Anker’s 20W Nano costs less than Apple’s 20W adapter, making it a more affordable option for iPhone owners buying chargers.
Anker’s compact body, lighter weight and retractable prongs make it easier to carry, especially for users who frequently travel with devices.
Both chargers deliver up to 20W through USB Power Delivery, offering similar charging speeds on iPhones that support 20W charging.
Anker is the better buy for most iPhone owners. Its 20W Nano charger costs about USD 12 while the Apple 20W adapter costs USD 19, and the Anker unit is 45% smaller by volume, according to BGR. Both chargers deliver the same 20W of power, so charging speed is nearly identical on any iPhone that supports it. Apple still suits buyers who want an official accessory and a simple purchase. Anker suits people who care about price and portability. The sections below cover each point so you can decide with confidence.

Price is where the gap is easiest to see. BGR lists the Anker 20W Nano at USD 12 and the Apple 20W adapter at USD 19, which makes Anker about 37% cheaper. In a home with three or four iPhones, that difference adds up to a useful saving. Neither charger usually comes with a cable, so budget for one if you do not already own a USB-C cable. Some sellers, such as AvaNext in Pakistan, list both chargers and bundle a data cable with certain listings, so read the product page carefully. Anker prices also tend to drop during sale events like Prime Day, which runs on October 6 and 7, so a patient buyer can often pay even less.
Anker wins this round by a clear margin. BGR measures the 20W Nano at about 1.6 cubic inches and 1.2 ounces, which makes it 45% smaller by volume and 42% lighter than Apple's adapter. The difference is easy to notice when you hold the two side by side, and it matters more when you carry the charger every day. A lighter adapter also puts less strain on a loose wall socket, which is common in older homes and hotel rooms.
Speed is almost the same, since both chargers use USB Power Delivery at 20W. Apple says an iPhone 8 or newer can reach about 50% battery in 30 minutes with a 20W adapter, and either charger can deliver that result. The phone and the charger talk to each other and agree on a safe power level, so the phone never takes more than it can handle. Charging also slows near 80% on any brand, since the iPhone protects its battery from heat. BGR notes that an iPhone 17e supports charging at up to 20W, so a stronger adapter adds nothing there. AvaNext also warns that higher advertized wattage does not always mean faster charging on every phone. Some newer Pro models can accept more than 20W, and for those a 30W charger such as the Anker Nano 30W may give a small advantage.
Apple has a simpler safety record, while Anker has a strong reputation with a few past problems. BGR points out that Anker recalled some chargers and power banks after reports of fires, though the company handled those cases openly and kept a decent name. Anker also takes part in the Only at Apple program, where it builds chargers that Apple sells under its own label. Many Anker chargers include built-in temperature monitoring, which adds a layer of protection during long charging sessions. Buy from an official store or an authorised seller in either case. Fake chargers are common online, and a cheap copy can damage a phone or cause overheating.
The retractable plug is the most practical difference in daily life. Anker's prongs fold flat, so the charger slides into a laptop bag, a jacket pocket or a travel pouch without scratching other items. Apple's prongs stick out, which makes the adapter feel bulkier in a bag. Both models have a single USB-C port, so neither can charge two devices at once. Apple stopped putting a charger in the iPhone box, so most buyers need to purchase one anyway. A smaller adapter is easier to carry between home, office and travel.
Most people use a charger in three places, like the bedside, the office desk and a travel bag. At the bedside, both models work equally well and the size difference hardly matters. On a crowded desk or a power strip, the smaller Anker leaves space for the plug next to it. During travel, the lower weight and folding prongs make Anker the easier choice. Frequent flyers often keep one charger in the bag at all times, and a compact model is simpler to remember and pack. Apple's larger body is still comfortable to hold and feels solid in the hand.
Apple sells its adapter through Apple Stores and authorized resellers, and its one-year limited warranty is easy to claim at a physical store. Anker generally offers a longer warranty on chargers, often around 18 months, though terms change by country and by seller. Check the exact policy before you pay. Anker chargers are widely stocked on Amazon and in local electronics shops, which usually means faster delivery and more frequent discounts. Apple stock is steady, yet the price rarely changes outside official promotions.

A 20W charger is enough for most iPhones, yet it is not the top option for every user. If you also own an iPad, a tablet or a small laptop, a 30W charger gives more room. The Anker Nano 30W is one example that 3C Easy Markham compares with Apple's 20W adapter. Apple also sells a 40W adapter aimed at newer iPhones, and AvaNext lists it as an option for buyers who want extra headroom. Extra power costs more, so pay for it only if your devices can use it.
Choose Anker if you want the best value and the most portable design.
Pick Anker for a lower price, a smaller body and retractable prongs.
Pick Apple for an official product, store support and an easy return process.
Pick a 30W or 40W charger if you own a newer Pro iPhone or a tablet.
Avoid unknown sellers, since a fake charger costs more in the long run.
For most people, the Anker 20W Nano offers the same speed at a lower cost.
1. Is Anker’s 20W Nano charger as fast as Apple’s 20W charger?
Yes. Both support up to 20W USB Power Delivery, so charging speeds are broadly similar on iPhones designed to charge at 20W. Actual performance depends on the iPhone model, battery level and charging conditions.
2. Is Anker’s 20W Nano charger smaller than Apple’s 20W adapter?
Yes. The Anker 20W Nano comes with a smaller and lighter design than Apple’s 20W adapter. Its retractable prongs also make it easier to pack in a travel bag, laptop sleeve or pocket.
3. Should you buy a 20W or 30W charger for a newer iPhone?
A 20W charger can be sufficient for iPhones that support charging around that level. A 30W charger provides additional headroom for compatible newer models and can also charge other devices such as iPads.
4. Does a higher-wattage charger charge every iPhone faster?
Not necessarily. Charging speed depends on the iPhone’s supported power input and charging system. A higher-wattage adapter can provide more capacity, yet the phone controls how much power it actually draws.
5. Is Anker a reliable alternative to Apple’s official charger?
Anker is a major third-party charging accessory brand and offers USB-C chargers designed for modern devices. Buyers should purchase from official or authorised sellers and check safety certifications, warranty terms and the exact model before buying.
