Portable Power Bank Camping Guide: 18 Top UK Picks

No signal is inconvenient, but no battery is trip-ending. The simplest way to keep your phone, camera, head-torch and GPS alive beyond the first night is to pack a high-capacity, rugged power bank. Aim for at least 10,000 mAh for a weekend wander; step up to 20,000 mAh or more – ideally with fast-charge USB-C and a solar trickle panel – if you’re pitching up for longer.

Because many UK campsites, bothies and wild pitches have fewer plug sockets than sheep, a dependable battery pack has become the modern camp stove: small, light and capable of powering half your kit. This guide runs through 18 units we’ve sweat-tested from Snowdonia car parks to Cairngorm plateaus, explains how to match capacity to trip length, breaks down charging maths in plain English, and shares safety, care and airline tips.

Still undecided between a palm-sized power bank and a plug-laden station? We compare both, so you only carry what you’ll use.

1. Anker PowerCore Solar 20K

1. Anker PowerCore Solar 20K

Key specs at a glance

• Capacity – 20,000 mAh / 74 Wh
• Rugged rating – IP65 dust & rain proof
• Solar panel – integrated 5 W mono cell
• Outputs – USB-C PD 20 W (in/out), 2 × USB-A 15 W
• Extras – carabiner loop, LED fuel gauge
• Weight – ≈ 550 g

Why it’s great for camping

Clip it to your pack and the 5 W panel trickles charge while you walk, so you hit camp with more juice than you started with. The shock-resistant shell laughs off rocky drops, and the IP65 seals keep Lake District drizzle out of the ports. One full tank equals roughly four iPhone 15 refuels or two GoPro batteries plus a head-torch, making it a solid weekend-to-week-long companion.

Things to watch out for

Think of the panel as a maintainer, not a refiller – a full solar recharge needs 25–30 hours of strong sun. At 550 g it’s no featherweight; ultralight hikers may prefer a smaller pack and separate folding panel.

2. Juice ECO 5 Charge 15,000 mAh

Key specs at a glance

• Capacity – 15,000 mAh / 55 Wh
• Output – USB-C PD 18 W (in/out), 2 × USB-A 12 W
• Shell – plant-based, biodegradable corn polymer
• Indicator – colour LED bar shows 0–100 % in 25 % steps
• Weight – ≈ 295 g (about the same as a packet of custard creams)
• Origin – designed by UK brand Juice, assembled in an ISO14001 factory

Why it’s great for camping

A 15 Ah cell hits the festival sweet spot: roughly three full smartphone charges or one phone, a GoPro and your Bluetooth speaker before you need a mains socket. At under 300 g it slips easily into a hip-belt pocket, and the rounded corners won’t snag tent fabric. The biodegradable outer casing feels grippy even with sunscreen-slick fingers, so you’re less likely to fumble it in the mud. Fast 18 W USB-C tops a modern phone from 0–50 % in about 30 minutes—handy for quick turnarounds between hikes.

Things to watch out for

• Lacks any IP rating, so stash it in a dry sack when the sky opens.
• 18 W is fine for phones and tablets but wheezes on USB-C laptops.
• No pass-through charging, meaning you can’t power devices while the bank itself is recharging.

3. Nitecore NPB4 Waterproof 20,000 mAh

If your weekend plans involve Scottish bog trots, pack-rafts or a windswept Bothy night, the NPB4 is the insurance policy your gadgets deserve. It’s one of the very few portable power bank camping options that can literally take a swim and keep outputting power at –10 °C.

Key specs at a glance

• Capacity – 20,000 mAh / 74 Wh
• Waterproof – IP68 submersible to 2 m for 30 min
• Outputs – USB-C PD 20 W (in/out), 2 × USB-A QC 3.0 18 W
• Extras – lockable port cover, constant-on LED fuel gauge
• Weight – ≈ 375 g (lighter than most waterproof peers)

Why it’s great for camping

Drop it in a stream, fish it out, plug in your phone – it just works. The hardy Li-ion cells are rated for –10 °C, so winter bivvies won’t cripple capacity. With 74 Wh on tap you can refill an iPhone 15 about four times or give a USB head-torch nightly top-ups for a week.

Things to watch out for

• Glossy casing picks up scratches and fingerprints fast.
• Single USB-C port limits simultaneous fast charging for multi-device power users.

4. Powertraveller Harrier 25 (25,600 mAh)

Designed by the same British brand trusted on Everest expeditions, the Harrier 25 blurs the line between pocket battery and mini-generator. If your kit list includes a mirrorless camera, drone or USB-C laptop, this brick earns its space in your rucksack.

Key specs at a glance

• Capacity – 25,600 mAh / 94.7 Wh
• Outputs – USB-C PD 60 W (in/out), DC barrel 12–25 V / 60 W, 2 × USB-A 18 W
• Extras – integrated 150 lumen torch, rubberised impact bumpers, pass-through charging
• Weight – ≈ 540 g (pint-glass territory)

Why it’s great for camping

The 60 W USB-C port fast-charges a MacBook Air to 50 % in under an hour, while the variable-voltage DC socket powers drone or DSLR battery chargers directly—no inverter loss. That flexibility turns one portable power bank camping solution into a hub for your entire photo rig. Thick rubber edges survive being boot-kicked around a bothy floor, and the built-in torch is bright enough for late-night tent faffs.

Things to watch out for

• Premium price tag (about £119 RRP) reflects its pro focus.
• DC adaptor tips are an extra purchase.
• At half a kilo it’s base-camp friendly but hefty for fast-and-light trips.

5. RAVPower Rugged Solar 30,000 mAh

5. RAVPower Rugged Solar 30,000 mAh

Key specs at a glance

• Capacity – 30,000 mAh / 111 Wh
• Solar – twin fold-out 15 W mono-crystalline panels (30 W total surface)
• Outputs – USB-C PD 20 W (in/out), 2 × USB-A 18 W, 10 W Qi wireless pad
• Extras – 3-mode LED floodlight, lanyard loop, shock-absorbing bumper
• Weight – ≈ 690 g

Why it’s great for camping

Think of this as a campsite micro-generator. Unfold the panels on your dashboard or picnic table and you can claw back roughly 6 Ah of charge on a bright summer day—enough for another full smartphone top-up without touching the main cell. The rubberised shell shrugs off knocks, and the 10 W Qi pad keeps the picnic bench cable-free when friends need an emergency boost. At 111 Wh it still squeaks under CAA limits for hand luggage, so it can jet off to alpine huts as well as UK fells.

Things to watch out for

• The brick-like 690 g mass suits car or canoe campers better than ounce-counting hikers.
• Treat the fold-out panels gently; bending them while damp can fracture the cells.
• Full solar refills are optimistic in typical British weather—pack a USB-C wall plug as plan B.

6. Goal Zero Venture 35

Travelling light but still want hardware that can take a beating? The Venture 35 is Goal Zero’s pocket-size bruiser: small enough for summit camps, tough enough for winter belays and—crucially—airline-friendly at just 35 Wh.

Key specs at a glance

• Capacity – 9,600 mAh / 35 Wh
• Rugged rating – IP67 dust-tight & waterproof (30 min @ 1 m)
• Outputs – USB-C PD 18 W (in/out), 2 × USB-A 12 W
• Extras – integrated 50 lumen torch, detachable rubber cable keeper
• Solar ready – 0–100 % in ≈ 3 hrs from a Goal Zero Nomad 10 panel
• Weight – ≈ 287 g

Why it’s great for camping

Its hard-rubber armour and port plug laugh at sideways rain, while the sub-100 Wh battery avoids CAA paperwork for flights to the Alps. One charge equals about one smartphone and one GoPro top-up—ideal for overnight wild bivvies or fast-and-light scrambles. Pair it with a Nomad foldable panel and you can be back to full by lunchtime on a blue-sky day.

Things to watch out for

• At 35 Wh the capacity is limited; power-hungry users will need a second bank.
• Higher cost per watt-hour than generic brands.
• USB-A ports max out at 12 W, so tablet charging is slower.

7. Zendure SuperTank Pro 100 W (26,800 mAh)

Need mains-like power for editing trail footage or flying drones yet still count grams? The aluminium-clad SuperTank Pro squeezes laptop-class output and a geek-pleasing OLED read-out into a palm-sized block that tucks neatly beside your stove.

Key specs at a glance

• Capacity – 26,800 mAh / 96 Wh

• Display – real-time voltage, current and temperature OLED screen
• Passthrough – yes, with power-distribution auto management
• Shell – anodised aluminium for heat dissipation
• Weight – ≈ 580 g

Why it’s great for camping

A single 100 W port juices a MacBook Air from flat to 50 % in under 40 minutes, while the remaining ports keep your phone, camera and head-torch topped up simultaneously. The live watt-hour counter helps ration energy on multi-day treks, and pass-through means you can daisy-chain a solar panel without unpacking cables.

Things to watch out for

• Needs a 100 W USB-C wall brick (sold separately) for fastest refill.
• No IP rating—stash in a dry bag when the heavens open.
• Premium pricing pushes it into “prosumer” territory.

8. BioLite Charge 80 PD 20 K

BioLite designed the Charge 80 to dovetail with its head-torches, lanterns and stove fans, so one brick can fuel your whole BioLite ecosystem plus a phone or two. The flat slab slips neatly under a sleeping-mat corner, keeping cells warm and efficient on frosty nights. Real-world tests gave four full smartphone refills or a phone, GoPro and BioLite 330 headlamp over a three-day hike—respectable stamina for a mid-weight portable power bank camping solution.

Things to watch out for

• No pass-through charging, so you can’t power gadgets while topping up the bank.
• 18 W USB-C is speedy for phones but crawls with laptops.
• IP rating is absent; stow it in a dry sack during wet spells.

9. OtterBox Fast Charge Rugged 15 K

Key specs at a glance

• Capacity – 15,000 mAh / 55 Wh
• Outputs – 18 W USB-C PD (in/out) and 15 W USB-A
• Protection – MIL-STD-810G 2 m drop rating, IP54 splash-proof
• Extras – ridged anti-slip shell, lanyard loop, four-LED gauge
• Weight – ≈ 330 g

Why it’s great for camping

OtterBox took the shock armour from its famous phone cases and wrapped it round a battery. The grippy ribs let you yank the bank from a wet jacket pocket without fumbling, and the corner bumpers shrug off bench-top tumbles. A full tank equals roughly three modern phone recharges, or one phone plus a pair of GoPro batteries—plenty for a long weekend away. The 18 W USB-C port hits 0–50 % on most smartphones in about half an hour, so you can top up during a brew stop rather than babysit a cable all evening.

Things to watch out for

• IP54 copes with drizzle, not submersion—stash in a dry bag during downpours.
• Heavier than many 15 Ah rivals at the same price.
• Only one USB-C port, so no twin fast-charging.

10. INIU PowerPaw 10 K (Budget Pick)

10. INIU PowerPaw 10 K (Budget Pick)

Key specs at a glance

• Capacity – 10,000 mAh / 37 Wh

Why it’s great for camping

For less than the price of a takeaway, this dinky slab gives you two full phone refuels or a night of head-torch top-ups—ideal as an emergency portable power bank camping spare. At under 200 g it slips into a hip-belt pocket, and the bright torch saves rummaging for a separate light when nature calls at 3 am. The 22.5 W USB-C port juices modern phones from 0–50 % in roughly 25 minutes, handy for quick brew-stop boosts.

Things to watch out for

• Limited stamina: power-hungry gadgets will drain it in a day.
• No IP rating—rain and electronics don’t mix; use a zip-lock bag.
• Torch shares the main cell, so long light sessions cut into charging capacity.

• Weight – 630 g; size 168 × 82 × 28 mm

Why it’s great for camping

Hauling a laptop, camera and phone? ChargeUp Pro dishes out desktop-class punch from a rucksack pocket. The 140 W USB-C port keeps a 16-inch MacBook Pro alive while you cull RAWs, and the 65 W second port still fast-charges a tablet or drone hub. At 99 Wh it slips under airline rules, so your portable power bank camping rig is flight-ready.

Things to watch out for

• £150 RRP means you pay a premium per watt-hour.
• Glossy ABS shows scratches and sunscreen smears.
• No legacy USB-A beyond one 18 W port; pack extra USB-C cables.

UGREEN’s brick is the pocket powerhouse for gadget-heavy campers. The 100 W USB-C port keeps a MacBook or Steam Deck running at full tilt while the 45 W port fast-charges your phone or drone hub—no juggling cables. Rounded, rubber-edged corners slide neatly into hammock side-pockets and don’t chew through ultralight tent fabric. In real-world tests we squeezed out two laptop top-ups plus a handful of phone charges before hunting for mains, making it a sweet spot between true power stations and lighter day-hike banks.

Things to watch out for

• Glossy shell loves fingerprints and micro-scratches—wrap it in a buff if aesthetics bother you.
• Only IPX2 drip-resistance, so stash it in a dry bag during British downpours.
• Needs a beefy 100 W wall brick (sold separately) to hit its rapid 90-minute refill claim.

15. Jackery Explorer 240 Portable Power Station

Technically a “mini-generator” rather than a pocket bank, the Explorer 240 is still small enough for car boots and cabin bags yet big enough to run campsite luxuries you can’t power over USB. If you’re glamping, managing a CPAP machine, or want ice-cold milk from a 12 V cool box, this plug-and-play cube hits a sweet middle ground between featherweight batteries and hulking 1 kWh stations.

Key specs at a glance

• Capacity – 240 Wh (67,200 mAh @ 3.6 V)
• Outputs – 230 V AC 200 W (400 W surge), regulated 12 V car port 10 A, 2 × USB-A 12 W
• Re-charge – wall (7 hrs), solar (SolarSaga 100 panel ≈ 5.5 hrs), car (6 hrs)
• Screen – LCD shows input, output and percentage
• Weight – ≈ 3 kg; size 23 × 14 × 20 cm

Why it’s great for camping

A single charge powers a 40 W mini-projector for five hours, a CPAP overnight, or keeps a 30 L compressor cool box humming through a weekend heatwave. The built-in handle makes relocation easy, and the pure-sine AC socket is safe for delicate electronics like camera chargers or laptops. Pair it with Jackery’s foldable SolarSaga panel and you’ve got silent, solar-fed off-grid power that still fits under the camp table.

Things to watch out for

• Three kilograms is rucksack-unfriendly; think car, van or canoe camping.
• 240 Wh exceeds the 160 Wh flight limit, so it’s not airline-legal.
• AC outlet caps at 200 W continuous—hair-dryers and induction hobs will trip it.

16. EcoFlow River 2

EcoFlow’s River 2 bridges the gap between pocket banks and true generators, delivering mains-style power in a loaf-sized 3.5 kg package.

Key specs at a glance

• Capacity – 256 Wh LiFePO₄ (≈ 70,000 mAh), rated for 3,000 + cycles

• 100 W USB-C plus 300 W AC run laptops, pumps and mini-fridges.

Things to watch out for

• Cooling fan is audible above 200 W—noticeable on silent pitches.
• 3.5 kg is portable, just not backpack-friendly.
• Non-EcoFlow solar panels need an extra MC4-to-XT60 cable.

17. DJI Power 500 (Drone-Friendly Pick)

17. DJI Power 500 (Drone-Friendly Pick)

Key specs at a glance

• Capacity – 500 Wh / 135 Ah

• Chemistry – Li-ion NMC, 1,000-cycle life
• Build – stack-and-lock modular shell, LED status bar, quiet <30 dB cooling
• Weight & size – ≈ 6 kg; 270 × 190 × 190 mm

Why it’s great for camping

Normal banks need the DJI hub; the Power 500 skips it, topping up a Mini 4 Pro battery four times on one tank. The 140 W USB-C port keeps a laptop humming while twin AC sockets run a mini-projector or low-watts kettle for brew o’clock. When van-life calls, clip on extra modules to double or triple capacity without rewiring.

Things to watch out for

• Premium cost (about £499).
• Six-kilo heft suits cars, not backpacks.
• 500 Wh exceeds airline limits, so it’s road-trip only.
• Early UK stock is limited—plan ahead.

18. Anker Solix F3800 (Home & RV Back-up)

Key specs at a glance

• Capacity – 3.84 kWh base (expandable to 26 kWh with extra packs)
• Outputs – 2 × 240 V AC 3,800 W (7,600 W surge), 2 × USB-C 100 W, 4 × USB-A 18 W, 30 A RV port, dual 12 V car sockets
• Input – 2,400 W AC or 2,400 W solar (11–60 V, 24 V array recommended)
• Mobility – telescopic handle & puncture-proof wheels
• Chem­istry – LFP rated 3,000+ cycles
• Weight – ≈ 30 kg; suitcase size 68 × 34 × 43 cm

Why it’s great for camping

If your idea of “portable power bank camping” involves an induction hob, e-bike charger or caravan A/C, this rolling powerhouse has you covered. The 3.8 kWh battery runs a 60 W fridge for two full days, boils a travel kettle in minutes, and still leaves enough juice to blitz-charge phones from the 100 W USB-C ports. Plug in a 2.4 kW solar array at base-camp and you’ve got a silent, endlessly renewable off-grid grid that doubles as home blackout insurance.

Things to watch out for

• Thirty kilos and suitcase dimensions scream car-camping only—don’t plan to lug it up Scafell.
• Needs 24 V (or higher) solar strings; 12 V panels won’t wake it up.
• Overkill on capacity and price if you mainly top up phones and head-torches.

How to Choose the Right Power Bank for Your Camping Adventures

Scrolling through 18 options can feel like picking a needle from a hayfield. The quickest way to narrow things down is to map your real-world energy needs to capacity, outputs, weight and weather protection. Use the check-points below and you’ll land on the perfect portable power bank camping companion in minutes.

Match capacity to trip length and device load

A bank’s milliamp-hours (mAh) is only half the story: watt-hours (Wh) factor in voltage and give a truer picture. Convert with

Wh = (mAh × V) ÷ 1,000

Then compare to your devices. An iPhone 15 (12.7 Wh) will drain roughly 13 % of a 100 Wh pack each time it charges.

Pro tip: Mix and match—carry a feather-weight 10 K for summit pushes and leave the bigger bank in the tent.

Output ports and charging speed explained

• USB-C Power Delivery tiers: 18 W (phones), 45 W (tablets), 60–100 W (most laptops), 140 W (high-end MacBooks).
• Quick Charge 3.0/4.0 on USB-A is still handy for legacy cables.
• AC sockets on power stations open the door to cool boxes, projectors and CPAP machines—check continuous watt rating, not just surge.

Rule of thumb: your power bank’s maximum output should equal at least 80 % of your device’s charger rating to avoid throttling.

Weight, size and packability

Every 10 Wh adds roughly 35–40 g. Balance that against how far you’ll carry it:

• <250 g: pocket size, fine for day hikes.
• 250–700 g: “brick” class, good for multi-day treks or festival camps.
• 3 kg+: power stations—car, canoe or camper van territory.

Distribute bricks close to your back’s centreline to keep gait natural; stow lighter banks in hip pockets for quick access.

Durability & weatherproof ratings

Dropping a bank into bog water is only funny if it still works. Look for:

MIL-STD-810G drop tests add impact assurance; temperature ranges (e.g., –10 °C to 45 °C) matter for winter bivvies.

Solar integration: gimmick or game-changer?

In the UK’s middling sunshine, expect 4–6 Wh per day from a 5 W trickle panel—great for topping up a phone, hopeless for refilling 30 Ah bricks. Detachable 20–100 W folding panels are far more effective: budget roughly 1 W of panel per Wh you want to harvest daily.

Safety features & airline regulations

Modern packs bundle over-temperature, short-circuit and cell-balancing tech—make sure yours does. Flying? Civil Aviation Authority rules allow:

• Up to 100 Wh: carry-on without paperwork.
• 100–160 Wh: airline approval required (email 48 h ahead).

• 160 Wh: banished to the hold—or your road trip.

Tape exposed terminals, stash in hand luggage and you’ll sail through security.

Using and Maintaining Your Power Bank in the Wild

High-spec batteries lose their edge fast if they’re mistreated. A couple of simple routines before, during and after your trip will keep any portable power bank camping companion performing like new and, crucially, stop it dying just when the sunset is perfect.

Pre-trip checklist

• Fully charge the bank and confirm the LED or OLED reads 100 %.
• Update firmware via the maker’s app if your model supports it – fixes often improve efficiency and safety limits.
• Pack the right cables: one short fast-charge USB-C for trailside boosts, one longer lead for tent use, plus any proprietary DC tips.
• Throw in a 20 W+ wall plug or your folding solar panel so you’re not hostage to a single charging source.
• Test every port the night before. A £5 cable can fail; better to discover that in your kitchen than on Kinder Scout.
• Stash the bank in a zip-lock or IP-rated dry sack if the unit itself lacks sealing.

Efficient charging habits on site

1. Charge the hungriest item first (usually a phone or drone battery) while the bank is at its most efficient voltage.
2. Enable flight mode or low-power mode on devices; you’ll save 20–30 % energy per cycle.
3. Top up during daylight breaks rather than overnight. Warm batteries accept charge faster, and you avoid accidental deep-discharge if the cable disconnects while you sleep.
4. If using a solar panel, angle it roughly 45° south (in the UK) and plug in the bank, not your phone. The bank’s MPPT controller is far better at handling fluctuating light.
5. Daisy-chain sparingly – each extra cable run wastes precious milliamps.

Storage, cleaning, and lifespan extension

Lithium cells prefer a Goldilocks zone. Store the bank at 40–60 % charge in a cool, dry cupboard (≈15 °C-25 °C). Wipe mud off the shell with a damp cloth, then dry the ports using a soft brush or compressed air. Avoid chemical cleaners; isopropyl alcohol on a cotton swab is safe for stubborn grime. Every three months, cycle the battery to 100 % and back to keep cell balancing in check.

Troubleshooting common issues

• Bank won’t charge: swap cables first, then wall adaptor; 80 % of faults trace back to frayed leads or under-rated plugs.
• Ports fogged with condensation: power down, shake gently, and air-dry in a sealed bag with silica gel for 12 h.
• Output lights flash but no current flows: look for a tiny reset pinhole; hold for 5 s to reboot protection circuitry.
• Rapid capacity drop in cold weather: keep the bank inside an inner pocket or your sleeping bag; lithium chemistry sags below 0 °C but rebounds when warmed.
• Solar input reads zero: check panel orientation, clean dust from cells, and confirm you’re within the bank’s input voltage range.

Follow these fixes and maintenance tips and your power pack will still be juicing gadgets long after the tent pegs have rusted.

Pick the smallest kit that meets your watt-hour needs. Pocket power banks (e.g. #6 Goal Zero Venture 35) excel for backpacking where you only need USB juice. Portable power stations such as #15 Jackery Explorer 240 add 230 V sockets for cool boxes, CPAP or projectors, but they live in the boot, not your rucksack.

How long will a 20,000 mAh power bank last?

Convert to watt-hours: 20,000 mAh × 3.7 V ÷ 1,000 ≈ 74 Wh. Divide by your device’s battery: an iPhone 15 (≈12.7 Wh) gets about 5 full charges; a GoPro Hero 12 (≈4.4 Wh) sees 16 top-ups. Real-world inefficiencies knock 10–15 % off those headline figures.

Can I take a 30,000 mAh power bank on a plane?

Maybe. At 3.7 V that equals 111 Wh, landing in the Civil Aviation Authority’s 100–160 Wh bracket. You must carry it in hand luggage and request airline approval at least 48 hours before departure. Packs above 160 Wh are forbidden in cabins and holds.

Is solar charging in the UK actually worth it?

Trickle panels on a portable power bank camping unit add insurance, not full refills. Expect 4–6 Wh per sunny day from a 5 W panel—roughly 20 % of a 10 Ah bank. A separate 20–100 W folding panel is far more productive; budget about 1 W of panel for every Wh you hope to harvest daily.

How safe are power banks in the rain?

Check the IP code. IP54 survives drizzle; IP67 or IP68 (e.g. Nitecore NPB4) handles full dunkings. Non-sealed units should live in a dry bag. Never charge devices when connectors are wet—residual moisture can short contacts and trigger the bank’s safety cut-off.

Wrap-up Tips Before You Head Out

Think of your power bank as another piece of hard-wearing kit: if it matches your mileage and the weather, you’ll forget it’s even there. Before you hit the trail, double-check the big four:

• Capacity – pick enough watt-hours for every device, plus a 20 % buffer.
• Durability – look for IP and drop ratings that suit the forecast.
• Output – make sure the fastest port equals at least 80 % of your gadget’s charger.
• Weight – carry only what you’ll actually drain between plug-ins.

Pairing the right brick with the charging habits we covered earlier means no more battery anxiety, whether you’re bagging Wainwrights or glamping in Cornwall. Ready to gear up? Browse the full camping tech range—and grab next-day delivery—over at Take a Hike UK. Stay powered, pitch happy!
