When you travel as often as I do, certain pieces of gear become lifelines, and chargers are at the top of that list. I can get by with a smaller power bank or even a slim laptop bag, but the one thing that absolutely cannot fail is the charger. Anker’s Nano 70W, with its three ports and double GaN tech, has quickly moved from “extra brick” to “essential carry.” I first dropped it in my sling bag almost as a trial run, figuring it might come in handy if I wanted to shave some time off charging my iPhone 16 at the airport. By the end of the day, it had proved itself in a much bigger way.
The Exception
What makes this Nano stand out is balance. At 70W, it hits that sweet spot where it’s powerful enough to top off high-draw devices like the ROG Ally X and Steam Deck in around 23 minutes, while still being compact enough to tuck into the smallest side pocket. Anker includes a USB-C cable in the box—thick braided housing, no fraying edges—which I appreciated more than I thought I would. I’ve bought too many third-party cables over the years, and not once during my time with this charger did I feel like I had to swap it out for something “better.”
TÜV Rheinland certification isn’t just a marketing stamp either. I pushed this Nano hard: plugging in my Ally X, iPhone, and earbuds all at once while camped out in a busy café. The charger ran warm, never hot, which is more than I can say for the outlets themselves. Double-GaN keeps it efficient and cool, and the casing never gave off that worrying “plastic burn” warmth some lesser brands do when under load. It’s that kind of invisible confidence that separates the gear you trust from the gear you tolerate.
Tech Specs
- Power Output: Up to 70W total
- Ports: 2× USB-C, 1× USB-A
- Certification: TÜV Rheinland, Double-GaN technology
- Charge Speeds: iPhone 16 to 50% in 28 mins, ROG Ally X/Steam Deck ~23 mins
- Included Cable: USB-C (braided)
- Design: Compact, matte finish, wall-friendly profile
Design-wise, it doesn’t scream for attention. The finish is matte, the corners rounded, and the footprint minimal enough that it doesn’t hog the second outlet on a wall plug. That matters when you’re sharing space in a crowded lounge or hotel room. And unlike some higher-wattage chargers I’ve tested, it doesn’t tilt or sag when plugged directly into the wall. It feels tightly engineered, like a piece of gear built to travel.
What surprised me most is how seamlessly it became part of my daily rhythm. Instead of juggling separate chargers for phone and handhelds, I just dropped this Nano into the rotation and let it take care of business. I often forget to charge my phone at night before bed, so when I’m readying for work in the morning, I would connect this badboy and see my phone charge upwards to +50% in about 25mins — same if I was playing my Steam Deck, a fast boost while making a cup of coffee goes a long way; it handled every situation without complaint. Portable chargers often feel like compromises—small enough to carry but not strong enough to rely on. The Nano 70W doesn’t play that game. It travels light, but it plays heavy.
