I would also be helpful if they included other ways to charge. ### ⭐⭐⭐ Light it up. *by on Reviewed in the United States January 28, 2026* I've only rated this with 3 stars as I haven't used it much, nor have I developed the photos. I had a Vivitar but that conked out. I decided to try this as I've cut done my photography, especially indoors. It seems to provide the same light output as the Vivitar unit I had and fits my Olympus 35mm just fine. I do like that it's smaller than the Vivitar & fits in my camera bag well. ### ⭐⭐⭐⭐ very basic *by on Reviewed in the United States November 4, 2024* No options for distance or angle- one trick pony, but it does that trick okay. ## Frequently Bought Together - Hersmay CY-20 Universal Camera Speedlight Flash Hot Shoe Mount On-Camera Electronic Speedlight with Sync Port for Nikon/Canon/Panasonic/Olympus/Pentax Alpha Digital DSLR Camera Flash Light - Kodak 120 Portra 400 Film - Holga 120N Plastic Camera --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/454594316-hersmay-cy-20-universal-camera-speedlight-flash-hot-shoe-mount](https://www.desertcart.ph/products/454594316-hersmay-cy-20-universal-camera-speedlight-flash-hot-shoe-mount) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-16*
