Frequently Asked Questions
Are these power banks allowed on UK flights?
Yes. Both the UGREEN 200W (90 Wh) and UGREEN 145W (72 Wh) are below the 100 Wh airline carry-on limit. Power banks must go in carry-on luggage — never in checked bags. UK, EU and most international airlines follow IATA's 100 Wh rule.
How many days will a 25,000 mAh power bank last at a festival?
For a typical festival-goer, 25,000 mAh provides 5–6 full charges for an iPhone 16 or 4–5 charges for a Samsung Galaxy S25 — comfortably covering a 3-day weekend with moderate use. Factor in about 15% energy loss from voltage conversion.
Can I charge my laptop at a festival with these?
Yes. The UGREEN 200W charges MacBook Pro 16″ at full speed (100W) and any laptop via USB-C PD. The 145W is sufficient for MacBook Air, Dell XPS 13, and most ultrabooks. Both support pass-through, so you can charge the bank and your laptop at the same time.
What's the fastest way to recharge these power banks?
The UGREEN 200W supports 100W USB-C input and recharges in ~65 minutes with a 100W wall charger. The UGREEN 145W takes about 2.5 hours on a 65W charger. Always pair with a matching USB-C PD charger for fastest recharge.
200W or 145W — which should I buy for summer?
If you carry a laptop (especially a MacBook Pro 16″, XPS 15 or similar), the 200W at £59.99 is exceptional value — it's the only portable power bank that keeps large laptops charged at full speed. For phones, tablets and lighter laptops, the 145W at £49.99 is the smarter buy.
