The best campervan power station combines strong solar input, a 12V output for your fridge, and alternator charging so it tops up while you drive. Our top pick is the EcoFlow Delta 3 Max Plus, with 1,000W alternator charging and 1,000W of solar across two inputs. For 2,073.6Wh rated for 6,000+ cycles, see the Bluetti Elite 200 V2. For a lighter 12kg unit with 12V car charging, look at the EcoFlow Delta 2. To rank these against every other pick, see our best portable power stations UK comparison.
EcoFlow Delta 3 Max Plus
It’s our top pick for van life. It supports 1,000W alternator charging, so it tops up while you drive. You also get 1,000W of solar across two inputs. A 12V car output and an Anderson 12V 30A output run your fridge and other 12V gear. Four UK sockets cover your mains devices, and 2,048Wh gives you real off-grid range. It’s heavy at 22.1kg, so this is one to leave installed rather than carry in and out. See the full review for full specs and details.
What Makes a Good Campervan Power Station?
Van life power needs differ from casual camping. You likely want to run a 12V fridge for days, charge devices, and stay off-grid for longer. That makes solar input, a 12V output, and charging from your alternator while you drive the features that matter most. To work out the right capacity for your rig, use our power station sizing guide. A LiFePO4 battery suits the daily charging van life involves. Pass-through charging lets you power devices while the unit itself recharges.
Solar Input (W)
Higher MPPT solar input recharges you faster on touring days, which keeps you off-grid for longer.
12V Output
A 12V DC output runs a 12V compressor fridge and van accessories directly, more efficiently than through the AC sockets.
Alternator / DC Charging
Charging from your van's 12V socket or an alternator charger tops the unit up while you drive. That matters in the UK, where solar isn't always reliable.
Expandability
An expandable unit lets you add capacity for full-time van life or longer off-grid trips.

The Delta 2 suits campervan owners who want a proven unit with 12V and 24V car charging. It’s light enough to move between van and pitch, and it also suits camping and light home backup. It’s the previous-generation model, no longer sold new by EcoFlow UK, and PCWorld calls its 30ms switchover too slow for a desktop PC. For a faster switchover and more solar input, choose the Delta 3 Max Plus instead.
Also worth considering for campervans
These three suit specific set-ups better than our three main picks, from a lighter expandable unit to a fixed, high-capacity install.
| Model | Why consider it | The catch | Link |
|---|---|---|---|
| EcoFlow Delta 3 Plus | 800W alternator charging with EcoFlow's alternator charger, plus 1,000W of solar and expandable up to 5kWh | Fans can run even at low loads, according to T3 and Trusted Reviews | EcoFlow Delta 3 Plus review |
| Jackery Explorer 1000 v2 | At 10.8kg it's easy to move around; Jackery UK pitches it for caravan trips and T3 recommends it for caravanners and boaters | Only 400W of solar, and it isn't expandable | Jackery Explorer 1000 v2 review |
| Bluetti Apex 300 | Large 2,764.8Wh capacity, suits a fixed install in a van, boat or cabin | At 38kg it isn't portable, and both the USB and 12V outputs need the optional Hub D1 | Bluetti Apex 300 review |

Can a Power Station Replace a Leisure Battery?
For many van lifers, yes. A high-capacity power station paired with a solar panel can do much the same job as a traditional leisure battery, without the wiring.
The pros are real: it’s portable, so you can take it indoors to charge or lend it for other jobs. You don’t need a qualified installer. LiFePO4 batteries are rated for thousands of charge cycles, similar to or better than a wired leisure battery.
The cons matter too. A portable unit costs more upfront than a basic leisure battery. Its 12V output is limited, so it won’t run heavy 12V draws like a bow thruster. It’s not permanently wired in either, so if it needs charging, your whole 12V system goes down with it.
If you are weighing up the two options, our guide to the best power stations for camping and our solar charging guide cover the detail.
Frequently Asked Questions
For weekend trips with occasional hookup, around 1,000Wh is usually enough. For full-time van life with little hookup, aim for 2,000Wh or more. Use our sizing calculator with your devices for a precise figure.
Choose the Delta 3 Max Plus if you want more capacity, 1,000W alternator charging and dual solar input, and don’t mind 22.1kg. Choose the Delta 2 if you want a lighter 12kg unit that’s easier to move between your van and your home. It’s the previous generation, though, with a slower 30ms switchover.
Yes. Most units charge from the 12V car socket, and some support an alternator charger that tops up faster as you drive. This is useful in the UK where solar is not always reliable.
Yes. Most have a 12V DC output for 12V compressor fridges. A 40-litre fridge draws around 30 to 60W, so a 1,000Wh unit gives roughly 16 to 30 hours of fridge time.
Both work, and using both covers you best. Alternator charging doesn’t depend on the weather: the EcoFlow Delta 3 Max Plus takes up to 1,000W from an alternator charger while you drive. Solar keeps you topped up once you’ve parked up, but output depends on sunlight. So pair it with alternator or mains charging rather than relying on solar alone.
Most people simply secure it rather than hard-wire it. For permanent integration, consult an auto-electrician. The benefit of a portable unit is being able to remove it for indoor charging or other uses.
EcoFlow leads on alternator charging (1,000W on the Delta 3 Max Plus). Bluetti leads on solar input (2,400W on the Apex 300) and total expansion. Choose based on whether you charge mostly while driving or mostly from panels.
For full-time van life, aim for at least 2,000Wh of capacity. Go higher if you run a compressor fridge, laptop and other devices daily without regular hookup. Many full-timers choose an expandable unit like the EcoFlow Delta 3 Max Plus, so they can add extra batteries as their needs grow. Pair it with 400W or more of solar, and use our sizing calculator for a figure based on your own set-up.
No, a portable power station comes with a built-in inverter, so you don’t need to buy one separately. The inverter turns the battery’s stored DC power into standard AC power for your UK sockets. Most modern units produce a pure sine wave, which is safe for sensitive electronics like laptops and CPAP machines.
