I buy only from these approved sources. I can't vouch for ads below. |
This is a very clever little flash. It has all the features we need for most on-camera use, except that it has so little power that it only reaches a few feet. While it may be useful indoors at high ISOs and for outdoor fill flash for macro and closeups, it lacks the power to work as fill at most distances in daylight.
The Godox iT20 is an excellent little flash to use in-studio to trigger large manual studio strobes. Even at 1/32 power it easily fires my manual studio strobes. If you only need a tiny manual flash, the iM20 is the manual-only version of this tiny flash. The iM20 sells for only $34 and works on every camera with a hot shoe.
It has no ability to tilt for bounce flash; it doesn't have the power.
The Canon version I show here has a better shoe lock than Canon's own flash! Just slide it in and it clicks and locks, and just push the release button to unlock. Why can't camera-brand flash be this easy to lock and unlock?
Here's how small it looks atop a DSLR:

It charges over USB.
Even if totally dead, mine completely recharges in 64 minutes.
It includes a USB-A to USB-C cable, and charges with that or USB-C to USB-C cables from anything like a car USB outlet, a USB solar panel, or any other USB source like a USB charger, USB power bank or car 12V USB charger.
Simple Controls & OLED display. bigger.
Hold the power (⏻/↯) button a second to turn on or off. Tap (press and release it quickly) to test-fire.
It has but two modes: TTL and Manual. Just tap the M button to swap between them.
TTL Exposure Compensation and Manual power levels are selected with the + and - buttons.
The OLED display clearly shows what's going on. It even lets you know when you have a data connection with your camera with a tiny camera icon on the OLED.
The OLED display is perfect indoors, but dim outdoors in shade and illegible in direct sunlight. Even shielding it with your hands outdoors it's not easy to read, but that's OK because the flash itself is so weak I doubt it would serve much purpose except for close-ups in daylight.
If it fires at full TTL power (which is most of the time), if you look quickly at the OLED it will say MAX for about one second as it recycles.
It automatically reverts to standby mode if ignored, during which every 2⅔ seconds it will blink a moon icon for a half second. It will stay in standby about ten hours, after which it shuts off. Sadly I can't imagine why I'd want it in standby for ten hours (it has no remote control or slave ability), and after ten hours it's drained about half of the battery — sort of defeating the purpose.
Godox iT20 Included Accessories. bigger.
It includes a USB-A to USB-C charge cable, a soft pouch to hold the flash and accessories, and a set of three brilliant magnetic filters (CTO, ½ CTO and an ultrawide diffuser):

Included Ultrawide Diffuser. bigger. |
Included ½ CTO filter. bigger. |
An orange CTO, or "Color Temperature, Orange," filter converts daylight (5,500K) to tungsten (3,200K). We use this filter when using the flash indoors under tungsten light. With our camera's white balance set to tungsten, the light from the flash fill matches the ambient light. Without this filter, the ambient background will look orange, or if the camera is set to tungsten white balance then an unfiltered flash will look blueish.
The ½ CTO filter is to make the flash only half as warm. Use this to make the flash match warm sunset light. Without the ½ CTO filter at sunset the flash will again look cool and bluish in comparison.
The magnetic system is so clever that we can stack the filters, or stack them upside down to keep them on the flash while not in use.

It even includes a small packet of silica gel for shipping.

Power Output (Actual Measurements)
I measure Guide Number 10 feet (3 meters) at ISO 100.
Godox doesn't specify power output.
This is so little power that at only five feet (1.5m) you'd need to shoot at f/2 at ISO 100.
I measure GN 6 feet (1.8 meters) with the included diffuser.
Recycling Time (Actual Measurements)
1.5 seconds.
With a mostly dead battery, it takes 2.1 seconds.
Super!
Charging & Power (Actual Measurements)
It charges via USB-C from any source I can imagine, either new (USB-C) or old USB-A (the bigger rectangular connector).
It recharges from completely dead in 64 minutes.
It draws 2.6W (520 mA at 5V) via USB-C while charging.
When full, it draws 54 mW (10.6 mA at 5V).
A full charge consumes 2.724 Wh, measured.
It will work while it's charging.
Easy!
Size (Actual Measurements)
31.08 x 41.12 x 40.09 millimeters, HWD.
1.2236 x 1.6189 x 1.578 inches HWD.

It's super easy and fast to use. I love everything about this tiny wonder, except that it has such little power it's not what I need as a carry-everywhere flash for daylight fill-flash.

For Nikon I still prefer my twenty-year-old Nikon SB-400, for Canon I love my 320EX and for any of them the Sunpak RD-2000 works well as a tiny flash with enough oomph for daylight fill-flash.
The weakest of these still has twenty times more power than this tiny Godox iT20.
Thus my search continues for a modern, tiny, carry everywhere flash for easy daylight fill-flash. This is a gem if you're close or want the tinest possible flash.
