Looking for a power bank and feel like they all look the same? Here's a guide to save you from a disappointing purchase — in 4 simple questions.
1. How much capacity (mAh) do you really need?
10,000mAh — About 2 iPhone charges. Perfect for daily use and fitting in your pocket. 20,000mAh — About 4 charges, the choice for trips, reserve duty, and flights. 25,000mAh and above — For heavy travelers and those who also charge laptops.
2. What are watts (W) and why are they more important than capacity?
The wattage determines how fast you'll charge: 20–30W is enough for a phone. 45W will also charge a tablet quickly. 65W+ enters laptop territory, and 100W+ will charge a MacBook Pro like the original charger. Rule of thumb: don't buy less than 20W in 2026.
3. Magnetic (MagSafe) — Is it worth it?
If you have an iPhone 12 or newer — yes. A magnetic charger attaches to the back of the phone and charges without any cable. It's the type of product that after a week you'll wonder how you lived without it.
4. How to identify a reliable brand?
Stick with well-known brands — UGREEN, Baseus, Vention, Anker — with safety standards (CE/FCC). A battery is not a place to save money: a cheap unknown charger can swell, overheat, and even endanger your phone.
