Most van life power guides involve permanent 12V wiring, a £2,000 lithium leisure battery, and a weekend with a crimping tool. There is a simpler route. A portable power station paired with a foldable solar panel covers the same loads for a fraction of the cost, with zero permanent modifications to the van.

What You Actually Need in a Van Power Kit
Whether you are converting a panel van or hiring a camper for a month in Portugal, your off-grid power setup comes down to four things:
- Power station: battery, inverter, and charger in one box. This is your overnight electricity.
- Solar panel: a foldable panel you angle toward the sun at camp. This recharges the station during the day.
- Cables: MC4 to XT60 solar cable (usually included) plus a 12V car charging cable for grey days.
- Load management: knowing what you can run. A compressor fridge draws 30-45W. A travel kettle draws 1,000W. Plan accordingly.
Quick Comparison
| Product | Capacity | Output | Weight | Charge Time | Price | Best For |
|---|---|---|---|---|---|---|
| EcoFlow RIVER 2 | 256Wh | 300W | 3.5kg | 60 min (AC) | £209 | Weekend trips |
| EcoFlow RIVER 2 Max | 512Wh | 500W | 6.1kg | 60 min (AC) | £319 | Most van lifers |
| Bluetti AC70 | 768Wh | 1,000W | 10.2kg | 45 min to 80% | £449 | Extended trips, couples |
| EcoFlow 220W Bifacial | 220W output | N/A | 9.5kg | N/A | £449 | Solar recharging |
All three power stations use LiFePO4 batteries rated for 3,000+ cycles, roughly ten years of daily use.
Power Stations: Which Size Fits Your Trip
EcoFlow RIVER 2: the weekend option
At 256Wh and 3.5kg, the RIVER 2 is the smallest station worth considering for van life. It charges phones, runs LED lights, and keeps a laptop topped up over a two-night trip. The 300W inverter handles most small electronics, and X-Boost mode pushes it to 600W for brief loads.
Charge from a wall socket in 60 minutes flat. That speed means you can top up at a service station coffee stop without waiting around.
The drawback: 256Wh will not keep a compressor fridge running overnight. For anything beyond a weekend, you will be chasing mains hookups. See our full portable power station guide for more options in this range.
EcoFlow RIVER 2 Max: the sweet spot
The RIVER 2 Max doubles capacity to 512Wh while keeping weight at 6.1kg. That is enough to run a 40W compressor fridge for roughly 10 hours, charge two phones, power a laptop, and still have headroom for LED lights. The 500W inverter (1,000W with X-Boost) covers a blender or travel hair dryer in short bursts.
For most solo travellers or couples on week-long summer trips, this is the right size. Solar input tops out at 220W, pairing perfectly with the panel below.
The drawback: you still cannot boil a standard UK kettle (3,000W). A gas hob solves that for about £15.
Bluetti AC70: for longer trips and heavier loads
At 768Wh and 1,000W continuous output (2,000W with Power Lifting mode), the AC70 is the most capable unit here. It runs a compressor fridge around the clock, charges laptops, and handles a small microwave in short bursts. The 500W MPPT solar input is the fastest in this group, and 950W turbo charging gets you from flat to 80% in 45 minutes on mains.
If you travel as a couple with higher power needs, or camp for weeks rather than days, this is the unit to consider. For more in this price range, see our best power stations under £500 guide.
The drawbacks: 10.2kg is manageable but not light. Only two AC outlets means power strips become essential. Under sustained loads above 800W, the battery gauge can read optimistically, so keep a margin before shutdown.
Solar Charging: EcoFlow 220W Bifacial Panel
A power station without solar is just a battery you need to plug in. The EcoFlow 220W Bifacial earns its place in this kit because the rear panel captures reflected light from the ground, adding up to 25% extra yield on concrete, sand, or snow.
The specs that matter for van life:
- 220W front side, 155W rear side (bifacial design)
- 9.5kg total weight, IP68 waterproof
- Monocrystalline cells with tempered glass rated to 148°C
- In UK summer sun (4-5 peak hours), expect 600-800Wh per day from the front panel alone
That output is enough to recharge a RIVER 2 Max from flat or get the AC70 to roughly 80%. For more panel options, see our portable solar panel guide.
The drawback: at £449 and 9.5kg, this is neither light nor cheap. If budget matters more than bifacial output, single-sided 220W panels start around £100 less but lose that rear-panel bonus entirely.
Total Kit Costs
| Kit Level | Power Station | Solar Panel | Total | Best For |
|---|---|---|---|---|
| Budget | EcoFlow RIVER 2 (£209) | None | £209 | Weekend trips, hookup sites |
| Mid-Range | EcoFlow RIVER 2 Max (£319) | EcoFlow 220W Bifacial (£449) | £768 | Week-long trips, wild camping |
| Full Power | Bluetti AC70 (£449) | EcoFlow 220W Bifacial (£449) | £898 | Extended trips, couples, higher loads |
Pro Tip: Calculate your daily power budget before buying. List every device, its wattage, and how many hours you run it. Multiply watts by hours for Wh. A 40W fridge running 10 hours is 400Wh. A phone charge is roughly 15Wh. Most van lifers use 300-600Wh per day, which puts the RIVER 2 Max squarely in the sweet spot.
The Verdict
Best all-round kit: EcoFlow RIVER 2 Max + 220W Bifacial panel (£768). Covers the daily loads of most solo travellers and couples without being too heavy to shift around the van.
Best for power users: Bluetti AC70 + 220W Bifacial panel (£898). Budget for the extra weight and buy a power strip.
Who should skip both: anyone staying exclusively on caravan parks with full mains hookup. You already have power. Spend the money on a better mattress instead.
Frequently Asked Questions
Can a portable power station run a van fridge all night?
Yes, with the right capacity. The RIVER 2 Max (512Wh) runs a typical 40W compressor fridge for about 10 hours. The AC70 (768Wh) manages closer to 16 hours.
How long does a solar panel take to recharge a power station?
In UK summer sun (4-5 peak hours), the 220W Bifacial recharges a RIVER 2 Max from flat in roughly 3-4 hours. Overcast days drop output to 30-50% of rated capacity.
Do you need a permanent 12V system for van life?
Not for most setups. Portable power stations handle the same loads without wiring, drilling, or voiding your van warranty. A permanent system only makes sense for full-time, year-round van life with daily loads above 1,000Wh.
What about charging while driving?
Most power stations include a 12V car charger cable. Charging from a cigarette lighter socket is slow (typically 80-100W), so a full recharge takes 3-5 hours of driving. It works as a top-up, not a primary source.
Is the bifacial solar panel worth the extra cost over a single-sided panel?
On reflective surfaces (concrete, sand, snow), the rear panel adds 15-25% extra output. On grass or dark ground, the bonus is minimal. If you camp regularly on hard standings or beaches, yes. On grass every time, a cheaper single-sided panel offers better value.
