Our Top Picks

8 Best Solar Chargers

1. BigBlue 28W Foldable Solar Charger

The BigBlue 28W is the solar charger that consistently earns its place at the top of lists like this one. Three ports (one USB-A and two USB-C) put out a combined 5V/4.8A, and SmartIC technology automatically detects what you’ve plugged in and delivers the optimal charging speed. In practice, that means your phone charges about as fast from this panel as it does from a wall socket, as long as there’s decent sunlight.

The N-Type solar cells are a meaningful upgrade over standard panels. Rated at 25.4% conversion efficiency, they pull noticeably more power from low-angle or partly cloudy skies, which matters a great deal in the UK. Folded up it’s roughly the size of a thick paperback (28 x 15.5 x 3cm) and opens out to 83.5cm wide with four steel hooks ready to clip onto a backpack strap or tent guy-line. If you’re doing any multi-day hiking or camping, this is the one to take.

It’s worth being clear about what this is, though: a solar panel, not a battery. It charges devices directly from sunlight. You’ll need either good weather or a power bank in the loop to charge anything in the shade. The IPX4 splash rating handles light rain and morning dew without complaint, but it won’t survive being submerged. Minor gripes, given the output quality.

At £68.99 with over 1,400 UK ratings behind it, the BigBlue 28W sits in the sweet spot between affordable and genuinely capable. It’s the one we’d recommend first to anyone planning a camping trip or festival.

Features

• 28W output, 3 ports (1 USB-A + 2 USB-C), 5V/4.8A combined
• N-Type solar cells, 25.4% conversion efficiency
• Folds to 28 x 15.5 x 3cm; opens to 83.5 x 28cm
• 4 steel hooks for backpack or tent attachment
• SmartIC auto-optimises charging speed per device
• IPX4 splash and weather resistant
• Compatible with smartphones, tablets, cameras and power banks

2. BLAVOR Solar Power Bank 20000mAh

If you want one device that does everything: charges six devices at once, includes built-in cables so you’re never hunting for a lead, and even charges an Apple Watch wirelessly. The BLAVOR is hard to argue with. The four built-in cables cover USB-C (x2), Lightning/iOS, and USB-A, and there are three additional ports, giving you simultaneous access to six connections total. It’s a genuinely impressive piece of kit for the price.

The 20000mAh battery provides around 4.2 full charges for an iPhone 15 or 2.7 for an iPad Mini 6. The 20W USB-C output makes top-ups reasonably quick too, and the built-in camping light and flashlight mean it doubles as a useful piece of outdoor gear on its own merits. The solar panel on the back won’t fully recharge the unit from sunlight alone, but it will extend your capacity meaningfully over a full day outdoors.

It’s on the heavier side given all the built-in features, and £59.99 puts it above the mid-range. But if your priority is carrying one versatile, well-equipped unit rather than panel plus separate bank, the BLAVOR earns its price.

Features

• 20000mAh capacity with 20W USB-C fast charging
• 4 built-in cables (2x USB-C, 1x iOS, 1x USB-A)
• Wireless charging pad for Apple Watch
• 3 additional output ports, charge up to 6 devices
• Built-in camping light and flashlight
• Solar panel for emergency top-up charging

3. FlexSolar 40W Foldable Solar Charger

The FlexSolar 40W is the one to get if you need to charge a laptop or small power station from solar. Its USB-C PD 2.0 port puts out up to 40W. That’s enough for most ultrabooks and the majority of compact power stations, while the USB-A QC3.0 port delivers 18W for phones and tablets. There’s also a DC output at 19V/2.1A for direct connection to compatible devices. Most solar chargers in this price range top out at 28W and skip the DC port entirely.

The ETFE coating gives it a 24% conversion efficiency rating, which is meaningfully better than standard PET-laminated panels. IP67 waterproofing means it can handle genuine rain rather than just splash. That’s a real advantage if you’re relying on it through variable UK weather. At 1,154 reviews and 4.2 stars it has a solid track record.

The trade-off is size and weight: 40W takes more panel surface area than 28W. It’s still foldable and packable, but it’s a bigger item to carry than the BigBlue. If you’re charging phones and tablets only, the extra wattage isn’t necessary. But for anyone wanting to top up a laptop or portable power station on the go, this is the right choice.

Features

• 40W output; USB-C PD2.0 40W, USB-A QC3.0 18W, DC 19V/2.1A
• ETFE coating, 24% conversion efficiency
• IP67 fully waterproof
• Compatible with phones, tablets, laptops and power stations
• Foldable and packable panel design

4. Hiluckey Solar Power Bank 20000mAh

With over 11,500 UK ratings, the Hiluckey is by far the most reviewed solar power bank on this list and that volume of feedback tends to filter out anything fundamentally flawed. It’s a 20000mAh wireless charging power bank with a solar panel on the back, four simultaneous charging ports, and a 3A USB-C fast charge output that can fully replenish a phone in around 1.3 hours.

The wireless charging pad is the standout feature. Press the power button, set your phone face-up on the centre of the unit, and it starts charging without any cable. It’s genuinely convenient in situations where you don’t want to root around for a lead at a festival, in a tent, or in a bag pocket. The solar panel on the back works as a slow emergency top-up in sunlight. Don’t expect it to replace a mains charge, but it extends the range over a long weekend outdoors.

The Hiluckey is heavier than a standard power bank of the same capacity, and the wireless charging won’t match the speed of the 3A wired port. But £36.99 for this feature set, backed by that many verified reviews, makes it the safest mid-range buy on this list.

Features

• 20000mAh capacity up to 8 phone charges
• Wireless charging pad (Qi compatible)
• 4 simultaneous output ports including 3A USB-C
• Charges fully via USB-C in approximately 7 hours
• Solar panel for emergency top-up in sunlight
• Built-in LED torch

5. Vikeri Solar Power Bank 26800mAh

The Vikeri offers the largest capacity on this list at 26800mAh, and at £30.38 it’s remarkable value for money. Four output ports let you charge multiple devices simultaneously, and the 55W fast-charging technology means you’re not waiting around when you do plug in. There’s also a built-in flashlight, which earns its place on any camping or emergency kit list.

The solar panel on the back will trickle-charge the unit in direct sunlight useful for extending range over several days outdoors but not a substitute for mains charging when you have access to it. Automatic current regulation prevents overvoltage and overheating, which is reassuring on a bank this size. It’s a no-frills product, but for sheer capacity at a low price it’s difficult to match.

Features

• 26800mAh capacity highest on this list
• 55W fast charging with 4 output ports
• Built-in flashlight
• Solar panel for emergency top-up
• Automatic current regulation and overvoltage protection

6. WOWMVP Solar Power Bank 10000mAh

Push the stake in, hook it to your bag, and go the WOWMVP is about as fuss-free as solar charging gets. It’s a compact 10000mAh bank with a PD15W USB-C port, two standard USB-A outputs, and a 10-LED torch with a carabiner hook built in. At £24.99 it’s the cheapest genuine solar power bank on this list, and its 4.8-star rating albeit from a smaller sample suggests people are happy with it.

The 10000mAh capacity gives you two to three full phone charges, which is plenty for a day trip or festival day. IPX4 weather resistance handles light rain without drama. It won’t suit anyone who needs to charge a laptop or run multiple devices for days on end, but as a lightweight companion for day hikes, beach trips, or keeping one device alive over a weekend, it does the job well at a price that’s easy to justify.

Features

• 10000mAh capacity, 2-3 full phone charges
• PD15W USB-C output; 2x USB-A outputs
• 10-LED torch with carabiner hook
• IPX4 weather resistant
• Solar panel for emergency top-up
• Compact and lightweight

7. ELECOM NESTOUT 28W Portable Solar Panel

The ELECOM NESTOUT is the most expensive panel on this list and makes no apologies for it. It won an IF Design Gold Award one of the most prestigious industrial design prizes in the world and uses SunPower MAXEON cells, which are among the most efficient silicon cells commercially available. The 4-panel fold-out design with adjustable stands is beautifully engineered, and the water-resistant ripstop nylon housing is built to take punishment that would ruin a cheaper panel.

Output is 28W through dual USB-A ports. It’s a premium specification for premium hardware. The SunPower cells deliver up to 24% efficiency and hold that performance better than standard cells as they age. If you’re spending serious time outdoors and want a solar panel that lasts for years rather than one camping season, the NESTOUT justifies its £124.99 price point. For occasional use, it’s overkill but for anyone who treats outdoor kit as a long-term investment, it’s genuinely outstanding.

Features

• 28W, dual USB-A ports
• SunPower MAXEON cells, up to 24% efficiency
• IF Design Gold Award winner
• Water-resistant ripstop nylon housing
• 4-panel fold-out design with adjustable stands
• Foldable and lightweight for travel

8. FlexSolar 6W USB Solar Panel

The FlexSolar 6W is not glamorous. It’s a small, flat monocrystalline panel with a single USB output and a price tag of £15.99. But with over 2,500 UK ratings and a 4.0-star average, it clearly works for a lot of people particularly those who just want to trickle-charge a phone or top up a power bank while it sits on a windowsill or garden chair.

At 6W and 5V it’s not fast. Charging a phone directly takes patience. But for powering low-draw devices like security cameras, bird box cameras, USB fans, and small garden sensors, or for very slow emergency charging, it does exactly what it says. The IP67 rating means it can sit outside in the rain without issue. At £15.99 it’s the most affordable entry point on this list, and for ultra-low-budget or niche use cases it earns its place.

Features

• 6W, 5V USB output
• Monocrystalline cells, 24% conversion efficiency
• IP67 fully waterproof and dustproof
• Compatible with phones, power banks, security cameras, USB fans
• Lightweight and compact

Solar Charger Buying Guide

Key Takeaways

• Solar chargers and solar power banks are different products: a solar charger converts sunlight directly into electricity to charge a connected device or power bank, whilst a solar power bank has an integrated battery that stores solar energy for later use
• Wattage determines charging speed: 5-10W suits phone and small device top-up charging, 20-40W handles tablets and faster phone charging, 60W+ is needed for laptops and power stations
• Monocrystalline panels are more efficient per square centimetre than polycrystalline, which matters for portable chargers where panel area is limited; look for monocrystalline specification for the best performance from a compact unit
• USB-C Power Delivery (PD) output is increasingly important as it is the standard for fast-charging modern phones and laptops; older USB-A only chargers cannot deliver fast charging to current devices
• Charging speed in UK conditions is typically 30-50% of the rated wattage on an overcast day; a 20W charger may produce only 6-10W in typical UK cloud cover, so choose a higher wattage than the minimum needed for your intended use
• Foldable solar charger panels suit camping and travel: they pack down small, fold out to a large panel area, and attach to backpacks and tents via integrated loops and carabiners
• IP ratings of IPX4 or higher are needed for outdoor use in UK conditions; chargers that are not water resistant will fail in rain, which is a serious limitation for camping use
• Direct device charging without a power bank works in full sun but is unreliable in partial cloud; using the solar charger to top up a power bank, which then charges the device, gives more consistent results

Solar Charger vs Solar Power Bank: Understanding the Difference

This distinction matters because the two products serve different purposes. A solar charger is a panel-only device. It converts sunlight into electricity in real time and passes that electricity to whatever is connected via USB. When the sun is shining, it charges your phone or power bank. When the sun goes behind a cloud, charging slows or stops. It has no internal energy storage.

A solar power bank combines a solar panel with a rechargeable battery. The solar panel charges the internal battery continuously during the day. When you connect your phone, it draws from the battery rather than directly from the panel. This means charging is consistent regardless of whether the sun is out at that exact moment. The trade-off is that the integrated solar panels on most solar power banks are very small, typically 0.5-2W, which means they charge the internal battery very slowly. A 10,000mAh solar power bank may take 30-50 hours of direct sun to charge fully via its solar panel alone; the power bank is primarily charged by USB from the mains, with solar providing a slow supplemental top-up.

For serious outdoor and camping use where you need to charge multiple devices over several days without mains access, a dedicated foldable solar charger paired with a conventional power bank is more practical than a solar power bank. You get a much larger panel area (higher wattage, faster charging), a more capable separate battery, and better performance in the variable sun conditions typical of UK camping.

Wattage and Charging Speed

The wattage rating of a solar charger tells you its maximum output in ideal full-sun conditions. In practice, UK conditions rarely produce full-sun output for extended periods, and the effective charging wattage is typically 40-70% of the rated figure on a clear day and 20-40% on a partly cloudy day.

For phone charging, 10W is a reasonable practical minimum in good UK summer conditions. A 10W charger producing 5-7W in average outdoor sun will fully charge a modern smartphone in 3-5 hours. In overcast conditions producing only 3-4W, the same charge may take 6-10 hours or more. If fast phone charging is the goal, a 20W charger that produces 10-14W in cloudy UK conditions is far more practical than a 10W charger that struggles to keep pace with normal phone use.

For tablets, aim for 20-40W rated output to achieve reasonable charging speed in UK conditions. Laptops typically require 45-65W for reliable charging; a solar charger rated below 60W may charge a laptop very slowly or not at all in typical UK cloud cover. For large power stations and camping batteries, 100W+ foldable panels are available and needed for timely charging of high-capacity batteries.

Panel Technology: Monocrystalline vs Polycrystalline

Monocrystalline silicon cells are more efficient than polycrystalline, meaning they produce more electricity per unit of panel area. For a portable solar charger where the folded size and weight matter, monocrystalline is the better choice. At the same panel area, a monocrystalline charger produces 15-22% more power than a polycrystalline equivalent.

Monocrystalline panels also perform relatively better in low-light and diffuse light conditions, which is relevant for UK use where full direct sun is less common than in southern Europe. In the scattered light of an overcast sky, monocrystalline cells maintain better efficiency than polycrystalline.

Almost all quality foldable solar chargers now use monocrystalline cells, and this should be specified in the product description. ETFE (ethylene tetrafluoroethylene) laminate on the cell surface is a further upgrade found on premium models: it is more durable, more transparent (allowing slightly more light to reach the cells), and lighter than standard PET plastic laminate. For a charger that will see hard camping use, ETFE lamination is worth the premium.

USB Output Standards: Ports and Protocols

The USB output specification determines what devices you can charge and how fast. Older USB-A outputs at 5V/2A provide 10W maximum, which is sufficient for older phones and basic device charging but cannot fast-charge modern smartphones. USB-C Power Delivery (PD) outputs at up to 20V/3A (60W) or higher are needed for fast-charging current iPhones, Android flagships, and USB-C laptops.

Check the specific USB-C PD wattage output of any charger you consider. A USB-C port that delivers only 5V/3A (15W) charges devices slowly even though it is a USB-C socket physically. A USB-C PD port rated at 20W or above genuinely fast-charges compatible phones. For laptop charging, 45W PD minimum is needed for most ultrabooks; 65W or above handles larger laptops.

Multiple USB ports allow simultaneous charging of several devices. Some chargers include intelligent power management that distributes the available wattage between connected devices based on their requirements, which prevents a high-demand device starving a lower-priority device of power. This is useful when charging a phone and a power bank at the same time.

Foldable Design for Camping and Outdoor Use

Foldable solar chargers fold down to a compact rectangle roughly the size of a book and unfold to a large panel area. They typically include integrated attachment loops or grommets so the charger can be attached to a backpack, tent, or pitched on a rock surface using the included stand.

The number of panels in the foldable design affects both the packed size and the output. A 10W charger might use two panels that fold together. A 40W charger might use four panels. The more panels, the larger the folded size. For backpacking where pack weight and volume is critical, a 10-20W foldable charger is the practical maximum. For car camping, festival camping, or basecamp use where weight matters less, a 40-80W foldable panel is feasible.

The quality of the folding joints and panel connections is a long-term reliability concern. Cheap foldable chargers develop loose connections at the fold points after repeated opening and closing cycles, causing intermittent output. Quality models use reinforced seam stitching and robust cable connections. Reading reviews for mention of durability after 6-12 months of use is a useful check before buying.

Weatherproofing for UK Outdoor Use

A solar charger without water resistance is a liability for UK outdoor use. UK weather is unpredictable: clear mornings that turn to rain by afternoon are the norm rather than the exception from September through May. A charger rated IPX4 (splash resistant from any direction) handles light rain, morning dew, and the splashing of outdoor use without failing. IPX5 and above handles heavier rain exposure.

Many cheap solar chargers have no water resistance rating. Using them in any wet conditions risks short-circuiting the USB ports or damaging the panel connections. For any charger intended for camping, hiking, or garden use in the UK, an explicit IPX4 or higher rating is a practical necessity rather than a nice extra.

Note that water resistance usually applies to the panel itself: the USB ports and charge controller may have separate protection levels. Covers over the USB ports prevent moisture entering the charging socket when not in use, which is worth checking for on any charger that will be used in wet UK conditions.

UK Use Cases: Camping, Hiking, Garden, and Emergency

For camping in the UK, a 20-40W foldable monocrystalline charger with USB-C PD output and IPX4 weather resistance is the most practical specification. Attach it to the tent or awning during the day, connect a conventional power bank to charge slowly throughout the day, and use the power bank to charge phones and devices in the evening when the panel is packed away. This approach separates panel charging from device charging and works reliably even in variable UK weather.

For hiking and backpacking, weight is the constraint. A 10-15W foldable charger weighing 200-400g that clips to the back of a rucksack trickle-charges a power bank during the walk. On a clear summer day, this can add 30-50% charge to a 10,000mAh power bank over a long day’s walk. In overcast conditions, the same panel might add only 10-20%. Set expectations accordingly: a hiking solar charger supplements your power bank rather than replacing mains charging.

For garden use, a 10-20W charger positioned on a south-facing garden table in summer is a convenient way to top up phones, headphones, and small devices whilst working outdoors. It is not designed to charge garden power tools or high-capacity batteries, but handles personal device charging reliably in good UK summer conditions.

For emergency preparedness, a 20W foldable charger stored with a high-capacity power bank ensures phone charging capability during a power cut regardless of duration. The combination of solar charging during the day and power bank storage for device use at any time gives genuine off-grid communication capability.

Case Study: Keeping Connected on a Week-Long Highland Trek

Background

A keen hillwalker from the East Midlands planned a seven-day wild camping route through the Scottish Highlands, covering roughly 120 kilometres with no access to mains electricity throughout. His key device needs were a smartphone for navigation and photography, a GPS tracker, and a head torch with a USB charging port. He wanted to keep all three alive for the full week without carrying excessive weight.

Project Overview

After researching his options, he opted for a combination approach: a BigBlue 28W foldable panel clipped to the back of his rucksack, paired with a 20000mAh solar power bank for overnight storage. The panel would charge the power bank throughout each walking day; the power bank would charge his devices each evening in the tent.

Implementation

The BigBlue clipped cleanly to the top pocket of his 65-litre rucksack using two of the four steel hooks. On clear days, walking roughly eight hours, the panel consistently delivered 60-80% of a full 20000mAh charge to the power bank. On overcast days and there were three of those over the week output dropped to 25-35%, enough to keep his phone and GPS comfortably charged but not fully replenish the bank.

Results

At no point during the seven days did any device run flat. The combination of panel and power bank gave him enough buffer to handle three consecutive cloudy days without anxiety. He noted the N-Type cells made a noticeable difference compared to a standard panel he’d used on a previous trip. Total kit weight for the charging setup was just over 900 grams acceptable for a week of independence from the grid.

Expert Insights From Our Solar Panel Installers About Solar Chargers

“The biggest mistake people make with solar chargers in the UK is expecting them to perform the same as they would in Spain or Portugal,” said one of our senior solar panel installers with over 12 years of experience. “In the UK, you need to plan around 3-4 hours of productive solar generation on an average summer day, and much less in autumn and winter. That’s why I always recommend higher-efficiency panels and a decent-capacity power bank as a buffer the combination is far more reliable than relying on either alone. Buy the most efficient panel your budget allows, and pair it with a power bank that can store more than you think you’ll need.”
