Digital Camera World Verdict

The Anker Nano 3 stands as a compact powerhouse. Thanks to GaN tech, Anker has managed to shrink the plug's size to unprecedented levels while still delivering ample power to charge a MacBook Air or fast-charge a phone or tablet. If you happen to be reading this within the United States, the convenient folding prong design makes this power adapter remarkably compact. However, for the rest of the world, the bulky upfront plugs do somewhat compromise its aesthetic appeal. But regardless of your geographical location, this diminutive 30W plug performs admirably, charging my iPhone 14 Pro in roughly an hour and a half, and sustaining my MacBook Air (M2) even during demanding usage. If your device lineup consists mainly of lower-powered gadgets, this plug is a stellar choice for on-the-go use.

Power adapters are certainly not the most exciting technology purchase you can make, although they might just be one of the most essential. We all need to keep our various devices and every increasing number of devices topped up with power, and with fewer and fewer devices coming with power adapters in the box it is up to us to figure out the best way to keep our devices powered up.

There are a few things to consider when picking a charger, primarily do you want to prioritze how small your charger can be, or how many devices you want to charge. If you said you’re looking for as small as possible and only one device at a time, then the Anker Nano 3 might just be what you are looking for. As the Nano name suggests, Anker has made this plug as miniature as technology (and sockets) will allow, while still providing 30W of power which is more than the maximum power draw for most small devices like phones, wearables, and tablets.
