20W, 30W, 45W or 70W — which charger do you need?
Walk into any accessory shop in Pakistan and you will be told a higher number is better. It is not that simple. Your device sets the ceiling, not the charger. Plug a phone that accepts 27W into a 70W charger and it draws 27W. The extra capacity does nothing.
What extra wattage actually buys you is headroom — the ability to charge something bigger, or several things at once.
20W — one phone, nothing else
Enough to fast-charge any modern phone. An iPhone 15 reaches 50% in about 26 minutes on 20W. It will charge a tablet, slowly.
Pick this if you want one small charger for one phone and nothing more. The Anker Zolo 20W is Rs 2,449 and weighs 49 g.
30W — a phone today, a tablet tomorrow
The sensible default. Same physical size as the 20W, but five output profiles from 5V to 20V instead of two, which means it can properly drive an iPad Pro or a lighter USB-C laptop rather than trickling into them.
For Rs 550 more than the 20W, this is the upgrade most people should take. The Anker Zolo 30W is Rs 2,999.
45W — a laptop charger that fits in a pocket
45W is real laptop territory — a MacBook Air charges at full speed. The Anker Nano 45W adds a live display showing actual wattage flowing into your device, which is genuinely useful for diagnosing a slow cable.
Rs 6,799. One caveat we state plainly: this is the Chinese-region unit, so the display text is in Chinese. Same 45W, same GaN internals, and it is why the price is what it is.
70W — the one that replaces your other chargers
Four ports. Any one of the three USB-C ports can deliver the full 70W alone. Share it and the power splits sensibly — 65W to a laptop with 5W left for earbuds, or 45W and 25W across two phones.
This is the travel charger that means you stop carrying three adapters. The Anker Zolo 70W 4-Port is Rs 8,999.
Will a bigger charger damage my phone?
No. USB Power Delivery is a negotiation — the device requests a voltage and current, and the charger supplies exactly that. A 70W charger hands a phone the same 27W a 30W charger would.
Two things nobody tells you
The cable matters as much as the charger. A cable rated for 60W will cap a 70W charger at 60W regardless. If charging is slower than expected, suspect the cable first.
None of these chargers includes a cable. Anker sells them on their own. We say so on every product page, because finding out after delivery is a bad way to learn it.

- One phone → 20W
