The Best Solar Lanterns for Eco-Friendly Camp Lighting
· Updated
The best solar lantern for camping is a light, packable one that charges free in daylight, throws 75 to 100 lumens of warm ambient light around your tent, and holds a waterproof rating that shrugs off a rain shower. For most trips that means an inflatable model like the MPOWERD Luci, or a rigid LED lantern with a USB backup that doubles as a phone top-up. No batteries to buy, none to bin, and nothing to plug in when you pitch up.
Solar lighting is the low-effort, low-waste way to light a camp. You leave the lantern in the sun during the day and it pays you back after dark. It is the quiet middle ground between disposable-battery lanterns and a full off-grid setup, and it suits anyone who wants less kit and less faff.
This guide sits alongside our wider advice on electric hook-up and powering your camp, and it is brought to you by Camping Sites in Britain, where you can find and compare campsites, caravan parks and glamping across the UK.
Why solar lanterns are worth it
Solar lanterns earn their place because the running cost is zero and the waste is close to it. There are no AA cells to keep buying, none to leak in the bottom of a drawer, and nothing heading to landfill. The sun does the charging, so a lantern you top up on the windowsill costs nothing to run all summer.
They are also brilliantly practical for camping. Most inflatable models pack down to the depth of a beer mat, weigh next to nothing, and clip to the outside of a rucksack. Rigid LED lanterns are heavier but earn it by storing more power and charging your phone. Either way you get dependable light without running a battery flat or trailing a cable across the pitch.
The main types, with real examples
There are four kinds worth knowing, and the right one depends on whether you want ambient tent light, a task light, awning decoration or an emergency backup.
Inflatable and collapsible solar lanterns
These are the classic camp lantern and the easiest to live with. The MPOWERD Luci started the category: a clear plastic disc with a solar panel on top and LEDs inside that inflates into a globe of soft light, packs flat when deflated, is waterproof enough to float, and clips shut for carrying. LuminAID makes a similar inflatable range, some with a built-in USB output. They give roughly 75 lumens of gentle ambient light, which is plenty for reading, cooking or finding your socks, and they weigh well under 200g.
Rigid LED solar lanterns with USB backup
Rigid lanterns are the workhorses. They hold a bigger internal battery, push out more light, often 100 to 300-plus lumens, and charge either from the sun or from a USB cable when the weather lets you down. Many double as a power bank with a USB output, so the same lump of kit lights the tent and tops up a phone. Goal Zero and Lighthouse-style models are the go-to here. They are heavier and slower to charge on solar alone, but the USB backup removes the main worry.
String and festoon solar lights
Solar string lights turn an awning or gazebo from functional to lovely in five minutes. A small panel pegged in a sunny spot charges a strip of warm LEDs that come on automatically at dusk, usually with a light sensor and a run time of six to eight hours. They are decoration rather than task lighting, but for the price and the zero running cost they are hard to beat for setting the evening mood.
Hybrid hand-crank and solar models
Hand-crank hybrids are the safety net. Alongside the solar panel they carry a wind-up dynamo, so even after three grey days you can crank a few minutes of light or a trickle of phone charge by hand. They tend to be chunkier and dimmer than dedicated camp lanterns, but as an emergency and power-cut light that never fully dies, they are reassuring to have in the boot.
What to look for
Match the lantern to the job, then check it survives a British field. These are the specs that actually matter.
| Spec | What to aim for | Why it matters |
|---|---|---|
| Brightness | 75 to 100 lumens ambient, 300+ for task light | 75 to 100 lumens lights a tent; you want more to cook or read a map by |
| Charge time | Solar 7 to 14 hours, USB 2 to 4 hours | Solar is slow, so a USB backup gets you a full charge fast |
| Run time | 6 hours or more on a full charge | Covers a full evening on the brightest useful setting |
| Waterproofing | IPX6 or better | Handles rain and dew; higher ratings survive a dunk |
| Weight and packed size | Under 200g and flat for inflatables | Keeps it in the rucksack, not the "leave at home" pile |
| Modes and dimmer | At least low, high and a dimmer | Low light stretches run time; dimming saves it for later |
| Phone charging | USB output on rigid models | One item lights camp and tops up a phone |
The IP rating is the one people skip. IPX4 copes with a shower, IPX6 with heavy rain, and IPX7 means it survives being dropped in water, which is why inflatables that float tend to carry it. In a wet British summer, aim for IPX6 as a minimum.
Practical UK tips for solar that actually charges
The honest truth about solar in Britain is that it charges slowly on a dull day, so you plan around the weather rather than trusting it. Charge the lantern fully before you leave: a couple of days on a sunny windowsill or the car dashboard gets it topped up while it is not doing anything else.
On site, hang it high and flat to the sky during the day rather than leaving it in the tent porch. A lantern clipped to the top of the awning or laid on the tent roof catches far more light than one sat in shade. Keep the panel clean, because dust and dried mud cut charging more than you would think.
Then treat the USB backup as your insurance. After three grey days even a good panel struggles, so a rigid lantern with a USB input, topped up from a power bank, is the difference between light and an early night. Our guide to how to use solar power while camping covers getting the most out of a panel, and the best portable solar panels pairs well if you want to keep several devices charged.
How solar compares with battery and rechargeable lanterns
Solar wins on running cost and waste, battery lanterns win on instant reliability, and USB-rechargeable lanterns sit in between. The right pick depends on how much you trust the forecast.
| Type | Running cost | Reliability | Best for |
|---|---|---|---|
| Solar | Zero after purchase | Weather-dependent | Summer trips, low-waste camping, light packing |
| Disposable battery | Ongoing, plus waste | Instant and consistent | Backup and cold or dark conditions |
| USB rechargeable | Low, needs a power source | Reliable if you can charge | Hook-up sites and power-bank users |
In practice a hybrid solar and USB lantern gives you the best of both. You charge it free when the sun is out and fall back on a cable when it is not. If you camp mostly on electric pitches, pair it with a proper power source; the best battery packs keeps a USB lantern going through a wet week without touching the hook-up.
Frequently asked questions
How many lumens do I need for a tent?
Around 75 to 100 lumens gives comfortable ambient light for a two to four person tent, enough to read, cook or move about. Step up to 300 lumens or more if you want a proper task light for maps, cards or setting up in the dark.
Do solar lanterns work on cloudy days in the UK?
Yes, but they charge much more slowly. On an overcast day a panel might take two or three times as long to fill. Charge fully before you travel and use a USB backup on dull runs of weather rather than relying on solar alone.
How long does a solar lantern take to charge?
Roughly 7 to 14 hours of direct sun for a full solar charge, depending on the model and the light. A USB top-up is far quicker, usually two to four hours, which is why a lantern with both is the safest choice for British trips.
Can a solar lantern charge my phone?
Many rigid LED lanterns can, through a USB output that lets them work as a small power bank. Inflatable models mostly cannot, though some LuminAID versions include a USB port. Check for a USB-out socket if phone charging matters to you.
Are solar lanterns waterproof?
Most camping models are rain-resistant, and many inflatables are fully waterproof and float. Look for an IP rating of IPX6 or higher for confident use in wet weather, and IPX7 if you want one that survives being dropped in water.
How long do solar lanterns last?
A good lantern gives six or more hours of light per charge and lasts several seasons of use. The built-in battery slowly loses capacity over time, so buy a model with replaceable or well-rated cells if you want it to keep going for years.
The short version
Pick an inflatable lantern for light, packable ambient light, or a rigid LED model with USB backup if you want more brightness and a phone top-up. Charge it fully before you leave, hang it high to catch the day, and keep a cable handy for grey spells.
