In this guide
Buy this Nano to add one charging point where you actually need one. For $15.99 that is a sensible thing to put beside a bed or in a day bag. As a replacement for a whole charging setup it disappoints on the first night.
Write down what actually gets plugged in after a day out. Phone, headphones, watch, laptop: four things, none of them demanding, and a queue all the same. The friction is the number of connections, not the wattage on the label.
Our verdict
Good value for a compatible phone or similar single-device job; a limited choice as your only travel charger.
- A good fit for
- Someone who needs one small USB-C charging point and already has a suitable cable.
- We would skip it if
- You charge several devices together or your laptop requires substantially more than 30W.
Reasons to consider it
- A compact body is easy to allocate space for
- The specified USB-C outputs cover several charging profiles
The compromises
- One port means serial charging when several devices need power
- The wattage label does not predict a device-specific charging time
What we have not verified: Charging speed, efficiency, heat under load and electrical performance: none measured here.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Nano Charger 30W · A2147
A sensible second charging point when the larger adapter is awkward to pack.
Before you buy: Confirm the device requirement and the cable. One 30W port does not replace a laptop adapter.
Price checked September 10, 2026. Retailer prices can change.Thirty watts describes the ceiling, not every charge
Anker specifies one USB-C port with a 30W maximum, fixed output profiles from 5V to 20V, and PPS support. The listed body measures 1.12 by 1.12 by 1.39 inches. Those specifications establish the intended size and output range; they do not establish how quickly your own device will charge.
Start from what the device asks for; the charger and the cable both have to support it. Paying for a bigger number to charge a pair of earbuds is waste, and a phone charger will not hold a laptop up through a compile.
The travel test is the moment everything is empty
Picture arriving late with a low phone and another device needed in the morning. If you cannot charge both until one finishes, the smaller adapter has traded luggage space for attention. That can be reasonable for a light packer and irritating for someone who simply wants to plug everything in and sleep.
It suits a one-device trip, or life as a dedicated phone charger by the bed. For a bigger kit, price the whole arrangement — adapter, cables, sockets available, second charger — because one slightly larger multiport brick often takes less room than three small ones loose in a pouch.
An existing working adapter may be the better deal
If a current adapter already reaches the places you charge and meets the device requirements, keeping it costs nothing. The Nano needs to remove an actual inconvenience: an oversized plug, a missing charging location, or the daily task of moving one adapter between rooms.
Include a suitable cable in the comparison if you do not already own one. Also inspect the physical outlet location and cable route. A compact body cannot fix a socket hidden behind furniture if the cable has no sensible path out. These mundane details decide whether a small accessory earns daily use.
Our recommendation stays attached to A2147
Anker uses the Nano name across multiple products. This assessment concerns the A2147 listing, not every charger with a similar name or advertised wattage. Confirm the model and regional plug when comparing sellers; the photographed version here has US prongs.
Recommended where the charging job is bounded and the delivered price stays modest. A multiport alternative that clears your whole evening queue for similar money is the better buy. Temperatures and charging behavior went untested here, and a manufacturer's protection branding is not a safety verdict.
