Anker Nano 30W USB-C Charger (511, Nano 3) Review
A cafe stop is often the only mains power on a bikepacking trip, and a 30 W charger refills a phone in the time a coffee takes. The Nano is small enough to live in a top tube bag for good.
The verdictThe smallest fast charger worth carrying. Pair it with one good USB-C cable and a power bank.
The Amazon US listing, sold by AnkerDirect and shipped by Amazon, is Anker's 511 Charger (Nano 3, 30 W), model A2147, in white. It has one USB-C port, folding US prongs, gallium nitride (GaN) internals and a listed weight of 1.6 oz (45 g). There is no cable in the box, so budget for a USB-C cable that suits your devices.
Thirty watts covers full-speed charging for current iPhones and Samsung's 25 W Super Fast Charging, and it will refill a USB-C power bank or GPS between rides. Anker claims an iPad Air (5th generation) reaches 50 percent in 45 minutes, and a MacBook Air will charge, slowly. The single port is the trade-off, so the phone and the power bank take turns at a short stop.
Owner reports stood at 4.8 stars across 20,470 ratings in October 2026, and owners mostly praise the size and the folding prongs. A four-star review described awkward warranty logistics that Anker then resolved, and the listing itself gives the warranty as 24 months in one place and 18 in another. US prongs mean a travel adapter for riding abroad.
