What Wattage Wireless Charger Do I Need?
The right wattage depends on your phone and usage patterns. For most people, a 15W Qi2 charger is the ideal choice in 2026.
Match the charger wattage to your phone maximum supported wattage. For most phones, 15W Qi2 is the ideal choice. Anything higher will not increase speed unless your phone specifically supports it.
The Simple Answer
For most people in 2026: a 15W Qi2 certified charger.
This charges the vast majority of current flagship phones at their maximum wireless speed, works with all older Qi devices, and is widely available at reasonable cost.
Matching Wattage to Your Phone
The golden rule: a charger can only charge at the maximum supported wattage of the lower of the two — phone or charger.
| Phone Max Wireless | Ideal Charger | Minimum Charger |
| 5W (earbuds, older phones) | 5-10W Qi | 5W Qi |
| 10W (Galaxy A55, mid-range) | 10-15W Qi | 10W Qi |
| 15W (Galaxy S23+, iPhone 15+) | 15W Qi2 | 15W Qi |
| 23W (Pixel 9 Pro on Pixel Stand) | Pixel Stand | 15W Qi |
| 25W (iPhone 16, MagSafe) | Official MagSafe / Qi2 | 15W Qi2 |
| 50W+ (OnePlus, Xiaomi) | Brand-specific charger | 15W Qi2 |
Use Cases by Wattage
5W — Basic/Overnight
Fine for: earbuds, wearables, overnight phone charging when speed does not matter.
Not ideal for: daytime phone charging, large batteries.
10W — Mid-Range Standard
Good for: Galaxy A55, older mid-range phones. Overnight or extended desk charging.
15W (Qi2) — The Sweet Spot
The best all-rounder choice for 2026. Charges all current flagships at maximum standard wireless speed. Future-proof due to Qi2 backward compatibility. Use this if you are unsure.
25W+ — Premium Fast Wireless
Meaningful for: iPhone 16 series (25W MagSafe), Pixel 9 Pro on Pixel Stand (23W).
Proprietary speeds of 25W+ for Android devices typically require brand-specific chargers.
50W+ — Ultra-Fast Proprietary
For: OnePlus AIRVOOC, Xiaomi HyperCharge users only. Requires the manufacturer charger.
What Power Adapter Do I Need?
The charger wattage is only realised with an adequate power adapter:
| Charger Wattage | Minimum Adapter | Recommended Adapter |
| 5W | 5W USB-A | 10W USB-C |
| 10W | 15W USB-C PD | 20W USB-C PD |
| 15W | 20W USB-C PD | 25W USB-C PD |
| 25W | 25W USB-C PD | 30W USB-C PD |
Always use a USB-C Power Delivery (PD) adapter, not a USB-A adapter, for best performance with modern wireless chargers.
