Quick answer: what is the best power bank for Glastonbury?
The UGREEN Nexode 25K (~£65–£85) is the best all-round power bank for Glastonbury — 93Wh capacity, 130W USB-C PD for laptop charging, three output ports, and enough capacity to cover 4 days of phone charging comfortably. For budget: Anker 325 PowerCore 20K (~£25–£35). For a group sharing at the campsite: add an EcoFlow RIVER 2 Pro power station (~£400–£500).
Glastonbury is a 4-day festival with no mains power access in the campsites. Your phone is your navigation system, your ticket, your emergency contact, your camera, and your festival schedule. Running out of battery is not an inconvenience — it is a genuine problem on a 900-acre site with 200,000 people.

How much battery do I need for Glastonbury?
Quick answer: what size power bank do I need for a 4-day festival?
For one person using a modern smartphone: a 20,000–25,000mAh power bank covers 4–5 full phone charges — enough for the full Glastonbury weekend with careful use. If you also use a tablet, camera, or wireless earbuds, go for 25,000mAh+. For charging a laptop: you need a bank with 65W+ USB-C PD output — the UGREEN Nexode 25K or Anker 737 handle this.
| Device | Battery size | 20,000mAh bank charges | 25,000mAh bank charges |
|---|---|---|---|
| iPhone 15 | 12.7Wh | ~4–5 full charges | ~6 full charges |
| Samsung S24 | 17.3Wh | ~3–4 full charges | ~5 full charges |
| AirPods Pro case | 1.6Wh | ~30 charges | ~40 charges |
| MacBook Air M2 | 52.6Wh | ~0.8 charges | ~1 charge |
Best power banks for Glastonbury by budget
Budget: under £40
Anker 325 PowerCore 20K (~£25–£35) — the most trusted budget option. Anker’s quality control at this price point is consistently reliable. USB-A only at 15W — slower charging but perfectly adequate for phones across a 4-day festival. No laptop charging.
Xiaomi PB3 20K (~£28–£40) — 50W USB-C PD, compact, reliable. Good step up from the Anker 325 if you have a modern phone that benefits from fast charging.
Mid-range: £40–£90
Anker 737 PowerCore 24K (~£70–£90) — 140W USB-C PD, capable of charging a laptop at full speed, digital display showing exact battery percentage. The right choice for anyone bringing a laptop to Glastonbury or wanting maximum charging speed.
UGREEN Nexode 25K (~£65–£85) — 130W USB-C PD, three simultaneous output ports (charge phone, laptop, and earbuds at the same time), GaN technology keeping it compact. The best overall festival power bank for most buyers.
For a group sharing at the campsite
Quick answer: can you bring a power station to Glastonbury?
Yes — Glastonbury permits portable power stations in the campsite. A shared EcoFlow RIVER 2 Pro (768Wh, ~£400–£500) at your pitch means everyone in the group charges their phones, banks, and cameras simultaneously rather than waiting for individual banks to cycle. For a group of four, the cost per person (~£100) is very reasonable for 4 days of unlimited charging. Check the current Glastonbury rules on the official site before bringing one.
Glastonbury power bank tips
- Charge your power bank fully the night before you travel — do not arrive at the campsite with a half-empty bank
- Keep your power bank in your day bag at all times on site — do not leave it in the tent. If it is in the tent, it is not charging your phone when you need it
- Download the Glastonbury app and your tickets offline before you lose signal — the site can have patchy coverage at peak times
- Take a short USB-C cable (30cm) for charging in your pocket rather than dangling a long cable
- Turn off background app refresh and reduce screen brightness — your phone uses significantly less battery in festival mode
- Enable Low Power Mode from day one rather than waiting until the battery is at 20%
Charging at Glastonbury — what is available on site
Quick answer: are there phone charging points at Glastonbury?
Yes — Glastonbury has dedicated phone charging stations (usually EE Charging Lounges) at various points around the site. These have queues. They are useful for topping up when your power bank runs low, but relying solely on on-site charging for a 4-day festival is not practical. Bring your own power bank as the primary charging solution — on-site charging as backup only.
