<summary>Question: How powerful is the flash?</summary>
<div>
Answer: **Guide Number 8 at ISO 100** — think of this as a portable fill/accent flash, NOT a main strobe. Useful range ~1-2m for product, macro, table-top food shots, or as a pop-on-camera fill light. For full-room lighting or wedding-flash use, look at the SL01/SL02 (higher GN) or any Godox V-series.

<summary>Question: Will it work with my camera — Sony, Canon, Nikon, Fuji?</summary>
<div>
Answer: Yes — **universal single-contact hot shoe**. Triggers off the center-pin of standard ISO-518 hot shoes, which is universal across Sony Alpha, Canon EOS, Nikon Z/F, Fuji X, Panasonic, OM System, Olympus, Pentax. Note: only the **center-pin trigger** fires — no TTL communication. You manually set the flash output.

<summary>Question: Does it support TTL (auto exposure)?</summary>
<div>
Answer: **No — manual only.** You set the power level directly (1/1, 1/2, 1/4, 1/8, etc.). For a $24.99 flash this is normal — TTL on-shoe units start around $60. The trade-off: simpler, smaller, longer battery life. Workflow: set ISO + aperture + shutter on camera, dial flash power until exposure looks right.

<summary>Question: What's recycle time — can I shoot bursts?</summary>
<div>
Answer: **2.5s at full power, 0.8s at 1/4 power, near-instant at 1/16 and below.** So for street/event burst shooting at low power, no waiting. For full-power product shoots, expect roughly 1 shot every 2.5 seconds. Battery delivers ~500 flashes at full power before USB-C recharging needed.

<summary>Question: Can it work as a continuous video light too?</summary>
<div>
Answer: Yes — has **3 modes: flash / constant light / flash + fill**. The constant light mode outputs ~1W at 5600K±200K, suitable as a focus assist in low light, or as a small key light for phone macro / Pocket 3 close-ups. Battery in constant mode lasts notably longer than flash mode.

<summary>Question: How is it charged?</summary>
<div>
Answer: **USB-C, 5V/1A, ~1 hour to full** from empty. Internal 300mAh battery — same as a wireless earbud case. No AA batteries needed, no swapping, but you can't extend runtime by swapping cells in the field. Carry a USB-C power bank for shoot days.

<summary>Question: Ulanzi SL03 vs. Godox iM30: Which mini flash should I choose?</summary>
<div>
Answer: Choose the **Ulanzi SL03** if you want a lighter, more versatile everyday flash. It weighs 43g, tilts up to 90° for direct or bounce lighting, adds a 1W high-CRI continuous light, recycles in about 2.5 seconds at full power, and delivers at least 500 full-power flashes from its USB-C rechargeable battery. Choose the **Godox iM30** if direct-flash output is your priority: its published GN15 is about 1.8 stops stronger than the SL03's GN8, and it offers seven manual power levels, S1/S2 optical triggering, a sync port, and replaceable AAA batteries. The trade-offs are a fixed flash head, no continuous light, and an approximately 3.6-second full-power recycle time. Both use a universal single-contact hot shoe and are manual-only, with no TTL or HSS. For cameras such as the Canon 600D or Ricoh GR III, pick SL03 for bounce lighting, USB-C convenience, and hybrid photo/video use; pick iM30 for stronger direct flash and built-in optical slave control.

<summary>Question: Will it fit hot-shoe-less cameras (Sony ZV-E10, GoPro)?</summary>
<div>
Answer: Not directly — hot shoe required. For hot-shoe-less bodies, use a cold shoe extension on the side of the cage / rig and trigger SL03 manually with a sync cable, or use it free-standing in constant light mode as a small LED rather than as a flash.
