Expert Review Analysis

The Ulanzi SL01 Mini Flash Speedlite is an ultra‑compact, 33 g manual flash offering GN 8 output, high CRI 96 colour accuracy and USB‑C rechargeable power. It targets beginners, travel shooters and mobile creators who need a lightweight, pocket‑sized fill light without TTL or bounce features.

✓ Best for: Beginners, travel photographers and mobile content creators who need a tiny, easy‑to‑use fill flash for still photography or short video clips. Ideal for street/walk‑around shooting, hot‑shoe mounting on compact cameras or smartphones, and low‑power continuous flash (1/8) in burst mode.✗ Not ideal for: Professional photographers or videographers requiring TTL auto‑exposure, high‑output GN, bounce or tilt capabilities, or integrated video lighting. Not suited for fast‑action sports or studio work where rapid full‑power recycling is essential.

Pros

✓Ultra‑compact size of 43×35×28 mm and weight of only 33 g makes it truly pocket‑sized for travel.
✓High colour rendering index of 96 delivers accurate, natural‑looking daylight‑balanced illumination.

SL01BlackSL01 Mini Flash Speedlite 1 YEAR WARRANTY

USB‑C rechargeable 250 mAh battery provides up to 375 full‑power flashes and unlimited runtime when plugged in.

✓Four manual power levels with continuous flash at 1/8 power enable fast recycling for burst shooting.

✓Simple single‑button operation with clear red/green LED indicators ensures reliable manual control.

Cons

✗Lacks any TTL or automatic exposure control, limiting flexibility for dynamic lighting situations.
✗Full‑power recycling time of up to 5 seconds can be slow for fast‑moving subjects or event photography.
✗No bounce head, tilt or diffusion accessories, restricting the ability to soften or redirect light.
✗Only manual flash mode; no built‑in video light or continuous lighting feature for video creators.
✗Official flash count rating of 375 flashes may be lower than some user‑reported numbers, causing uncertainty.

From Expert Reviews

Praised by Experts

✓Reviewers highlight the SL01 as the tiniest 33 g flash on the market, ideal for beginners and travel photographers.
✓Professional tests note the CRI 96 and 6500 K colour temperature provide clean, natural colour reproduction.
✓Editors praise the USB‑C charging that delivers a full charge in about one hour, enabling unlimited on‑the‑go use.
✓YouTube pros commend the four power levels and fast recycle at lower powers, making it effective for entry‑level speedlite work.

Criticized by Experts

✗Experts point out the absence of TTL auto‑exposure, which is standard on most competing speedlites.
✗Professional reviewers mention the 5‑second full‑power recycle as a drawback for high‑speed shooting.
✗Critics note the lack of a bounce head or tilt mechanism, limiting creative lighting options.
✗Editors observe that the SL01 offers only flash output, missing the video‑light feature found in the SL02/SL03.

From User Reviews

Users Love

✓Everyday users love the pocket‑size design, calling it perfect for everyday carry and travel.
✓Customers appreciate the simple button toggle and green ready light, saying it’s easy to use on the go.
✓Creators on TikTok and Reels mention the accurate 6500 K colour and high CRI for consistent content lighting.
✓Users highlight the long battery endurance, noting 375+ flashes and fast USB‑C charging as a major benefit.

Users Complain About

✗Users frequently complain about the manual‑only control, wishing for TTL or auto modes.
✗Many customers report the full‑power recycle delay of 3–5 seconds as inconvenient for fast shooting.
✗Consumers note the missing video‑light and bounce features, desiring upgrades like the SL02/SL03.
✗Some reviewers mention occasional discrepancies in flash count claims, with tests showing up to 500 flashes versus the official 375.

Expert Opinion

Professional reviewers praise the SL01 for its unprecedented miniaturisation, high CRI and convenient USB‑C charging, positioning it as a budget‑friendly entry‑level speedlite for beginners and travel shooters. However, they consistently note the lack of TTL, bounce capability and video lighting, which limits its appeal for more advanced or video‑centric workflows.

What Users Say

Everyday users celebrate the flash’s pocket‑size portability, straightforward operation and reliable battery life, especially for social‑media content creation. Recurring complaints centre on the manual‑only nature, the relatively slow full‑power recycle, and the absence of bounce or video‑light functions that competitors provide.

Common Complaints

Slow full‑power recycling (5 s), manual‑only control without TTL, lack of bounce/tilt or video‑light features, and occasional confusion over the official flash‑count rating versus higher user‑reported numbers.

How It Compares

vs. Ulanzi SL02

Advantages

✓Adds constant video light (5600 K, 200 lux) while keeping similar size and battery life
✓Slightly higher weight still under 40 g
✓Same 375‑flash battery capacity

Disadvantages

✗No TTL or bounce, still manual‑only for flash
✗Recycling time identical to SL01 (5 s full power)
✗Slightly larger dimensions than SL01

Choose SL02 if you need a hybrid photo/video flash and can tolerate a modest size increase; stick with SL01 for the absolute smallest pure flash.

vs. Ulanzi SL03

Advantages

✓Includes 90° bounce head and video light for more versatile lighting
✓Similar battery performance to SL01
✓Retains compact form factor compared to larger speedlites

Disadvantages

✗Larger than SL01 and a bit heavier (~40 g)
✗Still lacks TTL and automatic exposure control
✗Price is higher than the basic SL01

Select SL03 when you want added bounce and video capability and are willing to trade a bit of size; otherwise SL01 remains the lightest option.

vs. Godox Mini (e.g., V1 alternative)

Advantages

✓Offers TTL auto‑exposure and higher guide number (up to GN 12)
✓Faster full‑power recycle (2–3 s)
✓Generally more feature‑rich for advanced users

Disadvantages

✗Heavier and larger (~50 g, ~60 mm length)
✗Often lacks USB‑C rechargeable battery, relying on AA cells
✗Less pocket‑friendly than SL01

Opt for Godox Mini if you need TTL, higher output and faster recycle; choose SL01 for ultra‑compact, USB‑C powered simplicity.
