Godox A2: An $85 Xenon Flash That Snaps Onto an iPhone

A phone’s built-in flash is an LED, and the Godox A2 swaps that for a xenon flash tube on a magnetic mount that clips to the back of an iPhone. DPReview’s report on the Godox A2 puts it at $85, including a diffuser dome and carrying case. For phone photographers who have avoided flash because the built-in LED looks flat and harsh, it is a cheap test of whether real flash changes their pictures, with one condition: it only works through Godox’s own app.

What Happened

The A2 attaches magnetically to the back of a phone and connects over Bluetooth, with a stated range of up to 15 meters, so it can also be detached and used off the phone as a bounce or fill light. The magnetic ring attaches to any magnetic surface. Godox gives it a guide number of 15 and recommends staying within about 2 meters of the subject for best results.

A 3W bi-color modeling light with adjustable color temperature doubles as a focusing aid or a small video light. A 500mAh internal battery is rated for up to 400 full-power flashes. At launch it is iPhone-only, needing an iPhone 15 or newer on iOS 18 or later; Android and HarmonyOS versions are reportedly in development.

Why It Matters

The catch is control. The phone’s built-in camera app can’t trigger the A2, so every flash shot goes through Godox’s app, which offers an auto mode that sets flash power and exposure, and a fully manual mode. The Gadgeteer’s rundown lists manual flash power from 1/128 to full in one-third-stop steps and high-speed sync up to 1/8000 second, along with a recycle time of around 2 seconds at full power and USB-C charging in roughly an hour.

That design raises the questions DPReview leaves open. It is unclear how well the app works, whether shooting through it affects image quality, and how the flash interacts with the multi-shot and computational processing that phone cameras rely on. Our view is that these are not small details, since a phone’s look depends heavily on processing that a third-party app may not fully reach.

Read with Godox’s own 2-meter advice, the guide number of 15 suggests, in our reading, a close-range light for portraits, food and products rather than a way to light a room.

What This Means for Builders

For photographers already using small Godox lights, the A2 extends a familiar system to the phone. Stack Archive covered the brand’s pocketable camera option in Godox iM30Pro: A $45 Rechargeable Bounce Flash That Fits in Your Pocket. The A2 is a different bet, since it depends on an app replacing the phone’s own camera pipeline rather than a hot shoe.
