30W genuinely delivered, across several types of devices
The Nano 3 holds up to its advertised power: an iPhone 14 Pro receives around 20W, a Google Pixel 7 around 18.7W, and a MacBook Air M2 around 26.5W, values consistent with what you would expect from a 30W PD/PPS charger depending on the device plugged in. An iPhone charges from 1% to 50% in just over 30 minutes, and reaches 100% in around 1h30, matching the manufacturer's promise.
Foldable plug: only on the US version
This is the most important point to correct before buying. The Nano 3 comes in several regional versions depending on the mains plug format, and the foldable plug, often cited as a compactness argument, only applies to the version sold in the United States. The version sold in the UK and Europe has fixed prongs that do not fold flat against the case. The charger stays just as compact overall, but the foldable-plug argument does not apply outside the US.
Thermal safety and protection margin
Over a test of several hours at full power continuously, the case temperature stabilizes around 71 °C, with no drift toward thermal runaway: ActiveShield protection works as expected on this specific point. One nuance exists around the margin before cutoff in case of overcurrent: some units seem to tolerate a notable overshoot beyond the nominal 30W before cutting off, a margin a little tight against the industry's usual standards. This point deserves watching rather than being treated as a proven systematic issue, as the data available on this specific point remains limited.
Compatibility and everyday use
The Nano 3 handles USB PD and PPS correctly, which covers fast charging on recent iPhones, PPS-compatible Samsung Galaxy phones, Google Pixel and most USB-C devices. Its single port, however, limits use to one device at a time. No cable is included in the box, so you need to provide a suitable one (USB-C to USB-C, or USB-C to Lightning for older iPhones).
Price and availability
The observed price sits around £19, with frequent variation depending on colour and promotions, sometimes dropping under £15 during certain periods. No product recall was found for this model in the European and American safety databases consulted.
