Buying guides

• Power banks and flying: how many mAh can you take?

  The rule is simple: up to 100 Wh needs no approval, and it is worked out from the mAh, not from the size. Here is the formula and a ready table for the most common capacities.

• How many watts does your charger need? iPhone, Samsung and laptop explained

  20W is enough for most phones, Samsung's Plus and Ultra want 45W with PPS, and laptops start at 65W. The real numbers, what GaN means, and why the cable matters.

• MagSafe vs Qi2: what is the difference, and which one fits your phone?

  Both are magnetic wireless charging at roughly the same power. The difference is who makes it, which phones it works with, and the price. The straight answer is here.

• Which band fits your watch? Apple Watch, Whoop, Samsung and Huawei sizes, and the best material for Qatar's heat

  Apple has just two size groups, Whoop 5.0 bands differ from 4.0, and Samsung and Huawei use 20mm and 22mm. The full table, plus which material survives a Qatar summer.

• How to choose wireless earbuds: noise cancelling, battery, fit, and the car rule in Qatar

  Not all noise cancelling is equal, the ear-tip fit matters more than the brand, and one habit kills earbuds every Qatar summer. The full checklist before you buy.
