Buyer's guide
Best Solar Generators & Portable Power Stations UK 2026
A 'solar generator' is really two things sold together: a portable power station (a large lithium battery with mains sockets, USB and 12V outputs) and a folding solar panel to recharge it. Buy well and you get silent, fume-free power for camping, caravanning, market stalls, garden offices and — increasingly — winter power cuts.
The hard part is sizing. Brands love a big watt-hour headline, but usable capacity, battery chemistry and how fast the unit recharges matter far more than the number on the box. Below we rank our picks by role, then explain how to choose the right size once so you're not buying twice.
The verdict
For most UK buyers a 1,000Wh LiFePO4 unit — the Jackery Explorer 1000 v2 or EcoFlow Delta 2 class — is the sweet spot: enough to run a fridge, laptop, lights and phones through a long weekend or a day-long outage, light enough to carry, and cheap enough to justify. Only go bigger if you specifically want whole-fridge-plus-freezer backup for a house.
Top pick: Jackery Explorer 1000 v2 / EcoFlow Delta 2 (1kWh class)
Our top picks by role
1kWh LiFePO4 unit (Jackery Explorer 1000 v2 / EcoFlow Delta 2)
£600–£900
The size that suits the most people: roughly a kilowatt-hour of long-life LiFePO4, a 1,000W+ mains output that runs most household kit, and fast recharging from mains or a 200W panel.
Pros
- LiFePO4 cells last 3,000+ cycles
- Runs a fridge, laptop and lights together
- Recharges in 1–2 hours from mains
Cons
- 10–13kg — portable but not pocketable
- Panels usually cost extra
300–500Wh compact (EcoFlow River 2 / Jackery Explorer 300)
£180–£350
Light enough to throw in the car for a festival or a couple of nights under canvas. Keeps phones, a drone, lights and a small cool box going without weighing you down.
Pros
- 3–5kg, genuinely portable
- Cheapest way into a good brand
- Fast USB-C for laptops
Cons
- Won't run high-wattage kettles or heaters
- Capacity gone quickly if you push it
2kWh+ expandable (EcoFlow Delta Pro / Bluetti AC200L)
£1,300–£2,500
When the goal is riding out a real power cut — fridge, freezer, broadband, a few lights and phone charging for hours — this is the class to look at. Many accept extra battery modules later.
Pros
- Runs fridge + freezer for many hours
- Expandable capacity
- High continuous output
Cons
- Heavy (20kg+)
- Overkill for camping
- Serious money
200W folding solar panel (add-on)
£250–£400
The panel is what turns a power station into a solar generator. A 200W folding panel realistically returns 400–800Wh on a good UK day — enough to keep a mid-size unit topped up off-grid.
Pros
- Folds flat, kickstand built in
- Works with most brands via adapters
- No fuel, no noise
Cons
- UK cloud cover cuts real output hard
- Bulky when carrying multiple
How to size a power station without overpaying
Work out the watts of the things you actually want to run at once, then multiply by the hours you need them. A 60W fridge cycling for 12 hours is roughly 350–450Wh; a 15W string of lights for an evening is trivial; a 2,000W kettle is a capacity-killer and the reason cheap units trip out.
As a rule of thumb: 300–500Wh covers phones, laptops, lights and a small cool box for a weekend. Around 1,000Wh comfortably adds a compact fridge and a short outage. Above 2,000Wh is home-backup territory. Buy for the job you'll do most weekends, not the once-a-year worst case.
Why battery chemistry (LiFePO4) matters more than the price
Two units with the same watt-hours can have wildly different lifespans. Older and cheaper power stations use NMC lithium cells rated for roughly 500 cycles; modern ones use LiFePO4 (also written LFP) rated for 3,000–4,000 cycles and far safer under abuse. Over years of weekly use that is the difference between a unit that fades in two summers and one that outlives the decade.
In 2026 we would not buy a new power station that isn't LiFePO4 unless it's a genuinely tiny sub-£150 travel unit. Every one of our picks above uses LiFePO4 where the brand offers it.
Solar generator vs whole-home battery — not the same thing
A portable power station is not a home battery like a Tesla Powerwall or GivEnergy system. Home batteries are fixed installations wired into your consumer unit and your rooftop solar, sized in the 5–15kWh range and fitted by an electrician. Portable units are plug-and-play, movable, and a fraction of the capacity.
If your goal is cutting your grid bill with rooftop solar, that's a fixed-battery, professional-installation question — a different product class entirely. Portable power stations are about flexible, movable power you can take to a tent or wheel to the fridge when the lights go out.
Who it's for
- Campers and caravanners who want quiet power without a petrol generator
- Anyone who wants a few hours of fridge-and-broadband insurance against a power cut
- Van-lifers, market traders and photographers working away from mains
- Not for whole-house, all-day backup — that's a fixed home-battery job
