Quick answer: Choose Apple 20W if you want the lower-cost option for everyday iPhone fast charging. Choose 40W if your compatible device can benefit from more available power or you want one adapter for higher-power USB-C devices. The phone or tablet controls how much power it accepts.
Compare current prices: view Apple 20W or view Apple 40W. Choose the plug and cable bundle shown on the live listing.

20W vs 40W: what changes?
| Factor | 20W | 40W |

| Available adapter power | Up to the 20W class | Higher available output for compatible devices |
| Best reason to buy | Value and basic fast charging | More headroom for supported devices |

Which one should you buy?
If your main goal is charging an iPhone and keeping cost down, start with 20W. If your device supports higher charging input, or you want a higher-power USB-C adapter for a broader set of compatible devices, compare the 40W options.
Do not assume a higher-wattage adapter forces extra power into the phone. Compatible USB-C charging negotiates power, and the device determines what it accepts.
Frequently asked questions
Will a 40W charger damage an iPhone?
A compatible USB-C charging system negotiates power. The iPhone controls the amount it accepts; the adapter’s rating is its maximum available output.
Is 40W twice as fast as 20W on every iPhone?
No. Charging speed depends on the iPhone model, battery level, temperature, cable and supported charging profile. This page does not claim a laboratory two-times result.
Which charger is better for everyday iPhone use?
Apple 20W is the lower-cost starting point for many iPhone buyers. Consider 40W when you also need more output for another compatible USB-C device.
Does the charger include a cable?
Bundle contents vary. Check the exact selected product and variant because a cable should only be expected when the live listing states that it is included.
Is Cash on Delivery available in Pakistan?
Yes. iSmart Hub’s published store information states that Cash on Delivery is available nationwide. Delivery timing depends on city and courier conditions.
