Best Wireless Charger NZ: Which to Buy

Wireless charging wattage numbers on the box rarely match what your phone actually pulls. Here's what determines real-world charging speed, and whether a pad, stand, or multi-device dock suits you.

The wattage on the box is not what you get

A charger advertised as "15W" only hits that figure with a specific phone, a compatible charger brick, and perfect coil alignment — and even then, only some phones accept 15W wirelessly at all. Most iPhones cap wireless charging around 7.5-15W depending on model and whether you're using a Qi2 or MagSafe-certified charger with an appropriately rated USB-C power adapter (the charger itself usually doesn't come with one). Many Android phones cap lower again unless you're using the phone maker's own charger. Treat the wattage on the box as a ceiling under ideal conditions, not a promise.

Qi2 and why alignment matters more than watts

Qi2 is the newer wireless charging standard that builds in a magnetic alignment ring, similar to Apple's MagSafe. The magnets snap your phone into the exact centre position over the charging coil every time, which matters because misalignment is the single biggest cause of slow or failed wireless charging — a pad rated for 15W delivering 5W because the phone is sitting 1cm off-centre is extremely common with older Qi chargers and no magnets.

• Qi2 or MagSafe-certified chargers: best real-world charging speed and consistency thanks to magnetic alignment, works with iPhone 12 and later and a growing number of Qi2-certified Android phones.
• Standard Qi chargers without magnets: cheaper, but you have to manually find the sweet spot on the pad, and it's easy to nudge it out of place.
• Check your phone's actual specs before buying — not every phone supports fast wireless charging, and a premium charger won't speed up a phone that only accepts 5W wirelessly.

Charging stand vs pad vs multi-device

A flat pad is the cheapest option and fine for a desk where the phone just needs to top up while you work. A stand angles the phone upright, which is genuinely useful if you want to see notifications or use Face ID while charging, or prop it up for video calls. Multi-device chargers (phone plus earbuds plus watch) are convenient for reducing cable clutter on a nightstand, but they usually charge each device slower than a dedicated single-device charger would, since they're splitting a shared power budget — factor that in if fast overnight charging matters to you.

A quick sanity check before buying

• Confirm your phone case is wireless-charging compatible — thick cases, wallet cases, and some MagSafe-incompatible cases will slow or block charging entirely.
• Check the included cable length if you're wall-mounting or using it somewhere the plug is far from a wall socket.
• A 20W+ USB-C wall adapter is often needed separately to actually reach a charger's maximum rated output — many chargers ship without one.
