Quick Summary
- Best Overall: Anker 733 Power Bank (GaNPrime 65W) — huge capacity, fast charging, and robust enough for a muddy field

Festival season is here, and the last thing you want is a dead phone when you’re trying to find your friends in a sea of 80,000 people or capture that headline set. Whether you’re headed to Glastonbury, Reading, Leeds or a boutique weekender, a reliable portable charger is as essential as your wellies. In 2026, power banks have never been better — faster, lighter and more durable than ever before. We’ve tested the top options across every budget so you can arrive on site confident your battery will outlast the weekend. Here are the very best portable chargers for festivals right now.
What to Look For in a Festival Power Bank
- Capacity (mAh): For a three-day festival, aim for at least 20,000mAh. That gives most smartphones four or five full charges, leaving headroom for a friend’s emergency top-up.
- Charging speed: Look for USB-C Power Delivery (PD) or Quick Charge 3.0 support. Fast charging means less time tethered to your power bank and more time enjoying the music.
- Durability and weather resistance: Festival grounds are muddy, wet and chaotic. An IP54 rating or a rubberised, drop-resistant casing is well worth the slight extra cost.
- Size and weight: You’ll be carrying this in a bum bag or jacket pocket for hours. Under 400g is the sweet spot — powerful enough to be useful, light enough not to be a burden.

Our Top Picks
Anker 733 Power Bank (GaNPrime PowerCore 65W)
The Anker 733 is one of those rare products that genuinely does everything well. It packs a 10,000mAh battery alongside a built-in 65W GaN wall charger, meaning you get one compact unit that charges itself and your devices simultaneously — no need to carry a separate plug adapter to the campsite. It offers two USB-C ports and one USB-A, with the primary USB-C delivering 65W Power Delivery to top up a modern smartphone in under an hour. At just 272g it slips into a jacket pocket, and the matte-rubberised finish feels reassuringly solid even after a weekend’s abuse. For most festival-goers, this is the one.
Pros
- Built-in wall plug — one item to pack
- 65W USB-C PD charges phones incredibly fast
- Compact and light for its capacity
Cons
- 10,000mAh may not last a full four-day festival
- Pricier than basic power banks
Xiaomi 10000mAh Power Bank Pocket Edition Pro
Don’t let the low price fool you — the Xiaomi Pocket Edition Pro is a genuinely impressive piece of kit. Its 10,000mAh lithium-polymer cell will deliver around two and a half full charges for most iPhones or Android flagships, and it supports 33W fast charging via USB-C PD. It’s only 95mm long and weighs 160g, which means it genuinely disappears in your back pocket. The aluminium unibody construction feels far more premium than the price suggests, and it charges itself from flat in under 75 minutes. If you’re only heading to a day festival or a weekend event and travel light, this is an absolute steal.
Pros
- Exceptional value — premium feel at a budget price
- Tiny and lightweight at just 160g
- 33W fast charging via USB-C
Cons
- Only one output port limits simultaneous charging
- 10,000mAh won’t see you through four days
Goal Zero Sherpa 100 AC Power Bank
If you’re a serious festival camper — the kind who brings a mirrorless camera, a Bluetooth speaker and a laptop alongside their phone — the Goal Zero Sherpa 100 AC is in a league of its own. Its 25,600mAh capacity and 100W USB-C PD output make it one of the most capable portable chargers available to consumers in 2026. Crucially, it features a full UK AC outlet, allowing you to plug in standard devices directly. It’s also compatible with Goal Zero’s Nomad solar panels, so you can trickle-charge it via a panel attached to your tent during the day. Yes, it weighs 680g and costs a premium, but for the right festival-goer it’s transformative.
Pros
- Enormous 25,600mAh capacity for multi-day use
- Full AC outlet plus 100W USB-C PD
- Solar-panel compatible for off-grid top-ups
Cons
- Expensive — a significant investment
- 680g makes it too heavy for a pocket
Who Should Buy This?
If you’re attending a one or two-day festival and keeping things simple — one phone, minimal kit — the Xiaomi Pocket Edition Pro is all you need. It’s cheap enough that you won’t lose sleep if it gets lost in the mud, and small enough to slot into any pocket or small bag without weighing you down. For the majority of UK festival-goers attending events like Latitude, Boardmasters or Creamfields over a weekend, the Anker 733 hits the sweet spot perfectly, combining speed, capacity and the convenience of a built-in wall plug.
The Goal Zero Sherpa 100 AC is for a different kind of festival-goer entirely. If you’re a photographer shooting the weekend, a content creator who needs to keep a laptop running, or simply someone who likes to share charging duties with the whole camp, the investment makes complete sense. It’s also an excellent purchase if you regularly attend multi-day camping festivals year after year — amortised over several events, the cost becomes very reasonable for the reliability it provides.
Final Verdict
Choosing the best portable charger for your festival ultimately comes down to how long you’re going, how many devices you carry and how much you’re prepared to spend. For most people, the Anker 733 GaNPrime is the outstanding all-rounder — fast, compact and brilliantly designed. On a tight budget, the Xiaomi Pocket Edition Pro is remarkable value and will comfortably see a weekend warrior through. And if power is mission-critical, the Goal Zero Sherpa 100 AC is the closest thing to a portable mains socket you’ll find. Whichever you choose, your phone will thank you — and so will your mates when theirs dies at midnight.
Frequently Asked Questions
How much capacity (mAh) do I need for a 3-day festival?
For a three-day festival, aim for a minimum of 20,000mAh if you’re a heavy phone user. That typically provides four to six full charges for a modern smartphone. If you also use your phone as a camera frequently or want to share charges with friends, consider stepping up to 25,000mAh or more.
Are power banks allowed at UK festivals?
Yes, power banks are permitted at virtually all UK festivals, but there are important caveats. Most events restrict lithium-ion power banks to 27,000mAh (100Wh) or less when entering via the main gate, which aligns with airline regulations. Always check your specific festival’s terms, as some premium camping areas may have stricter rules about large battery packs.
Can I charge a power bank using a solar panel at a festival?
Yes — certain power banks, including the Goal Zero Sherpa 100 AC, are specifically designed to accept solar input. You can attach a compatible solar panel to your tent or gazebo and trickle-charge the bank throughout the day. It won’t replace a full charge rapidly, but it meaningfully extends your available power over a long weekend.
What’s the difference between USB-C PD and standard USB charging for power banks?
USB-C Power Delivery (PD) is a fast-charging standard that can deliver significantly more watts than a standard USB-A port — often 30W, 65W or even 100W compared to a typical 5W or 12W. In practice this means your phone charges in 30–60 minutes rather than two or three hours, which is incredibly valuable at a festival where your phone time is precious.
Should I charge my power bank before I leave for the festival?
Absolutely — always arrive with your power bank fully charged. Many festival sites have limited or expensive charging points, and queues can be long. Charge your power bank to 100% the night before you travel, and if possible pack a wall charger to top it up during any downtime in your tent or at a nearby charging station.
