Quick answer: for most allotments, a small portable power station of around 250 to 300Wh is all you need. That’s enough to charge cordless tool batteries, run a radio and lights, and keep your phone topped up. Charge it at home and take it back with you after each visit. Add a small solar panel if you spend whole days on the plot. Check your allotment rules before fixing anything to the shed or plot.
First: check your allotment rules
Every council and allotment association sets its own rules. Many require permission before you put up or change a shed or greenhouse, and fixed installations such as roof-mounted panels may need approval too. A portable power station that comes and goes with you avoids most of these questions, but it’s worth reading your tenancy agreement or asking your committee first.
What can you run on an allotment?
Allotment power is about small, useful loads, not heavy appliances.
| Kit | Will a small power station run it? |
|---|---|
| Phone and radio | Yes, easily |
| LED lights for winter evenings | Yes, for many hours |
| Cordless tool battery chargers | Usually. Check the charger’s wattage on its label |
| Small 12V water pump for water butts | Usually, via the 12V socket |
| Corded lawnmower or strimmer | Often not. Many draw 1,000W or more |
| Kettle | No. UK kettles draw 2,500 to 3,000W. Use a camping stove outdoors instead |
Our picks for allotments
Three small units suit allotment life. They’re all light enough to carry from the car, and all use long-life LiFePO4 batteries.
- EcoFlow RIVER 3: 245Wh, 300W (600W X-Boost), just 3.55kg, around £199. The lightest option.
- Bluetti Elite 30 V2: 288Wh, 600W continuous, 4.3kg, around £199 to £219. The most power for the money, and it takes up to 200W of solar.
- Jackery Explorer 300 Plus: 288Wh, 300W, 3.75kg, around £199. Simple and well made.
Prices are approximate UK prices (RRP or typical retailer price) when we checked in November 2026. They change often, so use the buttons to see today’s price.
If you want to run corded garden tools, you’ll need a bigger 1kWh unit with at least 1,800W of output. See our guide to the best portable power stations in the UK.
Do you need a solar panel?
Probably not at first. If you visit for a few hours at a time, charging the power station at home is simpler and cheaper. A panel makes sense if you:
- Spend whole days on the plot in spring and summer
- Want to run a small water pump for your water butts
- Leave lights on for evening work
A 100 to 160W portable panel is plenty for the small units above. In a UK summer, a 160W panel can add roughly 0.6 to 0.9kWh on a good day, more than enough to refill a 300Wh unit. In winter it will only give a small top-up. Our guide to the best portable solar panels in the UK compares the options.
Security: don’t leave it in the shed
Allotment sheds are easy targets for thieves, and a power station is exactly the sort of thing that goes missing. Take it home after each visit, and don’t leave solar panels out overnight unless they’re securely fixed with permission. Cold is another reason to bring it home: most lithium batteries shouldn’t be charged below freezing.
Safety tips
- Keep the power station dry. Use it inside the shed or under cover, never on wet ground.
- Don’t run a petrol generator inside the shed. Generators produce carbon monoxide, which can build up quickly in small spaces. See our guide to power stations vs petrol generators.
- Use outdoor-rated leads for anything plugged in outside.
Frequently asked questions
Can I have electricity on my allotment?
Most allotments don’t have mains electricity, and getting it connected is rarely practical. A portable power station is the easiest way to have power on the plot.
Can I put solar panels on my allotment shed?
Possibly, but check your tenancy agreement and ask your council or association first. Fixed installations often need permission. A portable panel you take home avoids this.
What size power station do I need for an allotment?
Around 250 to 300Wh suits most people. Go up to 1kWh if you want to run corded tools.
Can I charge cordless tool batteries on my allotment?
Usually, yes. Most tool chargers are well within the output of a small power station, but check the wattage on your charger’s label first.
