Low smartphone battery levels are a serious pain point for business travellers, so it's no surprise that Apple's promise of fast-charge technology in the new iPhone 8, 8 Plus and iPhone X models will be a drawcard for many buyers of the shiny kit.
Already an established feature of the best Android smartphones, fast-charging lets you quickly top up the battery with just a short period plugged into any handy AC socket.
Apple says the iPhone 8, 8 Plus and iPhone X will juice up from flat to 50% (which translates to about another six hours) in just 30 minutes – which could be a brief recharge in an airport lounge, during a meetings or even at the local cafe.
But here's the catch: Apple won't provide the necessary fast-charge kit in the box, even if you shell out a hefty $1,829 for the flagship iPhone X.
Instead, you'll need to buy a special Apple charger fitted with a USB-C connector – the same type of connector which enables fast-charging on the likes of Samsung and Huawei phones, and which those phones bundle from the get-go.
Apple sells three USB-C chargers rated at outputs of 29 watts, 61 watts and 87 watts – which sell from to $69 to $109, although it's unclear if the modest 29W charger has sufficient oomph to deliver the promised "zero-to-50% in 30 minutes" capability.
Oh, and you'll also need a USB-C to Lightning cable to connect the USB-C AC charger to your iPhone. That's another $35, thanks.
