The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Anker Nano Travel Adapter is the pick that r/onebag and r/Ultralight users reach for when packed size matters more than wattage. A high-trust write-up at packhacker.com describes it as "slim, stable, and super packable," and an r/anker thread highlights that it's only about 2.5cm (1") thick — flat enough to slide into a clothing pocket. A verified-purchase r/onebag commenter reported it "worked perfectly" through two weeks in Japan, and bestbuy.com verified-purchase reviews echo the portability case.
What reviewers liked
- packhacker.com (high-trust expert) and r/onebag verified users praise the slim, packable form factor
- Only ~2.5cm thick — flatter than most universal adapters
- Retracting prongs and stable seating in outlets per Best Buy verified-purchase reviews
- Five ports including 2 USB-C and 2 USB-A handles a phone/watch/earbuds/tablet load
Where it falls short
- Total USB output capped around 20W — not a laptop charger
- r/anker users specifically call out the USB-A ports as underpowered
- An r/UsbCHardware thread raises a port-damage caution with Anker USB-C chargers — uncorroborated elsewhere but worth noting
- No surge protection
Across the reviewers we read, the Anker Nano Travel Adapter is the pick that r/onebag and r/Ultralight users reach for when packed size matters more than wattage. A high-trust write-up at packhacker.com describes it as "slim, stable, and super packable," and an r/anker thread highlights that it's only about 2.5cm (1") thick — flat enough to slide into a clothing pocket. A verified-purchase r/onebag commenter reported it "worked perfectly" through two weeks in Japan, and bestbuy.com verified-purchase reviews echo the portability case.
The consensus criticism, raised on r/anker itself, is that the four USB ports share only 20W total (15W when split), so this is firmly a phone-and-accessories adapter, not a laptop charger. More seriously, an r/UsbCHardware thread titled "Caution with Anker chargers" reports devices' USB-C ports being damaged after use — that's a single thread on a medium-trust subreddit and isn't echoed elsewhere in the data, but it's worth surfacing rather than burying. For travelers carrying mostly USB-powered gear, the size-to-capability ratio is still the best in this roundup.
- Universal Plug Compatibility
- Type A (US / Canada / Japan / China), Type C (EU), Type G (UK / Singapore), and Type I (Australia).
- Power 5 Devices at Once
- Includes 1 AC outlet, 2 USB-A ports, and 2 USB-C ports. The USB ports support up to 20W total output or 15W max when shared. A single USB-C port delivers up to 20W and charges iPhone 16 to 50% in 28 minutes. The maximum current is 6A.
- Exceptionally Compact
- Measuring just 3.39 × 1.97 × 0.98 in (86 × 50 × 25 mm), it has a credit card-sized footprint and is 43% smaller than similar models. See image 4 for the size comparison. Foldable and retractable pins make it even easier to carry.
- 2-Pin to 2-Pin Connection
- The safe 2-pin design helps reduce the risk of electric shock for worry-free travel. The AC outlet does not support 3-prong grounded plugs, including EU Schuko, UK 3-pin, or grounded laptop chargers.
- What You Get
- 1× Anker Nano Travel Adapter (5-in-1, 20W), welcome guide, 18-month warranty, and our friendly customer service.
- Note
- No voltage conversion.
The USB-A ports are a pretty big disappointment to me, I wish this had all USB-C ports . 15W shared across 4 USB ports is really ...
EDIT: I tested it 2 weeks in Japan and it worked perfectly well, no problems at all. I have to say, from now on the Anker Nano Travel Adapter is ...
