Chargers are sold on a single number — 20W, 30W, 65W — and that number tells you the ceiling, not what your phone will actually draw. Buying more watts than your device can accept is money spent on nothing.
What your device actually pulls
| Device | Useful charger | Beyond this does nothing |
|---|---|---|
| Budget Android phone | 18-20W | Yes |
| Mid-range Android (2023+) | 30-45W | Depends on the phone |
| iPhone 12 and later | 20-30W | Above 30W, yes |
| Tablet | 30W | Mostly |
| Thin-and-light laptop | 45-65W | Depends on the laptop |
| Two devices at once | 45-65W dual port | No — this is where high wattage earns its price |
The rule that saves money
A charger never forces power into a device. Your phone negotiates what it will accept and takes that much. A 65W charger on a 20W phone charges at 20W — no faster, no damage, just unused headroom.
So the reason to buy a higher-wattage charger is not speed on one phone. It is: charging a laptop, charging two things simultaneously at full speed, or future-proofing for the next device.
Where the wattage goes on a dual-port charger
This is the detail listings hide. A "45W dual port" charger is usually 45W total, split when both ports are in use — often 30W and 15W, not 45W each. Check the split before assuming you can fast-charge two phones at once.
The Salpido WC-05 is a 45W dual-port unit at Rs 899, which covers a phone and a second device. The WC-10 at 30W suits a single modern phone. The WC-07 at 65W is the one to pick if a laptop is in the mix.
PD and QC: do you need both?
Power Delivery (PD) is the USB-C standard used by iPhones, iPads, laptops and most modern Android phones. Quick Charge (QC) is Qualcomm's standard, common on older Android. A charger supporting both covers everything in a mixed household, which is the realistic case in most Indian homes.
The cable is half the equation
A 65W charger paired with a cable rated for 60W delivers 60W. Worse, a cheap unmarked cable may deliver 15W regardless of what either end can do. For anything above 30W, the cable needs to be rated for it — check for an e-marker chip on USB-C to USB-C cables. Salpido's SDC10C Type-C to Type-C is built for this.
Do you still need an extension board?
In most Indian homes, yes — wall sockets are rarely where the devices are. A board with built-in USB ports removes two adapters from the equation. The WC-08 and WC-09 extension boards handle this.
Common questions
Will a 65W charger damage my phone? No. The phone controls the draw.
Why is my phone charging slowly on a fast charger? Usually the cable, or the phone throttling because it is hot, or because it is above 80% where charging deliberately slows.
Is GaN worth paying for? GaN chargers are smaller and run cooler at the same wattage. Above 45W it is worth it for the size; below, less so.
Can I use my laptop charger for my phone? With a USB-C PD charger, yes, safely.
