Anker Nano II 65W (Anker 737) Review — 2026

Chargers are the quietest part of a travel kit—until they’re slow, hot, or too big. With a 65‑watt ceiling, Anker’s Nano II family replaces the brick that came with your laptop while shrinking to pocket size. For travelers, satisfaction hinges on five things: hitting rated wattage without drama, speaking the right fast‑charge protocols (USB PD/PPS), staying thermally controlled, being compact and durable for daily packing, and coping with edge‑case devices like power banks or projectors. Across thousands of reviews, teardowns, and protocol docs, the pattern is clear: the Nano II nails the first four and occasionally stumbles on the fifth.

In short: the Anker Nano II 65W (Anker 737) GaN Charger delivers laptop‑class power in a pocketable body, negotiating PD and PPS quickly. If you prize size and dependable single‑port output over multi‑device flexibility, it performs like a travel MVP over time.

What “performance” really means for a travel GaN charger

For a single‑port travel charger, performance is more than a 65W headline. It’s quick, correct PD/PPS negotiation across phones, tablets, and 13‑inch laptops; stable delivery at 20V/3.25A; tolerable heat in tight outlets; and a form factor that survives constant packing. The Nano II’s published spec hits those marks: PD fixed steps at 5/9/15/20V up to 65W, PPS support for compatible phones, dimensions around 1.65 × 1.42 × 1.74 in (about 3.96 oz), and foldable U.S. prongs. Those numbers mean it can replace common 61–67W OEM bricks—MacBook Air/Pro 13 and many ultrabooks—without hogging a pouch. Anker’s listing also calls out broad laptop compatibility, Samsung PPS support, and conformance to IEC 62368‑1, the safety baseline for this class. (Anker product page and specs.) (anker.com)

GaN power transistors are why this much output fits into this little case: they switch faster and more efficiently than silicon, raising power density while controlling heat—documented in third‑party teardowns of the 65W Nano II. (chargerlab.com) If you’re wondering why protocol support matters, the USB‑IF explains it: USB Power Delivery covers fixed 5/9/15/20V steps (laptops), while PPS lets phones and chargers fine‑tune voltage and current within limits (Samsung “Super Fast” modes). (usb.org)

How the Anker Nano II 65W (Anker 737) GaN Charger behaves in week one

Day one is plug‑and‑charge. Fold out the prongs, connect a USB‑C cable, and most USB‑C laptops immediately negotiate 20V, drawing what they need (often 30–60W during normal work). Anker cites MacBook Air and 13‑inch MacBook Pro among “high‑speed” matches; owners report this across Windows thin‑and‑lights such as Dell XPS 13 and Lenovo ThinkPad X390. (anker.com) For phones and tablets, the charger speaks standard PD for iPad and iPhone (device‑limited around 20–27W) and PPS for Samsung “Super Fast Charging,” but not the 45W “Super Fast Charging 2.0” profile. (anker.com)

In the first week you notice speed parity with many OEM 61–67W bricks and a clear weight/space win. You’ll notice warmth if you push a sustained 60–65W laptop load or rapidly top up a Galaxy phone—normal for compact GaN designs and shown in YouTube reviews. (youtube.com) Two setup tips cure most hiccups: use a certified 5A e‑marker cable for any laptop draw near 65W, and plug directly into a wall outlet (not an old power strip) when you need peak output; Anker and owners emphasize cable choice for stability. (anker.com)

Sustained performance over months: output stability, heat, and hardware wear

Across months, three patterns dominate reports. First, output stability holds up: once a device negotiates a PD profile, the Nano II maintains it without “hunting,” and it recovers cleanly from short power blips—behavior consistent with PD’s state machine and echoed by reviewers. (usb.org) Second, heat is present but managed: teardowns show dense, orderly internals and clear thermal paths; owners describe the shell as warm under sustained 50–65W but not alarming. (chargerlab.com) Third, the hardware usually shrugs off constant packing, though a minority of Redditors report bent or loosening folding prongs after drops or heavy travel—a folding‑plug trade‑off. (reddit.com)

Efficiency metrics in the user manual—average active efficiency near 87.7% and ~0.08W no‑load—align with modern GaN behavior, limiting idle heat once a device is full. (manuals.plus) Edge‑case compatibility crops up: certain power banks and a few projectors expect unusual voltage/current envelopes, leading to slower starts or renegotiations. Reddit threads catalog workarounds (swap the cable, plug device first, power‑cycle the charger) and confirm that most mainstream laptops and phones are unproblematic. (reddit.com) Independent reviews like The Gadgeteer’s reached a similar bottom line at launch: compact, well‑engineered, warm under heavy load.

Where it excels—and where owners hit the limits

The Nano II excels when you need one tiny brick that can truly replace a 61–67W OEM charger for solo‑device travel. It’s exceptionally compact, negotiates PD quickly, and supports PPS for modern phones, so you can charge a laptop, then a phone, without two chargers. (anker.com) Limits are clear: one USB‑C port only, and no Samsung 45W “Super Fast Charging 2.0.” Anker states both on the product page; you’ll still get standard “Super Fast Charging” under PPS on recent Galaxy phones. (anker.com)

If you’re weighing single‑port minimalism against multi‑port flexibility, here’s a spec snapshot of three popular options.

Item	PPS support	Foldable prongs	Multi‑device at once	Worldwide 100–240V input	Cable included in box
Anker Nano II 65W (A2663)	Yes	Yes	No	Yes	No
Google 67W Flex (dual USB‑C)	Yes	Yes	Yes	Yes	No
UGREEN Nexode 65W (2C+1A)	Yes	Yes	Yes	Yes	No

Why the PD/PPS handshake matters (and how to avoid common pitfalls)

USB Power Delivery defines fixed 5/9/15/20V steps; most ultraportables select 20V and vary current with workload. Programmable Power Supply (PPS) lets supported phones request fine‑grained voltage/current adjustments to improve efficiency and thermals. That’s why PD + PPS is the right combo for travel: MacBooks and most Windows ultrabooks get the expected 20V PD rail, while recent Samsung models draw efficiently under PPS. (usb.org)

Two practices prevent most issues. First, match the cable to the load: use a 5A e‑marker USB‑C cable for any laptop draw near 65W, and avoid non‑e‑marked or old USB‑A adapters that cap current—guidance Anker repeats. Second, know the Samsung nuance: the Nano II supports “Super Fast Charging,” not the higher‑power 10V/4.5A SFC 2.0 mode; outside of 0–30% sprints the difference is modest, but if you need SFC 2.0, pick a charger that explicitly lists it. (anker.com)

Travel usability, thermals, and safety confidence

For travel, the questions are simple: will it fit, and is it safe everywhere you plug in? On size, the Nano II is among the smallest 60–70W‑class bricks we could source dimensions for, and its foldable plug avoids snagging in a pouch. On power, universal 100–240V input covers hotel and airport outlets worldwide; just add the right plug adapter. (anker.com) On heat, expect a warm case during sustained 50–65W loads (rendering, recovering a drained laptop while in use); that’s how compact GaN units shed heat and is visible in teardown thermals and reviewer demos. (youtube.com) On safety, Anker claims conformance with IEC 62368‑1—the relevant international equipment‑safety baseline—welcome peace of mind for hotel wiring. (anker.com)

Alternatives and value context

Owner sentiment is strong—about 4.6/5 across ~7.7k public reviews—with Amazon buyers praising compactness and dependable 65W output, and expert blogs/YouTubers validating that with on‑camera tests and teardowns. Reddit’s dissent is useful, flagging occasional handshake weirdness with certain power banks or displays and a few prong‑wear anecdotes—trade‑offs with any tiny travel‑first brick. (Representative examples are in the sources below.)

If you want multiple ports, Google’s dual‑USB‑C 67W Flex and UGREEN’s 65W Nexode (2C + 1A) are practical alternatives, but both are larger and heavier by their own specs. Google lists 2.2 × 1.1 × 2.6 in and about 5.1 oz with PD 3.2 + PPS on both ports; UGREEN lists 2.6 × 1.57 × 1.22 in and 4.6 oz with PD + PPS. (store.google.com) The trade‑off: the Nano II maximizes density for one port, while multi‑port bricks trade compactness for flexibility. Here’s how that looks when you compare connection profiles and ports per cubic inch.

Get the best performance: a quick setup checklist

• Use the right cable. For laptop draws near 65W, pair the charger with a certified 5A e‑marker USB‑C to C cable so the 20V/3.25A profile isn’t current‑limited by the cable. (anker.com)
• Prioritize direct‑to‑wall connections when you need peak output; old power strips and loose adapters can cause voltage droop that forces PD to renegotiate to a lower step. (usb.org)
• For Samsung Galaxy S/Note/Ultra models, expect “Super Fast Charging” (PPS) and not “Super Fast Charging 2.0” (45W) with the Nano II; if you want SFC 2.0, choose a 45W PPS charger that explicitly lists 10V/4.5A. (anker.com)
• Pack a regional plug adapter, not a voltage converter; the Nano II accepts 100–240V at 50/60Hz worldwide. (anker.com)
• If a niche device (some projectors or power banks) won’t draw full power, swap cables first, then power‑cycle the charger; community threads suggest handshake order resolves many cases. (reddit.com)

Conclusion: consistent, compact, and travel‑ready

The Nano II’s value proposition proves out in practice: one of the smallest 65W chargers you can buy that behaves like a full‑size OEM brick for 13‑inch laptops and modern phones, day after day. If you don’t need to charge multiple devices at once or hit Samsung’s 45W SFC 2.0 mode, its real‑world performance—and the balance of praise versus the manageable complaints owners report—makes it an easy travel staple.
