Choosing the Best Power Bank for Your Tablet in the UK (2025)

Tablets like iPads or Android models (e.g., Samsung Galaxy Tabs) typically have larger batteries (8,000–12,000mAh), so a good power bank needs at least 10,000mAh capacity for a meaningful top-up (ideally 20,000mAh+ for 1–2 full charges). Prioritize USB-C Power Delivery (PD) support at 30W+ for fast charging—iPads max out around 30W, while some Android tablets handle 45W. Look for multiple ports, airline-safe designs (under 100Wh/27,000mAh), and UKCA/CE certifications for safety. Reputable brands like Anker dominate UK reviews for reliability and fast recharge times.

Based on expert tests from sources, here are the top picks for 2025. Prices are approximate (check retailers like Amazon UK or Currys for deals).
