Power accessories are bought on trust: you can't see from a photo whether a power bank holds its stated capacity, whether an extension lead's surge protection is real, or whether a travel adapter will fall apart in a fortnight. Customer reviews expose all of it, which is why this category ranks power banks, extension leads, surge protectors, plugs and adapters by real ratings and review volume. The safe, honest kit floats to the top. Compare the current favourites below and check live prices on Amazon.

Frequently asked questions
What size power bank do I actually need?
Around 10,000mAh covers two full phone charges and still fits a pocket, which suits most people. Go bigger for tablets, trips or festivals, but remember real delivered capacity is typically 60 to 70 percent of the printed number.
Are cheap extension leads safe?
Stick to well-reviewed leads from recognised brands with genuine UK plugs and, ideally, surge protection. Reviews surface melted sockets and loose pins fast, so recent ratings are worth a skim before buying.
Can I take a power bank on a plane?
Yes, in hand luggage only, and most airlines cap capacity at 100Wh, which covers nearly all consumer power banks. Check the printed Wh figure before you fly.
