Anker 20W USB-C Charger Review: Compact Power Verdict
The Anker 20W USB-C Charger 2-Pack has built a reputation for combining portability, speed, and reliability—earning an aggregated score of 9.6/10 from cross-platform user feedback. While marketing emphasizes lightning-fast charging and premium build quality, thousands of verified buyers across Amazon, Trustpilot, Reddit, and eBay confirm those claims in most scenarios, with only a few caveats for cable compatibility and extreme power demands.

Claims vs Reality
Claim: “20W High-Speed Charging”
Anker advertises the ability to power an iPhone 14 from 0–50% in 30 minutes. According to Amazon reviews and Trustpilot reports, this is accurate when paired with the right cable. One Amazon customer noted that using an Apple-certified USB-C to Lightning cable unlocked noticeably faster speeds compared to generic MFi cables. However, Reddit threads reveal Android users with Samsung S-series phones saw normal fast charging but not the brand’s “Super Fast” mode, aligning with Anker’s own fine print.
Claim: “Dual-Port Charging Without Compromising Speed”
The marketing implies simultaneous charging doesn’t slow things down. In community discussions, users found that while single-port charging delivers the full 20W on USB-C, using both ports drops total output to 15W—enough for two phones overnight but slower for quick top-ups. A Trustpilot reviewer using it for an iPhone and iPad simultaneously described it as “steady and safe, but not blazing fast in dual mode.”
Claim: “Compact & Travel-Friendly”
Anker promotes portability as a major selling point. Cross-platform feedback supports this—multiple buyers praise its fit in tight spaces, from airplane seat power outlets to bedside tables. One eBay buyer who purchased an open-box unit said it was “small enough to toss in a jacket pocket,” though some noted it’s slightly larger than the Anker Nano single-port model.

Cross-Platform Consensus
Universally Praised
Portability is the standout praise. Trustpilot reviewers consistently highlight the ease of carrying two chargers in minimal space, making them perfect for business trips or family vacations. Amazon users emphasize pairing them with Anker’s included 5 ft cables for optimal reach in hotels and airports.
Fast charging performance for Apple devices is another win. Reddit user u/TravelFilmGuy shared that charging his iPhone 13 for 15 minutes before a train ride gave him “enough juice for a 3-hour video binge.” This mirrors Anker’s claim of short bursts delivering meaningful runtime.
Build quality earns repeated commendations. Buyers describe the chargers as “solid cubes” that withstand daily plugging/unplugging without loosening ports. Trustpilot sentiment shows confidence in Anker as a brand, with many replacing OEM Apple bricks entirely.
Common Complaints
Cable compatibility stands out as the most frequent frustration. Several Amazon customers initially believed the charger was underperforming, only to discover that non-certified cables capped speeds. A reviewer updated their rating after switching to Apple cables, noting “instant speed boost.”
Heat buildup during prolonged single-port use surfaces occasionally—though most say it never approaches dangerous levels. One Trustpilot user reported the charger becoming “warm to the touch after 40 minutes on an iPad Pro,” but still performing reliably.
Lack of foldable prongs divides opinion. Travelers who value extra luggage space wish for collapsible plugs, while others accept the fixed design as a trade-off for durability.
Divisive Features
Dual-port output is both appreciated and questioned. For households, the ability to charge two devices overnight is a major convenience. Yet power users—especially those topping up during short breaks—criticize the performance drop from 20W to 15W total.
Size perception also varies. Some see it as ultra-compact compared to traditional bricks, while others, especially Nano owners, consider it “slightly chunky.”

Trust & Reliability
Trustpilot’s review pattern shows minimal deceptive activity, with over 80% high-quality reviews. Users report consistent performance over months, though durability beyond one year receives mixed marks—some units hold up flawlessly, others fail after heavy travel.
On Reddit, owners returning after six months note “no loss in charging speed” and ports remaining tight. The main wear point appears to be cables rather than the brick itself.
Alternatives
Within Anker’s lineup, the Nano single-port model earns favor for ultra-minimalists, sacrificing the second port for a smaller footprint. Apple’s 20W USB-C charger offers identical single-port output but at a higher price with no bundled cables. For multi-device power users, higher-output models like Anker’s 33W or 45W chargers give faster dual-device charging but are larger.
Price & Value
Amazon lists the 2-pack with cables around $27.98, often discounted to ~$22 with coupons. eBay open-box deals dip to $18–20, while new units trend higher in retail stores. Users consistently call it “great value,” with the 2-pack covering both home and travel setups. Resale value remains decent—used units on eBay fetch ~60% of retail if functional and clean.

FAQ
Does this charger support Samsung Super Fast Charging?
No, it supports standard fast charging but not Samsung’s proprietary “Super Fast” mode found on newer Galaxy devices.
Can I use it to charge my MacBook?
Not recommended. At 20W, it can charge slowly if the device supports USB-C charging, but it’s insufficient for laptops requiring higher wattage.
Is it safe to use overnight?
Yes. Anker’s MultiProtect safety system includes temperature control and overcharge protection, making it safe for overnight charging of phones and tablets.
Will it fast charge with any USB-C cable?
No, you need a high-quality, preferably manufacturer-certified cable (USB-C to Lightning for Apple devices) to achieve maximum speed.
Can I charge two devices at full speed simultaneously?
No. Dual-port mode reduces total output to 15W combined, slowing charge times compared to single-port use.
Final Verdict
Buy if you’re an Apple or Pixel user who values compact design, reliable fast charging, and the convenience of a dual-port setup—especially when traveling. Avoid if you rely on Samsung’s highest-speed charging or need power for laptops. Community tip: pair it with certified cables to unlock its full potential and avoid speed disappointments.
