Buying a charger for someone else's phone — a family member, a gift, a shared household device — means you can't just go by your own device's needs. Here's how to get it right.
Step 1: Identify the Exact Phone Model
Charging needs vary meaningfully even within the same brand — a base iPhone and an iPhone Pro Max, or a Galaxy A-series and Galaxy S-series, often support different maximum charging wattages. Get the exact model before choosing wattage.
Step 2: Match Connector Type
- iPhone 15 and newer: USB-C
- iPhone 14 and earlier: Lightning
- Most modern Android phones: USB-C
- Some older or budget Android phones: Micro-USB — don't assume USB-C without checking
Step 3: Choose a Universal-Enough Wattage
If you're unsure of the exact supported wattage, a 20-30W charger is a safe universal choice — it fast-charges most phones without being wildly over-specced, and won't harm a phone that only supports lower wattage (the phone simply draws what it needs).
When in Doubt, Buy a Cable-Only Gift Instead
If you genuinely don't know the phone model or its charging needs, a genuine cable (matched to the connector type you're more confident about) is a safer, still-useful gift than guessing on charger wattage.
A Simple Buying Checklist
- Confirm exact phone model
- Confirm connector type (Lightning, USB-C, Micro-USB)
- Choose 20-30W if unsure of exact supported wattage
- Buy from a seller offering easy exchange if the connector turns out wrong
