cold pub-stop evenings, the big advantage isn't that I can suddenly run an electric heater all night. A resistive space heater can flatten a battery very quickly. The advantage is that my lights, fridge, diesel heater, phones and cooking can each be handled by the setup best suited to the job.
Let's talk about real watt-hours
People naturally focus on the wattage printed on a power station, but there are two separate numbers. Watts (W) tell me how much power an appliance is demanding right now. Watt-hours (Wh) tell me roughly how much energy the battery can store. A 2,200-watt inverter does not mean the Explorer 2000 can deliver 2,200 watts for two hours.
These are illustrative estimates assuming 80% of rated battery energy reaches the load. Actual runtimes vary with inverter self-consumption, load, temperature, battery state, efficiency and appliance cycling; low-load AC runtimes can be especially different from this simple estimate.
I also have to resist the temptation to count battery capacity as if it were unlimited. My four Jackery units add up to 3,656 Wh nominally. Add the Fogstar's roughly 1,344 Wh (105 Ah × 12.8 V) and the headline figure is about 5,000 Wh — 5 kWh. But that is not one giant battery with one common output socket. It is five physically separate stores, each with distinct voltage, outputs, efficiencies, protection and charging arrangements. That separation is part of what makes the setup flexible.
Five kilowatt-hours of nominal stored energy is wonderful to have available. Managing it sensibly is what makes it useful.
The rules I don't bend
Never backfeed a house or campervan. I don't connect a Jackery to a wall socket or improvised inlet to energise building wiring. Proper transfer equipment and electrical design are essential for any integrated installation.
Never defeat electrical protection. RCD/earthing behaviour for portable power stations varies by model and load configuration. I don't assume a domestic-style extension or campsite hookup arrangement is safe without confirming the manufacturer's instructions and the actual protective arrangement.
Keep the numbers honest. I check the appliance's running watts and start-up surge, and stay within the model's rated output. High-powered heaters and cooking appliances can drain capacity quickly.
Respect the environment. I avoid rain, enclosed compartments, overheating, blocked vents, damaged cables and charging outside the specified temperature limits. These are proper electrical devices, not indestructible orange suitcases.
Keep charging systems compatible. I use the correct solar or charger input voltage, plugs and ratings. The van's existing lithium system stays electrically distinct unless a properly engineered charging path is used.
Not four versions of the same thing. Four different freedoms.
I can see why somebody might look at four power stations and ask if I have got carried away. Possibly. I have certainly never been accused of having too few charging options.
But genuinely, each Jackery has its own personality. The 300D is the neat digital specialist. The 240 is the easy little grab-and-go mains supply. The 1000 is the thoroughly useful all-rounder. And the 2000 gives me the capacity and output to take more of ordinary life beyond the mains socket.
What I love most is that their usefulness doesn't stop when I park Vanilla back on the drive. I can carry them indoors, use them around the house, keep them ready for an interruption to the power supply and bring them out for all sorts of little jobs I might otherwise never have considered.
That's where I think portable power is heading. Not just camping. Not just emergency backup. Not just an expensive battery for a weekend away. A way of making energy a little more mobile, more resilient and more personal.
And when Vanilla heads off on another adventure, the whole little power fleet is ready to travel.
